Chapter 4 Power Supply Installation

Installing or Replacing an AC Power Supply

Warning Do not reach into a vacant slot or chassis while you install or remove a module. Exposed circuitry could constitute an energy hazard. Statement 206

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Warning If a Cisco external power system is not connected to the switch, install the provided connector cover on the back of the switch. Statement 386

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.

Step 4 Press the release latch at the right side of the power supply module inward and slide the power supply out. (Figure 4-6).

Caution Do not leave the power-supply slot open for more than 90 seconds while the switch is operating.

Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028

Step 5 Insert the new power supply into the power-supply slot, and gently push it into the slot (Figure 4-6). When correctly inserted, the 350-W and 715-W power supplies (excluding the power cord retainer) are flush with the switch rear panel. The 1100-W power-supply module extends 1.5 inches from the switch rear panel.
