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.

Removing a Power Supply
To remove a power supply, complete the following procedure:
1. Locate the power supply you want to remove.
2. Push the thumb latch to unlock the power supply handle and pull the
handle down to undock the supply.
CAUTION Any unused power supply slots must be covered with a
blanking plug. Uncovered slots can disrupt the air flow used
for cooling the system.
