Remove a Power Supply

This procedure can be performed by a customer while the server is running.

Caution

Caution  -  This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause server components to fail. When you unpack the replacement part, open the package on a grounded antistatic mat. Always use an antistatic wrist strap for hardware replacements.

Caution

Caution  -  If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.

  1. Determine which power supply requires service.

    See Identify Faulted Components and Power Supply LEDs.

  2. Locate the power supply that you want to remove.

    See CMIOU Chassis Front Components and Switch Chassis Front Components (SPARC M7-16) for the locations of the power supplies in the server.

  3. Take the necessary ESD precautions.

    See Prevent ESD Damage.
