WS-CDC-2500W Cisco Catalyst 6500 2500 W DC-Input Power Supply

The WS-CDC-2500W is the Cisco 2500 W DC-input power supply for Catalyst 6500 series switches, the DC counterpart of the AC-input WS-CAC-2500W. Input is -48 VDC nominal (-40.5 to -56 VDC) in North America or -60 VDC nominal (-55 to -72 VDC) internationally, with an input current of 70 A at -48 VDC or 55 A at -60 VDC. Output is 2500 W maximum from -48 to -60 VDC.

The DC outputs are 15 A at +3.3 VDC, 5 A at +5 VDC, 10 A at +12 VDC and 55.5 A at +42 VDC, with a 4 ms output holdup time and heat dissipation of about 11,377 BTU/hour. The DC input terminal block accepts 2 to 14 AWG copper conductors, and on this 2500 W unit the terminals are labeled -, + and ground from top to bottom.

Catalyst 6500 switches that take the 2500 W supplies are the 6506, 6506-E, 6509, 6509-E, 6509-NEB, 6509-NEB-A, 6509-V-E, 6513 and 6513-E, and the 6513-E takes the DC-input unit only. Chassis pages in the store include WS-C6506-E Catalyst 6506-E chassis, WS-C6509-E Catalyst 6509-E chassis and WS-C6513-E Catalyst 6513-E chassis.

AC-input and DC-input supplies can be mixed in one chassis, and two 2500 W supplies are not fully redundant in a fully populated Catalyst 6513. Three status LEDs report INPUT OK, FAN OK and OUTPUT FAIL, and INPUT OK is green at -40.5 VDC or more. Other chassis parts are in Cisco miscellaneous parts.
