PWR-4000-DC is the 4000 W DC-input power supply for Cisco Catalyst 6500 series switches. It works in the Catalyst 6506, 6506-E, 6509, 6509-E, 6509-NEB, 6509-NEB-A, 6509-V-E, 6513 and 6513-E chassis, and it shares the form factor of the 1000 W, 1300 W, 2500 W and 3000 W supplies.
Input is -48 VDC at 37 A for a nominal -48 V battery backup system (operating range -40.5 to -56 VDC) or -60 VDC at 29 A for a nominal -60 V system (operating range -55 to -72 VDC). The supply has three DC inputs, each rated 40 A and each protected by its own circuit breaker or fuse, and the terminal block accepts 4 AWG copper conductors.
Output capacity is 4000 W with three inputs active and 2700 W with two inputs active. It cannot run with only one positive and negative source terminal pair connected. Outputs are 15 A at +3.3 VDC, 5 A at +5 VDC, 12 A at +12 VDC and 90.63 A at +42 VDC with three inputs (59.68 A with two). Holdup time is 8 ms, heat dissipation is approximately 17,730 BTU/hour, the kVA rating is 5.4 kVA maximum and the weight is 30.8 lb (14.0 kg).
The INPUT OK LED turns green when the DC source is -40.5 VDC or greater and goes off below -33 VDC, and the FAN OK LED turns green while the supply fan is working.
