Chapter 4 Removal and Replacement Procedures
Using the cable tie provided, place the cable tie through the slot at the top of the left terminal block cover,
Step 12
and secure the wiring that connects to the right terminal block.
Secure the outer block cover.
Step 13
Position and secure the left and right inner terminal block covers.
Step 14
Secure the outer terminal block cover.
Step 15
If you are installing a second power supply that operates at 4000 W in the right side power supply bay,

devices, or adhesive tape from the source DC circuit breakers, and energize the input circuits to the
power supplies.
Step 18 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.
Step 19 Verify the power supply operation by ensuring that the power supply front panel LEDs are in the
following states:
•
•
•
If the LEDs indicate a power problem, see the

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
Note
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.
Follow these steps to install a 4000 W DC-input power supply wired for 4000 W operation and installed
in the right power bay (POWER 2):
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection installation
instructions, see the
Verify that power is off to the DC circuit that is connected to the power supply that you are installing.
Step 2
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.
