  Removing and Installing the DC-Input Power Supplies
Step 14From the left side of the power supply, connect the third pair of source DC cables to the power supply 
terminal block VE-3 (see Figure 1-37) in this order:
1.Negative (-) source DC cable to terminal posts –VE-3
2.Positive (+) source DC cable to terminal posts +VE-3
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).

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
CautionTo prevent a short circuit or shock hazard after wiring the DC-input power supply, reinstall the terminal 
block covers.
Step 20After you confirm that all installation steps are completed correctly, remove any safety flags, lockout 
devices, or adhesive tape from the source DC circuit breakers, and energize the input circuits to the 
power supplies. 
Step 21Turn 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 22Verify the power supply operation by ensuring that the power supply front panel LEDs are in the 
following states:
INPUT OK 1 LED—If you have source DC cables attached to the VE-1 pair of power supply inputs, 
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC 
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage 
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
INPUT OK 2 LED—If you have source DC cables attached to the VE-2 pair of power supply inputs, 
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC 
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage 
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing. 
INPUT OK 3 LED—If you have source DC cables attached to the VE-3 pair of power supply inputs, 
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC 
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage 
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing. 
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.
Installing the 4000 W Power Supply (Wiring for 4000 W Operation; Right Power Bay)
See 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 you are 
using.
NoteFor proper 4000 W DC-input 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).

Chapter 1      Removal and Replacement Procedures
  Removing and Installing the DC-Input Power Supplies
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 4000 W operation in the right power bay 
(POWER 2), 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 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 3Prepare the source DC-input 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 1-38.) 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.
Figure 1-38 DC Power Cable Lug
CautionUse both hands to install and remove power supplies. Each DC-input power supply weighs 32 pounds 
(14.5 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 1-39.)

Tighten the power supply captive installation screws 
Step 6Remove the two screws that secure the outer terminal block cover Lift the cover up to detach the cover 
tabs from the slots in the power supply. Set the cover and the screws aside
Step 7Remove the two screws that secure the left inner terminal block cover. Lift up on the cover to detach the 
cover tab from the slot in the power supply. Set the cover and the screws aside.
Step 8Remove the one screw that secures the right inner terminal block cover. Lift up on the cover to detach 
the cover tab from the slot in the power supply. Set the cover and the screw aside.
Step 9Remove the two plastic insulators from the plastic bag that shipped with the power supply. Position the 
larger plastic insulator (eight holes) over terminal block VE-1/VE-2. Align the holes in plastic with the 
terminal block posts. The end flap on the insulator should face away from the DC source cable entry 
direction. 
Step 10Position the smaller plastic insulator (four holes) over the four-post terminal block VE-3. Align the holes 
in the plastic with the terminal block posts. The end flap on the insulator should face away from the 
source DC cable entry direction.
Step 11Fold the end flaps down on both insulators to cover the open side of the terminal block (opposite side 
from cable entry). 
Step 12From the right side of the power supply, connect the power supply ground cable and the source DC cables 
to the DC-input wires to the terminal block (see Figure 1-40) in this order:
1.Ground cable lug to the ground terminal posts
2.Negative (–) source DC cables to terminal posts –VE-1 and –VE-2
3.Positive (+) source DC cables to terminal posts +VE-1 and +VE-2
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).
