Installing and Removing Power Supply Units

This section provides instructions for installing and removing the power supply units in the Cisco MDS 9148T
switch.

Installing Power Supply Units

You can replace one power supply unit (PSU) while the other one provides power to the switch.

Before you begin

• To implement n+n redundancy, each PSU must be connected to a separate power feed. Otherwise, only

one power feed is required.
