• Removing VISM and VISM-PR Front and Back Cards

• Applying Power to the VISM/VISM-PR Card

You can install VISM/VISM-PR cards in the following combinations:

•Install a VISM/VISM-PR front card and a back card as a pair. The front and back cards must occupy the same slot.

•Install a VISM/VISM-PR front card with no back card. The MGX 8000 Series bulk distribution feature allows this configuration. The Service Resource Module (SRM) and the MGX 8000 Series distribution bus provide access to the TDM lines.

Note VISM/VISM-PR cards in bulk distribution mode do not require back cards.

•Install a VISM/VISM-PR front card as a redundant card with a redundant back card in the same slot.

Note VISM/VISM-PR T1 front cards require T1 back cards, and E1 front cards require E1 back cards. Ensure that your configuration meets this requirement.

In each of these configurations, connections to the packet network are made through the MGX 8000 Series cellbus and an OC-3 port located on the MGX 8000 Series PXM card. For more information on front and back cards, see "Card Characteristics" in the Overview of the VISM and VISM-PR Cards section.

Overview of VISM and VISM-PR Cards in MGX 8000 Series Chassis

This section contains general guidelines for installing the VISM and VISM-PR cards in an MGX 8000 Series chassis.

Installing VISM/VISM-PR Cards in an MGX 8850 and MGX 8250 Chassis

VISM and VISM-PR card installation in a Cisco MGX 8850 (PXM1 and PXM45) or a Cisco MGX 8250 platform consists of installing one front card and one back card (without the bulk distribution feature) in either the upper or lower shelf of the chassis.

You can use slots 1 to 6, 9 to 14, 17 to 22, and 25 to 30 to install VISM/VISM-PR cards (see Figure 4-1).

Note With PXM1 and SRM-3T3/C, bulk distribution is not supported in slots 9,10,15, and 26.

Figure 4-1 Available Chassis Slots for VISM Cards in the MGX 8850 and MGX 8250—Front View

Note If you use all of the available slots, you can configure the Cisco MGX 8850 and Cisco MGX 8250 with up to 24 VISM/VISM-PR cards. However, the two lower shelf cell buses can each sustain a bandwidth of one OC-3/STM-1 link. This bandwidth limits the number of E1 ports on the lower shelf to 39 in each half when you are using the G.711 codec. The number of VISM/VISM-PR cards is limited to 10.

For information about MGX 8250 and MGX 8850 hardware installation, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Hardware Installation Guide, Releases 2 Through 5.1.

Installing VISM/VISM-PR Cards in an MGX 8230 and MGX 8830 Chassis

VISM/VISM-PR card installation in a Cisco MGX 8230 platform and VISM-PR card installation in a Cisco MGX 8830 platform consist of installing one front card and one back card (if you are not using the bulk distribution feature) in either a left or right shelf slot.

You can use slots 3 to 6 and 10 to 13 to install VISM/VISM-PR cards (see Figure 4-2 for an example of VISM cards in an MGX 8230). If you use all the available slots, you can configure the Cisco MGX 8230 or Cisco MGX 8830 with up to eight VISM cards.

Installing VISM and VISM-PR Front and Back Cards

This section describes the following hardware installation procedures:

1. Installing a VISM or VISM-PR Front Card

2. Installing a VISM or VISM-PR Back Card

3. Connecting Cables to Cards

Installing a VISM or VISM-PR Front Card

Complete the following instructions to install a VISM or VISM-PR front card:

Step 1 Position the rear card guides over the appropriate slot in the chassis.

Step 2 Gently slide the card all the way into the slot and press the insertion/extractor lever until it snaps into a vertical or horizontal position.

Vertical is correct for the Cisco MGX 8250 or Cisco MGX 8850 (PXM1 and PXM45). Horizontal is correct for the Cisco MGX 8230 or Cisco MGX 8830.

Caution The card should slide in and out with only slight friction on the EMI gaskets on the adjacent board. Do not use force. Investigate any binding.

Installing a VISM or VISM-PR Back Card

Complete the following instructions to install a VISM or VISM-PR back card:

Step 1 Ensure that the two extractor levers are at the "in" or down position.

When you insert the card into the slot, ensure that the levers are parallel to the back card.

Step 2 Position the rear card guides over the appropriate slot in the chassis.

Step 3 Gently slide the card all the way into the slot.

Step 4 Tighten the two captive screws on the back card's faceplate.

Step 5 Tighten the upper and lower screws to prevent misalignment of the card.

Note Do not overtighten the screws. Tighten them only enough to secure the card.

Connecting Cables to Cards

After you install the VISM/VISM-PR front and back cards, connect the T1 or E1 cables to the RJ-48 or SMB connectors on the back cards. The T1 and E1 cables connect the eight ports on the back cards to the voice T1 or E1 lines. The T1 lines use RJ-48 connectors. The E1 lines use either RJ-48 or SMB connectors.

Cabling for RJ-48 Connectors on T1 and E1 Ports

T1 and E1 ports use RJ-48 connector wiring shown in Figure 4-3.

When you use the E1 VISM/VISM-PR back card with SMB cables, the E1 trunk cables connect the customer DSX-1 cross-connect point or E1 channel service unit (CSU) to the node. The connection is made with 75-ohm coaxial cable fitted with SMB connectors.

Removing VISM and VISM-PR Front and Back Cards

This section describes how to remove VISM/VISM-PR front and back cards and contains the following topics:

• Removing a VISM or VISM-PR Front Card

• Removing a VISM or VISM-PR Back Card

Removing a VISM or VISM-PR Front Card

To remove a VISM or VISM-PR front card, complete the following steps:

Step 1 Insert a small, flat-blade screwdriver into the slot in the insertion/extractor lever and press until the latch springs open, to approximately 10 degrees.

Step 2 Continue to lift the insertion/extractor lever to disconnect the connector.

Step 3 Gently pull the card out of the chassis.

Removing a VISM or VISM-PR Back Card

To remove a VISM or VISM-PR back card, complete the following steps:

Step 1 Remove any cables connected to the back card.

Step 2 Use a small, flat-blade screwdriver to unscrew the two retaining screws in the back card faceplate.

Step 3 Pull both of the extractor levers out to the horizontal position.

This action starts the removal of the card.

Step 4 Gently pull the card out of the chassis.

Applying Power to the VISM/VISM-PR Card

Apply power to a VISM/VISM-PR card by installing the card in an already running MGX 8000 Series platform. Alternatively, you can apply power to a chassis that has a previously installed VISM/VISM-PR card.

When power is applied, the VISM/VISM-PR card performs extensive testing and initialization functions. If the card has already been configured, the initialization downloads the configuration data from the disk on the PXM. This process takes approximately 2 minutes, during which the LED indicator blinks.

When the Active LED becomes solid green, the card is in the active state, is ready to be configured (if necessary), and is able to process data.

Upgrade Procedures

This section describes the following upgrade procedures:

• Prerequisites

• Check Domain Name Length

• VISM/VISM-PR Upgrades with PXM1

• VISM-PR Upgrades with PXM1E and PXM45

• VISM/VISM-PR Downgrade Procedure

• VISM to VISM-PR Hardware Upgrade

In Release 3.3, you can gracefully upgrade VISM/VISM-PR cards. A graceful upgrade preserves the existing configuration on the VISM/VISM-PR card throughout the upgrade procedure.

Caution Installing VISM software updates from VISM Release 2.2 with CALEA to VISM Release 3.3 without CALEA is not graceful.

Prerequisites

To ensure that the VISM/VISM-PR configuration is preserved throughout the upgrade procedure, you must complete the prerequisites listed here before you start the procedure:

•Configure your MGX 8000 Series shelf with at least two VISM cards in a redundant configuration.

For more information on adding redundancy, refer to the add redundancy (addred) command in the Cisco MGX 8250, Cisco MGX 8230, and Cisco MGX 8850 PXM1-based command reference documentation and in the Cisco MGX 8830 and Cisco MGX 8850 PXM1E/ PXM45-based command reference documentation.

•Ensure that the VISM cards are running at least Release 2.1 and that the VISM-PR cards are running at least Release 3.0.

•Download software Release 3.3 for VISM/VISM-PR to the MGX 8000 Series shelf.

•If you are using the CALEA feature, ensure that you have the version of VISM/VISM-PR software that supports CALEA.

•Delete all domain names that are greater than 32 characters on the VISM/VISM-PR card. See the "Check Domain Name Length" section.

Check Domain Name Length

Before you upgrade to Release 3.3, delete all domain names and domain name IPs that are greater than 32 characters on the VISM/VISM-PR card. After the upgrade, readd the domain names and domain name IPs.

Complete the following steps:

Step 1 Log in to the VISM/VISM-PR card.

Step 2 Display the list of domain names by entering the dspdns command. The following example shows sample domain names.

nodename.1.11.VISM8.a > dspdns

DomainNumber DomainName ResolutionType
------------ -------------- --------------
1 mga-SOLSYS1CA.234567890987654321234567890123456789.sol.cisco.com internalOnly

3 mga-SOLSYS1CA.234567890987654321234567890123456789.sol.cisco.eom internalOnly

Step 3 For each domain number, count the number of characters in the DomainName field.

If the characters are greater than 32 for each domain number, go to Step 4.

Step 4 Check for the IP addresses associated with the domain names by entering the dspdnallips command.

nodename.1.11.VISM8.a > dspdnallips

ResolutionIndex DomainName IP State Pref
--------------- ------------ ------------ --------- -----

Step 5 If IP addresses are present, make a note of them in the order that they appear.

Step 6 Since you cannot delete the domain name or domain name IPs if MGCs exist, use the following commands to check for MGCs.

a. Check for the MGC group protocols by entering the dspmgcgrpprotocols command.

nodename.1.11.VISM8.a > dspmgcgrpprotocols

MgcGrp Prot Qrntn Qrntn Sign Prov RspAck Disc Cancel

b. Check for MGC group entries by entering the dspmgcgrpparams command.

nodename.1.11.VISM8.a > dspmgcgrpparams

Mgc Grp Num Comm State State Chg Notification Priority
----------- ---------- ---------------------- --------
1 CommLoss Enabled 1

c. Check for MGC entries by entering the dspmgcs command.

nodename.1.11.VISM8.a > dspmgcs

mgcNumber mgcName
--------- -------
1 mga-SOLSYS1CA.234567890987654321234567890123456789.sol.cisco.com

Step 7 If any entries exist in Step 6, delete the MGC entries by entering the following commands:

•delmgcgrpprotocol

•delmggrpentry

•delmgc

Step 8 Delete the domain name IP address by entering the deldnip command.

Step 9 Delete the domain name by entering the deldn command.

Step 10 Perform the upgrade using the procedures in the "Upgrade VISM/VISM-PR Firmware with PXM1 Card" section or "Upgrade VISM-PR Firmware with PXM1E and PXM45 Cards" section.

Step 11 After you complete the upgrade, use the following commands to add the domain name entries, IP addresses, and MGCs as previously configured:

•adddn

•adddnip

•addmgc

•addmgcgrpentry

•addmgcgrpprotocol

Step 12 To check that you added the entries successfully, use the display commands in Step 2 to Step 6.

VISM/VISM-PR Upgrades with PXM1

This section describes the procedures for upgrading VISM/VISM-PR software when the VISM/VISM-PR is used with a PXM1 card.

Download VISM/VISM-PR Boot Code and Firmware to PXM1

To download the VISM/VISM-PR boot code and firmware to the PXM1 card, use TFTP.

Step 1 Log in to your TFTP server.

Step 2 Download the bootcode and firmware images from the Cisco website.

Step 3 Download the selected revision of service module boot code into the service module.

a. tftp <node_name or IP address>

b. bin

c. put <backup boot> POPEYE@SM_1_0.BT

d. quit

Step 4 Download the selected firmware file.

a. tftp <node_name or IP address>

b. bin

c. To upgrade all VISM cards:

put <FW file> POPEYE@SM_1_0.FW

quit

d. To upgrade an individual VISM card

put <FW file> POPEYE@SM_1_<slot number of card to upgrade>.FW

quit

Note Do not enter two put commands in the same TFTP session.

Step 5 Proceed to the "Upgrade VISM/VISM-PR Firmware with PXM1 Card" section to install the download.

Upgrade Boot Code with PXM1 Cards

Complete the following steps to upgrade the new backup boot code when you are using PXM1 cards in in a Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 chassis.

Step 1 Log in to the active PXM1 card (slot 7 or 8 for Cisco MGX 8250 and Cisco MGX 8850 chassis; slot 1 or 2 for Cisco MGX 8230 and Cisco MGX 8830 chassis).

Note VISM/VISM-PR must be in the active state in order for you to update the VISM/VISM-PR boot code.

Step 2 Execute the PXM1 install command.

nodename.1.27.VISM8.a > install [bt] [sm <slot>] <version>

Caution Do not touch the VISM/VISM-PR card until the status comes back ("Sent xxx bytes in yyy seconds"). Failure to follow this recommendation corrupts the boot code, which cannot be recovered.

When the boot code is being written to PROM, you see comments displayed at the VISM/VISM-PR prompt. This behavior is normal and expected.

Step 3 Type the version command to verify the correct boot code.

Note Step 3 is optional.

Upgrade VISM/VISM-PR Firmware with PXM1 Card

Release 3.3 firmware is for VISM and VISM-PR cards. Ensure that the VISM and VISM-PR cards have the minimum boot code version that is required for this release.

For a list of the boot code and firmware requirements, refer to the VISM/VISM-PR Release Notes located on Cisco.com.

In this procedure the following conditions apply:

•If two VISM or VISM-PR cards are part of a redundancy group, initially the primary card is in the active state, and the secondary card is in the standby state.

•Old-rev refers to the firmware prior to this release.

•New-rev refers to the firmware after the upgrade.

Perform the firmware upgrade on the VISM or VISM-PR cards. Do not remove the VISM cards and replace them with VISM-PR cards at this time.

Step 1 Log in to the active PXM1 card (slot 7 or 8 for Cisco MGX 8250 and Cisco MGX 8850 chassis; slot 1 or 2 for Cisco MGX 8230 and Cisco MGX 8830 chassis).

Step 2 Save the existing configuration by entering the savesmcnf command:

nodename.1.8.PXM.a > savesmcnf <SM slot#>

This command saves the existing configuration in the C:CNF directory. This file can be used during the downgrade procedure.

Step 3 To obtain the correct version of VISM/VISM-PR firmware, enter the dspfwrevs command.

The dspfwrevs command shows the firmware and boot code that is loaded on the chassis.

nodename.1.8.PXM.a > dspfwrevs

Step 4 Execute the PXM install command.

nodename.1.8.PXM.a > install sm <SM slot#> <new-rev>

Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.

Replace <new-rev > with the version of the new firmware.

The install command causes the secondary VISM or VISM-PR card to reset and come up in the standby state, running the new-rev firmware. The primary VISM or VISM-PR card is unaffected by this command.

Caution Ensure that you perform Step 4. If you do not perform Step 4, the boot code is corrupted and not recoverable.

Step 5 Execute the PXM newrev command.

nodename.1.8.PXM.a > newrev sm <SM slot#> <new-rev>

Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.

Replace <new-rev> with the version of the new firmware.

The newrev command causes the primary VISM or VISM-PR card to reset. The secondary VISM or VISM-PR card becomes active and runs the new-rev firmware.

Step 6 Execute the PXM commit command.

nodename.1.8.PXM.a > commit sm <SM slot#> <new-rev>

Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.

Replace <new-rev> with the version of the new firmware.

The two VISM or VISM-PR cards are now back to their original condition, except that both cards are now running the new-rev firmware.

Step 7 Log in to the active VISM or VISM-PR card and use the display commands (for example, dspendpts, dspcasvar, and so forth) to confirm that the configuration has been preserved through the upgrade process.

For more than one primary VISM or VISM-PR card in a redundancy group, ensure that the secondary card is in the standby state, and repeat Step 5 and Step 6 for each VISM/VISM-PR card in the redundancy group.

If the VISM or VISM-PR card is not part of a redundancy group, complete only Step 1 to Step 4.

VISM-PR Upgrades with PXM1E and PXM45

This section describes the procedures for upgrading VISM-PR software when the VISM-PR is used with a PXM1E or PXM45 card.

For upgrade notes regarding specific releases, refer to the VISM/VISM-PR Release Notes located on Cisco.com.

Download VISM-PR Boot Code and Firmware to PXM1E and PXM45

To download the VISM-PR boot code and firmware to the PXM1E or PXM45 card, use FTP.

Step 1 Access the bootcode and firmware images on Cisco.com.

Step 2 To download the images, enter the ftp command.

ftp node-ip

The node-ip argument is the IP address of the node to which you want to download the image.

Step 3 Enter your user name and password.

Step 4 Enter bin.

Step 5 Change to the C:FW directory.

cd C:FW

Step 6 Download the images to your C:FW directory.

a. To download one file at a time, use the put image-version command.

b. To download multiple files at the same time, use the mput <image-version> <image-version> command.

The image-version argument is the image that you accessed in Step 1.

Step 7 To exit the download procedure, enter bye.

Upgrade Boot Code with PXM1E and PXM45 Cards

Complete the following steps to upgrade the new backup boot code when you are using PXM1E or PXM45 cards in your MGX 8000 Series chassis:

Step 1 Complete the steps in the "Download VISM-PR Boot Code and Firmware to PXM1E and PXM45" section.

Step 2 Log in to the active PXM1E or PXM45 card.

Step 3 To upgrade the VISM-PR boot, enter the burnboot command.

nodename.1.7.PXM.a > burnboot <slot> <revision>

Replace <slot> with the number of the VISM-PR card that you want to upgrade.

Replace <revision> with the version of the bootcode you downloaded from Step 1.

The following example shows sample results from the burnboot command.

nodename.1.7.PXM.a > burnboot 12 3.2(0.0)

The card in slot 12 will be reset.
burnboot:Do you want to proceed (Yes/No)? yes

For VISM-PR cards without redundancy, the card automatically resets and becomes active with the latest boot code image.

For VISM-PR cards with redundancy, the active card takes approximately 60 seconds to reset as standby. For the original standby card, complete Step 2- Step 3. This card now resets and becomes the standby again, and the standby card is now active.

Upgrade VISM-PR Firmware with PXM1E and PXM45 Cards

Complete the steps in this section to upgrade the VISM-PR firmware. Ensure that the VISM-PR cards have the minimum boot code version.

For a list of the boot code and firmware requirements, refer to the VISM/VISM-PR Release Notes located on Cisco.com.

Caution If you plan to upgrade PXM cards and VISM-PR modules, upgrade the PXM cards first. Wait until the PXM cards are operating in active and standby modes with the correct software before upgrading the VISM-PR modules. Failing to upgrade the node in the correct order can fail VISM connections, causing significant service disruption.

Perform the firmware upgrade on the VISM-PR cards.

Step 1 Log in to the active PXM1E or PXM45 card.

Step 2 Ensure that the card is in the redundant mode, where the active card is the primary card.

Step 3 To save the existing configuration, enter the saveallcnf command.

nodename.1.7.PXM.a > saveallcnf

Step 4 To load the new software, enter the loadrev command.

nodename.1.7.PXM.a > loadrev <sm-primary-slot-num> <new-rev>

Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.

Replace <new-rev> with the new firmware version number for the VISM-PR software.

Caution Temporary traffic loss occurs.

Step 5 Ensure that the redundant card is returned to the standby state by executing the dspcds command.

Note You must wait for the redundant card to return to the standby state. If you issue the runrev command too early, an error message is generated. The rev change does not occur.

Step 6 To execute the download, enter the runrev command.

nodename.1.7.PXM.a > runrev <sm-primary-slot-num> <new-rev>

Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.

Replace <new-rev> with the new firmware version number for the VISM-PR software.

Caution Temporary traffic loss occurs.

Step 7 Ensure that the primary card completes booting up and goes into the standby state by executing the dspcds command.

Note You must wait for the primary card to finish booting up and get to standby state. Issuing the commitrev command early might be accepted without an error. However, the active and standby cards might not be swapped back to their original states. For example, the original primary card might be left in standby, and the original redundant card might be left as active.

Step 8 After the new release is running successfully, commit the new download to the VISM-PR card by entering the commitrev command.

nodename.1.7.PXM.a > commitrev <sm-primary-slot-num> <new-rev>

Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.

Replace <new-rev> with the new firmware version number for the VISM-PR software.

The commitrev command switches the primary card from a standby state to an active state and the redundant card from an active state back to a standby state.

Step 9 To verify the card states, enter the dspcds command.

VISM/VISM-PR Downgrade Procedure

Use this procedure to downgrade VISM/VISM-PR software from the current release to an earlier VISM/VISM-PR release. If you use the downgrade procedure described here, you can retain the configurations after the downgrade.

Note The configurations that existed with old-rev firmware should have been saved earlier. You cannot downgrade from VISM-PR to VISM.

Complete the following steps to downgrade the VISM/VISM-PR software:

Step 1 If the VISM/VISM-PR card is in a redundancy group, remove the redundancy.

nodename.1.7.PXM.a > delred <SM slot#>

Step 2 Download the old-rev firmware onto the MGX shelf using the firmware download procedures in the "Download VISM/VISM-PR Boot Code and Firmware to PXM1" section or the "Download VISM-PR Boot Code and Firmware to PXM1E and PXM45" section.

Step 3 Execute the PXM clrsmcnf command.

nodename.1.7.PXM.a > clrsmcnf <SM slot#>

Replace <SM slot#> with the slot number of the VISM/VISM-PR card to be downgraded.

Wait for the card to become active. The VISM/VISM-PR card resets after you execute this command.

Step 4 For PXM1 cards, execute the PXM1 restoresmcnf command.

nodename.1.7.PXM.a > restoresmcnf -f <filename> -s <SM slot#>

Replace <filename> with the name of the old configuration file that was saved while the old-rev firmware was running. The file can be found in the C:CNF directory on the MGX shelf.

Replace <SM slot#> with the slot number of the VISM/VISM-PR card to be downgraded.

The VISM/VISM-PR card resets again. The card becomes active, running the old-rev firmware with the old configuration.

Step 5 For PXM1E/PXM45 cards, save and restore the configuration of all cards in a chassis using the saveallcnf and restoreallcnf commands.

Note For PXM1E/PXM45 cards, you cannot restore the configuration for an individual VISM-PR service module.

Caution The restoreallcnf command reconfigures all of the cards in the chassis.

Reconfigure the redundancy group, if required.

VISM to VISM-PR Hardware Upgrade

Complete the following steps to upgrade your system from VISM cards to VISM-PR cards.

Caution For this procedure, you must install the redundant (standby) VISM-PR card first. Failure to follow this recommendation results in traffic loss. In addition, do not remove an active VISM card from your chassis. Ensure that you change an active VISM card to the standby state before you remove it and replace it with a VISM-PR card.

Step 1 Remove the redundant (standby) VISM card from its slot in your chassis.

Step 2 Install a VISM-PR card in the same slot.

Step 3 Administratively configure the VISM-PR card you installed in Step 2 as primary (active).

Step 4 Remove the now redundant VISM card from your chassis.

Step 5 Install a VISM-PR card in the slot from which you removed the VISM card in Step 4.

Step 6 Log in to the redundant (secondary) VISM-PR card and execute the dspcd command. Verify that the output from the dspcd command lists the card type under FunctionModuleType as a VISM-PR card. If the card type still indicates the VISM card, execute the resetcd slot-num command from the PXM and repeat the dspcd command to ensure that the correct card type is shown.

Step 7 Log in to the active VISM-PR card and execute the dspcd command. Verify that the output from the dspcd command lists the card type under FunctionModuleType as a VISM-PR card.

If the card type still indicates the VISM card, execute the resetcd slot-num command from the PXM. Repeat the dspcd command to ensure that the correct card type is shown.

Step 8 If you have no other VISM cards in your chassis, you have completed the hardware upgrade procedure; do not proceed to Step 9. If you have more VISM cards in your chassis, proceed to Step 9.

Step 9 Remove a standby VISM card from its slot in your chassis.

Step 10 Install a VISM-PR card in the same slot.

Step 11 Repeat Step 9 and Step 10 to remove any remaining VISM cards in your chassis and replace them with VISM-PR cards.

Step 12 Repeat Step 6 and Step 7 on the remaining VISM-PR cards to ensure that the correct card type is shown for each.
