Connecting Cisco Video Management and Storage System Network Modules

To connect Cisco Video Management and Storage System network modules to an external device, use a straight-through two-pair Category 5e unshielded twisted-pair (UTP) cable, and connect the RJ-45 Gigabit Ethernet port on the network module to a switch, hub, repeater, server, or other Gigabit Ethernet network device.

---

Note RJ-45 cables are not available from Cisco. These cables are widely available and must be Category 5e cables.

---

Connecting to an External Storage Device using iSCSI

The Cisco Video Management and Storage System enhanced network module supports an Internet SCSI (iSCSI) connection to an external storage device. The Gigabit Ethernet port on the faceplate of the network module and the Gigabit Ethernet port on the router can be configured as iSCSI connections.

To connect Cisco Video Management and Storage System enhanced network modules to an external storage device using iSCSI:

•Use a straight-through two-pair Category 5e unshielded twisted-pair (UTP) cable to connect the Cisco Video Management and Storage module to a switch.

•Use a straight-through two-pair Category 5e unshielded twisted-pair (UTP) cable to connect to an iSCSI device to a switch.

•Use a crossover two-pair Category 5e unshielded twisted-pair (UTP) cable to connect the Cisco Video Management and Storage module to an iSCSI device.

---

Note RJ-45 cables are not available from Cisco. These cables are widely available and must be Category 5e cables.

---

For details about configuring iSCSI connections, see the Cisco Video Management and Storage System 1.0 CLI Administrator Guide.

Establishing a Gigabit Ethernet Internal Connection

Use the Cisco High-Speed Intrachassis Module Interconnect (HIMI) feature to establish a Gigabit Ethernet internal logical connection between two network modules, or between an onboard small-form-factor pluggable (SFP) Gigabit Ethernet module and a network module on a Cisco 3825 router or a Cisco 3845 router.

Connections can be established only as follows:

•Between the Gigabit Ethernet port in an installed onboard SFP module on the Cisco 3825 router or Cisco 3845 router

•Between Gigabit Ethernet interfaces in network module slots 1 and 2 on a Cisco 3825 router

•Between Gigabit Ethernet interfaces in network module slots 2 and 4 on a Cisco 3845 router

---

Note A module interconnection between the Gigabit Ethernet port on an SFP module on a Cisco 3825 router or a Cisco 3845 router and a network module slot or a network module-to-network module cross-connection is permitted at any given time. However, both types of connections cannot be implemented at the same time.

---

---

Note Connections between the onboard Ethernet ports and network module slots are not supported.

---

For details about configuring High-Speed Intrachassis Module Interconnect (HIMI) connections, see the Cisco High-Speed Intrachassis Module Interconnect (HIMI) Configuration Guide on Cisco.com:

Online Insertion and Removal of Cisco Network Modules Procedure

Some Cisco routers allow you to replace network modules without switching off the router or affecting the operation of other interfaces. This feature is called online insertion and removal (OIR). OIR of a module provides uninterrupted operation to network users, maintains routing information, and ensures session preservation.

---

Caution Unlike other network modules, Cisco Video Management and Storage System enhanced network modules use hard disks. Online removal of network modules without proper shutdown can cause file system corruption and might render the disk unusable. You must shut down the operating system on the network module in an orderly way before removing or powering down the module.

---

---

Caution Cisco routers support OIR with identical modules only. If you remove a module, install in its place another module exactly like the one you removed. If you remove a 2-slot module (along with any installed WAN or voice interface cards), install another module and card combination exactly like the one you removed.

---

For a description of informational and error messages that may appear on the console during this procedure, see the hardware installation guide for your router.

Integrated Storage System Module

If your router contains an Integrated Storage System module, you need to make sure that any archives being sent from the Cisco Video Management and Storage module to the Integrated Storage System module are stopped.

Before performing online removal of a network module and insertion of a replacement of the Cisco Video Management and Storage module, complete the following steps to check whether or not archives are being sent to from the Cisco Video Management and Storage module to the Integrated Storage system module. If the archives are being sent, you need to stop the archiving process.

---

Step 1 From the Cisco Video Management and Storage module, use the show video-surveillance archive command to check whether there are active archives being sent to the Integrated Storage System module.

SE-module> show video-surveillance archive

Step 2 If archives are being sent to the Integrated Storage System module, stop the archiving process using the following command:

SE-module> video-surveillance task archive-stop media

Step 3 To verify that the archive process has stopped, use the following command:

SE-module> show video-surveillance archives

---

After verifying that there are no archives being sent to the Integrated Storage System module, complete the following steps in the router privileged EXEC mode to perform online removal of a network module and insertion of a replacement:

---

Step 1 Initiate a network module session by using the following command:

Router# service-module integrated-Service-Engine slot/unit session

Trying 10.10.10.1, 2065 ... Open

SE-Module> enable

SE-Module#

Step 2 Back up the configuration files, see Appendix A: Backing Up Files in the Cisco Video Management and Storage CLI Administrator Guide.

Step 3 Exit the network module session by pressing Control-Shift-6, followed by pressing x.

Step 4 On the router, clear the integrated-Service-Engine console session by using the following command:

Router# service-module integrated-Service-Engine slot/unit session clear

Step 5 Perform a graceful shutdown of the network module disk drive by using the following command:

Router# service-module integrated-Service-Engine slot/unit shutdown 

Step 6 Shut down the network module interface:

Router (config)# interface integrated-Service-Engine slot/unit

Router (config-if)# shutdown

Router (config-if)# exit

Step 7 Unplug all network interface cables from the network module.

Step 8 Loosen the two captive screws that are holding the network module in the chassis slot.

Step 9 Slide the network module out of the slot.

Step 10 Align the replacement network module with the guides in the chassis slot, and slide it gently into the slot.

---

Note If the router is not fully configured with network modules, make sure that blank panels fill the unoccupied chassis slots to provide proper airflow.

---

Step 11 Push the module into place until you feel its edge connector mate securely with the connector on the backplane.

Step 12 Reconnect the network interface cables that you removed in Step 7.

Step 13 Check that the network module LEDs are on. This inspection ensures that connections are secure and that the new unit is operational.

Step 14 Initiate a network module session by using the following command:

Router# service-module integrated-Service-Engine slot/unit session

Trying 10.10.10.1, 2129 ... Open

SE-Module> enable

SE-Module#

Step 15 Restore the configuration files, see Appendix B: Restoring Files in the Cisco Video Management and Storage CLI Administrator Guide.:

Step 16 Exit the network module session by pressing Control-Shift-6, followed by pressing x.

Step 17 If the switch-on-fail command option on the Cisco Video Management and Storage module is:

•Disabled—the sending of archives to the Integrated Storage System module is automatically resumed.

•Enabled—archives are sent to the local disk drive of the Cisco Video Management and Storage module.

Step 18 On the router, clear the network module session by using the following command:

Router# service-module integrated-Service-Engine slot/unit session clear
