Installing an AC-Power-Supply Module

This procedure is for installing an AC-power-supply module in the PSU 1 power-supply slot. Repeat these steps to install a power-supply module in the PSU 2 power-supply slot.

Note If you operate the switch with two power supplies, enter the power-supply dual global configuration command to configure the switch to send a message when one power supply is missing.

Each AC-power input is dedicated to one power-supply module (PSU 1 or PSU 2). One AC-power input does not power on both power-supply modules at the same time (Figure 3-6):

To install an AC-powered power-supply module, follow these steps:

Step 1 Verify that the power from the power source is off.

Step 2 Insert the new power-supply module in the power-supply slot, and gently push it into the slot

(see Figure 3-7). When correctly inserted, the power-supply module is flush with the switch rear panel.
