3.3 Module Replacement

When you replace the Processor module in a singleĆProcessor rack,

you will need to reĆload the operating system and all application

tasks unless the new Processor already has the operating system

loaded on it and the contents of RAM are valid. In this case, you will

need to load the application tasks only.

In a multipleĆProcessor rack, if your replacement Processor does not

already have an operating system and valid RAM, you will have to

reĆload the operating system and all application tasks to all

Processors in the rack. If the new Processor has an operating

system, you need only load the application tasks that you want to run

on that particular Processor.

Use the following procedure to replace a Processor module:

Step 1. Turn off power to the system. All power to the rack, as well

as all power to the wiring leading to the module, should be

off.

Step 2. Use a screwdriver to loosen the screws holding the

RSĆ232C connectors to the Processor. Detach the

connectors from the module.

Step 3. Loosen the screws that hold the module in the rack.

Remove the module from the slot in the rack.

Step 4. Place the module in the antiĆstatic bag it came in, being

careful not to touch the connectors on the back of the

module. Place the module and the antiĆstatic bag in the

cardboard shipping container.

Step 5. Take the new module out of the antiĆstatic bag, being

careful not to touch the connectors on the back of the

module.

Step 6. Activate the battery by taking it out of its holder and

removing the tape that covers it. Replace the battery in its

holder. Make certain that the battery is facing in the proper

direction, i.e., the end marked +" on the battery is facing

the end marked +" on the battery holder.

Step 7. Insert the module into the correct slot in the rack. Use a

screwdriver to secure the module into the slot.

Step 8. Attach the RSĆ232C cable connector(s) to the mating half

on the module. Make certain that the connector is the

proper one for this module. Use a screwdriver to secure

the connector to the module.

Step 9. Turn on power to the system. The module will

automatically execute its powerĆup diagnostics. At the

completion of its diagnostics, the seven segment LEDs on

the faceplate should display LO" if this is the only

Processor module in the rack or the leftmost Processor in

a multiĆProcessor configuration and there is no operating

system on the Processor. The LEDs on all other Processor

modules should be blank. The green OK" light should be

lit, and the BAT. OK" should be lit if the tape was removed

from the battery.

Step 10. Load the operating system using the directions in 4.1.
