System ID LEDs
A pair of blue LEDs, one at the rear of the server, and one on the front panel, can be used to easily identify the server
when it is part of a large stack of servers. A single blue LED located at the back edge of the server board next to the
backup battery is visible through the rear panel. The two LEDs mirror each other and can be illuminated by the
Baseboard Management Controller (BMC) either by pressing a button on the chassis front panel or through server-
management software. When the button is pressed on the front panel, both LEDs illuminate and stay illuminated until
the button is pushed again. If the LED is illuminated through a remote System Identify command, the LED turns off
after a timeout period. See Figure 83 on page 6-5 for the location of the rear Main Board LED. The front panel ID
LED and the ID activation button are shown in Figure 84.
