Power Supply Module Installation
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.
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).
