Installing and Removing a SIP
This chapter describes how to install or remove SIPs on the Cisco 7600 series routers. This chapter contains the following sections:
Handling SIPs
Each SIP circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, read Chapter 4, "Preparing to Install a SIP or a Shared Port Adapter," for a list of parts and tools required for installation.
CautionAlways handle the SIP by the carrier edges and handle; never touch the SIP components or connector pins. (See Figure 5-1.)
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 SIP in a slot that is not in use, you must first remove the blank filler plate.
Figure 5-1 Handling a SIP
Online Insertion and Removal
The Cisco 7600 series router supports online insertion and removal (OIR) of the SPA interface processor (SIP) or SPA services card (SSC), in addition to each of the shared port adapters (SPAs). Therefore, you can remove a SIP or SSC with its SPAs still intact, or you can remove a SPA independently from the SIP or SSC, leaving the SIP or SSC installed in the router.

Note
Preparing for Online Removal of a SIP or SSC
The Cisco 7600 series router supports OIR of the SIP and the SSC. To do this, you can power down a SIP (which automatically deactivates any installed SPAs) and remove the SIP with the SPAs still intact.
Although graceful deactivation of a SIP is preferred using the no power enable module command, the Cisco 7600 series router does support removal of the SIP without deactivating it first. If you plan to remove a SIP, you can deactivate the SIP first, using the no power enable module global configuration command. When you deactivate a SIP using this command, it automatically deactivates each of the SPAs that are installed in that SIP. Therefore, it is not necessary to deactivate each of the SPAs prior to deactivating the SIP.
Either a blank filler plate or a functional SPA should reside in every subslot of a SIP during normal operation.
For more information about the recommended procedures for physical removal of the SIP, refer to the Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide.
Deactivating a SIP or SSC
To deactivate a SIP or SSC and its installed SPAs prior to removal of the SIP, use the following command in global configuration mode:
For more information about chassis slot numbering, refer to the "Identifying Slots and Subslots for SIPs, SSCs, and SPAs" section in this guide.
Reactivating a SIP or SSC
Once you deactivate a SIP or SSC, whether or not you have performed an OIR, you must use the power enable module global configuration command to reactivate the SIP.
If you did not issue a command to deactivate the SPAs installed in a SIP, but you did deactivate the SIP using the no power enable module command, then you do not need to reactivate the SPAs after an OIR of the SIP. The installed SPAs automatically reactivate upon reactivation of the SIP in the router.
For example, consider the case where you remove a SIP from the router to replace it with another SIP. You reinstall the same SPAs into the new SIP. When you enter the power enable module command on the router, the SPAs will automatically reactivate with the new SIP.
To activate a SIP and its installed SPAs after the SIP has been deactivated, use the following command in global configuration mode:
Router(config)# power enable module slot
Activates the SIP in the specified slot and its installed SPAs, where:

For more information about chassis slot numbering, refer to the "Identifying Slots and Subslots for SIPs, SSCs, and SPAs" section in this guide.
Verifying Deactivation and Activation of a SIP or SSC
To verify the deactivation of a SIP or SSC, enter the show module command in privileged EXEC configuration mode. Observe the Status field associated with the SIP that you want to verify.
The following example shows that the Cisco 7600 SIP-400 located in slot 13 is deactivated. This is indicated by its "PwrDown" status.

The Cisco 7600 series router supports OIR of a SPA independently of removing the SIP or SSC. This means that a SIP can remain installed in the router with one SPA remaining active, while you remove another SPA from one of the SIP subslots. If you are not planning to immediately replace a SPA into the SIP, then be sure to install a blank filler plate in the subslot. The SIP should always be fully installed with either functional SPAs or blank filler plates.
The interface configuration is retained (recalled) if a SIP or SPA is removed and then replaced with one of the same type. This is not the case if you replace a Cisco 7600 SIP-200 with a Cisco 7600 SIP-400 or vice versa.
If you are planning to remove a SIP along with its SPAs, then you do not need to follow the instructions in this section. To remove a SIP, see the "Preparing for Online Removal of a SIP or SSC" section.
Note
Deactivating a SPA
Although graceful deactivation of a SPA is preferred using the hw-module subslot shutdown command, the Cisco 7600 series router does support removal of the SPA without deactivating it first. Before deactivating a SPA, ensure that the SIP is seated securely into the slot before pulling out the SPA itself.
Note
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following command in global configuration mode:
For more information about chassis slot and SIP subslot numbering, refer to the "Identifying Slots and Subslots for SIPs, SSCs, and SPAs" section in this guide.
Reactivating a SPA
Note
If you deactivate a SPA using the hw-module subslot shutdown global configuration command and need to reactivate it without performing an OIR, you need to use the no hw-module subslot shutdown global configuration command to reactivate the SPA and its interfaces.
To activate a SPA and its interfaces after the SPA has been deactivated, use the following command in global configuration mode:
Verifying Deactivation and Activation of a SPA
When you deactivate a SPA, the corresponding interfaces are also deactivated. This means that these interfaces will no longer appear in the output of the show interface command.
To verify the deactivation of a SPA, enter the show hw-module subslot all oir command in privileged EXEC configuration mode. Observe the Operational Status field associated with the SPA that you want to verify.
In the following example, the SPA located in subslot 1 of the SIP in slot 2 of the router is administratively down from the hw-module subslot shutdown command:
Router# show hw-module subslot all oirModule Model Operational Status-------------- ------------------ -------------------------subslot 2/0 SPA-4XOC3-POS oksubslot 2/1 SPA-4XOC3-ATM admin downTo verify activation and proper operation of a SPA, enter the show hw-module subslot all oir command and observe "ok" in the Operational Status field as shown in the following example:
Router# show hw-module subslot all oirModule Model Operational Status-------------- ------------------ -------------------------subslot 2/0 SPA-4XOC3-POS oksubslot 2/1 SPA-4XOC3-ATM okDeactivation and Activation Configuration Examples

Deactivation of a SIP Configuration Example
Deactivate a SIP when you want to perform OIR of the SIP. The following example deactivates the SIP that is installed in slot 5 of the router, its SPAs, and all of the interfaces. The corresponding console messages are shown:
Router# configure terminalRouter(config)# no power enable module 51w4d: %OIR-6-REMCARD: Card removed from slot 5, interfaces disabled1w4d: %C6KPWR-SP-4-DISABLED: power to module in slot 5 set off (admin request)Activation of a SIP Configuration Example
Activate a SIP if you have previously deactivated it. If you did not deactivate the SPAs, the SPAs automatically reactivate with reactivation of the SIP.
The following example activates the SIP that is installed in slot 5 of the router, its SPA, and all of the interfaces (as long as the hw-module subslot shutdown command was not issued to also deactivate the SPA):Router# configure terminalRouter(config)# power enable module 5Notice that there are no corresponding console messages shown with activation. If you re-enter the power enable module command, a message is displayed indicating that the module is already enabled:Router(config)# power enable module 5% module is already enabledDeactivation of a SPA Configuration Example
Deactivate a SPA when you want to perform OIR of that SPA. The following example deactivates the SPA (and its interfaces) that is installed in subslot 0 of the SIP located in slot 2 of the router and removes power to the SPA. Notice that no corresponding console messages are shown:
Router# configure terminal
Router(config)# hw-module subslot 2/0 shutdown unpowered
Activation of a SPA Configuration Example
Activate a SPA if you have previously deactivated it. If you have not deactivated a SPA and its interfaces during OIR of a SIP, then the SPA is automatically reactivated upon reactivation of the SIP.
The following example activates the SPA that is installed in slot 2 of the router and all of its interfaces.Router# configure terminal
Router(config)# no hw-module subslot 2/0 shutdown
