Basic Workflow for Installing the Cisco SRE Service Module into the Router

1. Verify that the router, the Cisco SRE Service Module, and the Cisco IOS software version that is installed on the router are compatible. See the "Verifying the Router, Cisco SRE Service Module, and Cisco IOS Software Version Compatibility" section.

2. Install the Cisco SRE Service Module into the router. See the "Installing the Cisco SRE Service Module into the Router" section.

3. Verify that the Cisco SRE Service Module is correctly detected by the router. See the "Verifying Cisco SRE Service Module Installation" section

Verifying the Router, Cisco SRE Service Module, and Cisco IOS Software Version Compatibility

Table 2-1 provides the compatibility between the routers, Cisco SRE Service Modules, and the
Cisco IOS software version that you must install on the router to use Cisco SRE-V.

Installing the Cisco SRE Service Module into the Router

To install the Cisco SRE Service Module into the Cisco 2900 series or 3900 series ISR G2, see Figure 2-1. For detailed information, see Installing Cisco Network Modules and Service Modules in Cisco Access Routers on Cisco.com.

Verifying Cisco SRE Service Module Installation

After the Cisco SRE Service Module is physically installed in a Cisco router, and the router is loaded with a compatible Cisco IOS image and powered back on, do the following to ensure that the Cisco SRE Service Module is correctly detected by the router.

To verify the Cisco SRE Service Module installation, complete the following steps:


Step 1 Verify that the router detects the presence of the newly installed Cisco SRE Service Module. From the router, enter enable mode, and then use the show diag | include FRU command. The Field Replaceable Unit (FRU) details are displayed, as shown in the following example of a Cisco SRE 900 Service Module:

Router# show diag | include FRU
		Product (FRU) Number     : CISCO2951/K9
		Product (FRU) Number     : PWR-2921-51-POE
		Product (FRU) Number     : PVDM3-32       
		Product (FRU) Number     : SM-SRE-900-K9

Step 2 Use the show hardware command to verify that the router recognizes the service module.

Online Insertion and Removal of the Cisco SRE Service Module

The Cisco 3900 series ISR G2 supports the Online Insertion and Removal (OIR), or hot swap, of the
Cisco SRE Service Module.

The Cisco 2900 series ISR G2 does not support OIR of the Cisco SRE Service Module. To install or remove the Cisco SRE Service Module from the Cisco 2900 series ISR G2, make sure that you first power down the router, and then install or remove the Cisco SRE Service Module.

To perform OIR of a Cisco SRE Service Module from a Cisco 3900 series ISR G2, complete the following steps:

SUMMARY STEPS

1. service-module sm slot/0 shutdown

2. service-module sm slot/0 status

3. hw-module sm 1 oir-stop

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

service-module sm slot/0 shutdown

Example:

Router# service-module sm 1/0 shutdown

Shuts down the Cisco SRE Service Module system gracefully. Use this command when removing or replacing a hot-swappable module during OIR.

If the virtual machines on the VMware vSphere HypervisorTM have VMware tools installed on them, and you issue this command, the virtual machines shut down first, and then the Cisco SRE Service Module shuts down.

If the virtual machines do not have VMware tools installed on them, and you issue this command, the virtual machines get powered off first, and then the shutdown signal is sent to the service module. After about two minutes, the Cisco SRE Service Module shuts down.

Step 2 

service-module sm slot/0 status

Example:

Router# service-module sm 1/0 status

Verifies whether the Cisco SRE Service Module system is in the shut down state.

Step 3 

hw-module sm 1 oir-stop

Example:

Router# hw-module sm 1 oir-stop

Removes the Cisco SRE Service Module from the router.

When you enter this command, OIR messages are displayed. After the messages finish displaying, remove the Cisco SRE Service Module from the router.
