Removing and Installing the DC-Input Power Supplies
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 you are
using.
To install a 6000 W DC-input power supply, follow these steps:
Step 1
Verify that power is off to the DC circuit that is connected to the power supply you are installing. Place
appropriate safety flag and lockout devices at power switch handle to avoid any circuit inputs from
becoming energized.
Caution
Step 2
Use both hands to install and remove power supplies. Each 6000 W DC-input power supply weighs
35 pounds (16 kg).
Grasp 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 (Figure 4-46).
