Removing and Installing the DC-Input Power Supplies
Step 12
Position and secure the left and the right inner terminal block covers.
Step 13
Secure outer terminal block cover.
Step 14
If you are installing a second power supply operating at 2700 W in the right-side power supply bay,

Step 15
After 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.

power supplies.
Step 16
Turn 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.
engages a pawl that locks the power supply in the chassis.
Step 17
Verify the power supply operation by ensuring that the power supply front panel LEDs are in the
following states:
following 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

for item location and identification on the 4000 W DC-input power supply.
Note
You 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.

Step 2
Verify that power is off to the DC circuit that is connected to 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 3
Prepare the source DC-input power cables by attaching the appropriately sized lugs.
