Removing and Installing the DC-Input Power Supplies Chapter 4 Removal and Replacement Procedures Installing the 4000 W Power Supply (Wiring for 2700 W Operation; Left Power Bay) Refer to Figure 4-26 for item location and identification on the 4000 W DC-input power supply. 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 that you are using. Note For proper 2700 W redundant power configurations, source DC for one 4000 W DC-input power supply must come from the same battery system (A feed); source DC for the other 4000 W DC-input power supply must come from another battery system (B feed). Note For multiple DC-input power supplies, each DC input must be protected by a dedicated circuit breaker or a fuse. The circuit breaker or fuse must be sized according to the power supply input rating and the local or national electrical code requirements. To install a 4000 W DC-input power supply and wire it for 2700 W operation in the left power bay (POWER 1), follow these steps: Step 1 Step 2 Step 3 Step 4 Ensure that the system (earth) ground connection has been made. For ground connection installation instructions, see the “Establishing the System Ground” section on page 3-52. Remove the power supply from its shipping container and remove any packaging. Verify that source DC power is off to the DC circuit that feeds 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. Prepare the source DC power cables by attaching the appropriately sized lugs. The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are centered 0.63 inches (15.88 mm) apart and have a 1/4-20 thread. We recommend that you use an appropriately sized industry standard 2-hole, standard barrel compression lug. (See Figure 4-29.) The power supply ground posts, located below the terminal block, also have 1/4-20 threads and require two 1/4-inch split-ring washers and two 1/4-20 hex nuts. The DC-input wires and the DC power supply ground wires should be sized according to the local and national installation requirements. Use only copper wire. For North American installations, use 90°C-rated, fine-strand copper conductors. 4-42 Catalyst 6500 Series Switches Installation Guide OL-5781-08

Each DC-input power supply weighs 32 pounds (14.5 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. (See Figure 4-30.)

Removal and Replacement Procedures<br />
Installing the 4000 W Power Supply (Wiring for 2700 W Operation; Left Power Bay)<br />
Refer to Figure 4-26 for item location and identification on the 4000 W DC-input power supply.<br />
Note<br />
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<br />

to install and secure the DC-input power cables correctly. Incorrectly routing the DC-input power cables<br />
can cause airflow blockage into the power supply and inadequate strain relief in the cables. The exact<br />
amount of space required depends upon the gauge and flexibility of the DC-input power cables that you<br />
are using.<br />

For proper 2700 W redundant power configurations, source DC for one 4000 W DC-input power supply<br />
must come from the same battery system (A feed); source DC for the other 4000 W DC-input power<br />
supply must come from another battery system (B feed).<br />
