Installing a VGMC (MC32)

Installing and Programming a 32 Port Media Gateway Card


Hardware: A0852632 ITG card adaptor

  1. Seat the MC32 VGMC card in a free slot. It's similar to a MIRAN card, but with 32 ports.
  2. Plug the ITG card adaptor (A0852632) into the corresponding card slot Amphenol.
  3. Run two patch cables from the RJ45 Jacks on the ITG card adaptor to the data switch.
    Note, the top RJ-45 connector is ELAN, the bottom RJ-45 is TLAN.

Software: Element Manager: New VGMC

  1. Log in to Element Manager.
  2. Select IP Telephony ► Configuration from the left menu
  3. From the Node Configuration screen, click Edit next to the Node ID
  4. Click on the ADD button, located next to the Cards option.
  5. Enter the following:
    1. ELAN IP address
    2. ELAN port MAC address, printed on the faceplate label
    3. TLAN IP address
    4. TLAN gateway IP address
    5. A Host Name, eg: VGMC_1
    6. The TN (l s c), where the card is located
    7. Hardware type, eg: Succession Media Card
  6. Click Save and Transfer, and click OK
    The transfer process begins. It will fail - but don't worry!
  7. Press the faceplate reset button, and wait for the card to reboot.
  8. Click Save and Transfer again.
    If successful, the configuration will transfer to the card.

Note: If this is a new card, you will need to build the Voice Gateway Channels in LD 14.

Replacing a 32 Port Media Gateway Card

  1. Log into PBX, and enter LD 32
  2. STAT l s c u. If the card is enabled, disable it with DISC l s c u
  3. Remove the old MC32 card, and install the new MC32 card
  4. Log into Element Manager, and go to Node edit area where the card is. Open that cards info.
  5. Enter the ELAN mac address of the replacement card, printed on the faceplate label.
  6. Click Save and Transfer, and click OK
    The transfer process begins. It will fail - but don't worry!
  7. Press the faceplate reset button, and wait for the card to reboot.
  8. Click Save and Transfer again.
    If successful, the configuration will transfer to the card.
  9. Enable the card in LD 32: ENLC l s c u

If it continuously fails...

If the front panel display hangs on T:20, the VGMC is not getting an (ELAN) IP address. The reason for this may be:

  1. The loadware version is wrong (CF card)
  2. The card is not set to follower/BootP mode
  3. The MAC address is wrong in Element Manager

Manually update the card:

  1. Remove the VGMC, and remove the Compact Flash (CF) card on it. Using a CF to USB reader, mount the card on your PC.
  2. Locate the IPLxxxxx.sa loadware file in the root directory of the Signalling Server software CD, and copy it to the PC.
  3. Rename this file exec (no extension), and copy it to the CF, replacing the older version already there.
  4. Put the CF card back on the VGMC, and reseat the card. Wait for it to boot, and subsequently respond to PING.
  5. If it's a new VGMC, try Save and Transfer again - if it's a replacement, it should now automagically register.
    Use an IPLxxxxx.sa file matching the Signalling Server version, which is found in Element Manager on the home screen after expanding "Signalling Server". Or copy the exec from an already installed/working card. Signalling Server Version
IPL40055.sa IPL45025.sa IPL45088.sa IPL55012.sa  ◄ Download, rename to "exec", and copy to CF.

Set as "follower":

  1. Connect a TTY to the "Maint" port: 9600/8n1. The default password is: admin1/0000
  2. Enter the command clearLeader. This makes the card a "follower", invoking BootP mode.
  3. Reset the card using the front panel reset button. After a booting, the card should respond to a ping.
  4. If you are unsure about the cards MAC address, watch carefully for it during the boot sequence.
  5. The itgCardShow command displays information about a Voice Gateway Media Card.

Reset the CLI username and password:

  1. Connect a TTY to the "Maint" port: 9600/8n1.
  2. Reset the card using the front panel reset button, and watch the TTY output.
  3. Enter jkl when prompted to enter the BIOS, note: there's only a six second window!
  4. At the CLI prompt, enter the following command: shellPasswordNvramClear
  5. Type reboot at the prompt to reboot the card. The default password is: admin1/0000

Erase all settings in NVRAM:

  1. Connect a TTY to the "Maint" port: 9600/8n1.
  2. Reset the card using the front panel reset button, and watch the TTY output.
  3. Enter jkl when prompted to enter the BIOS, note: there's only a six second window!
  4. At the CLI prompt, enter the following command: nvramClear
  5. Type sysReboot at the prompt to reboot the card.

Force 10 Mbps, Full duplex:

Sometimes auto-negotiate will not work, you will see the TLAN link light dropping, PING has only intermittent success. 

IPL> tLanSpeedSet 10100         set speed to auto-negotiate ("10"= set 10 Mbps)
value = 40 = 0x28 = '('             
IPL> tLanDuplexSet 0            enable Full-duplex mode ("1"= half-duplex mode)
value = 1 = 0x1
IPL> itgCardShow

TLAN (ixpMac0) stat: 10 Mbps, Full duplex  (No Carrier)      ◄ Full duplex set

Now, force the associated ERS TLAN port to 10 Mbps, and full-duplex.
