Dell system batteries (CMOS) are very common model (CR2032) and available at most hardware stores or online retailers. Replacing CMOS in Dell servers is fairly straightforward process and the process is documented on Dell Website as well.
NOTE: As recommended in Dell documentation, please power down the server, unplug it, and wear electrostatic discharge protection to prevent any issues while working inside the appliance. |
Replacing the CMOS battery will reset some settings in BIOS. So, follow below steps to reconfigure those changes after replacing the CMOS battery.
Once the application server (Glassfish/Payara) is up after reboot, please set KC-PINs and test with pingsaka.sh script.
NOTE: The TPM might have gone into lockout mode due to inaccessibility during the battery replacement and should come out of lockout mode automatically after couple of hours. So, plan the battery replacement accordingly as the appliance might be unavailable for processing until TPM comes out of lockout mode. |
