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 “Front IO assembly” on page 27.
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.
