Removing and Installing the DC-Input Power Supplies
Chapter 4
Removal and Replacement Procedures
Installing a 6000 W DC-Input Power Supply
Note
With the PWR-6000-DC power supply, you have the option of installing an Input Power Module (IPM)
(previously removed) with the DC-input wires and the ground wires still connected. You can then install
your power supply and insert the fully-wired IPM. Read through this procedure carefully before
installing your power supply.
Warning
Before performing any of the following procedures, ensure that power is removed from the DC
circuits. To ensure that all power is removed, locate the circuit breakers or fuses on the DC power
lines that service the DC circuits. Turn OFF the DC power line circuit breakers and remove the DC
power line fuses. Statement 322
Note
For proper 6000W DC-input redundant power configuration, all input wires (two pairs for 2800W
DC-input, three pairs for 4500W DC-input, and four pairs for 6000W DC-input) for one 6000W
DC-input power supply must come from the same battery system (A feed); all input wires (two pairs for
2800W DC-input, three pairs for 4500W DC-input, and four pairs for 6000W DC-input) for the other
6000W DC-input power supply must come from another battery system (B feed).
Note
For multiple DC input power supply, each DC input must be protected by dedicated circuit breaker or
fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local or
national electrical code requirements.
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last. Statement 1046
Note
The 6000 W DC-input power supply provides power of 2800 W, 4500 W, or 6000 W. Select 2800 W by
wiring any two positive (+)/negative (-) terminal pairs in any sequence. Select 4500 W by wiring any
three positive (+)/negative (-) terminal pairs in any sequence. Select 6000 W by wiring all four positive
(+)/negative (-) terminal pairs. The Cisco IOS software detects the wired inputs and sets the proper
system power.
Note
The 6000 W DC-input power supply ground provides the system ground connection when the
PWR-6000-DC power supply is installed in a Catalyst 6500 series chassis. Install the ground as
described in this procedure.
Note
For redundant power supplies, you must connect the 6000 W DC-input power supply ground for both
power supplies.
