Unit Identification (UID) LEDs
Blue Unit Identification (UID) LED indicators on the front and back of the server help identify
the server in large rack deployments. If you press the UID button on the front of the server, the
corresponding UID LED on the back of the server
lights to identify it as the server being
serviced.
Server Health LEDs
Three server health LED indicators are located on the front of the ProLiant ML350 G2 between
the UID button and the Power On/Standby LED. These indicate the status of the:
■
Internally serviceable components (processor, PPM, memory subsystem, temperature
control, Server Feature Board, and fans)
■
Externally serviceable components (hot-pluggable power supplies)
■
Embedded NIC
The NIC information is also represented on the rear panel with the three LEDs located above the
RJ-45 connector.
For detailed information on the system status and network controller LEDs, refer to

System Board LEDs
In addition to the system status LEDs, the ProLiant ML350 G2 now includes 11 diagnostic LEDs
on the system board. These LEDs indicate error conditions, such as processor, PPM, or memory
module failures. Refer to the graphic and table on the following pages to determine what these
lights indicate.
