Connecting Power to the Switch

This section provides instructions on connecting source power to the chassis. Two procedures are provided:

•Connecting AC Source Power to the Switch, page 3-12

•Connecting DC Source Power to the Switch, page 3-13

Note The Catalyst 4948E switch supports mixing AC-input and DC-input power supplies in the same chassis.

Connecting AC Source Power to the Switch

To connect source AC power to either a Catalyst 4948E or Catalyst 4948E-F switch, follow these steps:

Step 1 Verify that all of the site power and grounding requirements described in Chapter 2, “Preparing for Installation” have been met and the chassis is properly grounded as described in the “System Grounding” section on page 2-7.

Step 2 Verify that the power supply is fully seated in the chassis power supply bay and that the captive installation screw on the power supply is tight. Verify that the AC power switch on the power supply is off.

Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Step 3 Remove the AC power cords from the accessory kit and verify that you have the correct ones for your locale. If you are unsure as to the type of AC power cord required for your location, refer to the “300 W AC-Input Power Supply Power Cords” section on page A-8for a list of the AC power cords supported by the AC-input power supplies and consult with your local electrician.

Step 4 Plug the AC power cord’s appliance connector (IEC60320/C15) into the power supply AC-in receptacle. Figure 3-5shows plug locations for both the PWR-C49E-300AC-R and the PWR-C49E-300AC-F power supplies.

Note If you are using the optional Panduit Modular ToR Switch Inlet Duct kit (Model CDE2) with the Catalyst 4948E-F switch chassis, you need to thread the AC power cord through the air duct. Refer to the installation note supplied with the duct kit for instructions on how to do this.
