Question 1

What is the official Cisco part number for the Catalyst 2960-XR power supply?

Accepted Answer

The approved power-supply module for Catalyst 2960-XR switches is PWR-C2-640WAC=, delivering up to 640W AC input at 100–240VAC.

Question 2

Are Catalyst 2960-XR power supplies hot-swappable?

Accepted Answer

Yes. Catalyst 2960-XR power supplies support hot-swap replacement when a redundant power system is configured.

Question 3

Can I configure redundant power for Catalyst 2960-XR switches?

Accepted Answer

Yes. You can connect an external Cisco RPS 2300 or install dual PWR-C2-640WAC= modules for power redundancy.

Question 4

What is the maximum power output of the Catalyst 2960-XR PSU?

Accepted Answer

Each PWR-C2-640WAC= module delivers up to 640W continuous output to the switch.

Question 5

What input voltage range does the Catalyst 2960-XR power supply support?

Accepted Answer

It accepts 100–240VAC at 50–60 Hz for global operation without voltage switching.

Question 6

How do I install or replace the power supply in a Catalyst 2960-XR?

Accepted Answer

Power down the switch, unplug the AC cord, slide out the old module from the rear slot, insert the new PWR-C2-640WAC= until it clicks, then reconnect power.

Question 7

What do the LED indicators on the Catalyst 2960-XR power supply mean?

Accepted Answer

A solid green LED indicates normal operation; amber denotes failure or insufficient input; off means no AC input.

Question 8

How can I troubleshoot a faulty Catalyst 2960-XR power supply?

Accepted Answer

Check the PSU LED, verify AC input, inspect system logs via CLI (show log), reseat the module, and test with a known-good unit.

Question 9

Are Catalyst 2960-XR power supplies backward compatible with older 2960-X models?

Accepted Answer

Yes. The PWR-C2-640WAC= module is compatible with both 2960-XR and legacy 2960-X series switches.

Question 10

What is the average power consumption of a Catalyst 2960-XR under normal load?

Accepted Answer

Typical non-PoE operation consumes about 50–100W; with full PoE load, consumption can approach 300W.

Question 11

Does the Catalyst 2960-XR support external redundant power supplies?

Accepted Answer

Yes. It works with the Cisco RPS 2300 for external redundancy when a single internal PSU is in use.

Question 12

What safety and regulatory certifications do Catalyst 2960-XR power supplies carry?

Accepted Answer

They are UL60950-1, CE, FCC Class A, C-Tick, and RoHS compliant for global safety and EMC standards.

Question 13

Can I use a third-party power supply with the Catalyst 2960-XR?

Accepted Answer

Cisco strongly recommends only genuine PWR-C2-640WAC= modules to ensure full compatibility and warranty coverage.

Question 14

What is the operating temperature range for Catalyst 2960-XR power supplies?

Accepted Answer

They operate reliably between 0°C and 40°C ambient temperature with proper ventilation.

Question 15

How long is the warranty on Cisco Catalyst 2960-XR power supplies?

Accepted Answer

Cisco provides a one-year limited hardware warranty on all Catalyst 2960-XR power-supply modules.

Question 16

Where can I purchase genuine Catalyst 2960-XR power supplies?

Accepted Answer

Purchase directly from Cisco or through authorized Cisco partners and distributors to ensure authenticity.
