Interpreting the Front- and Back-Panel LEDs

The Sun Fire V100 server contains two front panel LEDs (see FIGURE 7-1) and four rear panel LEDs (see FIGURE 7-2). Those on the front panel indicate power and faults only. Those on the back panel indicate the presence of up to two ethernet connections, and replicate the power and fault information of the front LEDs.

Front-Panel LEDs

The front panel LEDs are located at the top left of the servers front bezel.

Power LED (Green)

This LED is lit when the server is powered on. It is unlit when the server is in standby mode.

Fault LED (Amber)

The Fault LED is constantly on when a problem has occurred that is not fatal to the server, but that you should fix as soon as possible. Circumstances that can create this condition include the following:

The temperature inside the server’s enclosure is higher than normal.

The voltage on one of the server’s output supply rails is unusually high.

The system configuration card, containing the server’s serial number, MAC address, and NVRAM settings, has been removed.
