Removing a hot-swap power supply

When you remove a power supply, observe the following precautions.

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.

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 remove a hot-swap power supply, do the following:

Attention

This type of power supply is hot-swap only when two power supplies are installed for redundancy. If only one power supply is installed, you must turn off the server first before removing the power supply.

1. If the server is in a rack, pull back the cable management arm to gain access to the rear of the server and the power supply.
2. Disconnect the power cord from the hot-swap power supply.
3. Press the release tab toward the handle and carefully pull the handle at the same time to slide the hot-swap power supply out of the chassis.
