Chapter 1:

Product Overview 1-

Introduction

The XA/R 8-slot module is an entry level, fault-tolerant computer based on RISC technology.

Like its predecessors, the 8-slot module is designed so that customers can participate in

routine maintenance procedures.

The 8-slot module supports both VOS and FTX operating systems. Maintenance procedures

for VOS modules are located in the VOS Module Maintenance Guide (R343) and the FTXmaintenance procedures are in the FTX Module Maintenance Guide (R202X).

This chapter provides an overview of the 8-slot module including the:

• control panel

• processor cabinet (front and rear compartments)

• expansion cabinets

• main processor boards

• I/O adapter (IOA) chassis

• D600 peripheral subsystem

• tape drive subsystems.

The 8-slot module consists of a single 54-inch cabinet containing up to 8 main processor

boards, two D600 peripheral subsystems, an I/O adapter (IOA) chassis, and an optional

cartridge tape drive. One or two expansion cabinets may be added to contain additional

peripheral devices.

The main components of the 8-slot module operate in duplex pairs; that is, two identical

components (main processor boards, bulk power supplies) perform the exact same function

at exactly the same time. If one component fails, the other in the pair continues operating

without interruption or performance degradation. Generally, under these conditions, you can

remove and replace the failed component of a duplex pair without shutting down the module

or affecting ongoing processes.

Figure 1-1 shows a front-view illustration of the 8-slot module.

The control panel has several switches, controls, and indicators. The control panel lights and

STATUS DISPLAY window help you to detect and isolate system problems. The control

panel as it relates to VOS system maintenance, is described in the VOS Module Maintenance

Guide (R343). For FTX systems, see the FTX Module Maintenance Guide (R202X).

For a complete description of the control panel, see the VOS Module Control Panel Guide

(R126) for VOS systems and the FTX Control Panel Guide (R176X) for FTX systems.


The 8-slot processor cabinet contains the main chassis, peripherals, IOA chassis, and bulk

power supplies. Customer-replaceable components are mounted in the front and rear

compartments of the cabinet.

The front and rear cabinet doors are locked and require a key. To unlock and open the cabinet

door, turn the key 1/4-turn counterclockwise.

Front Compartment Components

The following components are located in the front compartment of the 8-slot processor

cabinet.

• T502 or T601 tape drive (optional)

• Main processor boards (CPU, Memory, IOP, and optional Link controller)

• 8-position fan module

• D600 peripheral subsystems

• Bulk power supplies

Note: The bulk power supplies are not customer-replaceable components.

The 8-slot module may also include up to two expansion cabinets. An expansion cabinet is

the same size as the processor cabinet, but does not contain main processor boards or a control

panel. Two types of expansion cabinets are available.

• Standard expansion cabinet

• IOP expansion cabinet

The standard expansion cabinet (type E100-4X) provides mounting space and two AC

controllers to power additional tape drives. The types of tape drives that are supported are

described in “Tape Drive Subsystems” later in this chapter.

The IOP expansion cabinet (type K35X-4X) provides both AC power for tape drives and DC

power for D600 peripheral subsystems.

Main Chassis Slot Numbering

The main chassis in the processor cabinet holds up to 8 main processor boards. The slots are

numbered from 24 - 31. Labels showing the board slot numbers are located to the right of the

board slots, on the inside of the main chassis door. Even-numbered board slots have white

labels and white board guides. Odd-numbered board slots have black labels and black board

guides.

All boards in the main chassis have an adjacent partner board. The partner for each

even-numbered slot is located in the odd-numbered slot directly below it. For example, the

board in slot 24 is partnered with the board in slot 25, the board in slot 26 is partnered with

the board in slot 27, and so forth down to partners in slots 30 and 31. Figure 1-6 shows slot

numbers and board partners for the 8-slot chassis.

Note: Two slots in the 8-slot chassis are keyed to accept only the VOS Link Controller.

† These boards can only be configured in a module containing a G860-10 CPU.

Each board is briefly described in the following subsections.

CPU BoardsThe minium configuration for an 8-slot module requires one duplex pair of CPU boards

located in slots 30 and 31 of the main chassis. Two CPU types are available for the 8-slot

module:

• G860-10

• G861

The G860-10 CPU is based on the Intel® i860 RISC microprocessor operating at 32 MHz.

The G861 is based on the Intel i860XP RISC microprocessor operating at 48 MHz. The G861

CPU is a uni-processor board containing one logical microprocessor.

Each CPU board contains a pair of microprocessors that perform the identical operation at

exactly the same time. If an error is detected on either board, the faulty board is taken off-line

and its partner continues processing.

IOA Chassis


Memory Boards

The minimum configuration requires one duplex pair of memory boards in slots 28 and 29 of

the main chassis. System needs affect the assignment of additional slots to memory boards.

The number of memory boards and the capacity of each board vary.

IOP BoardsOne pair of duplex IOP boards occupy slots 24 and 25 of the main chassis. One duplex pair

of IOP boards supports one 16-slot IOA chassis. The adapters for tape, disk, and

communications I/O reside in the IOA chassis.

Link Controller Boards

Two slots in the main chassis are dedicated for Link controllers. If your module is configured

to support StrataLINK™, two I101-11 Link controllers occupy slots 26 and 27 of the main

chassis.

For FTX systems, two slots are reserved for future communications product upgrades.

IOA Chassis

I/O Adapter (IOA) cards are mounted side by side inside a 16-slot IOA chassis. One IOA

chassis is installed in the rear compartment of the processor cabinet. There are 14 slots for

communications, tape, and disk IOAs; two slots for chassis terminators. The slots are

numbered right to left (0 to 15) and the terminators must be in slots 14 and 15. Cabling and

space considerations can affect IOA configurations on your module.

When an IOA card is inserted into a chassis slot, the part number label is hidden and the card

is distinguishable by one or more of the following identifiers:

•communications-type label on the locking lever of the card

• descriptive label on the front edge of the card

• color-coded connectors on the front edge of the card.

The 8-slot module is also shipped with an IOA chassis configuration chart, which can be used

as a key in identifying IOA cards. This card is the flat black magnetic strip directly to the left

of the IOA chassis. Grasp the tab marked OPEN, and pull it to the left to display the IOA

chassis configuration information.

The 8-slot module supports the IOA cards listed in Table 1-3. (Refer to Appendix A

“Customer-Replaceable Components” for IOA part numbers.)

Note: FTX modules require a duplex pair of D603 or D604 disk devices to be used as

the boot drive.

The front of each disk contains a label that identifies the device name and location. The device

name is determined by the customer and Stratus sales engineer and is filled in before the

device leaves the factory. The device location code identifies the location of the disk within

the system including the:

• cabinet in which the disk is installed (relative to the processor cabinet)• slot number of the supporting IOP board

• slot number of the supporting IOA card

• physical location within the subsystem (left, center, or right).

Tape Drive Subsystems


Tape Drive Subsystems

The 8-slot module supports the IOP-based tape drive subsystems listed in Table 1-5. Each

tape drive subsystem has a supporting I/O Adapter card which is mounted in the IOA chassis.

Note: The T502 cartridge tape drive and the T601 DAT drive are the only tape drives

that are customer replaceable.5

The T502 cartridge tape drive or the T601 DAT drive can be mounted in the processor

cabinet. The T103, T203-002, and T401 tape drives must be mounted in an expansion cabinet.

Preventive maintenance is essential to ensure reliable and continuous tape drive operation.

Stratus recommends specific cleaning instructions and frequency for each type of tape drive.

Refer to the Tape User’s Preventive Maintenance Guide (R357) for tape drive cleaning

procedures.

Chapter 2:

Electrical and Cooling System 2-

This chapter describes the electrical and cooling system for the 8-slot module. For specific

electrical requirements, refer to the Site Planning Guide (R003) for VOS systems or the FTX

Site Planning Guide (R178X) for FTX systems.

Electrical System

The major components that supply power to the 8-slot processor cabinet are:

• bulk power supplies

• battery power

• IOA chassis power.

Caution: Electrical system components in the 8-slot module are not customer-

replaceable. If it is necessary to remove or replace any of these parts, contact the

Customer Assistance Center (CAC).

Bulk Power Supplies

The 8-slot processor cabinet accepts 200/208/220/240 (+/- 10%) volts, 60/50 Hz, of AC

power and has dual power cords. The power passes from the power cords through the dualtransformers to the two bulk power supplies. The bulk power supplies are located one above

the other at the bottom of the processor cabinet.

The bulk power supplies manage the power distribution for the module. They provide 24

VDC to the back panel of the processor cabinet. The individual boards develop their

operating voltages from this power. The bulk power supplies also manage the stop and start

control, receiving signals from the control panel, and the CPU. Each power supply has a

breaker switch so that you can interrupt its output.

The top power supply, labeled ODD, distributes power to the odd board slots. The bottom

power supply, labeled EVEN, distributes power to the even board slots. This design allows the

module to continue operating if one bulk power supply should fail.

Battery Power

Battery units within the bulk power modules save memory during short power failures. This

enables processes to continue to run, without being restarted, after power is restored. The

battery pack maintains the memory contents for up to 10 - 15 minutes after a power failure

occurs, depending on the configuration of the system.

8/20/2019 XA/R Module (r346-02)

22/24

Cooling System

2-2 Chapter 2: Electrical and Cooling System

IOA Chassis Power

The IOA chassis receives its power from both bulk power modules. If one bulk power module

fails, the IOA chassis draws all of its power from the other one. The IOA cards in the chassis

develop their operating voltages from this power.

Cooling SystemAdequate air flow across boards and components in a cabinet is essential to ensure reliable

operation. The 8-slot module is designed for air to flow from left to right through the

processor cabinet and uses multiple fans to cool components during operation.

When an expansion cabinet is added to the processor cabinet, an air plenum is installed

between the cabinets to provide proper air circulation. The air plenum between cabinets

discharges warm air out the rear and draws cool air in through the front.

Most fans are not customer-replaceable with the exception of the 8-position fan module. The

8-position fan module is located in the processor cabinet next to the main chassis. (See

Figure 1-3 in Chapter 1 “Product Overview.”) The D600 disk drive fans are built into theD600 device unit. If a fan should fail, the entire device unit is replaced.

Other components, such as bulk power supplies, transformers, and IOA chassis are cooled by

fan units that must be replaced (if a failure occurs) by a Stratus customer engineer.
