System ID LED (blue)
Use this blue system ID LED 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 on the front panel, 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.
