SBB LED Status Indicators
The hot-swap backplane monitors shelf status to identify error conditions
or failures. This status is displayed on the SBB LEDs. The left LED dis-
plays the device activity status and the right LED displays the fault status.
•
The left LED (green) is the activity status LED and is on or flashing
when the SBB is active.
CAUTION:
For non-RAID servers, removing a SBB when
the left LED is on or flashing can cause the loss or corrup-
tion of data.
•
For RAID servers, the right LED (amber) is the SBB fault LED and
indicates an error condition when it is either on or flashing.
