operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Installing or Replacing an AC Power Supply

Step 1 Turn off the power at its source.
Step 2 Remove the power cord from the power cord retainer.
Step 3 Remove the power cord from the power connector.
Press the release latch at the right side of the power supply module inward and slide the power supply

Do not force the power supply or fan module into a slot. This might damage the pins on the switch
if they are not aligned with the module.
A power supply that is only partially connected to the switch can disrupt the system operation.
Remove power from the power supply module before removing or installing the module.
The power supply is hot-swappable. In some configurations, such as full PoE+ or power-sharing
mode, removing a power supply causes powered devices to shut down until the power budget
matches the input power of a single power supply. To minimize network interruption, hot swap the
power supply, ensuring that the remaining supply has sufficient PoE power for all powered ports.
For information about the switch commands that display the available power budget, see the Cisco
