Cisco 7600 Series Ethernet Services Plus (ES+) and Ethernet Services Plus T (ES+T) Line Card Configuration Guide

Interpreting Console Error Messages

To view the explanations and recommended actions for Cisco 7600 series router error messages, including messages related to Cisco 7600 series router ES+ line cards, refer to the Cisco 7600 Series Cisco IOS System Message Guide, 12.2SR at http://www.cisco.com/en/US/docs/ios/system/messages/guide/consol_smg.html

Using debug Commands

Along with the other debug commands supported on the Cisco 7600 series router, you can obtain specific debug information for the ES+ line card on the Cisco 7600 series router using the debug hw-module privileged EXEC command.

The debug hw-module command is intended for use by Cisco technical support personnel.

Caution Because debugging output is assigned high priority in the CPU process, it can render the system unusable. For this reason, use debug commands only to troubleshoot specific problems or during troubleshooting sessions with Cisco technical support staff. Moreover, it is best to use debug commands during periods of lower network traffic and fewer users. Debugging during these periods decreases the likelihood that increased debug command processing overhead will affect system use.

For information about other debug commands supported on the Cisco 7600 series routers, refer to the Cisco IOS Debug Command Reference, Release 12.2 SR at http://www.cisco.com/en/US/docs/ios/12_2/debug/command/reference/122debug.html.

Using show Commands

There are several show commands that you can use to monitor and troubleshoot the ES+ line card on the Cisco 7600 series routers. For more information about show commands, see the Cisco IOS Release 12.2 SR Command References at http://www.cisco.com/en/US/products/ps6922/prod_command_reference_list.html .

Preparing for Online Removal of a Cisco 7600 Series ES+ Line Card

The Cisco 7600 series router supports OIR of the ES+ line card. To do this, you can power down an ES+ line card (which automatically deactivates any installed optical transceivers) and remove the ES+ line card still intact.

Although graceful deactivation of an ES+ line card is preferred using the no power enable module command, the Cisco 7600 series router does support removal of the ES+ line card without deactivating it first. If you plan to remove an ES+ line card, you can deactivate the ES+ line card first, using the no power enable module global configuration command. When you deactivate an ES+ line card using this command, it automatically deactivates each of the optical transceivers that are installed in that ES+ line card. Therefore, it is not necessary to deactivate each of the optical transceivers prior to deactivating the ES+ line card.

Either a blank filler plate or a functional optical transceiver should reside in every subslot of an ES+ line card during normal operation.

For more information about the recommended procedures for physical removal of the ES+ line card, refer to the Cisco 7600 Series Ethernet Services Plus Line Card Hardware Installation Guide.

Deactivating a Cisco 7600 Series ES+ Line Card

To deactivate an ES+ line card and its installed optical transceivers prior to removal of the line card, use the following command in global configuration mode:

For information on how to specify the physical locations of a ES+ line card on the Cisco 7600 series routers, see the Specifying the Slot Location for a Cisco 7600 Cisco 7600 Series ES+ Line Cards section in the Cisco 7600 Series Ethernet Services Plus Line Card Hardware Installation Guide.

Reactivating a Cisco 7600 Series ES+ Line Card

Once you deactivate a ES+ line card, whether or not you have performed an OIR, you must use the power enable module global configuration command to reactivate the ES+ line card.

If you did not issue a command to deactivate the optical transceivers installed in an ES+ line card, but you did deactivate the ES+ line card using the no power enable module command, then you do not need to reactivate the optical transceivers after an OIR of the ES+ line card. The installed optical transceivers automatically reactivate upon reactivation of the ES+ line card in the router.

For example, consider the case in which you remove an ES+ line card from the router to replace it with another ES+ line card. You reinstall the same optical transceivers into the new ES+ line card. When you enter the power enable module command on the router, the optical transceivers will automatically reactivate with the new ES+ line card.

To activate a ES+ line card and its installed optical transceivers after the ES+ line card has been deactivated, use the following command in global configuration mode:

For information on how to specify the physical locations of a ES+ line card on the Cisco 7600 series routers, see the Specifying the Slot Location for a Cisco 7600 Cisco 7600 Series ES+ Line Cards section in the Cisco 7600 Series Ethernet Services Plus Line Card Hardware Installation Guide.

Verifying Deactivation and Activation of a Cisco 7600 Series ES+ Line Card

To verify the deactivation of an ES+ line card, enter the show module command in privileged EXEC configuration mode. Observe the Status field associated with the ES+ line card that you want to verify.

The following example shows that the ES+ line card located in slot 10 is deactivated. This is indicated by its “PwrDown” status.

To verify activation and proper operation of an ES+ line card, enter the show module command and observe “Ok” in the Status field as shown in the following example:

For information on how to specify the physical locations of a ES+ line card on the Cisco 7600 series routers, see the Specifying the Slot Location for a Cisco 7600 Cisco 7600 Series ES+ Line Cards section in the Cisco 7600 Series Ethernet Services Plus Line Card Hardware Installation Guide.

Deactivation and Activation Configuration Examples

This section provides the following examples of deactivating and activating an ES+ line card and optical transceivers:

• Deactivation of a Cisco 7600 Series ES+ Line Card Configuration Example
• Activation of a Cisco 7600 Series ES+ Line Card Configuration Example

Deactivation of a Cisco 7600 Series ES+ Line Card Configuration Example

Deactivate an ES+ line card when you want to perform OIR of the ES+ line card. The following example deactivates the ES+ line card that is installed in slot 5 of the router, its optical transceivers, and all of the interfaces. The corresponding console messages are shown:

Activation of a Cisco 7600 Series ES+ Line Card Configuration Example

Activate an ES+ line card if you have previously deactivated it. If you did not deactivate the optical transceivers, the optical transceivers automatically reactivate with reactivation of the ES+ line card.
