The rear-panel power supply status LEDs are located as shown in Figure 2-4.
FIGURE 2-4 Location of Rear-Panel Power Supply Status LEDs
The rear-panel power supply status LED has the states indicated in Table 2-8.
Note – If redundant power supplies are used in the Sun StorEdge 5310 NAS, the
power supply LEDs have the following meaning:
Both LEDs off = no power to power supplies or both power supplies bad.
Both LEDs blinking green = power supplies receiving AC power, but server is off.
Both LEDs solid green = server is fully powered on and power supplies are good.
One LED solid green and one LED amber = AC power missing from one of the
power supplies.
