To install the NTMF94EA ELAN, TLAN, serial interface cable, complete the

steps in Procedure 18.

Procedure 18
Installing the NTMF94EA ELAN, TLAN, serial interface cable
1On Large Systems, connect the NTMF94EA ELAN, TLAN, and RS-232
Serial Maintenance I/O cable to the I/O panel connector for the left hand
card slot.
For Small Systems, connect the cable to the I/O connector in the cabinet
that corresponds to the IP Line card slot (see Figure 276 on page 859).
2Connect a shielded CAT5 Ethernet cable from the customer’s TLAN
Layer 2 or Layer 3 switch port to the RJ-45 port labeled “TLAN”.
3Connect a shielded CAT5 Ethernet cable from the customer’s ELAN
Layer 2 or Layer 3 switch port to the RJ-45 port labeled “ELAN”.
4Install the NTAG81CA serial cable into the faceplate Maintenance port.
This connection is used to configure the IP address for Leader 0. If
required, use the NTAG81BA maintenance extender cable.
Note: Alternatively, for a permanent connection to the maintenance port,
use the DB9 female connector on the NTMF94BA breakout cable to
connect a modem (using a null modem) or directly to a local TTY terminal.
WARNING
Plug all Voice Gateway Media Card ELAN network
interfaces belonging to the same node into the same
ELAN hub or Layer 2 switch port group.
WARNING
The serial maintenance ports presented at the faceplate
and at the backplane are identical. Do not connect a
terminal to both access points simultaneously. This
results in incorrect and unpredictable operation of the
Voice Gateway Media Card.
