2 Observing Safety Guidelines Mi7 Central Office Engineering and Planning Guide

Installation Information and General CautionsInstallation and operations personnel should be aware of the following information:

• Equipment is intended for installation in a restricted access location.• Only qualified service personnel are allowed to service this system.• A readily accessible disconnect device must be incorporated in the building installation

wiring.• When requested, instructions and equipment marking related to safety shall be in a

language that is acceptable in the country in which the equipment is to be installed.• This device complies with Part 15 of the FCC rules. Operation is subject to the following

conditions:– This device may not cause harmful interference.– This device must accept any interference received, including interference that may

cause undesired operation.• The standards that dictate our optical safety labeling requirements are IEC 60825-1

(Edition 1.2 2001-08), FDA 21 CFR 1040.10 (4-1-97 Edition), and FDA Regulation CDRH Laser Notice No. 50 dated July 26, 2001.

• The following laser safety standards classify the Mi7:– Class 1M LASER PRODUCT (IEC 60825-1 2001-01) – Class I LASER PRODUCT (21CFR 1040.10 and 1040.11)

• Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard.

Using Optical FibersOptical fibers are either single mode or multi-mode. The following information applies to all optical fibers.

DANGER: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

DANGER: Risk of laser radiation exposure.

2-2 Installation Information and General Cautions © 2001-2004 Mahi Networks, Inc. All Rights Reserved.


Mi7 Central Office Engineering and Planning Guide 2 Observing Safety Guidelines

Handling Optical FibersWhen you work with optical fibers, take the following precautions:

• Wear safety glasses when you install optical fibers.

• Never look into an active optical fiber or an optical connector opening of an active or powered-up unit.

• Prevent direct exposure to optical fiber ends or optical connector ends where you can directly access the laser signal.

• Clean your hands after you handle optical fibers. Small pieces of glass are not always visible and contact with your eyes may be harmful.

• Do not handle pieces of optical fiber with your fingers. Use tweezers or adhesive tape to lift and discard any loose optical fiber ends.

• Wear rubber gloves when you clean optical connectors. The gloves prevent direct contact with the isopropyl alcohol and prevent contamination of the ferrules with skin oils.

• Place all optical fiber clippings in a plastic container provided for that purpose. • Handle optical fibers with caution. Place the optical fibers in a safe location during

installation. • Protect all optical fiber connectors with clean dust caps at all times.• Follow the manufacturer instructions when you use an optical test set. Incorrect

calibration or control settings can create hazardous levels of radiation.

DANGER: Risk of eye injury.Do not look directly into the optical beam. Invisible light can severely damage your eyes. Keep all optical connectors capped.

CAUTION: Risk of damage to line cards.Never connect or disconnect an optical fiber on an active or powered up optical amplifier. To connect or disconnect an optical fiber, place the optical amplifier out-of-service (OOS), unseat the optical amplifier, then connect or disconnect the optical fiber. High optical power levels can damage line cards if improper connections are made.

WARNING: If you have a piece of glass in your eye, get medical assistance immediately.

© 2001-2004 Mahi Networks, Inc. All Rights Reserved. Using Optical Fibers 2-3



Repairing Optical FibersWhen an accidental break occurs in the optical fiber, do the following:

• Report the location of the damaged optical fiber to both the central office and field repair personnel.

• Power down all laser sources to the optical fiber and disconnect the remote optical fiber end from the laser sources. See “Handling Optical Fibers” on page 2-3 before you disconnect any optical fiber from a laser source. The sources can be in a central office, on subscriber premises, or in a remote location.

Working with Power

When you install power feeds to the product input power terminals or perform routing power maintenance, do the following:

• Read and understand the power procedures you perform.• Take the necessary precautions and use the correct insulated tools to perform any tasks.• Remove or cover metal objects, such as jewelry, watches, buttons, or buckles on your body

or clothing.A tripped circuit breaker indicates that an over-current event has probably occurred. Before resetting the circuit breaker, service personnel must:

• Determine the parts of the product fed by the circuit breaker.• Determine if there are any obvious causes for the trip occurring in the affected parts and

associated wiring. • Verify that the power distribution unit element configuration complies with the installation

instructions.After you reset any previously tripped circuit breaker, wait near the product for at least one minute to ensure that the fault clears and the product returns to normal operation.

When you remove the breaker module, follow the instructions provided on the product label.

DANGER: Risk of high power current surge.

DANGER: Risk of electrical shock.Read and understand the power procedures you are performing. Take necessary precautions and use the appropriate insulated tools when working with power.

2-4 Working with Power © 2001-2004 Mahi Networks, Inc. All Rights Reserved.



Dissipating Static ElectricityThe level of static electricity increases on your body when you move around or come into contact with other charged surfaces. Excessive levels of static electricity can damage equipment. Wear a heel grounder (that attaches to your leg and foot), or an antistatic wrist-strap, or another personal grounding device, when you work on any of the following:

• network element shelves (including the metal frame and cover)• cables connected to line cards• line cards• push-buttons, switches or connectors on interface panels

Any one of the previously mentioned grounding devices dissipates electrostatic charges to the ground quickly. Use grounding devices correctly to eliminate the Electrostatic Discharge (ESD) threat you pose to the equipment.

When you wear an antistatic wrist-strap and a heel grounder, make sure the grounding straps are in contact with a moist part of your skin. The grounding cord of your wrist-strap should be connected to the grounding plug on a grounded fixture of the product you are working on. Grounded fixtures are accessible on Mahi Networks Mi7 products.

To ensure the best ESD protection:

• Check grounding straps with an appropriate test station, if available.• Install bays on conductive floor coverings.• Provide conductive shoes, antistatic wrist-straps, or heel grounders to all personnel

working on the equipment.

Preventing Line Card DamageAll line cards are subject to damage by rough handling or by electrostatic discharge. The following section shows how to prevent damage to line cards.

NOTE: If you are working in a “non-lab” environment (floor is not ESD), then it is only necessary to wear antistatic wrist-straps.

© 2001-2004 Mahi Networks, Inc. All Rights Reserved. Dissipating Static Electricity 2-5



Handling, Installing, or Replacing Line CardsWhen you handle, install, or replace line cards, take the following precautions:

• Wear an antistatic wrist-strap or another personal grounding device before you remove a line card from its package or from the shelf.

• Protect line cards that are not in active use on the shelf by storing each one separately in a shielded box.

• Handle each line card by the faceplate or stiffener.• Do not touch the solder side of the line card, the pin connector, or the components.• Do not stack line cards on or against each other.• Inspect all pin connectors on each line card for damage before use.• Inspect all line cards for damage before inserting into shelf.• Do not force line cards into their packaging material.• Do not force line cards into their positions in the shelf.• Protect all optical connectors of the transmit and receive optical line cards with clean dust

caps at all times.• Allow each line card to reach room temperature before you insert it into the shelf.

Storing Line CardsLeave spare line cards in the original shielded containers until needed. To prevent damage to stored line cards, follow standard procedures for preventing the following:

• accumulation of dirt or dust on the pin connectors• damage to the printed-circuit board or its components• warpage to printed-circuit boards stored in areas where the humidity can exceed 95% and

the temperature can exceed 70°C.

DANGER: Risk of personal injury.Weight of line cards can exceed 10 kg (25 lbs). Use caution when handling line cards, especially if you remove the line cards from a high shelf on the bay.

DANGER: Hot surfaces can cause burns. When handling these line cards, take the necessary precautions and read the specific instructions for that line card. For example, wear insulating gloves when you remove these line cards.

3 Preparation Mi7 Central Office Engineering and Planning Guide

Overview of the Mi7The basic Mi7 system consists of an X3 Fabric Shelf (X3FS), a Primary Line Card Shelf (PLCS), and a Power Distribution Unit (PDU), all of which can be installed in a single seven-foot rack. The system can optionally be expanded with an Expansion Line Card Shelf (ELCS) and a PDU in a second rack. The mounting brackets for each shelf and PDU are adaptable to both domestic and ETSI rack dimensions. Shelves can be mounted in WECO (2") or EIA (1.75") and ETSI.

An Mi7 installation requires separate redundant -48V power inputs to the PDU for each shelf in a rack. The PDU, in turn, powers each shelf.

Six fans (two fan trays with three fans each) cool each shelf. The fans are temperature controlled and vary their speed automatically. Each fan tray comes with an air filter, reducing the chance of particle intake.

Craft access is achieved with a computer connected to ports on the active Network Controller Card (NCC) on the PLCS. Management access is achieved through connectors in the Maintenance, Alarm, and Timing (MAT) panel in the upper area of the PLCS.

Optical traffic input and output is through the line cards contained in the PLCS and ELCS. The PLCS and ELCS each have sixteen slots used for line cards, and two slots for NCC cards. Line cards support 1, 4, 8, or 16 optical facilities (depending on line card type).

Shelves are interconnected with fiber optic cables and CAT-5 electrical cables, which are provided by Mahi Networks, and are connected during installation.

See “Line Card Placement Considerations” on page 3-13 for information on other cabling and wiring.

Cables, Wires, and TerminationsThis section provides general information about the cables, wires, and terminations used with the Mi7.

• Power cables from the office facility should be determined by distance and local practices, and should terminate in 3/8-inch diameter two-hole compression lugs, with centers that are one inch apart.

PDU Wire GaugesTable 1 shows maximum distance in feet provided by varying gauges of wires, installation configurations, and permissible voltage drops. For different current levels (400A, 260A, 200A, 100A, 60A, and 129A) and a typical voltage drop of 2 volts the maximum distance in feet is given for various American Wire Gauge (AWG) types. Mahi can provide a configuration tool for variations from the standard 2 volt drop and the amperage. Use this table as a conservative guideline that can be modified by local engineering practices as necessary.

Mechanical RequirementsThis section describes site requirements and preparation for an Mi7 installation.

Rack RequirementsThe Mi7 installs in a standard 23-inch telecom rack with an equipment mounting aperture that is 43RU or taller. Its mounting hardware is compatible with tapped holes at 1 inch or 1-3/4 inches vertically on centers, and 22-5/16 inches horizontally on centers.

Safety grounding for the rack must be connected to the Common Bonding Network (CBN) or the Isolated Bonding Network (IBN) per local practice.

The rack should be bolted to the floor and mounted to a super bar for stability.

Mahi Networks recommends using NEBS-approved seven-foot racks.

HardwareAll hardware needed to install the Mi7 is provided.

Line Card Placement Considerations

Line Card to Fabric Port Card ConnectionsThe PLCS and ELCS each contain 16 slots for line cards. In general, line cards can be placed in any slot in the PLCS or ELCS. The following limitations and considerations should be noted:

• There is a fixed relationship between line card slots and Fabric Port Card slots in the X3FS. Each line card in the PLCS must be connected to a specific Fabric Port Card in the X3FS based upon slot number. Line cards in PLCS slots 1-16 must be cabled to Fabric Port Cards in X3FS slots 1-16, respectively, and line cards in ELCS slots 1-16 must be cabled to Fabric Port Cards in X3FS slots 17-32, respectively. Each line card to Fabric Port Card connection requires two fiber optic cables.

• Octal OC-48 line cards can only be placed in the PLCS. Octal OC-48 line cards cannot be placed in the ELCS. All other line cards may be placed in any line card slot in the PLCS or ELCS.

• Octal OC-48 line cards must be connected to two Fabric Port Cards in the X3FS. All other line cards are connected to only one Fabric Port Card in the X3FS. The second Fabric Port Card connected to an Octal OC-48 card must be located directly below the first Fabric Port Card. For example, if an Octal OC-48 is placed in PLCS slot 2, then it must be connected to Fabric Port Cards in X3FS slots 2 and 18. Note that, in this example, no line card can be

placed in ELCS slot 2 because a line card in ELCS slot 2 would require a connection to a Fabric Port Card in X3FS slot 18. See Figure 10 and Figure 11.

Example: An Octal OC-48 line card in PLCS slot 2 must be connected to Fabric Port Cards in X3FS slots 2 and 18.

The Fabric Port Card slots are one above the other, and the lower slot is normally connected to a line card in the ELCS.

Slot Assignment Scheme with Octal OC-48 Line CardsSpecial consideration should be given to assigning line card slots in deployments that include both Octal 48 line cards and an ELCS. Octal OC-48 line cards have two special requirements: they can only be assigned to PLCS slots, and they require that the corresponding slot in the ELCS remain blank. These special requirements can cause certain assignment schemes to result in stranded (unusable) line card capacity in the Mi7.

The suggested assignment scheme is to alternate between the PLCS and ELCS when assigning line card slots. The line card slots are ordered as: PLCS slot 1, ELCS slot 1, PLCS slot 2, ELCS slot 2, and so on. Because Octal OC-48 line cards can only be placed in the PLCS, this assignment scheme may at times lead to “skipped” slots in the ELCS (an ELCS slot must be skipped if it is next in line for assignment but the card to be assigned is an Octal 48). Any skipped slots should be backfilled as new non-Octal OC-48 line cards are assigned.

Other slot assignment schemes may result in stranded capacity or the inability to install an Octal OC-48. For example, a scheme that assigns all PLCS slots prior to assignment any ELCS slots results in no suitable slots for Octal OC-48 line cards after the placement of only 16 cards.

Special RequirementsThis section describes requirements for building, environmental, electrical, timing, and space considerations.

Building RequirementsThe building housing the Mi7 installation should have a loading dock for equipment delivery, and a hand truck or forklift for moving equipment to the installation location. The building should have an elevator if the installation site is on a floor other than ground level.

Shipping PalletsThe Mi7 shelves are shipped on wooden pallets that measure about 31 inches wide, 33 inches deep, and 48 inches high. The loaded weight of the pallets is about 175 lbs (about 80 kg). All doors and elevators to the installation location must be able to accommodate the pallet size.

Cable ManagementFiber raceways, fiber trays, or cable ladder racks are recommended for cable management.

Spares StorageSpare cards for the Mi7 require special storage consideration. For dimensions of individual cards, see Appendix A, “Mi7 Specifications.”

3-16 Special Requirements © 2001-2004 Mahi Networks, Inc. All Rights Reserved.



Environmental RequirementsThe Mi7 requires an operating environment between 32° and 122° F, from -200 to 13,123 Ft. (4000 meters), 10% to 85% humidity (non-condensing), and adequate cooling to accommodate a 10,000 Watt fully configured system.

Electrical RequirementsThe Mi7 typically requires two power inputs per shelf of -48 VDC (-38 VDC to -75 VDC), which are designated A and B input facilities. In certain cases, a single pair of A and B input facilities can power two shelves located in a single rack. Each input facility must consist of two -48V cables, and two return cables. Each rack in the Mi7 installation must be separately powered.

The input facilities must be rated to supply 80 Amp or 150 Amp depending on the requirements of the specific shelves in the rack. Each PDU supplied with the Mi7 is equipped with the appropriate circuit breakers.

Timing RequirementsThe recommended timing source for the Mi7 is Building Integrated Timing Supply (BITS) or Synchronization Timing Unit (STU) (both supplied by copper wire). You can also configure the system to operate using line timing.

Space RequirementsThe Mi7 installation fits into a standard seven-foot rack. The front cover has a swing radius of 20 inches. A line card installation requires about 20 inches in front of the shelf in order to line up the line card properly with the slot.

© 2001-2004 Mahi Networks, Inc. All Rights Reserved. Special Requirements 3-17



A comfortable clearance for working on the Mi7 installation is 3.5 feet in front of the rack, and 3 feet behind the rack. Most servicing for the Mi7 is done from the front. Rear access is for X3FS maintenance only. See Figure 12 for a diagram of the space requirements.

Circuit Breaker ConfigurationsThe Power Distribution Unit (PDU) is shipped with a full complement of installed circuit breakers. The complement of circuit breakers is tailored for each specific installation, and in most cases the circuit breakers will not need to be changed. If the installation specifications are altered, call Technical Support at Mahi Networks, Inc. Figure 18 shows the front of the PDU and the circuit breaker locations.

Figure 18 Front of PDU with Circuit Breakers

The PDU supports circuit breakers with the following ratings:

• 75 Amp• 150 AmpUnused circuit breaker locations are installed with circuit breaker blanks.

The circuit breaker that supplies power to the X3FS must be rated 75 Amps. The circuit breaker in the circuit supplying power to the PLCS or the ELCS must be rated 150 Amps. Table 10 on page 4-3 shows breaker ratings for various shelf combinations.

Shelf assignments vary among installations. If shelf assignments change before the installation is completed, contact the Mahi Networks Global Support Center to order cables of adequate length.

Office Facility Power RecommendationsMahi Networks recommends installing equipment according to local practices. Rules about cable gauge and breaker/fuse sizing vary per location. The tables in this section provide recommendations only; local practices should prevail. Recommended characteristics for the office facility power are detailed in Table 12. Figures in Table 12 assume fully redundant systems: 14 XC, 2 NCC per line card shelf, and 2 FCC per X3FS.

NOTE: For this example, shelves are numbered according to their position in the rack in order to correspond with terminal connections on the PDU. The instructions in this section assume the unit in the upper-shelf rack position (the PLCS) is SHELF 1, and the unit in the lower-shelf rack position (the X3FS) is SHELF 2. Check local practice and the Network Operations Center (NOC) installation orders for shelf assignments, and designate the shelf numbers accordingly.

DANGER: This equipment contains parts at HAZARDOUS POWER LEVELS that can be directly accessed during the installation procedure. This equipment must be installed, operated, and serviced by qualified technical personnel only.

NOTE: Each input feed and input return cable can vary in size from 6 AWG to 4/0 AWG depending on the anticipated power load of the installed equipment and the distance the cable needs to travel. Insulation temperature and voltage ratings of all input feed and input return cables must follow local practice, and must terminate in a two-hole compression lug at the Mi7 end.

4-4 Office Facility Power Recommendations © 2001-2004 Mahi Networks, Inc. All Rights Reserved.



Power to each PDU is typically supplied through four input feed cables and four input return cables. Racks installed with only a single shelf may use only two input feed cables and two input return cables. Racks installed with two shelves may use only two input feed cables and two input return cables.

Wire and Cable RoutingThe X3FS, PLCS, and ELCS each have cable routing ports on the right and left side (see Figure 19). These cable routing ports are the ingress and egress points for all wiring and cabling. Route all wires and cables through the cable routing ports.

Figure 19 Cable Routing Ports

MAT LayoutsThe Maintenance, Alarm, and Timing (MAT) area of each shelf has connections for various external and intershelf wiring. The MAT layout is different for each Mi7 shelf type, as shown in Figure 20 on page 4-6.

The Important Role of Card BlanksCard blanks are essential to insuring temperature control and electromagnetic management of the Mi7. Every slot of every Mi7 shelf must be populated with either an active card or a card blank. Every type of card has an associated card blank available. A card blank is simply a card of sheet steel with a faceplate, similar in shape to the associated card. All blanks are short enough so that they do not touch the midplane or backplane when fully inserted.

The Mi7 can be populated with varying numbers of cards, depending on the requirements of the installation. Temperature control and electromagnetic management in each of the shelves is dependent on card density, so in a shelf where full population of cards is not required, a complement of blanks must also be installed.

CAUTION: Each slot in the shelf must be populated with either a card or a card blank. Deviation from this scheme may result in equipment damage.

Mi7 Central Office Engineering and Planning Guide A Mi7 Specifications

There are some differences in the functionality of the NCCs on PLCS versus those on the ELCS. Those differences are explained below.

NCC on PLCS• Each NCC carries a copy of the OS7 image.• provides control and management redundancy on the Mi7• At the time of boot up, if the standby NCC in the PLCS is different from that of the

active NCC in the PLCS, the standby NCC software will be auto-updated. The Mi7 issues notifications and posts proper conditions to indicate that these events are occurring.

• The files and database information reside on the active PLCS NCC and are transferred to the standby PLCS NCC when it boots up. The information is constantly kept in sync between the active and standby NCCs after boot-up.

NCC on ELCS• Each NCC carries a copy of the OS7 image, however the OS7 image on ELCS NCC is

not active.• provides a communication link between the PLCS and ELCS shelves and distributes

timing to the ELCS line cards• At the time of boot-up, if an NCC in the ELCS has a different revision level from that

of the active NCC in the PLCS, the firmware on the NCC in the ELCS is automatically updated to match the firmware on the NCC in the PLCS. The OSI image on the ELCS NCC is not updated.

• ELCS NCCs do not carry any files or database information.

System Facility Density

All OC modules support both SONET non-concatenated and concatenated interfaces on the same module. This functionality is software provisionable.

Optical Interface Specifications

Line Cards (SDX and MSX)Telcordia GR-253-CORE, Issue 3 governs Mi7 OC-3 through OC-192 optical interface specifications, except that the Mi7 OC-192 LR2 optical interface specifications have modified Tx and Rx power levels. Reach values are based on loss and dispersion characteristics for C-SMF. Attenuation values are stated in Telcordia specifications as 0.45 dB/km for 1310 nm sources and 0.275 dB/km for 1550 nm sources.

Dispersion values are 5.3 ps/nm-km for broad linewidth 1310 nm sources (OC-3/12/48 SR and IR1), and 3.3 ps/nm-km for narrow linewidth 1310 nm sources (OC-3/12/48 LR1 and OC-192 SR) and 20 ps/nm-km for 1550 nm sources. Note that some reach values are dispersion limited.

A “1” or no number after the reach letter designation implies a 1310 nm source. The “2” implies a 1550 nm source. OC-3/12 specifications meet Telcordia specifications for OC-12.

OC-48/STM-16 (Octal)The OC-48/STM-16 (Octal) line card have one RUN LED tri-colored (green/red/amber) status and one Loss Of Signal (LOS) LEDs on the faceplate:

• The RUN LED:– Fast flashing green indicates the card is initializing or is in self test.– Slow flashing green indicates that the card has been provisioned out of service.– Solid green indicates the line card is IS-NR or plugged in, but not provisioned.– Red indicates the card has failed its self diagnostic and needs to be replaced.– Flashing Amber indicates the card firmware is out of date, and/or is being automatically

updated.• The LOS LED is located under each set of optical line connectors. An illuminated LED

(solid amber) indicates a loss of signal on that optical circuit. If this LED is not on, then the facility is provisioned, in service, and operating normally, or it is not provisioned at all.

Figure 24 OC-48/STM-16 Octal LED Display




OC-48/STM-16, OC-192/STM-64 and OC-192/STM-64 ITU C-Band TunableThe OC-48/STM-16, OC-192/STM-64, and OC-192/STM-64 ITU C-Band Tunable line cards have one RUN LED tri-colored (green/red/amber) status and one Loss Of Signal (LOS) LEDs on the faceplate:

• The RUN LED:– Fast flashing green indicates the card is initializing or is in self test.– Slow flashing green indicates that the card has been provisioned out of service.– Solid green indicates the line card is IS-NR or plugged in, but not provisioned.– Red indicates the card has failed its self diagnostic and needs to be replaced.– Flashing Amber indicates the card firmware is out of date, and/or is being automatically

updated.• The LOS LED is located under each set of optical line connectors. An illuminated LED

(solid amber) indicates a loss of signal on that optical circuit. If this LED is not on, then the facility provisioned is in service and operating normally, or it is not provisioned at all.

GbE The GbE line cards have one RUN LED tri-colored (green/red/amber) status and one Link LEDs on the faceplate:

• The RUN LED:– Fast flashing green indicates the card is initializing or is in self test.– Slow flashing green indicates that the card has been provisioned out of service.– Solid green indicates the line card is IS-NR or plugged in, but not provisioned.– Red indicates the card has failed its self diagnostic and needs to be replaced.– Flashing Amber indicates the card’s firmware is out of date and is being automatically

updated.• The LINK LED, when illuminated (solid green) indicates that the GbE link, as defined in

IEEE 802.3, is working properly. When not lit, the link status is Fail as defined in IEEE 802.3.

Figure 26 GbE LED Display




PPXThe PPX server card has one RUN LED tri-colored (green/red/amber) status and one ACT LEDs on the faceplate:

• The RUN LED:– Flashing green indicates the card is initializing or is in self test.– Solid green indicates the line card is IS-NR or plugged in, but not provisioned.– Red indicates the card has failed its self diagnostic and needs to be replaced.– Fast flashing Amber indicates the card is in a transitional state.– Slow flashing Amber indicates the card has been manually placed out-of-service.

• The ACT LED located under the RUN LED, when illuminated, indicates that the PPX is active. If the ACT LED is not lit, the card is the standby card in the pair.

Figure 27 PPX LED Display




Network Controller Card 2The Network Controller Card (NCC2) has six card-status LEDs on the faceplate, as illustrated below.

• The RUN LED at the top of the faceplate is tri-colored (red/green/amber):– Flashing green indicates the card is initializing or is in self test.– Solid green indicates the line card has passed self test.– Red indicates the card has failed its self diagnostic and needs to be replaced.– Flashing amber indicates user intervention is required for one of the following reasons:

• The NCC detects a null System ID on the primary line card shelf. The user must enter a valid system ID.

• The NCC was not previously in this primary line card shelf and is requesting to delete its database.

• The NCC detects an invalid shelf ID in the expansion line card shelf. The user must set a correct shelf ID.

• A software mismatch condition is detected.• The ACT LED is located under the RUN LED. An illuminated ACT LED indicates this

NCC is the active controller in the active/standby NCC pair that is controlling that shelf.• The remaining four LEDs (UP A, UP B, DN A, and DN B) are directly related to the

Ethernet port and behave the same as the ACT LED. Solid green illumination of an LED indicates that a fiber is connected to another NCC. An unlit LED indicates no fiber connections to another NCC are active.

• The NCC Craft Ethernet Integrity LED (not shown) is green. Flashing green indicates data activity on the link. An unlit LED indicates the Ethernet link is down or not connected.
