SRAM BATTERY REPLACEMENT
WARNING
Do not remove the SRAM from the Solid State Drive when performing this
procedure.
The LED closest to the SRAM is a “status” LED it will illuminate RED during disk access if the battery
needs to be replaced. The second LED is a “busy” LED that indicates when the SRAM is being accessed.
If both LED’s illuminate RED during disk access the battery is not charged adequately.
1. With the SRAM
in
the Solid State Disk, use a jewelers screw-driver to remove the screw securing
the battery holder.
2. Remove the battery holder and the battery.
3. Replace the battery with a new 3V, lithium ,165 mAH, battery P/N 74-122904-00. Verify the + sign
is pointing up. Make up a label that says “SRAM Battery Replaced” and then the current date and
affix it to the back door of the electronics cabinet of the workstation.
