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.
FIGURE 7-1 Front-Panel Power and Fault LEDs
■ 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.
