NOTICE: The power-supply modules are hot-pluggable. Remove and replace only one power-supply module at a time in a system that is turned on. Leave a failed power-supply module installed in the chassis until you are ready to replace it. Operating the system with a power-supply module removed for extended periods of time can cause the system to overheat.

NOTE: The 2100-W power supply modules require 170-264 V to operate. If they are plugged into 110-V electrical outlets, the power supply modules do not power up.

1Locate the faulty power supply module.

The power supply's fault indicator is amber if AC power is available. See Figure 1-6.

If no indicators are lit, ensure that AC power is available from the electrical outlet and that the power cable is properly connected to the power supply module.

2Install a new power supply. See "Installing a Power Supply Module" on page 59.

NOTE: After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is working properly. The power supply DC power indicator turns green if the power supply is functioning properly. See Figure 1-6.

3If the problem is not resolved, see "Getting Help" on page 127. for information about obtaining technical assistance.
