Battery Replacement
Your module provides back-up power for RAM through a replaceable lithium
battery (cat. no. 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 replace battery threshold level.
To replace the lithium battery:
1. Remove power from the SLC 500 power supply module.
2. Remove the module from the chassis by pressing the retainer clips at the top
and bottom of the module.
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 while removing the
module from the chassis, they can be easily replaced. Pry off any
broken clips from the bottom with a screwdriver, if necessary. Do
not twist off. Snap in the replacement clip. Order cat. no.
1746-R15 (two 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.
