Enclosure Status LEDs
At the top left of the system as you look at its front are three enclosure status LEDs.
The System Activity LED and the system Service Required LED provide a snapshot
of the overall enclosure status. The Locator LED helps you to quickly locate a
specific system even though it may be one of numerous systems in a room. The
Locator LED is at the far left in the cluster, and is lit by command from the
administrator.
