Installing and Removing a Cisco 7600 Series Ethernet Services Plus Line Card
This chapter describes how to install or remove Cisco 7600 Series Ethernet Services + line cards on the Cisco 7600 series routers. This chapter contains the following sections:
Handling Cisco 7600 Series Ethernet Services Plus Line Cards
Each Cisco 7600 Series ES+ line card circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, read “Preparing to Install a Cisco 7600 Series Ethernet Services Plus Line Card,” for a list of parts and tools required for installation.
When a slot is not in use, a blank filler plate must be installed in the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed modules. If you plan to install a Cisco 7600 Series ES+ line card in a slot that is not in use, you must first remove the blank filler plate.

Online Insertion and Removal
The Cisco 7600 series routers support online insertion and removal (OIR) of the Cisco 7600 Series ES+ line card, as well as OIR for the SFP or XFP modules. Therefore, you can remove a Cisco 7600 Series ES+ line card with its SFP or XFP modules still intact, or you can remove SFP or XFP modules independently from the Cisco 7600 Series ES+ line card, leaving the line card installed in the router.
Note
The 40 port versions (7600-ES+40G3C and 7600-ES+40G3CXL) require longer maintenance time for card replacement. The 40 port versions (7600-ES+40G3C and 7600-ES+40G3CXL) require longer maintenance time for card replacement.
This section includes the following topics on OIR support:

Preparing for Online Removal of a Cisco 7600 Series Ethernet Services Plus Line Card
The Cisco 7600 series routers support OIR of the Cisco 7600 Series ES+ line card. To do this, you can power down a Cisco 7600 Series ES+ line card (which automatically deactivates any installed SFP or XFP modules) and remove the Cisco 7600 Series ES+ line card with the SFP or XFP modules still intact.
Although graceful deactivation of a 7600 ES+ line card is preferred using the no power enable module command, the Cisco 7600 series routers do support removal of the 7600 ES+ line card without deactivating it first.
If you plan to remove a Cisco 7600 Series ES+ line card, you can deactivate the Cisco 7600 Series ES+ line card first, using the no power enable module global configuration command.
When you deactivate a Cisco 7600 Series ES+ line card using this command, it automatically deactivates each of the SFP or XFP modules that are installed in that Cisco 7600 Series ES+ line card. Therefore, it is not necessary to deactivate each of the SFP or XFP modules prior to deactivating the Cisco 7600 Series ES+ line card.
Replacing a Cisco 7600 Series Ethernet Services Plus Line Card
1.
Capture the health of the steady state system running the target IOS and traffic snapshot.
2. Use the show run module command to display the running configuration of the module.
3. Save the running configuration to a file using the copy running-config tftp command. You are prompted to provide the address of the TFTP server and the file name.
4. Power down the old card using the no power enable module command.
5. Remove the old card from the slot and disconnect all cables. See Deactivating a Cisco 7600 Series Ethernet Services Plus Line Card.
6. Replace with a new card in the same slot and reconnect all the cables disconnected in the previous step, with a 1:1 port correspondence.
7. Enable power to the slot using the power enable module command. See Reactivating a Cisco 7600 Series Ethernet Services Plus Line Card.
8. Copy and paste the running configuration saved in Step 3 on the new card.
9. Enable all the interfaces using the no shut command in interface configuration mode.
10. Capture another health snapshot and compare these results with the results noted in Step 1.
11. Perform Stateful Switchover (SSO) to ensure proper working of HA.
12. Perform generic health check.
13. Perform SSO to restore active or standby roles as before.
Deactivating a Cisco 7600 Series Ethernet Services Plus Line Card
To deactivate a 7600 ES+ Ethernet line card and its installed SFPs or XFPs prior to removal of the 7600 ES+ line card, use the following command in global configuration mode:
|
|
|
|---|---|
Shuts down any installed interfaces, and deactivates the 7600 ES+ line card in the specified slot, where: |
For more information about chassis slot numbering, refer to the “Identifying Slots and Subslots for the Cisco 7600 Cisco 7600 Series ES+ Line Cards” section section in this guide.
Reactivating a Cisco 7600 Series Ethernet Services Plus Line Card
Once you deactivate a Cisco 7600 Series ES+ line card, whether or not you have performed an OIR, you must use the power enable module global configuration command to reactivate the Cisco 7600 Series ES+ line card.
If you did not issue a command to deactivate the SFP or XFP modules installed in a Cisco 7600 Series ES+ line card, but you did deactivate the Cisco 7600 Series ES+ line card using the no power enable module command, then you do not need to reactivate the SFP or XFP modules after an OIR of the Cisco 7600 Series ES+ line card. The installed SFP or XFP modules automatically reactivate upon reactivation of the Cisco 7600 Series ES+ line card in the router.
For example, consider the case where you remove a Cisco 7600 Series ES+ line card from the router to replace it with another Cisco 7600 Series ES+ line card. You reinstall the same SFP or XFP modules into the new Cisco 7600 Series ES+ line card. When you enter the power enable module command on the router, the SFP or XFP modules will automatically reactivate with the new Cisco 7600 Series ES+ line card.
To activate a Cisco 7600 Series ES+ line card and its installed SFP or XFP modules after the Cisco 7600 Series ES+ line card has been deactivated, use the following command in global configuration mode:
|
|
|
|---|---|
Activates the ES+ line card in the specified slot and its installed SFPs or XFPs, where: |
For more information about chassis slot numbering, refer to the Identifying Slots and Subslots for the Cisco 7600 Cisco 7600 Series ES+ Line Cards section in this guide.
Verifying Deactivation and Activation of a Cisco 7600 Series Ethernet Services Plus Line Card
To verify the deactivation of a 7600 ES+ line card, enter the show module command in privileged EXEC configuration mode. Observe the Status field associated with the 7600 ES+ line card that you want to verify.
The following example shows 7600 ES+ line cards located in slots 4 and 6. Slot 6 is powered down. This is indicated by its “PwrDown” status.
To verify activation and proper operation of a 7600 ES+ line card, enter the show module command and observe “Ok” in the Status field as shown in the following example:
Preparing for Online Removal of a SFP or XFP Modules
The Cisco 7600 series routers support OIR of a SFP or XFP modules independently of removing the Cisco 7600 Series ES+ line card. This means that a Cisco 7600 Series ES+ line card can remain installed in the router with one XFP remaining active, while you remove another XFP from one of the line card ports. Or, that an Cisco 7600 Series ES+ line card can remain installed in the router with some number of SFP modules remaining active, while you remove other SFP modules from the line card ports.
The interface configuration is retained (recalled) if a Cisco 7600 Series ES+ line card or SFP or XFP is removed and then replaced with one of the same type.
If you are planning to remove a Cisco 7600 Series ES+ line card along with its SFP or XFP modules, then you do not need to follow the instructions in this section. To remove a Cisco 7600 Series ES+ line card, see the “Preparing for Online Removal of a Cisco 7600 Series Ethernet Services Plus Line Card” section.
SFP Module or XFP Module OIR
The SFP and XFP modules support online insertion and removal (OIR). However, if the line card is already installed in the router and the system is operational, we recommend that you administratively shut down the SFP or XFP module port before installing a new module.
