1 System error LED
When this yellow LED is lit, one or more LEDs elsewhere in the server might also be lit to direct you to the
source of the error. For more information, see Rear view LEDs.
2 System ID LED
The blue system ID LED helps you to visually locate the server. A system ID LED is also located on the front
of the server. Each time you press the system ID button, the state of both the system ID LEDs changes. The
LEDs can be changed to on, blinking, or off.
