Identifying problems using status LEDs
If the System Error light in the operator information panel on the front of the
server is on, one or more LEDs inside the server may be on. Use the Light Path
Diagnostics feature to identify the type of error that occurred. See “Diagnostic tools
overview” on page 11.
You can use the Light Path Diagnostics feature built into your server to quickly
identify the type of system error that occurred. Your server is designed so that any
LEDs that are illuminated remain illuminated when the server shuts down as long
as the ac power source is good and the power supplies can 5 V dc current
to the server. This feature helps you isolate the problem if an error causes the
server to shut down. See “Diagnostic tools overview” on page 11.
