Installing VISM/VISM-PR Hardware and Software

This section describes how to install VISM/VISM-PR cards and how to upgrade the VISM/VISM-PR boot code and firmware. The following topics are described:

• Hardware Installation

• Software Upgrades

Hardware Installation

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. Access to and from the TDM lines is performed by the Service Resource Module (SRM) and the MGX 8000 Series distribution bus.

Note VISM 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. See the "Card Physical Characteristics" section on page 2-5 for more information on front and back cards.

VISM Cards in MGX 8000 Series Chassis

VISM front and back cards can be installed in the MGX 8000 Series platforms with the following basic guidelines:

•Cisco MGX 8850 (PXM1)—Up to 24 slots can be used for VISM cards.

•Cisco MGX 8250—Up to 24 slots can be used for VISM cards.

•Cisco MGX 8230—Up to eight slots can be used for VISM cards.

The VISM card can be used with the PXM1 processor module.

VISM-PR Cards in MGX 8000 Series Chassis

VISM-PR front and back cards can be installed in the MGX 8000 Series platforms with the following basic guidelines:

•MGX 8250 and MGX 8850 (PXM1 and PXM45)—Up to 24 slots can be used for VISM-PR cards.

•MGX 8230—Up to eight slots can be used for VISM-PR cards.

•MGX 8830—Up to eight slots can be used for VISM-PR cards.

The VISM-PR card can be used with the following processor modules:

•PXM1E

•PXM45

You must install an additional fan tray spacer at the bottom of your MGX 8000 Series switch chassis directly above the intake plenum if you are using the VISM-PR card in combination with the PXM45 card.

Refer to the Cisco MGX 8850 (PXM45/PXM1E) Hardware Installation Guide for step-by-step instructions to install a fan tray.

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 (if not using 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 3-1).

Figure 3-1 Available Chassis Slots for VISM Cards in the MGX 8850 and MGX 8250—Front View

Note If you use all 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 cellbuses 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 78 when using the G.711 code. The number of VISM/VISM-PR cards is limited to 10.

MGX 8230 and MGX 8830 Chassis

VISM/VISM 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 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 3-2 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 the vertical, Cisco MGX 8250 or Cisco MGX 8850 (PXM1 and PXM45), or horizontal (Cisco MGX 8230 or Cisco MGX 8830) position.

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" position.

When you insert the card into the slot, the levers should be vertical or horizontal along the line of 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.

Note In all text references to cables, "transmit" refers to a cable used for data moving away from the VISM/VISM-PR card, and "receive" refers to a cable used for data moving toward the VISM/VISM-PR card.

Cabling for RJ-48 Connectors on T1 and E1 Ports

For T1 and E1 ports that connect through an RJ-48 connector, each connector has the following pins:

•Transmit TIP (TTIP) pin

•Transmit RING (TRNG) pin

•Receive TIP (RTIP) pin

•Receive RING (RRNG) pin

•Two pins for shielded ground

•Test RING (TEST-RNG P)

•Test TIP (TEST-TIP)

The connector wiring is shown in Figure 3-3.

Figure 3-3 RJ-48 PIN Connector

Cabling for SMB Connectors on E1 Ports

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 using 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�.

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. Or, 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 two minutes, during which the LED indicator blinks. When the Active LED becomes solid green, the card is in the Active state and is ready to be configured (if necessary) and is able to process data.

Software Upgrades

VISM/VISM-PR Release 3.2 provides a graceful upgrade procedure for the following releases:

•From VISM 1.5 to VISM 3.2

•From VISM 2.1 to VISM 3.2

•From VISM 2.2 to VISM 3.2

•From VISM 3.1(1) to VISM 3.2

•From VISM 3.1(2) to VISM 3.2

Caution Installing VISM software updates from VISM Release 2.2 with CALEA to VISM Release 3.2 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 in this section.

Before starting the graceful upgrade procedure, complete the following prerequisites:

•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 the Cisco MGX 8830 and MGX 8850 PXM1E/ PXM45-based Command Reference documentation.

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

•Download software Release 3.2 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.

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.

To upgrade all VISM cards, proceed to Step 4 c. To upgrade an individual VISM card, proceed to Step 4 d.

a. tftp <node_name or IP address>

b. bin

c. put <FW file> POPEYE@SM_1_0.FW

quit

d. 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.

Upgrade VISM/VISM-PR Firmware with PXM1 Card

Software Release 3.2 is for VISM and VISM-PR cards. Ensure that the VISM and VISM-PR cards have the minimum boot code version of vism_8t1e1_VI8_BT_3.2.00.fw.

The following versions of VISM software Release 3.2 are available:

•003.002.000.000—without CALEA

•003.052.000.000—with CALEA

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, Release 3.1(2) and prior.

•New-rev refers to the firmware after the upgrade, Release 3.2.

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).

Step 2 Save the existing configuration as a contingency plan by entering:

savesmcnf <SM slot#>

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

Step 3 Execute the PXM install command:

install sm <SM slot#> <new-rev>

where:

SM slot# is the slot number of the primary VISM or VISM-PR card and new-rev is the file name of the new firmware (for example, vism_8t1e1_003.002.000.000.fw).

This 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.

Step 4 Execute the PXM newrev command:

newrev sm <SM slot#> <new-rev>

where:

SM slot# is the slot number of the primary VISM or VISM-PR card and new-rev is the filename of the new firmware.

This command causes the primary VISM or VISM-PR card to reset and the secondary VISM or VISM-PR card to become active and running the new-rev firmware.

Step 5 Execute the PXM commit command:

commit sm <SM slot#> <new-rev>

where:

SM slot# is the slot number of the primary VISM or VISM-PR card and new-rev is the filename 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 6 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.

Note 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 4 and Step 5 for each VISM card in the redundancy group.

It is also recommended that you perform the following verifications:

•Make minor modifications to the configuration.

•Check that the changes have been executed correctly.

•Change the configuration back again.

Note If the VISM or VISM-PR card is not part of a redundancy group, complete Step 1 to Step 3.

For more information about the VISM and VISM-PR card specifications, see "VISM and VISM-PR Release 3.2 Specifications".

Boot Code Upgrade Procedure with PXM1 Cards

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

Note This procedure re-programs the VISM boot code for previous VISMs using the VISM runtime image version 1.0 to 2.0.

Step 1 Telnet to MGX shelf and cc to the VISM card.

Note VISM must be in the active state in order to update the VISM boot code.

Step 2 Access the server where the VISM boot code resides and TFTP the VISM boot code to the VISM card:

a. Type tftp <IP address of the MGX shelf>

b. Type bin at the tftp prompt.

Caution Ensure that you perform Step 2 b. If you to not perform Step 2 b. the boot code is corrupted and not recoverable.

c. Type install [bt] [sm <slot>] <version> at the PXM prompt.

Caution Do not touch the VISM 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 will see comments displayed at the VISM prompt. This behavior is normal and expected.

Step 3 Use the resetcd command for VISM from the PXM card for the latest boot take effect.

Step 4 Type the version command to verify the correct boot code.

Note Step 4 is optional.

You have completed upgrading the new VISM backup boot code.

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.

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 image on the Cisco Web site.

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

ftp node-ip

where node-ip 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 Access the appropriate directory.

cd C:FW

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

put image-version

where image-version is the downloaded image from Step 1.

Step 7 To exit the download procedure, enter bye.

Upgrade VISM-PR Firmware with PXM1E and PXM45 Cards

Ensure that the VISM-PR cards have the minimum boot code version of vism_8t1e1_VI8_BT_3.2.00.fw.

The following versions of VISM-PR software Release 3.2 are available:

•003.002.000.000—without CALEA

•003.052.000.000—with CALEA

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 as a contingency plan, enter the saveallcnf command.

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

loadrev sm-primary-slot-num new-rev

where sm-primary-slot-num is the slot number of the VISM-PR card in which you want to install the new software; and new-rev is the new firmware version number for the VISM-PR software.

Caution Temporary traffic loss occurs.

Step 5 To execute the download, enter the runrev command.

runrev sm-primary-slot-num new-rev

Caution Temporary traffic loss occurs.

Step 6 To commit the new download to the VISM-PR card, enter the commitrev command.

commitrev sm-primary-slot-num new-rev

You have completed the steps. Proceed to the Boot Code Upgrade Procedure with PXM1E and PXM45 Cards.

Boot Code Upgrade Procedure 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 VISM-PR Upgrades with PXM1E and PXM45.

Step 2 Log in to the PXM1E or PXM45 card.

Step 3 Use the burnboot sm-primary-slot-num new-rev command, where sm-primary-slot-num is the slot number of the VISM-PR card you want to upgrade and new-rev is the firmware version number of the new VISM software, to upgrade the VISM-PR boot code.

The VISM-PR card automatically resets and becomes active with the latest boot code image. You have completed the boot code upgrade procedure.

VISM/VISM-PR Downgrade Procedure

Use this procedure to downgrade VISM software from software Release 3.2 to an earlier VISM release. By following the downgrade procedure described here, the configurations are retained 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 software from software Release 3.2 for VISM/VISM-PR to Release 3.1.2, 2.2, 2.1, or 1.5:

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

delred <SM slot#>

Step 2 Download the old-rev firmware onto the MGX shelf.

Step 3 Execute the PXM clrsmcnf command:

clrsmcnf <SM slot#>

where:

SM slot# is the slot number of the VISM card to be downgraded.

The VISM card resets on executing this command. Wait for the card to come active.

Step 4 Execute the PXM restoresmcnf command:

restoresmcnf -f <filename> -s <SM slot#>

where:

The filename is 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.

The SM slot# is the slot number of the VISM card to be downgraded.

The VISM card resets again. When the card becomes active, it has the old-rev firmware running with the old configuration.

Step 5 Reconfigure 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 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 configure 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 your chassis.

Step 2 Install a VISM-PR card in the slot you removed the VISM card from in Step 1.

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 you removed the VISM card from 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 insure 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 and repeat the dspcd command to insure 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 your chassis.

Step 10 Install a VISM-PR card in the slot you removed the VISM card from in Step 9.

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 insure the correct card type is shown.
