Chapter 3 Power Supply and Fan Module Installation
Installing an AC-Power Supply
Installing an AC-Power Supply
To remove and install an AC-powered power-supply module, follow these steps:
Step 1 Turn off the power at its source. For Catalyst 3560E-12D and 3560E-12SD switches, also turn off the power supply on/off switch.
Step 2 If used, detach the power cord retainer assembly from the power cord.
Step 3 Remove the power cord from the power connector.
Step 4 For 24- and 48-port switches, use a Phillips screwdriver to loosen the two captive screws at the lower edge that secure the power supply to the switch chassis (Figure 3-1).
For Catalyst 3560E-12D and 3560E-12SD switches, use a Phillips screwdriver to loosen the captive screw at the left edge of the power supply (Figure 3-2).
Caution Do not leave the power-supply slot open for more than 90 seconds while the switch is operating.
Step 5 Remove the power-supply module from the power slot by pulling on the extraction handle.
Step 6 Insert the new power supply into the power-supply slot, and gently push it into the slot (Figure 3-1and Figure 3-2). When correctly inserted, the power supply is flush with the switch rear panel. The 1150-W power-supply module extends 3.6 inches (9.14 cm) from the switch rear panel.

Step 7 For 24- and 48 port switches, align the two captive screws with the screw holes. Using a ratcheting torque screwdriver, torque each screw to 7 lbf-in. (112 ozf-in.).
