Remove a hot-swap power supply unit

Use this information to remove a power supply unit.

About this task

If the power supply unit to be removed is the only one installed, the power supply unit is not hot-swappable. Before removing it, you must turn off the server first. To support redundancy mode or hot-swap, install an additional hot-swap power supply unit.

Attention

• Read Installation Guidelines and Safety inspection checklist 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 systems.

Procedure

1. Disconnect the power cord from the hot-swap power supply unit.

   • For AC power supply units, disconnect both ends of the power cord and keep it in an ESD-safe place.

   Note

   If you are replacing two power supply units, 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 unit until the power output LED for the firstly replaced power supply unit is lit. For the location of the power output LED, refer to The LED on the power supply unit.
2. Press the release tab toward the handle and carefully pull the handle at the same time to slide the hot-swap power supply unit out of the chassis.
