Q. Are Cisco Catalyst 2960-XR field-replaceable power supplies hot swappable?
A. Yes. Cisco Catalyst 2960-XR power supplies are hot swappable.
Q. Can a non-PoE Cisco Catalyst 2960-X Series Switch support PoE by replacing its power supply with a PoE-
capable power supply?
A. No. A non-PoE Cisco Catalyst 2960-X Series Switch will not support PoE by using a PoE-capable power
supply.
Q. Can we increase the PoE budget of Cisco Catalyst 2960-X Series Switch by replacing its power supply with a
high-capacity power supply?
A. The available PoE budget is fixed for a given model of Cisco Catalyst 2960-X Series Switch. Replacing the
switch power supply will not increase the PoE budget.
Q. Do I need two power supplies to run a Cisco Catalyst 2960-XR Series Switch?
A. No. The Cisco Catalyst 2960-XR Series Switches support two field-replaceable power supplies to provide
redundancy. The power supplies are in shared mode. Three power supply options are available for use in the
Cisco Catalyst 2960-XR Series, as shown in Table 6.
Table 6. Power Supply Options for Cisco Catalyst 2960-XR Series Switches
Part Numbers Description
PWR-C2-250W AC FRU power supply and fan for all non-PoE C2960-XR switches, provides 250W AC of power
PWR-C2-640W AC FRU power supply and fan for all 370W PoE+ C2960-XR switches, provides 640W AC of power
PWR-C2-1025W AC FRU power supply and fan for all 740W PoE+ C2960-XR switches, provides 1025W AC of power
Q. In Cisco Catalyst 2960-XR switches, are the power supplies in shared mode or standby mode?
A. When both the power supplies are present in Cisco Catalyst 2960-XR switches, those power supplies are in
shared mode. The power is drawn from both the power supplies.
Q. Do the Cisco Catalyst 2960-X Series Switches have external RPS support?
A. The Cisco Catalyst 2960-X LAN Base and LAN Lite models support RPS 2300. The Cisco Catalyst 2960-XR
switches do not have external RPS support. Instead, customers looking for redundant power should insert an
additional field-replaceable power supply module. For more information on RPS 2300 please refer to

Software Capabilities
Q. What software images do the Cisco Catalyst 2960-X Series Switches support?
A. All Cisco Catalyst 2960-X and 2960-XR switches use a single universal image. The tar file will be named
c2960x-universalk9-tar.150-2.EX for 2960-X and 2960-XR switches. The name will change over time as new
Cisco IOS Software releases are made available.
Q. Do Cisco Catalyst 2960-X Series Switches support signed images?
A. Yes. Cisco Catalyst 2960-X Series Switches support only signed images, which prevents any Cisco IOS
Software image tampering.
Q. How do I get the cryptography features, and is there an additional charge for them?
A. Cisco Catalyst 2960-X Series Switches will support Cisco IOS Software images with cryptography features by
default. These are the only images available. These images with cryptography features will be loaded during
manufacture. Non-K9 images will not be available for the Cisco Catalyst 2960-X Series Switches.
