Remove a hot-swap power supply unit
Use this information to remove a power supply unit.
About this task
Redundancy mode and hot-swap functions are supported when two power supply units are installed. For
some server models, there’s only one power supply unit and before removing it, you must turn off the server
first.
Attention:
• Read “Installation Guidelines” on page 27 to ensure that you work safely.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
Procedure
Step 1. If the server is in a rack, adjust the cable management arm (CMA) to gain access to the power
supply bay.
Step 2. Disconnect both ends of the power cord and keep it in an ESD-safe place.
Note: If you are replacing two power supplies, replace them one by one to ensure that the power
supply to the server is not interrupted. Do not disconnect the power cord from the secondly
replaced power supply until the power output LED for the firstly replaced power supply is lit. For the
location of the power output LED, refer to “Server rear view LEDs” on page 18.
Step 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.

After you finish
1. Install a new power supply or install the power-supply filler to cover the power supply bay. See “Install a
hot-swap power supply unit” on page 55.
