Appendix - Fault Isolation
If the amber cabinet fault LED (at the very top of the cabinet-- front and rear) is illuminated, a CRU within the
cabinet has produced an error condition. [Both cabinet fault lights (one front and one rear) are lit when one or
more components within the cabinet has failed. ]
If the amber PCI fault status LED is lit, there is an error within the PCI card cage. The PCI Fault status LED is
located on the front of the cabinet, at the bottom of the disk shelves.
There are a number of red or green disk shelf LEDs in the disk shelf (rear), these are explained in section A.2.2.X
A.2. System Component LEDs
The following label, found on the cabinet, shows possible states for component LEDs and describes their meanings.
