Memory board LEDs and components
Error indicators remain illuminated when the system is powered off so that the status of the LEDs can still
be seen. This matches the behavior of all the other error indicators in the server.
Error indicators will only be cleared if:
• The locking switch is locked after the board is reinstalled
• The system has been rebooted
• The board is removed from the system
CAUTION: When the memory board locking switch is unlocked in a mode that does not support hot-add or
hot-replace capabilities, audio alarms and visual alerts occur. Removing the memory board at this point
causes server failure.
• To end the audio alarms and visual alerts, move the memory board locking switch back to the locked
position. This action does not result in data corruption or server failure.
• If removal of a single memory board is required and it is the only memory board, power down the
server and make the necessary memory changes.
