Removing and Installing a 1300 W or 2500 W DC-Input Power Supply
Required Tools
This section covers the power supply removal and installation procedures for the 1300 W and the
2500 W DC-input power supplies and is divided into the following topics:
• Required Tools, page 4-19
• Removing a 1300 W or 2500 W DC-Input Power Supply, page 4-19
• Installing a 1300 W or 2500 W DC-Input Power Supply, page 4-24
Use a flat-blade or number 2 Phillips-head screwdriver to perform these procedures. You might also need
cutters to cut any cable ties that are installed on the power supply.
Removing a 1300 W or 2500 W DC-Input Power Supply
Warning
Before 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
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing. Statement 1034
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last. Statement 1046
To remove a DC-input power supply, follow these steps:
Step 1
Step 2
Step 3
Verify that power is off to the DC circuit on 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.
Turn the power switch to the off (0) position on the power supply that you are removing. Turning the
power switch off also disengages a pawl that unlocks the power supply from the chassis.
See Figure 4-11 for the 1300 W DC power supply or Figure 4-12 for the 2500 W DC power supply.
Remove the two screws securing the terminal block cover, and slide the cover off the terminal block.
See Figure 4-11 for the 1300 W DC power supply or Figure 4-12 for the 2500 W DC power supply.
