Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY 规格指南

Branch circuit requirement (AC-input)

Each chassis power supply should have its own 
dedicated, fused-branch circuit:

For North America—30 A

For International—Circuits should be sized 
according to local and national codes

All AC power supply inputs are fully isolated.

Source AC can be out of phase between 
multiple power supplies in the same chassis, 
which means that PS1 can be operating from 
phase A and PS2 can be operating from 
phase B.

Source AC can be out of phase between AC 
inputs on power supplies that are equipped 
with multiple AC inputs, which means that 
power cord 1 can be plugged into phase A and 
power cord 2 can be plugged into phase B.

DC-input voltage

–48 VDC nominal @ 37 A in North America 
(operating range: –40.5 VDC to –56 VDC)

–60 VDC nominal @ 29 A for International 
(operating range: –55 VDC to –72 VDC)

The 4000 W DC-input power supply requires 
two source DC-inputs to be connected; it 
cannot operate with only one positive 
(+)/negative (-) source DC terminal pair 
installed.

DC-input current

40 A per each DC input (three inputs)

Power supply output capacity 

4000 W with three inputs active

2700 W with two inputs active

The 4000 W power supply cannot operate with 
only one source DC-input connected.

kVA rating

5.4  kVA maximum

System power dissipation (DC power supply) 5200 W (total input power)
