Replace a power supply unit (PSU)

Edit online

The process involves removing the existing module and inserting a new one.

Removing a PSU

Important: Before you remove a PSU, make sure that you have a replacement module to insert.
  1. Identify the PSU to be removed by using appropriate fault reporting software.
  2. As shown in the following two figures, push the red release latch to the right and hold it (1), then pull out the module by its handle (2).

Important: The PSU module bay must not be empty for more than 2 minutes while the enclosure is powered.

Inserting a PSU

  1. Rotate the PSU so that the red release latch and handle are on the left side.
  2. Slide the PSU into its slot until the latch clicks home. The enclosure automatically detects the new unit.
