5U84 enclosure fault LEDs
Visually inspect the front panel area for fault LEDs, then locate the component fault LEDs, based on general
location identified on the operator's panel or the drawer indicators. If a hardware issue prevents access to the
DSMU or CLI, this is the only option available. An asterisk (*) indicates a fault condition.
Operator's panel fault LEDs
The operator's (ops) panel uses several green and amber LEDs to identify various states. Use the amber fault
conditions identified on the operator's (ops) panel to direct you to the fault LEDs on suspect modules. The
asterisk (*) indicates a fault condition.
