Note In this publication, the term Catalyst 6500 series refers only to the switch chassis listed in Chapter 1. The Catalyst 6000 series switches (Catalyst 6006 and Catalyst 6009 switches) are described in a separate publication, the Catalyst 6000 Series Switch Installation Guide.
This chapter describes how to perform the following removal and replacement procedures for the Catalyst 6500 series field-replaceable units (FRUs):
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
The online insertion and removal (OIR) feature supported on the Catalyst 6500 series switches allows you to remove and replace modules while the system is online. You can shut down the modules before removal and restart them after insertion without causing other software or interfaces to shut down.
Note Do not remove or install more than one module at a time. After you remove or install a module, check the module LEDs before continuing.
When a module has been removed or installed, the Catalyst 6500 series switch stops processing traffic for the module and scans the system for a configuration change. Each interface type is verified against the system configuration, and then the system runs diagnostics on the new module. There is no disruption to normal operation during the module insertion or removal.
The switch can bring up only an identical replacement module online. To support OIR of an identical module, the module configuration is not removed from the running-config file when you remove a module.
If the replacement module is different from the removed module, you must configure it before the switch can bring it online.
Layer 2MAC addresses are stored in an EEPROM, which allows modules to be replaced online without requiring the system to update switching tables and data structures. Regardless of the types of modules installed, the Layer 2 MAC addresses do not change unless you replace the supervisor engine. If you do replace the supervisor engine, the Layer 2 addresses of all ports change to those specified in the address allocator on the new supervisor engine.
For instructions on installing and replacing modules, refer to the Catalyst 6500 Series Ethernet Modules Installation Guide.
This section describes how to remove and install AC power supplies in the Catalyst 6500 series chassis. The AC-input power supplies have three different form factors, which are not interchangeable between the Catalyst 6500 series chassis. Table 1-1 lists the AC-input power supplies, the chassis that they are supported on, and the corresponding removal and replacement procedures.

Step 6 Loosen the four captive installation screws on the power supply.
Step 7 Grasp both power supply handles, as shown in Figure 1-21,Figure 1-7 and slide the power supply completely out of the chassis and set it aside.
Figure 1-21 Handling a DC-Input Power Supply
Step 8 If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco part number 700-03104-01) over the opening, and secure it with the captive installation screws.
This section provides the procedures for installing a 2700 W DC-input power supply in the Catalyst 6504-E switch chassis. The 2700 W DC-input power supply can operate at either 1350 W or at 2700 W. If you want to operate the power supply at 1350 W you only need to connect one pair of source DC cables to either the VE-1 or the VE-2 lugs on the power supply terminal block. If you want to operate the power supply at 2700 W, you need to connect two pairs of source DC cables to the VE-1 and the VE-2 lugs on the power supply terminal block.
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
Note For proper 2700 W DC-input redundant power configurations, all of the source DC for one 2700 W DC-input power supply must come from the same battery system (A feed); all of the source DC for the other 2700 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 the 2700 W DC-input power supply in the Catalyst 6504-E chassis and cable it to source DC, follow these steps:
Step 1 Ensure that the system (earth) ground connection has been made. For system ground connection installation instructions, see the “Establishing the System Ground” section.
Step 2 Remove the power supply from its shipping container and remove any packaging material.
Step 3 Locate the plastic bags that accompanied the power supply and set them aside. One bag contains one source DC cable guide, terminal block cover (plastic) with four screws, and two cable ties. The other plastic bag contains the 1/4-20 nuts and lock-washers for the terminal posts. You will use these items later in the procedure.
Step 4 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 DC 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.
Step 5 Grasp both power supply handles, as shown in Figure 1-22Figure 1-7. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay. Tighten the four captive installation screws.
Warning Power supply captive installation screws must be tight to ensure protective grounding continuity. Statement 289
Figure 1-22 Installing the Power Supply in the Chassis
Step 6 Determine whether you will be routing the source DC cables on the left- or right-side of the power supply. Loosen and remove the two screws securing the top half of the fixed cable guide on the side you will be routing the source DC cables. Remove the top half of the cable guide and set it and the screws aside.
Step 7 Attach the appropriate size and type of lugs to the source DC cables and the ground cable.
The maximum width of a lug is 0.300 inch (7.6 mm). The source DC cables and the ground cable must be sized according to local and national installation requirements. Use only copper wire. 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. The power supply ground posts also have 1/4-20 threads and require two 1/4-inch split-ring washers and two 1/4-20 hex nuts (one for each post).
Note For 2700 W power supplies, use fine-stranded copper conductors that are rated for 90°C Celsius for North American installations.
Note For proper 2700 W DC-input redundant power configurations, all of the source DC for one 2700 W DC-input power supply must come from the same battery system (A feed); all of the source DC for the other 2700 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.
Step 8 Connect the source DC cable lugs to the 2700 W power supply terminal block posts (Figure 1-23) in this order:
Note If you are only going to install one pair of source DC cables (1350 W operation), you can attach the source DC cables to either the VE-1 or VE-2 pair of terminal posts. Also notice that there is only one ground connection on the power supply faceplate.
Figure 1-23 Attaching the Source DC Cables and the Ground Cable
Position the source DC cables in the fixed cable guide. Place the top half of the fixed cable guide over the source DC cables and secure the top half of the cable guide to the bottom half with two screws. Figure 1-24 shows how the source DC cables are routed from the left side of the power supply.
Warning When installing the unit, always make the ground connection first and disconnect it last. Statement 42
Step 9 Route and secure the ground cable to the fixed cable guide loops with the two cable-ties supplied with the power supply. (See Figure 1-24.)
Step 10 Position the clear plastic terminal block cover over the terminal block and secure it to the power supply using the four supplied screws. (See Figure 1-24.)
Figure 1-24 Securing the Cables to the Cable Guides
Step 11 Install the detached source DC cable guide that is supplied with the power supply (see Figure 1-25):
a. Position the thicker half of the cable guide under the two or four source DC cables and align the cables with the grooves in the cable guide. The cable guide should be placed between the terminal block and the fixed cable guide.
b. Place the upper half of the cable guide over the source DC cables and secure the two halves of the cable guide together with the two supplied screws. Do not tighten the screws at this time.
c. Slide the cable guide toward the terminal block and position it as close to the terminal block as possible.
d. Tighten the two cable guide screws.
e. Place a tie wrap around the source DC cables near the detached cable guide. Position the tie wrap next to the detached cable guide and tighten the tie wrap securely. Make sure that the detached cable guide cannot slide away from the terminal block.

Step 12 Remove the warning flags and cautionary tape from the source DC mains and switch the source DC on.
Step 13 Verify the power supply operation by checking that the power supply front panel LEDs are in the following states:
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section.
This section covers the power supply removal and installation procedures for the 4000 W DC-input power supply and is divided into the following topics:
Note For proper 4000 W DC-input redundant power configurations, all of the source DC for one 4000 W DC-input power supply must come from the same battery system (A feed); all of the source DC for the other 4000 W DC-input power supply must come from another battery system (B feed).
The 4000 W DC-input power supply can operate at either 2700 W or at 4000 W. If you want to operate the power supply at 2700 W, you need to connect two pairs of source DC cables to the VE-1 and the VE-2 posts on the power supply terminal block. If you want to operate the power supply at 4000 W, you need to connect a third pair of source DC cables to the VE-3 terminal block posts.
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.
Figure 1-26 shows the features on a 4000 W DC-input power supply. Use the illustration for reference as you remove and install the power supply.

The following tools are required for the power supply removal and installation procedures:
Additional tools might be necessary to install the lugs on the source DC and the ground cables. Additionally, the lugs for the source DC cables and the ground cable are not provided; you must obtain them on your own.
Warning When installing the unit, always make the ground connection first and disconnect it last. Statement 42
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 Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock, keep hands and fingers out of the power supply bays and backplane areas. Statement 166
To remove a 4000 W DC-input power supply, follow these steps:
Step 1 Verify that power is off to the DC circuit that feeds power to 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.
Step 2 Turn the power switch to the off (0) position on the power supply that you are removing. (See Figure 1-26.)
Turning off the power switch also disengages a pawl that unlocks the power supply from the chassis.
Note Figure 1-26 shows the PWR-4000-DC power supply with an outer terminal block cover. An earlier version of this power supply does not have an outer terminal block cover. To order a retrofit kit containing this cover, use Cisco Systems part number CVR-4000DC-TERM=.
Step 3 Remove the two screws securing the outer terminal block cover. Lift the cover up to detach the two tabs from the slots on the power supply. Remove the cover and set it aside along with the screws. (See Figure 1-26.)
Step 4 Remove the two screws securing the left inner terminal block cover (covering the VE-1/VE-2 terminal block). Lift up on the cover to detach the tab from the slot on the power supply. Remove the cover and set it aside along with the screws.
Step 5 Remove the one screw securing the right inner terminal block cover (covering the VE-3 terminal block). Lift up on the cover to detach the tab from the slot on the power supply. Remove the cover and set it aside along with the screw.
Step 6 Disconnect the source DC cables from the terminal blocks in this order:
1. Positive (+) source DC cables from the +VE-1, +VE-2, and +VE-3 terminal posts
2. Negative (–) source DC cables from the –VE-1, –VE-2, and –VE-3 terminal posts
3. Ground cable from the ground terminal posts
You must remove all DC-input wiring from both terminal blocks before physically removing the power supply chassis.
Step 7 Loosen the captive installation screw on the power supply. (See Figure 1-27.)
Step 8 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 1-28,Figure 1-7 and slide the power supply completely out of the chassis and set it aside.
Figure 1-27 Source DC Cable Connections for 4000-W DC-Input Power Supply
Figure 1-28 Handling a 4000 W DC-Input Power Supply
Step 9 If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco part number 700-03104-01) over the opening, and secure it with the captive installation screw.
The 4000 W DC-input power supply can be wired for either 2700 W or 4000 W operation. The type of power output from the power supply determines the number of source DC power cables and how they are routed and connected in the chassis.

When installing a 4000 W DC-input power supply, observe the following guidelines:
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.
Note The 4000 W DC-input power supply does not operate with only one pair of source DC cables connected.
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 Power supply captive installation screws must be tight to ensure protective grounding continuity. Statement 289
Refer to Figure 1-26 for a front view of the power supply with the major features called out.
Note Figure 1-26 shows the PWR-4000-DC power supply with an outer terminal block cover. An earlier version of this power supply does not have an outer terminal block cover. To order a retrofit kit containing this cover, use Cisco Systems part number CVR-4000DC-TERM=.
Refer to Figure 1-26 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 Ensure that the system (earth) ground connection has been made.
For ground connection installation instructions, see the “Establishing the System Ground” section.
Step 2 Remove the power supply from its shipping container and remove any packaging.
Step 3 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.
Step 4 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 1-29.) 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.
Figure 1-29 DC Power Cable Lug
Step 5 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 1-30.)
Figure 1-30 Handling a 4000 W DC-Input Power Supply
Step 6 Tighten the power supply captive installation screw. (See Figure 1-26.)
Step 7 Remove the two screws that secure the outer terminal block cover. Lift the cover up to detach the cover tabs from the slots in the power supply. Set the cover and the screws aside.
Step 8 Remove the two screws that secure the left inner terminal block cover. Lift up on the cover to detach the cover tab from the slot in the power supply. Set the cover and the screws aside.
Step 9 Remove the one screw that secures the right inner terminal block cover. Lift up on the cover to detach the cover tab from the slot in the power supply. Set the cover and the screw aside.
Step 10 Remove the two plastic insulators from the plastic bag that shipped with the power supply. Position the larger plastic insulator (eight holes) over the eight-post terminal block (VE-1/VE-2). Align the holes in plastic with the terminal block posts. The end flap on the insulator should face away from the DC source cable entry direction.
Step 11 Position the smaller plastic insulator (four holes) over four-post terminal block VE-3. Align the holes in the plastic with the terminal block posts. The end flap on the insulator should face away from the DC source cable entry direction.
Step 12 Fold the end flaps down on both insulators to cover the open side of the terminal blocks (opposite side from cable entry).
Note Be sure to place a plastic insulator over both terminal blocks, even if you are not attaching source DC cables to it; this ensures that the plastic insulator is available for future use.
Step 13 From the left side of the power supply, connect the power supply ground cable and the source DC cables to the power supply terminal blocks in this order (Figure 1-31):
1. Ground cable lug to the ground terminal posts
2. Negative (–) source DC cables to any two pairs of (–) terminal posts (VE-1 and VE-2, VE-1 and VE-3, or VE-2 and VE-3)
3. Positive (+) source DC cables to any two pairs of (+) terminal posts (VE-1 and VE-2, VE-1 and VE-3, or VE-2 and VE-3)
Figure 1-31 DC-Input Wire Connections for 2700 W Operation (Left-Side Power Bay)
Step 14 Wrap the large perforated flaps of the insulators around each pair of source DC cables, inserting each locking tab into the rear of the slot. Pull the tab until the cover is secured around the power cabling trim, and discard excess tab plastic.
Step 15 Position and secure the left inner terminal block cover with two screws. Position and secure the right inner terminal block cover with one screw.
Step 16 Install and secure the outer terminal block cover with the two screws.
Step 17 If you are installing a second power supply operating at 2700 W in the right-side power supply bay, proceed to “Installing the 4000 W Power Supply (Wiring for 2700 W Operation; Right Power Bay)” section; otherwise, go to Step 18.
Step 18 After you confirm that all installation steps are completed correctly, remove any safety flags, lockout devices, or adhesive tape from the source DC circuit breakers, and energize the input circuits to the power supplies.
Step 19 Turn the power switch to the on (|) position on the power supply. Turning on the power switch also engages a pawl that locks the power supply in the chassis.
Step 20 Verify the power supply operation by ensuring that the power supply front panel LEDs are in the following states:
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section.
See Figure 1-26 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).

Step 1 Ensure that the system (earth) ground connection has been made.
For ground connection installation instructions, see the “Establishing the System Ground” section.
Step 2 Remove the power supply from its shipping container and remove any packaging.
Step 3 Verify that source DC 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.
Step 4 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 1-32.) 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.

Step 9 Remove the one screw that secures the right inner terminal block cover. Lift up on the cover to detach the cover tab from the slot in the power supply. Set the cover and the screw aside.
Step 10 Remove the two plastic insulators from the plastic bag that shipped with the power supply. Position the larger plastic insulator (eight holes) over terminal block VE-1/VE-2. Align the holes in plastic with the terminal block posts. The end flap on the insulator should face away from the DC source cable entry direction.
Step 11 Position the smaller plastic insulator (four holes) over the four-post terminal block VE-3. Align the holes in the plastic with the terminal block posts. The end flap on the insulator should face away from the source DC cable entry direction.
Step 12 Fold the end flaps down on both insulators to cover the open side of the terminal block (opposite side from cable entry).
Note Be sure to place a plastic insulator over both terminal blocks, even though you might not attach source DC cables to the terminal block; installing both of the insulators ensures that they are available for future use.
Step 13 From the right side of the power supply, connect the power supply ground cable and the source DC cables to the DC-input wires to the terminal block (Figure 1-34) in this order:
1. Ground cable lug to the ground terminal posts
2. Negative (–) source DC cables to any two pairs of (–) terminal posts (VE-1 and VE-2, VE-1 and VE-3, or VE-2 and VE-3)
3. Positive (+) source DC cables to any two pairs of (+) terminal posts (VE-1 and VE-2, VE-1 and VE-3, or VE-2 and VE-3)

Step 15 Wrap the large perforated flaps of the insulators around each pair of source DC cables, inserting each locking tab into the rear of the slot. Pull the tab until the cover is secured around the power cabling trim, and discard excess tab plastic.
Step 16 Position and secure the left inner terminal block cover with two screws. Position and secure the right inner terminal block cover with one screw.
Step 17 Using the cable tie provided, place the cable tie through the slot at the top of the left terminal block cover, and secure the wiring to the right terminal block.
Step 18 Install and secure outer terminal block cover with the two screws.
Step 19 If you are installing a second power supply that operates at 4000 W in the right side power supply bay, proceed to “Installing the 4000 W Power Supply (Wiring for 4000 W Operation; Right Power Bay)” section; otherwise, go to Step 20.
Step 20 After you confirm that all installation steps are completed correctly, remove any safety flags, lockout devices, or adhesive tape from the source DC circuit breakers, and energize the input circuits to the power supplies.
Step 21 Turn the power switch to the on (|) position on the power supply. Turning on the power switch also engages a pawl that locks the power supply in the chassis.
Step 22 Verify the power supply operation by ensuring that the power supply front panel LEDs are in the following states:
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section.
See Figure 1-26 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 you are using.
Note For proper 4000 W DC-input 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 4000 W operation in the right power bay (POWER 2), follow these steps:
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection installation instructions, see the “Establishing the System Ground” section.
Step 2 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.
Step 3 Prepare the source DC-input 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 1-38.) 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.
Figure 1-38 DC Power Cable Lug
Step 4 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 1-39.)

Step 5 Tighten the power supply captive installation screws
Step 6 Remove the two screws that secure the outer terminal block cover Lift the cover up to detach the cover tabs from the slots in the power supply. Set the cover and the screws aside
Step 7 Remove the two screws that secure the left inner terminal block cover. Lift up on the cover to detach the cover tab from the slot in the power supply. Set the cover and the screws aside.
Step 8 Remove the one screw that secures the right inner terminal block cover. Lift up on the cover to detach the cover tab from the slot in the power supply. Set the cover and the screw aside.
Step 9 Remove the two plastic insulators from the plastic bag that shipped with the power supply. Position the larger plastic insulator (eight holes) over terminal block VE-1/VE-2. Align the holes in plastic with the terminal block posts. The end flap on the insulator should face away from the DC source cable entry direction.
Step 10 Position the smaller plastic insulator (four holes) over the four-post terminal block VE-3. Align the holes in the plastic with the terminal block posts. The end flap on the insulator should face away from the source DC cable entry direction.
Step 11 Fold the end flaps down on both insulators to cover the open side of the terminal block (opposite side from cable entry).
Step 12 From the right side of the power supply, connect the power supply ground cable and the source DC cables to the DC-input wires to the terminal block (see Figure 1-40) in this order:
1. Ground cable lug to the ground terminal posts
2. Negative (–) source DC cables to terminal posts –VE-1 and –VE-2
3. Positive (+) source DC cables to terminal posts +VE-1 and +VE-2
Step 13 From the right side of the power supply, connect the third pair of source DC cables to the power supply terminal block VE-3 (see Figure 1-40) in this order:
1. Negative (-) source DC cable to terminal posts –VE-3
2. Positive (+) source DC cable to terminal posts +VE-3
Figure 1-40 DC-Input Wire Connections for 4000 W Operation (Right-Side Power Bay)
Step 14 Wrap the large perforated flaps of the insulators around each pair of source DC cables, inserting each locking tab into the rear of the slot. Pull the tab until the cover is secured around the power cabling trim, and discard excess tab plastic.
Step 15 Position and secure the left inner terminal block cover with two screws. Position and secure the right inner terminal block cover with one screw.
Step 16 Using the cable tie provided, place the cable tie through the slot at the top of the right terminal block cover, and secure the wiring to the left terminal block.
Step 17 Install and secure outer terminal block cover with the two screws.
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Step 18 After you confirm that all installation steps are completed correctly, remove any safety flags, lockout devices, or adhesive tape from the source DC circuit breakers, and energize the source DC circuits to the power supplies.
Turn the power switch to the On (|) position on the power supply. Turning on the power switch also engages a pawl that locks the power supply in the chassis.
Step 19 Verify the power supply operation by ensuring that the power supply front panel LEDs are in the following states:
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section.
This section covers the power supply removal and installation procedures for the 6000 W DC-input power supply (PWR-6000-DC) and is divided into the following topics:
Note For proper 6000 W DC-input redundant power configurations, all of the source DC for one 6000 W DC-input power supply must come from the same battery system (A feed); all of the source DC for the other 6000 W DC-input power supply must come from another battery system (B feed).
The following tools are required for the power supply removal and installation procedures:
Additional tools might be necessary to install the lugs on the source DC and the ground cables. Additionally, the lugs for the source DC cables and the ground cable are not provided; you must obtain them on your own.
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

If the LEDs indicate a power problem, see the “Identifying Startup Problems” section.
This section describes how to remove and install fan trays for the Catalyst 6500 series switches.
Note If your Catalyst 6506, Catalyst 6509, or Catalyst 6509-NEB chassis is equipped with a Supervisor Engine 2 and you using the fan tray removal and replacement procedure to upgrade the chassis from a fan tray 1 (low-speed) to a fan tray 2 (high-speed), you must first check the chassis configuration using the hw-module fan-tray version 2 command to check for configuration problems, such as power supply compatibility and power sufficiency. If the system does not detect any configuration issues, a message is displayed saying that it is OK to change the fan trays. This command applies to Catalyst 6500 series switches that are configured with a Supervisor Engine 2 only. This command is not required in systems that are configured with either a Supervisor Engine 720 or a Supervisor Engine 32.
You might need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive installation screws on the fan tray.
The fan Tray is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.
Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258
To remove the existing fan assembly, follow these steps:
Step 1 If you are upgrading your chassis from a fan tray 1 (low speed) to a fan tray 2 (high speed) and your chassis is equipped with a Supervisor Engine 2, you need to check that the current chassis configuration supports the fan tray upgrade. To do this, use the command hw-module fan-tray version 2 to check for configuration problems, such as power supply compatibility and power sufficiency.
If the system does not detect any configuration issues, a message is displayed saying that it is OK to change the fan trays. If your chassis has either a Supervisor Engine 32 or a Supervisor Engine 720, skip this step and proceed to Step 2.
Step 2 Locate the fan assembly in the chassis as follows:
Note Make sure there is adequate slack in the network interface cables to allow the cable guide to pivot down far enough to access the fan tray. If there is insufficient slack in the cables, the cable guide will not pivot far enough to give you access to the fan trays.
Step 3 Loosen the two fan tray captive installation screws by turning them counterclockwise.
Step 4 Grasp the fan assembly with both hands, and pull it outward; rock it gently, if necessary, to unseat the fan assembly power connector from the backplane.
Step 5 Pull the fan assembly clear of the chassis, and set it aside.

To install the new fan assembly, follow these steps:
Step 1 Hold the fan assembly with the fans facing to the right and the FAN STATUS LED at the bottom.
For the Catalyst 6509-NEB switch, hold the fan assembly with the fans facing down and the FAN STATUS LED on the left. (See Figure 1-68.) For the Catalyst 6509-NEB-A and the Catalyst 6509-V-E switches, hold the fan assembly so that the handle is at the top of the assembly. (See Figure 1-70.)
Step 2 Place the fan assembly into the front chassis cavity so that it rests on the chassis, and then lift the fan assembly up slightly, aligning the top and bottom chassis guides.
Step 3 Push the fan assembly into the chassis until the power connector seats in the backplane and the captive installation screws make contact with the chassis.
Step 4 Tighten the captive installation screws.
Step 5 On the Catalyst 6509-NEB-A and the Catalyst 6509-V-E switches, fold the cable guide up, and tighten the two captive installation screws at the top of the chassis. (See Figure 1-69.)
To verify that the new fan assembly is installed correctly, follow these steps:
Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that the fan assembly is inserted completely in the chassis and that the faceplate is flush with the switch back panel.
Step 2 Verify that the FAN STATUS LED is green. If the LED is red, one or more of the fans are faulty.
Step 3 If after several attempts the fans do not operate or if you experience trouble with the installation (for instance, if the captive installation screws do not align with the chassis holes), contact a Cisco customer service representative for assistance.
This section describes how to install the optional air filter assembly for the Catalyst 6509-NEB-A switch or the Catalyst 6509-V-E switch. The filter assembly is designed to prevent dust and other contaminants from being drawn into the switch chassis. It is not included with the chassis or bundle configurations because it is not needed in normal installation environments. We recommend that you use this assembly only in exceptionally dusty installation sites.
The necessary parts can be ordered as listed in Table 1-3 . The filter assembly installation requires that INTAKEPNL-09= be installed on the chassis. This intake panel can be identified by the two filter assembly support loops extending from the bottom front of the panel and the thumbscrews on the front left and right sides of the panel. (See Figure 1-74.)

To install the new filter assembly, follow these steps. If INTAKEPNL-09= is already installed, skip to Step 3.
Step 1 Remove the intake panel by unscrewing four thumbscrews. (See Figure 1-73.)
Figure 1-73 Removing the Intake Panel
Step 2 Install the new intake panel by tightening four thumbscrews. (See Figure 1-74.)

Step 6 Install the filter assembly with the tabs facing the floor, as follows:
a. Fit the tabs (see Figure 1-76) on the bottom of the filter cage assembly into the lower support loops. (See Figure 1-74.)
b. Rotate the filter assembly towards the intake panel. (See Figure 1-77.)
c. Tighten the two fastening screws.

Step 7 After installing the optional air filter assembly, establish a schedule for visually checking the air filter for contamination. (See “Checking the Air Filter” section.)
Once you have installed the optional air filter assembly on the Catalyst 6509-NEB-A or Catalyst 6509-V-E switch chassis, you need to periodically check the air filter for damage and cleanliness. We recommend that you perform a visual inspection of the filter at least once a month, or more often in dusty environments. Replace the filter if appears clogged with dust, or you have detected an increase in the chassis internal operating temperature. Failure to periodically check the filter can result in restricted airflow through the filter leading to chassis overheating and degraded EMI performance.
The remote power cycling feature allows you to power down and power up a switch chassis through the network rather than being physically present to turn the power supply power switch off and on. The remote power cycling feature is only available on the 8700 W AC-input power supply.
Several vendors make remote power cycling relay controller boxes that can be used to power cycle the Catalyst 6500 series switch chassis. Most of these relay controller boxes have the capability of controlling multiple power supplies. The relay controller boxes have a network interface that allows the user to remotely access the relay controller box and toggle a built-in relay. The built-in relay can be either a normally open (NO) type or a normally closed (NC) type of relay. We strongly recommend that you purchase a relay controller box that uses a NO relay. The relay controller box is installed near the switch chassis and is attached to the network. Two control wires extend from the relay controller box to a three-position terminal block located on the front of the 8700 W power supply. A signal from the relay controller box travels through the control wires to toggle the power supply on or off.
This section only describes how to install the remote power cycling feature control wires; relay controller box installation instructions should be provided by the maker of the relay controller box.
Note The remote power cycling feature and this installation procedure are applicable only for the 8700 W AC-input power supply.
The following tools and components are required to perform this procedure:
We strongly recommend that you purchase a relay controller box that uses a NO (normally open) relay to control the remote power cycling.
To install the two control wires from the relay controller box to the 8700 W power supply, follow these steps:
Step 1 Remove the relay controller box from its shipping packaging.
Step 2 Install the relay controller box following the installation documentation supplied with the product.
Step 3 Measure and cut two pieces of 18 AWG control wire long enough to run between the relay controller box terminals and the terminal block on the 8700 W power supply.
Step 4 Strip approximately 1/4-inch of insulation from each end of both control wires.
Step 5 Connect the two control wires to the relay controller box terminals following the instruction documentation supplied with the relay controller box.
Step 6 Identify which pair of terminals on the power supply terminal block (either terminals 1 and 2 for a NO relay (recommended) or terminals 2 and 3 for a NC relay) where you need to connect the control wires. Using a small flat-blade screwdriver, depress the wire release mechanism for one of the terminals on the power supply terminal block and insert the bare wire into the terminal. (See Figure 1-78.) Remove the screwdriver to secure the wire. Gently tug on the wire to verify that it is secure in the terminal block.
Step 7 Repeat Step 6 for the second control wire.
Figure 1-78 Installing the Relay Control Wires
Step 8 Check the position of the relay controller switch located next to the terminal block.
The switch should be in the down, NO (normally open) position if the relay controller box uses a NO relay. This the default and the recommended position. If the relay controller box uses a NC relay, the relay controller switch should be in the up position.
You are now ready to install the ferrite bead on the control wires. Follow the installation instructions supplied in the package containing the ferrite bead or the installation procedure in the next section.
The ferrite bead is a passive device that limits high-frequency interference on interface and control cables, and it is only required when you install the remote power-cycling feature that is supported only by the 8700 Watt power supply. The ferrite bead is installed on the two control wires that link the external relay controller box with the remote power-cycling terminal block on the 8700 W power supply. You do not need the ferrite bead for 8700 Watt power supply installations that do not include the remote power-cycling feature.
To install the ferrite bead on the remote power-cycling control wires, follow these steps:
Step 1 Remove the ferrite bead and the two plastic ties from the plastic bag.
Step 2 Open the ferrite bead as shown in Figure 1-79, View A.
Step 3 Place the two remote power-cycling control wires (18 AWG maximum) in the ferrite bead as shown in Figure 1-79, View B. Close the ferrite bead making sure that the two halves have completely snapped together and are secure.
Step 4 Locate a point on the remote power-cycling control wires that leaves approximately 1 to 2 inches (2.5 to 5 cm) of exposed wire from the remote power cycling terminal block located on the front of the power supply. Wrap one of the 4-inch plastic ties around the remote power-cycling control wires at that point. Tighten the plastic tie so that it is snug against the control wires and cannot slide. See Figure 1-79, View C.
Step 5 Slide the ferrite bead so that it is positioned just behind the first plastic tie wrap. Take the second plastic tie and wrap it around the control wires directly behind the ferrite bead and tighten it so that the ferrite bead cannot slide up or down the control wires. See Figure 1-79, View C.
Step 6 To finish the procedure, trim the excess plastic strap from the two plastic tie wraps.
