Determine Current System State
To determine the current system state of an rp54xx server, first note the state of all LED indicators on the
front panel. Processing this information using the decoders provided can greatly reduce the amount of time
required to repair a suspected system fault.
The following procedure lists the tools available to aid you in determining the current system state.
Step 1.
Determine if you can get a system prompt and if so, what kind of prompt.
Step 2.
Decode the Run/Attention/Fault LED States.
Step 3.
Decode the PCI I/O LED States.
Step 4.
Decode the Fan, Power Supply, and Disk LED States.
Step 5.
Decode the GSP LED States.
Step 6.
Decode the LAN/SCSI LED States.
