Note The information in this chapter applies to all Catalyst 6000 family switches unless otherwise noted. |
This chapter describes how to perform the following removal and replacement procedures for Catalyst 6000 family field-replaceable units (FRUs):
 |
Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system. |
For instructions on installing and replacing modules, refer to the Catalyst 6000 Family Module Installation Guide.
This section describes how to remove and install power supplies for the Catalyst 6000 family switches. A flat-blade or number 2 Phillips screwdriver is required to perform these procedures.
|
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. |
Follow these steps to remove an AC-input power supply:
|
Note In systems with redundant power supplies, you can replace the faulty supply while the system is operating. |
 |
Caution Failure to turn off the power supply could result in equipment damage. |
Step 2 Disconnect the power cord from the power source.
Step 3 Disconnect the power cord from the power supply being removed.
Step 4 Use a flat-blade or number 2 Phillips screwdriver to loosen and remove the captive installation screw (see Figure 5-1).
|
Caution Use both hands to install and remove power supplies. Each Catalyst 6000 family AC-input power supply weighs 22 pounds (9.9 kg). |
Step 5 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the supply, as shown in Figure 5-2.
Step 6 Pull the supply out of the bay and put it aside.
Step 7 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 mounting screws.
Follow these steps to install an AC-input power supply, connect it to a power source, and verify its operation:
Step 2 Turn the power switch to the Off (0) position on the power supply you are installing (see Figure 5-1).
|
Caution Failure to turn off the power supply could result in equipment damage. |
Step 3 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the supply, as shown in Figure 5-2.
|
Caution Use both hands to install and remove power supplies. Each Catalyst 6000 family AC-input power supply weighs 22 pounds (9.9 kg). |
Step 4 Slide the power supply all the way into the power supply bay.
Step 5 Use a flat-blade or number 2 Phillips screwdriver to tighten the captive installation screw (see Figure 5-1).
Step 6 Plug the power cord into the power supply.
Step 7 Connect the other end of the power cord to an AC-input power source.
|
Caution In a system with dual power supplies, connect each power supply to a separate input source. In case of a power source failure, the second source will most likely still be available. |
Step 8 Turn the power switch to the On (|) position on the power supply.
Step 9 Verify 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 "Troubleshooting the Installation" for troubleshooting information.
Follow these steps to remove a DC-input power supply:
|
Warning Before performing the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board for the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. |
Step 2 Turn the power switch to the Off (0) position on the power supply you are removing (see Figure 5-3).
Step 3 Remove the two screws securing the terminal block cover and slide the cover straight off the terminal block (see Figure 5-3).
Step 4 Disconnect the DC-input wires from the terminal block. Disconnect the ground wire last.
|
Warning When installing the unit, the ground connection must always be made first and disconnected last. |
Step 5 Use a screwdriver to loosen and remove the captive screw on the power supply (see Figure 5-3).
|
Caution Use both hands to install and remove power supplies. Each Catalyst 6000 family DC-input power supply weighs 25 pounds (9.9 kg). |
Step 6 Grasp the power supply handle with one hand. Place your other hand underneath as you slowly pull the power supply out of the bay (see Figure 5-4).
Step 7 If the 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 mounting screws. This protects the inner chassis from dust and prevents accidental contact with live voltage at the rear of the bay.
Step 8 Reinstall the power supply terminal block cover.
Follow these steps to install a DC-input power supply, connect it to a power source, and verify its operation:
|
Warning Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. |
Step 2 Verify that power is off to the DC circuit on the power supply you are installing.
Step 3 Turn the power switch to the Off (0) position on the power supply you are installing (see Figure 5-3).
|
Caution Use both hands to install and remove power supplies. Each Catalyst 6000 family DC-input power supply weighs 25 pounds (9.9 kg). |
|
Caution Grasp the power supply handle with one hand. Place your other hand underneath as you slowly insert the power supply into the bay (see Figure 5-4). |
Step 4 Use a screwdriver to tighten the captive screw on the power supply (see Figure 5-3).
Step 5 Remove the two screws securing the terminal block cover and slide the cover straight off the terminal block (see Figure 5-3).
Step 6 Attach the appropriate lugs to the DC-input wires. Maximum width of the lugs is 0.300 inch (7.6 mm). Suggested DC-input wire (90-degree copper conductors) is 8 AWG.
Step 7 Connect the DC-input wires to the terminal block.
Make a sufficient length of wire available to attach to the three terminal block connections.
Connect the DC-input wires to the terminal block (see Figure 5-5). The proper wiring sequence is ground to ground, positive to positive, and negative to negative.
|
Warning When installing the unit, the ground connection must always be made first and disconnected last. |
Step 8 After ensuring that all wire connections are secure, reinstall the terminal block cover.
|
Caution To prevent a short-circuit or shock hazard after wiring the DC-input power supply, reinstall the terminal block cover. |
|
Caution In a system with dual power supplies, connect each power supply to a separate input line. In case of a line failure, the second source will most likely still be available. |
Step 9 Remove the tape from the circuit breaker switch handle and restore power by moving the circuit breaker switch handle to the On (|) position.
Step 10 Turn the power switch to the On (|) position on the power supply.
Step 11 Verify 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 "Troubleshooting the Installation."
This section describes how to remove and install fan assemblies for the Catalyst 6000 family switches. A flat-blade or number 2 Phillips screwdriver is required to perform this procedure.
The fan assembly is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.
Perform these steps to remove the existing fan assembly:
Step 2 Loosen the two captive installation screws by turning them counterclockwise.
Step 3 Grasp the fan assembly with both hands and pull it outward; joggle it if necessary to unseat it from the backplane. Pull it clear of the chassis and place it in a safe place.
Perform these steps to install the new fan assembly:
Step 2 Place the fan assembly into the front chassis cavity so it rests on the chassis, and then lift the fan assembly up slightly aligning the top and bottom guides.
Step 3 Push the fan assembly into the chassis until the captive installation screws meet the chassis.
Step 4 Tighten the captive installation screws by turning them clockwise.
Perform these steps to verify that the new fan assembly is installed correctly:
Step 2 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.
