Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Checking the VTT Module and Clock Module

To check the status of your module, do one of the following:

•On systems running Catalyst software, enter the show environment command.

This example shows how to check the status of the VTT modules and clock modules on a system running Catalyst software: 

Console> show environment 

Environmental Status (. = Pass, F = Fail, U = Unknown, N = Not Present)

  PS1:.     PS2:N     PS1 Fan:.     PS2 Fan:N

  Chassis-Ser-EEPROM:.     Fan:.

  Clock(A/B):B         Clock A:F     Clock B:.

  VTT1:.    VTT2:F    VTT3:.

Console>

The above example shows a failure with clock module A and VTT module 2.

•On systems running Cisco IOS software, enter the show environment status command.

This example shows how to check the status of the VTT modules and clock modules on a system running Cisco IOS software: 

Router> show environment status

backplane:

   operating clock count:1

   operating VTT count:2

...

VTT 1:

  VTT 1 OK: OK

VTT 2:

  VTT 2 OK: not OK

VTT 3:

  VTT 3 OK: OK

clock 1:

  clock 1 OK: not OK, clock 1 clock-inuse: not-in-use

clock 2:

  clock 2 OK: OK, clock 2 clock-inuse: in-use

...

Router>

The above example shows a failure with clock module A (clock 1) and VTT module 2.

Replacing the VTT Modules and Clock Modules

This section consists of these subsections:

•Removing the Front Panel Safety Cover

•Locating the VTT Modules and Clock Modules

•Replacing the VTT Module

•Replacing the Clock Module

Removing the Front Panel Safety Cover

To replace the VTT modules or clock module, you must first shut down the switch and remove the front (non-module) panel safety cover of the switch chassis.

Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.

To remove the front panel safety cover, perform these steps:

Step 1 On any modules running Cisco IOS software, save the running configuration.

Step 2 Shut down the switch and unplug all power cords to all power supplies.

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Step 3 Use a Phillips screwdriver to remove the front panel screws:

•16 screws on the Catalyst 6006 and 6506 chassis

•18 screws on the Catalyst 6009 and 6509 chassis

•8 screws on the Catalyst 6509-NEB and Cisco 7609 (OSR-7609) chassis (4 on the top, 4 on the bottom)

•20 screws on the Catalyst 6509-NEB-A and Cisco 7609 (CISCO7609) chassis

•22 screws on the Catalyst 6513 and Cisco 7613 chassis

Locating the VTT Modules and Clock Modules

See Figure 1 for the location of the VTT modules and clock modules on the Catalyst 6500 series switches, and the Cisco 7609 (OSR-7609 and CISCO7609) and 7613 routers.

Note Do not use the WS-C6K-CL= clock module in the Catalyst 6509-NEB-A switch and Cisco 7609 router (CISCO7609). Instead, use the CLK-7600= clock module. For more information, refer to the Cisco Clock Module CLK-7600 Installation Note at this URL:

http://www.cisco.com/univercd/cc/td/doc/product/core/cis7600/hardware/78_15002.htm

Note The location of the VTT modules and clock modules is the same on the Catalyst 6006, 6009, 6506, and 6509 switches.

Replacing the VTT Module

Note The manufacturing assembly number for the VTT modules on Catalyst 6500 series switches that were shipped since December 2001 is 73-4354-02 Rev A0. If the VTT modules installed on your switch do not have this manufacturing assembly number, you must replace all three VTT modules, regardless of the failure.

If all VTT module manufacturing assembly numbers are 73-4354-02 Rev A0, replace only the failed module.

Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.

Note Note the position of the VTT module before you remove it from the switch chassis because you must install the new VTT module in the same position.

To replace the VTT module, perform these steps:

Step 1 Remove the two screws that secure the VTT module.

Step 2 Gently lift and remove the VTT module, placing it on an antistatic mat or foam.

Step 3 Remove the new VTT from the antistatic bag.

Step 4 Hold the module with the connector away from you.

Step 5 Carefully press the module onto the connector.

Step 6 Replace the two securing screws.

Step 7 Repeat Step 1 through Step 6 to install any additional VTT modules.

Step 8 Replace the front panel safety cover and power up the switch.

Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.

Step 9 Enter the show environment or show environment status command to verify the status of the replaced module.

This example shows that the VTT module is functioning properly: 

Console> show environment 

Environmental Status (. = Pass, F = Fail, U = Unknown, N = Not Present)

  PS1:.     PS2:N     PS1 Fan:.     PS2 Fan:N

  Chassis-Ser-EEPROM:.     Fan:.

  Clock(A/B):A         Clock A:.     Clock B:.

  VTT1:.    VTT2:.    VTT3:.

Console>

Replacing the Clock Module

Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.

Note Note the position of the clock module before you remove it from the switch chassis because you must install the new clock module in the same position.

To replace the clock module, perform these steps:

Step 1 Remove the four screws that secure the clock module.

Step 2 Gently lift and remove the module, placing it on an antistatic mat or foam.

Step 3 Remove the new clock from the antistatic bag.

Step 4 Hold the module with the connector away from you.

Step 5 Carefully press the module onto the connector.

Step 6 Replace the four securing screws.

Step 7 Repeat Step 1 through Step 6 to install any additional clock modules.

Step 8 Replace the front panel safety cover and power up the switch.

Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.

Step 9 Enter the show environment command to verify the status of the replaced module.

This example shows that the clock module is functioning properly:

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
