Removing and Installing the DC-Input Power Supplies Chapter 4 Removal and Replacement Procedures Installing 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 When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046 Follow these steps to install a DC-input power supply: Step 1 Step 2 Step 3 Ensure that the system (earth) ground connection has been made. For ground connection installation instructions, see the "Establishing the System Ground" section on page 3-22. Verify that power is off to the DC circuit on 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. Verify that the power switch is in the Off (0) position on the power supply that you are installing. (See Figure 4-11 for the 1300 W DC power supply or Figure 4-12 for the 2500 W DC power supply.) Caution Use both hands to install and remove power supplies. Each Catalyst 6500 series DC-input power supply weighs between 22 pounds (10 kg) and 28 pounds (12.7 kg). Step 4 Step 5 Step 6 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. (See Figure 4-15.) Tighten the power supply captive installation screw. (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 of 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.) 4-22 Catalyst 6500 Series Switches Installation Guide OL-5781-04
