Step 6
Determine whether you will be routing the source DC cables on the left- or right-side of the power 
supply. Loosen and remove the two screws securing the top half of the fixed cable guide on the side you 
will be routing the source DC cables. Remove the top half of the cable guide and set it and the screws 
aside.
Step 7Attach the appropriate size and type of lugs to the source DC cables and the ground cable. 
The maximum width of a lug is 0.300 inch (7.6 mm). The source DC cables and the ground cable must 
be sized according to local and national installation requirements. Use only copper wire. The power 
supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are centered 
0.63 inches (15.88 mm) apart and have a 1/4-20 thread. We recommend that you use an appropriately 
sized industry standard 2-hole, standard barrel compression lug. The power supply ground posts also 
have 1/4-20 threads and require two 1/4-inch split-ring washers and two 1/4-20 hex nuts (one for each 
post). 
NoteFor 2700 W power supplies, use fine-stranded copper conductors that are rated for 90°C Celsius 
for North American installations.
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.

  Removing and Installing the DC-Input Power Supplies
Step 8Connect the source DC cable lugs to the 2700 W power supply terminal block posts (Figure 1-23) in this 
order:
Ground cable lug to the ground terminal posts
Negative (–) source DC cable lug to terminal post –VE-1
Positive (+) source DC cable lug to terminal post +VE-1
NoteIf you are only going to install one pair of source DC cables (1350 W operation), you can attach 
the source DC cables to either the VE-1 or VE-2 pair of terminal posts. Also notice that there is 
only one ground connection on the power supply faceplate.
CautionWhen you tighten the terminal nuts, make sure that they are snug. Do not overtighten them. 
Overtightening the terminal nuts can damage the terminal block. The recommended torque values for 
tightening the terminal nuts are 15 inch-pounds (1.7 newton-meters) (minimum) and 20 inch-pounds 
(2.2 newton-meters) (maximum).
Figure 1-23 Attaching the Source DC Cables and the Ground Cable
Position the source DC cables in the fixed cable guide. Place the top half of the fixed cable guide over 
the source DC cables and secure the top half of the cable guide to the bottom half with two screws. 
Figure 1-24 shows how the source DC cables are routed from the left side of the power supply.
WarningWhen installing the unit, always make the ground connection first and disconnect it last. Statement 42
Step 9Route and secure the ground cable to the fixed cable guide loops with the two cable-ties supplied with 
the power supply. (See Figure 1-24.)
Step 10Position the clear plastic terminal block cover over the terminal block and secure it to the power supply 
using the four supplied screws. (See Figure 1-24.)

Removing and Installing a 4000 W DC-Input Power Supply
This section covers the power supply removal and installation procedures for the 4000 W DC-input 
power supply and is divided into the following topics:
Required Tools, page 1-37
Removing a 4000 W DC-Input Power Supply, page 1-38
Installing a 4000 W DC-Input Power Supply, page 1-40
NoteFor proper 4000 W DC-input redundant power configurations, all of the source DC for one 4000 W 
DC-input power supply must come from the same battery system (A feed); all of the source DC for the 
other 4000 W DC-input power supply must come from another battery system (B feed).
The 4000 W DC-input power supply can operate at either 2700 W or at 4000 W. 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 posts on the power supply terminal block. If you want to operate the power supply at 4000 W, you 
need to connect a third pair of source DC cables to the VE-3 terminal block posts.
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 1-26 shows the features on a 4000 W DC-input power supply. Use the illustration for reference 
as you remove and install the power supply.

  Removing and Installing the DC-Input Power Supplies
Removing a 4000 W DC-Input Power Supply
WarningWhen installing the unit, always make the ground connection first and disconnect it last. Statement 42
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 
WarningVoltage is present on the backplane when the system is operating. To reduce risk of an electric shock, 
keep hands and fingers out of the power supply bays and backplane areas. Statement 166
To remove a 4000 W DC-input power supply, follow these steps:
Step 1Verify that power is off to the DC circuit that feeds power to the power supply that you are removing. 
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 2Turn the power switch to the off (0) position on the power supply that you are removing. (See 
Figure 1-26.) 
Turning off the power switch also disengages a pawl that unlocks the power supply from the chassis.
NoteFigure 1-26 shows the PWR-4000-DC power supply with an outer terminal block cover. An earlier 
version of this power supply does not have an outer terminal block cover. To order a retrofit kit 
containing this cover, use Cisco Systems part number CVR-4000DC-TERM=.
Step 3Remove the two screws securing the outer terminal block cover. Lift the cover up to detach the two tabs 
from the slots on the power supply. Remove the cover and set it aside along with the screws. (See 
Figure 1-26.)
Step 4Remove the two screws securing the left inner terminal block cover (covering the VE-1/VE-2 terminal 
block). Lift up on the cover to detach the tab from the slot on the power supply. Remove the cover and 
set it aside along with the screws. 
Step 5Remove the one screw securing the right inner terminal block cover (covering the VE-3 terminal block). 
Lift up on the cover to detach the tab from the slot on the power supply. Remove the cover and set it aside 
along with the screw.
Step 6Disconnect the source DC cables from the terminal blocks in this order:
1.Positive (+) source DC cables from the +VE-1, +VE-2, and +VE-3 terminal posts
2.Negative (–) source DC cables from the –VE-1, –VE-2, and –VE-3 terminal posts
3.Ground cable from the ground terminal posts
You must remove all DC-input wiring from both terminal blocks before physically removing the power 
supply chassis.

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
When installing a 4000 W DC-input power supply, observe the following guidelines:
For proper 4000 W DC-input redundant power configuration, all source DC cables for one 4000 W 
DC-input power supply must come from the same battery system (A feed), and all source DC cables 
for the second 4000 W DC-input power supply must come from a different 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.
The 4000 W DC-input power supply is designed to operate at either 2700 W or 4000 W. To operate 
the power supply at 2700 W, you can wire any two positive (+) negative (–) terminal pairs (VE-1 
and VE-2, VE-2 and VE-3, or VE-1 and VE-3). To operate the power supply at 4000 W, you must 
wire all three terminal pairs.
NoteThe 4000 W DC-input power supply does not operate with only one pair of source DC cables 
connected.
For a single 4000 W DC-input power supply installation, install the power supply in the left-side 
power bay (POWER 1).
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
WarningPower supply captive installation screws must be tight to ensure protective grounding continuity. 
Statement 289
Refer to Figure 1-26 for a front view of the power supply with the major features called out.
NoteFigure 1-26 shows the PWR-4000-DC power supply with an outer terminal block cover. An earlier 
version of this power supply does not have an outer terminal block cover. To order a retrofit kit 
containing this cover, use Cisco Systems part number CVR-4000DC-TERM=.

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
Installing the 4000 W Power Supply (Wiring for 2700 W Operation; Left Power Bay)
Refer to Figure 1-26 for item location and identification on the 4000 W DC-input power supply.
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 that you 
are using.
NoteFor proper 2700 W redundant power configurations, source DC for one 4000 W DC-input power supply 
must come from the same battery system (A feed); source DC for the other 4000 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 a 4000 W DC-input power supply and wire it for 2700 W operation in the left power bay 
(POWER 1), 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 2Remove the power supply from its shipping container and remove any packaging.
Step 3Verify 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 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 4Prepare the source DC power cables by attaching the appropriately sized lugs. 
The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are 
centered 0.63 inches (15.88 mm) apart and have a 1/4-20 thread. We recommend that you use an 
appropriately sized industry standard 2-hole, standard barrel compression lug. (See Figure 1-29.) The 
power supply ground posts, located below the terminal block, also have 1/4-20 threads and require two 
1/4-inch split-ring washers and two 1/4-20 hex nuts. 
The DC-input wires and the DC power supply ground wires should be sized according to the local and 
national installation requirements. Use only copper wire. For North American installations, use 
90°C-rated, fine-strand copper conductors.
