Replace a power supply unit

You can replace a power supply unit (PSU). If your switch includes a second power
module bay in which a PSU is installed, you can replace the PSU while the switch remains
powered on and functioning. The figures in the following procedure show models
M4300-24X24F and M4300-24X.
To remove one PSU and reinstall another PSU in the same power module bay:
1. If your switch functions with a single PSU only, disconnect the power cord from the
PSU and let the switch power down.
If your switch functions with two PSUs, you do not need to power down the switch
and can perform a hot swap.
2. Remove the PSU from the power module bay by moving the release latch to the left
and pulling the extraction handle.
3. Insert the other PSU into the power module bay, and gently push the PSU into the
bay until the latch locks.
