This document covers installing and removing the AC-input power supply in the Catalyst 4500-X series switch chassis.
Note AC-input power supplies are not included as part of the basic chassis configuration product numbers. The AC-input power supplies are ordered separately.
Contents
This installation note contains the following sections
There are two versions of the 750 W AC-input power supply, the C4KX-PWR-750AC-F power supply which has back-to-front airflow (the release lever is color-coded blue indicating cool side) and the C4KX-PWR-750AC-R power supply which has front-to-back airflow (the release lever is color-coded burgundy indicating warm side). Both power supplies provide 750 W of power. Figure 1 shows the AC-input power supply and identifies the major features.

Tools Required
No specific tools are required to install or remove the AC-input power supply.
Installing the Power Supply
To install the AC-input power supply, follow these steps:
Step 1 Remove the power supply from the shipping packaging and discard the packaging.
Step 2 Verify that the new power supply has the correct airflow direction (front-to-back or back-to-front) for your situation. The power supply release lever (see Figure 1), is color-coded blue for back-to-front airflow or burgundy for front-to-back airflow.
Note The chassis determines which airflow direction is correct by polling all of the fan assemblies and the power supplies. The airflow direction for all of the devices must be the same. If the airflow direction of the replacement power supply or the redundant power supply does not match the fan assemblies airflow direction, the system software shuts down the power supply and generates a power supply mismatch error message on the console.
Step 3 If the chassis power supply bay is empty, proceed to Step 4. If you are replacing a power supply already installed in the chassis power supply bay, go to the “Removing the Power Supply” section. If the chassis power supply bay is empty, but has a power supply blank cover installed, you must remove the blank cover (see Figure 2):
a. Grasp the two retaining clips with your thumb and forefinger and squeeze to release the blank cover from the power supply bay.
b. While still squeezing the two clips, pull on them to remove the blank cover from the power supply bay.
Figure 2 Power Supply Blank Cover
Note If the redundant power supply bay on the Catalyst 4500-X chassis is unused, you must cover it with a power supply blank cover (part no. C4KX-PWR-BLANK=) to maintain proper airflow through the chassis.
Step 4 Using two hands to support the new power supply, position it in front of the power supply bay and slide it into the bay.
Step 5 Firmly push on the power supply handle to fully seat the power supply in the bay. (See Figure 3.)
Note The retaining clip will pivot in and then snap into place when the power supply is fully installed in the bay. You can hear a click as the power supply release lever snaps into place.
Figure 3 Installing the AC-Input Power Supply
Step 6 Verify that you have the correct source AC power cord for your installation. See the “Power Cords” section for a list, including descriptions and illustrations, of the AC power cords supported on the power supply.
Step 7 Attach the AC power cord’s appliance connector to the AC-in receptacle on the power supply and secure the power cord in place with the velcro retaining strap on the power supply. Connect the power cord’s AC plug to the source AC outlet.
Note If the source AC outlet is live, the power supply will immediately power up. There is no power switch on the AC-input power supply.
Step 8 Verify that the power supply powers up correctly by visually monitoring the two LEDs on the power supply. (See Figure 1.) See Table 1 for a list of LED conditions and meanings.
Removing the Power Supply
To remove the AC-input power supply from the chassis, follow these steps:
Step 1 Release the AC power cord from the velcro restraint strap.
Step 2 Disconnect the AC power cord from the power supply.
Note The AC-input power supply does not have an on/off switch. Disconnecting the AC power cord immediately powers down the AC power supply.
Step 3 Grasp the power supply handle with your forefinger and place your thumb on the power supply release handle.
Step 4 Squeeze your forefinger and thumb together and pull on the power supply handle to release the power supply from the chassis bay. (See Figure 4.)
Figure 4 Removing the AC-Input Power Supply
Step 5 Slide the power supply out of the chassis bay.
Note The power supply is approximately 14 inches (35.56 cm) long. Place your other hand underneath of the power supply to support the power supply as you extract it from the chassis.
Step 6 Set the removed power supply aside.
Step 7 If you are not going to replace the power supply, place a power supply blank cover (part no. C4KX-PWR-BLANK=) over the empty power supply bay opening and snap it into place. If you are going to install a new power supply in the chassis, see the “Installing the Power Supply” section for instructions.
Power Supply Specifications
Table 2 lists and describes the electrical specifications for the 750 W AC-input power supply.
Table 2 Electrical Specifications, 750 W AC-Input Power Supply
Specification
Description
AC-input type
Autoranging input with power factor correction (PFC)
AC-input voltage
100 to 240 VAC (115/230 VAC nominal) single-phase
AC-input current
11 A @ 100 VAC (max)
6 A @ 200 VAC (max)
AC-input frequency
47 to 63 Hz (50/60 Hz nominal)
Branch circuit requirement
Each chassis power supply should have its own dedicated, fused-branch circuit:
For North America—15 A
For International—Circuits should be sized to local and national codes
All AC power supply inputs are fully isolated.
Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B.
