Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
Installing a 6000 W DC-Input Power Supply
NoteWith 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.
WarningBefore 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
NoteFor 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).
NoteFor 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.
WarningWhen installing or replacing the unit, the ground connection must always be made first and 
disconnected last. Statement 1046
NoteThe 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.
NoteThe 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.
NoteFor redundant power supplies, you must connect the 6000 W DC-input power supply ground for both 
power supplies.

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
NoteYou should allow a minimum of 2.5 to 3 inches (63.5 mm to 76.2 mm) of space between the side of the 
power supply and any obstructions (such as the side of an enclosed equipment rack). This space is needed 
to install and secure the DC-input power cables correctly. Incorrectly routing the DC-input power cables 
can cause airflow blockage into the power supply and inadequate strain relief in the cables. The exact 
amount of space required depends upon the gauge and flexibility of the DC-input power cables you are 
using.
To install a 6000 W DC-input power supply, follow these steps:
Step 1Verify that power is off to the DC circuit that is connected to the power supply you are installing. Place 
appropriate safety flag and lockout devices at power switch handle to avoid any circuit inputs from 
becoming energized.
CautionUse both hands to install and remove power supplies. Each 6000 W DC-input power supply weighs 
35 pounds (16 kg). 
Step 2Grasp the power supply handle with one hand, and place your other hand underneath the power supply. 
Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the 
bay (Figure 1-46).
Figure 1-46 Handling a DC-Input Power Supply 
Step 3
Tighten the power supply captive installation screw (see Figure 1-47).

(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. If you are going to install an 
IPM with DC-input wires and ground wires still connected, skip steps 4 through 12 and go 
directly to step 13. 1Terminal block cover6Captive installation screw

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
Step 4Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power 
supply (Figure 1-47).
Step 5Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according 
to local and national installation requirements. Use only copper wire.
Note6000 W power supplies ship with AWG #4 lugs with 45-degree angled, 2-hole compression lug 
for both power and ground wiring. Additional lugs for different wire size should be purchased 
separately.
NoteThe power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts 
are centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you 
use an appropriately sized industry standard 45 degree angled, 2-hole, standard barrel 
compression lug for both power and ground lugs (for example, on AWG #4 wires, Panduit part 
number LCC4-14AWH-L or equivalent). The power supply ground studs, located beside the 
terminal block.
NoteFor 6000 W power supplies, use fine-stranded copper conductors rated for 90-degrees Celsius 
for North American installations. 
NoteThe 6000 W DC-input power supply provides voltages 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 terminals. The Cisco IOS software detects the wired inputs and sets 
the proper system power. 
NoteIf you are wiring for 2800 W for a single power supply, proceed to Step 7; if you are wiring 
2800 W for a redundant power supply, proceed to Step 7 and then Step 10. In either case, proceed 
to step 14 upon completion.
NoteIf you are wiring for 4500 W for a single power supply, proceed to Step 8; if you are wiring 
4500 W for a redundant power supply, proceed to Step 8 and then Step 11. In either case, proceed 
to step 14 upon completion.
NoteIf you are wiring for 6000 W for a single power supply, proceed to Step 9; if you are wiring 
6000 W for a redundant power supply, proceed to Step 9 and then Step 12. In either case, proceed 
to step 14 upon completion.
