Chapter 3 Installing Fans and Power Supplies

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.
