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. You can also use the ThinkSystem System Manager or a remote management program to change the state of the system ID LEDs to assist in visually locating the server among other servers.
