5 System ID button with system ID LED
Use this system ID button and the blue system ID LED to visually locate the server. A system ID LED is also
located on the rear 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. You can also use the Lenovo XClarity
Controller or a remote management program to change the state of the system ID LEDs to assist in visually
locating the server among other servers.
If the XClarity Controller USB connector is set to have both the USB 2.0 function and XClarity Controller
management function, you can press the system ID button for three seconds to switch between the two
functions.
6 System error LED
The system error LED provides basic diagnostic functions for your server. If the system error LED is lit, one or
more LEDs elsewhere in the server might also be lit to direct you to the source of the error.
