Netfinity 5500 M10 - System Board LEDs and System Board SCSI LEDs

Applicable to: World-Wide

System Board LEDs
The system board contains three SCSI LEDs and a processor LED that are turned on when the system detects an error.

Notes
1. To locate the LEDs on the system board see "System Board Component Locations".
2. Check the system error log for additional information before replacing a FRU.

System Board SCSI LEDs
A solid on or blinking system board SCSI LED indicated an error was detected. (The blinks are followed by a pause.)

Notes
1. To locate the LEDs on the system board see "System Board Component Locations".
2. If you are instructed to flash the ServeRAID controller on the system board, refer to the ServerGuide that
was shipped with the system for instructions on creating a bootable ServeRAID Flash diskette. Or refer to the WEB,
see "Online Support".
3. Check the system error log for additional information before replacing a FRU.
