Battery Replacement
Your module provides back-up power for RAM through a replaceable lithium
battery (catalog number 1747-BA). This battery provides back-up for
approximately five years. A BAT LOW indicator on the front of the module alerts
you when the battery voltage has fallen below the the replace battery threshold
level.
To replace the lithium battery follow these steps:
1. Remove power from the SLC 500 power supply module.
2. Remove the module from the chassis by depressing the retainer clips at both
the top and bottom of the module and slide it out.
ATTENTION
Do not remove the module from the SLC 500 chassis until all
power is removed from the SLC 500 power supply.
IMPORTANT
If the top or bottom retainer clips are broken when removing the
module they can be easily replaced. Pry the broken clip(s) off
from the bottom with a screwdriver, if necessary. Do not twist
off. Snap in the replacement clip. Order Catalog Number
1746-R15 (2 per package).
ATTENTION
Do not expose the module to surfaces or other areas that may
typically hold an electrostatic charge. Electrostatic charges can
alter or destroy memory.
