TransmitIP trunk card conﬁguration data from TM 3.1 to the IP trunk cards 263

Procedure 28

Installing a Backup Leader in IP Trunk3.01 (and later)

Step Action

1Ensure both IP trunk cards are running the same version of software.

The software version is displayed when logging into the IP trunk

cards. The software version can also be displayed by typing the

command swVersionShow at the ITG CLI interface.

2If the software versions are different, followthe upgrade erase

procedure. Download the software from www.nortel.com home page.

Follow the links to Customer Support and Software Distribution or

go to www.nortel.com/support. If problems are encountered, please

contact the support group or GNTS.

3Ensure the D-channel is conﬁgured to handle the extra B-channels

that are installed. ISLM = 382 max.

4Use NTMF94 cables for ITG-Pentium24-por t trunk cards with a

DCHIP card installed. Use NTCW84 cables for ITG-Pentium 24-port

trunk cards that do not have a DCHIP card installed.

Use an A0852632 L-adapter for Media Card 32-port trunk cards. If

the Media Card 32-port trunk card has a DCHIP card installed, use

the DCHIP cable assembly NTMF29BA along with the L-adapter.

5In TM 3.1, in the same Node as Leader 0, conﬁgure Leader 1.

Ensure the correct MAC address, ELAN network interface IP

address, and TLAN network interface IP address assigned forthe

Backup Leader (Leader 1) are used, and add them. The ELAN

network interface IP addresses must be on the same subnet for all

cards. Though on a different subnet than the ELAN network interface

IP addresses, TLAN network interface IP addresses must also be

on the same subnet. The MAC address used must always be for

the ELAN network interface. The MAC address for the Media Card

32-port trunk card is printed on the IP trunk card faceplate under the

ELAN network interface. The MAC address for the ITG-Pentium

trunk card is printed on the card faceplate under MOTHERBOARD.

6If the card (Leader1) has been conﬁgured previously,perform the

Clear Leader command at the ITG CLI interface. When this IP

trunk card is rebooted, it comes up as a Follower/BLDR card. All

conﬁguration data is cleared on the card. It is not necessary to use

the setLeader command.

7Disable Leader 0 and Leader 1 from the system interface. Disable

the IP trunk card at the system CLI to ensure it is disabled, even if

the LED on the IP trunk card is lit. For information on how to disable
