Replacing a 1400-watt or 900-watt hot-swap power supply

Use this information to replace a 1400-watt or 900-watt hot-swap power supply.

The following notes describe the type of power supply that the server supports and other information that you must consider when you install a power supply:

• The server comes standard with one 1400-watt (input voltage 110 or 220 V ac auto-sensing) hot-swap power supply or an optional 900-watt (input voltage 110 or 220 V ac auto-sensing) hot-swap power supply depending on your model.
  Note

  You cannot mix 110 V ac and 220 V ac input voltage power supplies in the server, it is not supported.
• Do not mix 900 watt and 1400 watt power supplies in the server, it is not supported.
• These power supplies are designed for parallel operation. In the event of a power-supply failure, the redundant power supply continues to power the system. The server supports a maximum of two power supplies.
  Note

  When two 900 watt or 1400 watt power supplies are installed and connected to 110 V power source, redundancy is available only for a limited configuration.
• The optional Power Interposer for Redundant Power Option kit or the Microprocessor and Memory Expansion Tray must be installed in the server to support two power supplies, if one is not installed in your model.

Statement 5

CAUTION

The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Statement 8

CAUTION

Never remove the cover on a power supply or any part that has the following label attached.

Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

To install a hot-swap power supply, complete the following steps:

1. Read the safety information and installation guidelines, see Safety and Installation guidelines.
2. Touch the static-protective package that contains the hot-swap power supply to any unpainted metal surface on the server; then, remove the power supply from the package and place it on a static-protective surface.
3. If you are installing a hot-swap power supply into an empty bay, remove the power-supply filler panel from the power-supply bay.

   

4. Replacing a 1400-watt hot-swap power supply.
   1. Grasp the handle on the rear of the power supply and slide the power supply forward into the power-supply bay until it clicks into place

      

   2. Make sure that the power supply connects firmly into the power-supply connector.
   3. Go to step 6.
5. Replacing a 900-watt hot-swap power supply.
   1. Facing the rear of the server, insert the power supply spacer against the wall on the left side of the power supply bay, if you removed it.

      

   2. Slide the power supply spacer into the bay until it snaps into place on the tabs that are on the side of the bay.
   3. Grasp the handle on the rear of the power supply and slide the power supply forward into the power-supply bay until it clicks. Make sure that the power supply connects firmly into the power-supply connector.
6. Route the power cord through the hook-and-loop strap so that it does not accidentally become disconnected.
7. Connect the power cord for the new power supply to the power-cord connector on the power supply.
8. Connect the other end of the power cord to a properly grounded electrical outlet.
9. Turn on the peripheral devices and the server.
10. Make sure that the ac power LED and the dc power LED on the power supply are lit, indicating that power is being supplied to the power supply through the power cord. During normal operation, both ac and dc power LEDs are lit. For other combinations of LEDs, see Power-supply LEDs.
