Removing and Installing the DC-Input Power Supplies Chapter 4 Removal and Replacement Procedures Removing a 950 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 Follow these steps to remove a DC-input power supply: Step 1 Identify which PEM is connected to the power supply you are removing (PEM 1 or PEM 2). Verify that the source power is off to the circuit that is connected to that PEM. (Figure 4-8 shows the location of the DC-input PEMs on the Catalyst 6503 switch chassis.) Note The system (NEBS) ground serves as the primary safety ground for the Catalyst 6503 and Catalyst 6503-E chassis that are equipped with DC-input power supplies. The DC-input power supplies for these chassis do not have a separate ground. Make sure that the chassis you are working on has the system (NEBS) ground installed. Step 2 Step 3 Step 4 Loosen the captive installation screws on the power supply. (See Figure 4-9.) Grasp the power supply handle with one hand, and slide the power supply part of the way out of the chassis. Place your other hand underneath the power supply, as shown in Figure 4-10, and slide the power supply completely out of the chassis. If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco part number 800-16727-01) over the opening, and secure it with the captive installation screws.

Removal and Replacement Procedures
Removing and Installing the DC-Input Power Supplies
Removing a 950 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
Follow these steps to remove a DC-input power supply:
Step 1
Identify which PEM is connected to the power supply you are removing (PEM 1 or PEM 2). Verify that
the source power is off to the circuit that is connected to that PEM. (
Figure 4-8
shows the location of the
DC-input PEMs on the Catalyst 6503 switch chassis.)
Note
The system (NEBS) ground serves as the primary safety ground for the Catalyst 6503 and
Catalyst 6503-E chassis that are equipped with DC-input power supplies. The DC-input power
supplies for these chassis do not have a separate ground. Make sure that the chassis you are
working on has the system (NEBS) ground installed.
Step 2
Loosen the captive installation screws on the power supply. (See
Figure 4-9
.)
Step 3
Grasp the power supply handle with one hand, and slide the power supply part of the way out of the
chassis. Place your other hand underneath the power supply, as shown in
Figure 4-10
, and slide the
power supply completely out of the chassis.
Step 4
If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco
part number 800-16727-01) over the opening, and secure it with the captive installation screws.
