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. |
This chapter contains the removal and replacement procedures for Catalyst 4003 and 4006 field-replaceable units (FRUs):
For instructions on installing and replacing supervisor engine and switching modules, see "Installing the Modules."
This section describes how to remove and install the AC-input power supply (see Figure 4-1) and DC-input power supply (see Figure 4-2) for the Catalyst 4003 and 4006 switches and is divided into the following sections:
|
Warning Keep hands and fingers out of the power supply bays. High voltage is present on the power backplane when the system is running. |
A Phillips screwdriver is required to perform these procedures.
Follow these steps to remove the AC-input power supply:
Step 2 Disconnect the power cord from the power supply being removed.
Step 3 Loosen the two captive installation screws (see Figure 4-1).
Step 4 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the power supply, as shown in Figure 4-3.
 |
Caution Use both hands to install and remove power supplies. |
Step 5 Pull the supply out of the bay and set it aside.
Step 6 If the power supply bay is to remain empty, install a blank power supply filler plate over the opening. Secure the filler plate with the two mounting screws, tightening them with a screwdriver.
Follow these steps to install an AC-input power supply:
Step 2 Remove the two Phillips-head screws from the power supply filler plate.
Step 3 Remove the power supply filler plate and set it aside.
Step 4 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the power supply, as shown in Figure 4-3.
|
Caution Use both hands to install and remove power supplies. |
Step 5 Slide the power supply all the way into the power supply bay.
Step 6 Use a screwdriver to tighten the two captive installation screws (see Figure 4-1) on the front panel of the AC-input power supply.
Step 7 Before you connect the power supply to a power source, ensure that all site power and grounding requirements described in the Site Preparation and Safety Guide have been met.
Step 8 Plug the power cord into the power supply.
Step 9 Connect the other end of the power cord to an AC-power input source.
|
Caution In a system with multiple power supplies, connect each power supply to a separate AC power source. In case of a power source failure, the second source will probably still be available and can maintain maximum overcurrent protection for each power connection. |
Step 10 Verify power supply operation by checking the power supply front panel LEDs:
Step 11 Check the power supply and system status from the system console by entering the show system command. For more information on commands, refer to the Command Reference publication for your switch.
Step 12 If the LEDs or the show system command output indicate a power problem or other system problem, see "Troubleshooting the Installation," for more information.
|
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. |
 |
Note A small flat blade screwdriver as required for the terminal block wiring. |
Follow these steps to remove a DC-input power supply:
Step 2 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 3 Use a screwdriver to loosen and remove the captive screw on the power supply (see Figure 4-2).
Step 4 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 4-3).
Step 5 If the bay is to remain empty, install a blank power supply filler plate 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.
|
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. |
|
Note A small flat blade screwdriver as required for the terminal block wiring. |
|
Note Ensure that the system (earth) ground connection has been made. For ground connection installation instructions, see the "Connecting System Ground" section. |
Follow these steps to install a DC-input power supply, connect it to a power source, and verify its operation:
Step 2 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 4-3).
Step 3 Use a screwdriver to tighten the captive screws on the power supply (see Figure 4-2).
Step 4 Strip input wiring insulation approximately 0.2 inch (5mm) and attach to input terminal block using small flat blade screwdriver.
Step 5 Connect the DC-input wires to the DC-input power supply connector.
Connect the DC-input wires to the terminal block. 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 6 Before you connect the power supply to a power source, ensure that all site power and grounding requirements described in the Site Preparation and Safety Guide have been met.
Step 7 Connect the other end of the power cord to a DC-power input source.
|
Caution In a system with multiple power supplies, connect each power supply to a separate DC power source. In case of a power source failure, the second source will probably still be available and can maintain maximum overcurrent protection for each power connection. |
Step 8 Verify power supply operation by checking the power supply front panel LEDs:
Step 9 Check the power supply and system status from the system console by entering the show system command. For more information on commands, refer to the Command Reference publication for your switch.
Step 10 If the LEDs or the show system command output indicate a power problem or other system problem, see "Troubleshooting the Installation," for more information.
This section describes how to remove and install the chassis fan assembly for the Catalyst 4003 and 4006 switches (see Figure 4-4 and Figure 4-5). The fan assembly is designed to be removed for a short period and replaced while the system is operating.
A Phillips screwdriver is required to perform this procedure.
|
Caution Never operate the system for an extended period if the fan assembly is removed or if it is not functioning properly. An overtemperature condition can cause severe equipment damage. |
Follow these steps to remove the existing chassis fan assembly:
Step 2 Grasp the fan assembly with both hands and pull it outward; wiggle it if necessary to unseat it from the backplane. Slide it out of the chassis and place it in a safe place.
Follow these steps to install the new fan assembly:
Step 2 Place the fan assembly into the fan assembly bay so it rests on the chassis, and then lift the fan assembly up slightly aligning the top and bottom guides.
Step 3 Slide the fan assembly into the chassis until the two captive installation screws make contact with the chassis.
Step 4 Use a screwdriver to tighten the two captive installation screws by turning them clockwise.
|
Note To check the operation of the fans, you need to power up the chassis. |
Follow 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.
