See section 5.2 for a list of the possible reasons that the BAT. OK"

light on the Processor faceplate can shut off. If you need to replace

the battery, the superĆcapacitor will provide a typical 10 hours of

backĆup power between the time the BAT. OK" light goes off and

power is removed from the rack, and the time you insert and activate

the new battery. If you replace the battery within this time limit, you

will not need to reĆload the operating system and application tasks.

Complete battery specifications can be found in Appendix A.

Use the following procedure to replace the battery on the 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

connectors to the module. Remove 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, being careful

not to touch the connectors on the back of the module.

Step 4. Take the old battery out of the holder. Remove the tape

from the new battery and insert it in the holder. Make

certain that the battery is facing the proper direction.

Step 5. ReĆinsert the module into the correct slot in the rack. Use a

screwdriver to secure the module into the slot.

Step 6. ReĆattach the 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 7. Turn on power to the rack. The module will automatically

execute its powerĆup diagnostics. The green OK" light

should be lit, and the BAT. OK" should be lit. If this

Processor or any Processor in the rack displays code

LO", you will need to reĆload the operating system. See
