Determining Power Supply Status
When the amber power supply failure LED on the front of the chassis turns on,
determine which power supply is defective by checking the three status LEDs on
each supply. Each power supply has three LEDs that both indicate whether power
is supplied to the power supply and the health of the power supply. The LEDs are
ordered top to bottom on each power supply. Table 3-1 illustrates the states
indicated by the three LEDs.
