1. For full 15.4-W support on a 48-port PoE switch, you must use the 1150-W AC power supply module in the switch.

2. If only one power supply module is installed in the RPS 2300, you must install the blank insert in the empty power supply

The 750-W and 265-W AC power supply modules are autoranging units that support input voltages
between 100 and 240 VAC. The 1150-W power supply module is an autoranging unit that supports input
voltages between 115 and 240 VAC. The DC power supply module has dual input feeds (A and B) and
supports input voltages between 36 and 72 VDC.

The AC power supply modules include a power cord for connection to an AC power outlet. The 1150-W
and 750-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord.
The DC power supply module requires wiring to a DC-power source.

Power Supply Module Installation

This section describes how to remove and install a new or replacement power supply module in
Catalyst 3750-E and Catalyst 3560-E switches, or an RPS 2300. See these sections:

• Tools and Equipment, page 5

• Installation Guidelines, page 5

• Installing an AC-Power Supply, page 6

• Installing a DC-Power Supply (Only Catalyst 3750-E and 3560-E Switches), page 8

Tools and Equipment

Obtain these necessary tools and equipment:

• Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches

(lbf-in.) or 240 ounce-force inches (ozf-in.) of pressure. For 1150-W power supply modules, the
screwdriver shaft length should be at least 6-inches long.

• Power-supply power-cord retainer in the switch accessory kit.

Power Supply Module Installation

Installation Guidelines

Observe these guidelines when removing or installing a power supply module:

• Do not force the power supply module into the slot. This can damage the pins on the switch or the

RPS 2300 if they are not aligned with the unit.

• A power supply module that is only partially connected to the switch or the RPS 2300 can disrupt

the system operation.

• Remove power from the power supply module before removing or installing the module.

• The switch supports hot swapping of the power supply when the switch is connected to an RPS 2300

that can provide backup power. You can remove and replace the power supply without interrupting
normal switch operation. When you insert a new power supply in the switch, there is a 5-second
delay while the switch software polls the device. The switch power supply then automatically
provides power, and the RPS is available to power other devices.

• The RPS 2300 supports hot swapping of the power supply module when an external device is

connected to it.

–

If the RPS 2300 is not backing up an external device, you can remove and replace the power
supply module without disconnecting the system power.

–

If two 1150-W power supply modules are installed in the RPS 2300, you can remove one of the
modules when backing up an external device.

–

The RPS 2300 does not support hot swapping of the power supply module when two 750-W
power supply modules are installed and the RPS 2300 is backing up a device with an 1150-W
power supply.

• Make sure that you tighten the power supply module captive screws before moving the switch or the

RPS 2300.

• When replacing the 1150-W or the 750-W power supply module, verify that you are using the

correct power cord (CAB-16AWG-AC, only North America).

Power Supply Module Installation

Warning

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

Warning

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

Statement 1030

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

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.

Step 2 Detach the power cord retainer from the power cord.

Step 3 Remove the power cord from the power connector.

Step 4 Use a Phillips screwdriver to loosen the two captive screws at the lower edge that secure the power

supply to the chassis.

Statement 206

Caution Do not leave the power supply slot open for more than 90 seconds while the switch or the RPS 2300 is

operational.

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 4 and

Figure 5). When correctly inserted, the power supply is flush with the panel. Note: the 1150-W power

supply module extends 3.6 inches (9.14 cm) from the panel.
