Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
Installing a 1300 W or 2500 W DC-Input 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
WarningWhen installing or replacing the unit, the ground connection must always be made first and 
disconnected last. Statement 1046
To install a DC-input power supply, follow these steps:
Step 1Ensure that the system (earth) ground connection has been made. For ground connection installation 
instructions, see the “Establishing the System Ground” section on page 1-52.
Step 2Verify that power is off to the DC circuit on the power supply that you are installing. As an added 
precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or 
place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration 
while you are working on the circuit.
Step 3Verify that the power switch is in the off (0) position on the power supply that you are installing. 
See Figure 1-11 for the 1300 W DC power supply or Figure 1-12 for the 2500 W DC power supply.
CautionUse both hands to install and remove power supplies. Each Catalyst 6500 series DC-input power supply 
weighs between 22 pounds (10 kg) and 28 pounds (12.7 kg). 
Step 4Grasp 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. (See Figure 1-15.)
Step 5Tighten the power supply captive installation screw. (See Figure 1-11 for the 1300 W DC power supply 
or Figure 1-12 for the 2500 W DC power supply.)
Step 6Remove the two screws securing the terminal block cover, and slide the cover off of the terminal block. 
See Figure 1-11 for the 1300 W DC power supply or Figure 1-12 for the 2500 W DC power supply.

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
Step 7Attach the appropriate lugs to the DC-input wires. The maximum width of a lug is 0.300 inch (7.6 mm). 
NoteThe wire should be sized according to local and national installation requirements and electrical 
codes. Use only copper wire. For North American installations of 2500 WDC-input power 
supplies, use fine-stranded copper conductors rated for 90°C.
Step 8Attach the source DC cables to the terminal block (see Figure 1-16 for the 1300 W DC power supply or 
Figure 1-17 for the 2500 W DC power supply) in this order:
1.Source ground cable to the power supply terminal block ground post
2.Source DC negative (–) cable to the power supply terminal block negative (–) post
3.Source DC positive (+) cable to the power supply terminal block positive (+) post
NoteThe terminals on the 1300 W DC power supply DC power cable terminal block are labeled (from 
top to bottom) +, –, ground. The terminals on the 2500 W DC power supply DC power cable 
terminal block are labeled (from top to bottom) –, +, ground.
Step 9After ensuring that all wire connections are secure, reinstall the terminal block cover.
CautionTo prevent a short circuit or shock hazard after wiring the DC-input power supply, you must reinstall the 
terminal block cover.
CautionIn a system with dual power supplies, connect each power supply to a separate power source. In case of 
a power source failure to one supply, the second power source should still be available.
Step 10Remove any safety flag and lockout devices or any tape from the circuit breaker switch handle, and 
restore power by moving the circuit breaker switch handle to the on (|) position.
Step 11Turn the power switch to the on (|) position on the power supply. Turning on the power switch also 
engages a pawl that locks the power supply in the chassis.
Step 12Verify the power supply operation by ensuring that the power supply front panel LEDs are in these states:
INPUT OK LED is green
FAN OK LED is green
OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section on page A-3.

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
Removing and Installing the 2700 W DC-Input Power Supply
This section covers the power supply removal and installation procedures for the 2700 W DC-input 
power supply on the Catalyst 6504-E chassis and is divided into the following topics:
Required Tools, page 1-28
Removing a 2700 W DC-Input Power Supply, page 1-29
Installing a 2700 W DC-Input Power Supply, page 1-32
The 2700 W DC-input power supply can operate at either 1350 W or at 2700 W. If you want to operate 
the power supply at 1350 W, you only need to connect one pair of source DC cables to either the VE-1 
or the VE-2 pair of posts on the power supply terminal block. If you want to operate the power supply 
at 2700 W, you need to connect two pairs of source DC cables to the VE-1 and the VE-2 pairs of posts 
on the power supply terminal block.
NoteFor proper 2700 W DC-input redundant power configurations, all of the source DC for one 2700 W 
DC-input power supply must come from the same battery system (A feed); all of the source DC for the 
other 2700 W DC-input power supply must come from another battery system (B feed).
NoteFor multiple DC-input power supplies, each DC input must be protected by a dedicated circuit breaker 
or a fuse. The circuit breaker or fuse must be sized according to the power supply input rating and the 
local or national electrical code requirements.
Figure 1-18 shows a 2700 W DC-input power supply (p/n PWR-2700-DC/4) cabled for 2700 W 
operation with the installation components identified. 
NoteThis illustration shows the source DC cables and the ground cable routed into the power supply from the 
right side. Two pairs of source DC cables are shown indicating that the power supply is operating at 
2700 W. The source DC cables and the ground cable can also be routed out of the left-side of the power 
supply, if necessary.
Use this illustration as a reference for identifying components when removing or installing the power 
supply.

  Removing and Installing the DC-Input Power Supplies
Installing a 2700 W DC-Input Power Supply
This section provides the procedures for installing a 2700 W DC-input power supply in the 
Catalyst 6504-E switch chassis. The 2700 W DC-input power supply can operate at either 1350 W or at 
2700 W. If you want to operate the power supply at 1350 W you only need to connect one pair of source 
DC cables to either the VE-1 or the VE-2 lugs on the power supply terminal block. If you want to operate 
the power supply at 2700 W, you need to connect two pairs of source DC cables to the VE-1 and the 
VE-2 lugs on the power supply terminal block.
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 2700 W DC-input redundant power configurations, all of the source DC for one 2700 W 
DC-input power supply must come from the same battery system (A feed); all of the source DC for the 
other 2700 W DC-input power supply must come from another battery system (B feed).
NoteFor multiple DC-input power supplies, each DC input must be protected by a dedicated circuit breaker 
or a fuse. The circuit breaker or fuse must be sized according to the power supply input rating and the 
local or national electrical code requirements.
To install the 2700 W DC-input power supply in the Catalyst 6504-E chassis and cable it to source DC, 
follow these steps:
Step 1Ensure that the system (earth) ground connection has been made. For system ground connection 
installation instructions, see the “Establishing the System Ground” section on page 1-52.
Step 2Remove the power supply from its shipping container and remove any packaging material.
Step 3Locate the plastic bags that accompanied the power supply and set them aside. One bag contains one 
source DC cable guide, terminal block cover (plastic) with four screws, and two cable ties. The other 
plastic bag contains the 1/4-20 nuts and lock-washers for the terminal posts. You will use these items 
later in the procedure.
Step 4Verify that source DC power is off to the DC circuit that feeds the power supply that you are installing. 
As an added precaution, place the appropriate safety flag and lockout devices at the source DC circuit 
breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power 
restoration while you are working on the circuit.
Step 5Grasp both power supply handles, as shown in Figure 1-22. Slide the power supply into the power supply 
bay. Make sure that the power supply is fully seated in the bay. Tighten the four captive installation 
screws.
WarningPower supply captive installation screws must be tight to ensure protective grounding continuity.
