About Power Supply Indicators

Each power supply module has a set of four status indicator LEDs located on the module's front panel. The following illustration shows the location of these LEDs on power supplies in the Sun Blade 8000 Chassis. The LEDs are located in a similar position on the power supplies installed in a Sun Blade 8000 P Chassis.
