E LED Codes
A failure on the HP Server Remote Management Card is indicated by a flashing
signal pattern displayed by the red diagnostic LED visible below the RS-232 port
(refer to Figure F-1). The other set of LEDs located next to the LAN port indicate
LAN connection activity.
NOTE In the event that more than one error is affecting card
operation, the HP Server Remote Management Card reports
only the first failure discovered.

Each failure is stored as a four-digit code. This allows each code up to 10
"sub-codes" that can be interpreted by the diagnostic utility.
