1-64 Catalyst 6500 Series Switches Installation Guide OL-5781-08 Chapter 1 Removal and Replacement Procedures Removing and Installing the DC-Input Power Supplies Installing a 6000 W DC-Input Power Supply NoteWith the PWR-6000-DC power supply, you have the option of installing an Input Power Module (IPM) (previously removed) with the DC-input wires and the ground wires still connected. You can then install your power supply and insert the fully-wired IPM. Read through this procedure carefully before installing your power supply. WarningBefore 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 NoteFor proper 6000W DC-input redundant power configuration, all input wires (two pairs for 2800W DC-input, three pairs for 4500W DC-input, and four pairs for 6000W DC-input) for one 6000W DC-input power supply must come from the same battery system (A feed); all input wires (two pairs for 2800W DC-input, three pairs for 4500W DC-input, and four pairs for 6000W DC-input) for the other 6000W DC-input power supply must come from another battery system (B feed). NoteFor multiple DC input power supply, each DC input must be protected by dedicated circuit breaker or fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local or national electrical code requirements. WarningWhen installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046 NoteThe 6000 W DC-input power supply provides power of 2800 W, 4500 W, or 6000 W. Select 2800 W by wiring any two positive (+)/negative (-) terminal pairs in any sequence. Select 4500 W by wiring any three positive (+)/negative (-) terminal pairs in any sequence. Select 6000 W by wiring all four positive (+)/negative (-) terminal pairs. The Cisco IOS software detects the wired inputs and sets the proper system power. NoteThe 6000 W DC-input power supply ground provides the system ground connection when the PWR-6000-DC power supply is installed in a Catalyst 6500 series chassis. Install the ground as described in this procedure. NoteFor redundant power supplies, you must connect the 6000 W DC-input power supply ground for both power supplies.
1-65 Catalyst 6500 Series Switches Installation Guide OL-5781-08 Chapter 1 Removal and Replacement Procedures Removing and Installing the DC-Input Power Supplies NoteYou 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 1Verify 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. CautionUse both hands to install and remove power supplies. Each 6000 W DC-input power supply weighs 35 pounds (16 kg). Step 2Grasp 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 1-46). Figure 1-46 Handling a DC-Input Power Supply Step 3 Tighten the power supply captive installation screw (see Figure 1-47). RUNINSTALL CISCO SYSTEMS, INC1 2 34 INPUT OKFAN OKOUTPUT FAIL

Statement 289 NoteWith the PWR-6000-DC power supply, you have the option of installing an Input Power Module (IPM) (previously removed) with the DC-input wires and the ground wires still connected. You can then install your power supply and insert the fully-wired IPM. If you are going to install an IPM with DC-input wires and ground wires still connected, skip steps 4 through 12 and go directly to step 13. 1Terminal block cover6Captive installation screw 2DC power cable terminal block7 Input Power Module (IPM) 3Ground8IPM captive screws 4Status LEDs9IPM latches 5 Power switch 191286RUNINSTALL CISCO SYSTEMS, INC1 2 34 INPUT OKFA N OKOUTPUT FAIL 1 2 3 4 5 6 7 8 99 8
1-67 Catalyst 6500 Series Switches Installation Guide OL-5781-08 Chapter 1 Removal and Replacement Procedures Removing and Installing the DC-Input Power Supplies Step 4Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power supply (Figure 1-47). Step 5Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according to local and national installation requirements. Use only copper wire. Note6000 W power supplies ship with AWG #4 lugs with 45-degree angled, 2-hole compression lug for both power and ground wiring. Additional lugs for different wire size should be purchased separately. NoteThe power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you use an appropriately sized industry standard 45 degree angled, 2-hole, standard barrel compression lug for both power and ground lugs (for example, on AWG #4 wires, Panduit part number LCC4-14AWH-L or equivalent). The power supply ground studs, located beside the terminal block. NoteFor 6000 W power supplies, use fine-stranded copper conductors rated for 90-degrees Celsius for North American installations. NoteThe 6000 W DC-input power supply provides voltages of 2800 W, 4500 W, or 6000 W. Select 2800 W by wiring any two positive (+)/negative (-) terminal pairs in any sequence. Select 4500 W by wiring any three positive (+)/negative (-) terminal pairs in any sequence. Select 6000 W by wiring all four terminals. The Cisco IOS software detects the wired inputs and sets the proper system power. NoteIf you are wiring for 2800 W for a single power supply, proceed to Step 7; if you are wiring 2800 W for a redundant power supply, proceed to Step 7 and then Step 10. In either case, proceed to step 14 upon completion. NoteIf you are wiring for 4500 W for a single power supply, proceed to Step 8; if you are wiring 4500 W for a redundant power supply, proceed to Step 8 and then Step 11. In either case, proceed to step 14 upon completion. NoteIf you are wiring for 6000 W for a single power supply, proceed to Step 9; if you are wiring 6000 W for a redundant power supply, proceed to Step 9 and then Step 12. In either case, proceed to step 14 upon completion.
