Intrepid-HC IDU

Installing the IDU in a 19"/ETSI Rack

Warning! The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or exposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

The Intrepid-HC IDU is installed in a standard 19" ETSI rack as shown in the following illustration.


As shown in the illustration, four screws, supplied with the installation kit, are used to secure the IDU to the rack.


IDU Dimensions

The following illustration shows the dimensions (in millimeters) of the Intrepid-HC IDU.


Grounding the IDU

The following illustration shows how the IDU is grounded to the rack.

A grounding wire is connected below the IDU-RFU interface using a single screw with two washers.

IDU Grounding Notes

The IDU is suitable for installation in a Common Bonding Network (CBN).

Only copper wire should be used.

The wire must be at least 6 AWG.

Single Point Stud

Grounding Wire


Connector and connection surfaces must be plated. Bare conductors must be coated with antioxidant before crimp connections are made to the screws.

The unit provides a ground for each IDU, via a one-hole mounted lug onto a single-point stud. The stud must be installed using a UL-listed ring tongue terminal, and two star washers for anti-rotation.

For antenna ports, lightning protection is used that does not permit transients of a greater magnitude than the following:

Open Circuit: 1.2-50us 600V

Short Circuit: 8-20us 300A

The current carrying “ampacity” of the conductor connecting the IDU frame to the DC return conductor is equal to, or greater than, the ampacity of the associated DC return conductor.

Power Supply Notes

When selecting a power source, the following must be considered:

DC power can be from -40.5 VDC to -60 VDC.

Recommended: Availability of a UPS (Uninterrupted Power Source), battery backup, and emergency power generator.

Whether or not the power source provides constant power (i.e., power is secured on weekends or is shut off frequently and consistently).

The power supply must have grounding points on the AC and DC sides.

Caution!

The user power supply GND must be connected to the positive pole in the IDU power supply. Any other connection may cause damage to the system!

Power supply grounding should be in accordance with the following illustration:

Site Acceptance Checklist Notes

The following notes provide important additional information about the Site Acceptance Checklist.

1. Antenna Mounting

Mounting pole is of sufficient height to clear local obstructions, such as parapets, window cleaning gantries, and lift housings.

Mounting Pole is of sufficient height, and is safely positioned, so as not to cause a safety hazard. No person should be able to walk in front of, or look directly into the path of the microwave radio beam. Where possible, the pole should be away from the edge of the building.

Mounting pole is secure and perpendicular. A pole that is not perpendicular may cause problems during antenna alignment.


Mounting pole is grounded as per site specifications. All operators and site owners have specific requirements regarding the grounding of installations. As a minimum, typical requirements are such that any metal structure must be connected to the existing lightning protection ground of the building. Where it extends beyond the 45-degree cone of protection of existing lightning conductors, additional lightning protectors should be installed.

All steelwork is Galvanized or Stainless Steel, as appropriate to prevent corrosion.

2. Antenna

Antenna is grounded as per site specifications. See the third point in the Antenna Mounting section above.

Antenna sway braces are fitted and installed correctly, where applicable. Typically, for an antenna of 1.2 m or larger, an extra sway brace is fitted to the mounting frame of the antenna. This sway brace should not be mounted to the same pole as the antenna, but should be installed directly back to the tower or an alternative point.

Antenna Water Drain Plugs are fitted and removed, where appropriate. Some antennas have moisture drain plugs installed at various points around the antenna. The purpose of these plugs is to allow any moisture that forms on the inside of the antenna or radome to drip out and prevent a pool within the antenna. Only the plugs at the bottom of the antenna, after installation, should be removed. All other plugs should be left in position.

3. RFU (Radio Frequency Unit)

The RFU is grounded as per installation instructions. See the third point in the Antenna Mounting section above.

The RFU polarization is as per link requirements and matches the polarization of the antenna.

4. IDU (Indoor Unit)

The main traffic connections are correctly terminated and crimped as per cable and connector manufacturer instructions. All fiber optic patch leads should be routed carefully and efficiently, using conduits to prevent damage to the cables.

All other user terminations are secure and correctly terminated.

All labeling is complete as per site requirements. Labeling is specific to each customer. At a site with only one installation, labeling may be unnecessary. However, at sites with multiple installations, correct and adequate labeling is essential for future maintenance operations.

Typical labeling requirements include:

Antenna labels - for link identity and bearing

RFU labels - for link identity, frequency, and polarization

Coax cable labels - for link identity, close to the RFU, IDU, and either end of any joint

IDU labels - for link identity


1+0 Commissioning Procedure

Scope

This section describes the recommended commissioning tests for a radio link in a 1+0 configuration.

The purpose of the commissioning tests is to verify correct and proper operation of the product.

Commissioning Test

The following tests should be performed on each installed link.

Link Verification

“Radio” LED on the IDM front panel is green, indicating the radio link is up.

Received Signal Level (RSL) is up to +/- 4 dB from the expected (calculated) level at both ends of the link.

Radio Bit Error Rate (BER) is 10E-11 or higher.

If working with ATPC, ATPC is operating as expected (RSL = reference level).

After connecting test equipment or end equipment to the line interfaces, all LEDs on the front panel of the IDM are green.

Line Interfaces Test

50/100/200 Mbps, GbE Interface - connect a Packet Analyzer to the Fast Ethernet interface and verify error-free operation (no packet loss) for at least 1 hour. Use a physical loop at the far end.

2 Mbps/1.5 Mbps - connect PDH test equipment to the E1/T1 interface and verify error-free operation for at least 1 hour. Use a physical or software loop at the far end.

Interoperability Verification

Connect customer end equipment to the line interfaces, and verify correct operation.

Further interoperability tests should be performed in accordance with the specific requirements of the connected end equipment.


Management Verification

Launch the element management software on the PC.

Verify that you can manage the link and that you are able to perform changes to the link configuration (frequency channel, Tx power, system name, time & date, etc.).

Verify that the management application reports the correct parameters when performing the above.

Verify that there are no active alarms on the link.

If the management station is located at a remote site (Network Operation Center), verify that the management station can manage the link and receive traps.

Loopback Operation

Perform line loopback, IDU loopback, RFU loopback, and Remote loopback, and verify that the system operates accordingly.

1+1 Commissioning Procedure

Scope

This section describes the recommended commissioning tests for a radio link in 1+1 HSB (Hot Standby) and SD (Space Diversity) or FD (Frequency Diversity) configurations (internal protection).

The purpose of the commissioning tests is to verify correct and proper operation of the product.

Note that in this section:

Primary refers to the RFUs connected to the main path of the directional coupler in a 1+1 HSB configuration.

Secondary refers to the RFUs connected to the secondary path of the directional coupler in a 1+1 HSB configuration.

Commissioning Tests

The following tests should be performed on each installed link.

Link Verification

The following steps should be repeated for each of the four RFU combinations (Primary-Primary, Primary-Secondary, Secondary-Primary, Secondary-Secondary).

Line Interfaces Test

50/100/200 Mbps, GbE interface - connect a Packet Analyzer to the Fast Ethernet interfaces using an FE splitter, and verify error-free operation (no packet loss) for at least 1 hour. Use a physical loop at the far end.

2 Mbps/1.5 Mbps - connect PDH test equipment to the E1/T1 interfaces using splitters, and verify error-free operation for at least 1 hour. Use a physical loop between the splitters at the far end.

Switching Tests

Define each of the N channels as preferred (one at a time) for errorless switching to the +1 channel. The regular channel supports hitless switching to the +1 channel.

50/100/200 Mbps, GbE Interface

Connect a Packet Analyzer to the Fast Ethernet interfaces using splitters. Use a physical loop between the splitters at the far end. Verify no alarms exist.

Perform the following switching tests from one IDM to the other, and verify the system switches automatically.

- Power: power off the active IDM

- Radio: disconnect the coax cable of the active IDM

- Management: force a switch using the management software

1.5/2 Mbps Interface

Connect PDH test equipment to the interfaces using splitters. Use a physical loop between the splitters at the far end. Verify no alarms exist.

Perform the following switching tests from one IDM to the other, and verify the system switches automatically.

- Power: power off the active IDM

- Radio: disconnect the coax cable of the active IDM

- Management: force a switch using the management application

Interoperability Verification

Connect the customer end equipment to the line interfaces and verify correct operation.

Further interoperability tests should be performed in accordance with the specific requirements of the connected end equipment.


Management Verification

Launch the management application.

Verify that you can manage the link and that you are able to perform changes to the link configuration (frequency channel, TX power, system name, time & date, etc.).

Verify that the application reports the correct parameters when performing the above.

Verify that there are no active alarms on the link.

If the management station is located a t a remote site (Network Operation Center), verify that the management station can manage the link and receive traps.

Commissioning Log

The Commissioning Log is an integral part of the commissioning procedure and should be filled in for each installed link.

The Commissioning Log gathers all relevant information regarding the installed link and contains a checklist of all recommended commissioning tests.

Maintaining the Commissioning Log is important for tracking your installations, and to provide essential data for wireless Networks.

Upon completing the Commissioning Log, send the log to GE MDS support center at [email protected].
