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
• Installation Guidelines
• Installing an AC-Power Supply
• Installing a DC-Power Supply (Only Catalyst 3750-E and 3560-E Switches)
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).
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. Statement 206

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
