System LEDs
As you install your Sun Fire V440 server, be aware of several system status LED indicators on both the front and back panels. These indicators provide general system status, alert you to system problems, and help you to determine the location of system faults.
At the top left of the server as you look at its front are three general system status LEDs. Two of these LEDs, the system Service Required LED and the System Activity LED, provide a snapshot of the overall system status. One LED, the Locator LED, helps you to locate a specific system quickly, even though it might be one of many systems in a room. The front panel Locator LED is at the far left in the cluster. The Locator LED is lit by command from the administrator. For instructions, see the Sun Fire V440 Server Diagnostics and Troubleshooting Guide.
Other LEDs located on the front of the server work in conjunction with specific fault LED icons. For example, a power supply fault illuminates the associated power supply Service Required LED and the system Service Required LED. Since all front panel status LEDs are powered by the server’s
