Maintenance

When the IP trunk cards are installed, the red LED on the faceplate
is lit if: the card has rebooted; the card is active but there are no
trunks configured on it, or the card is active and has trunks, but the
trunks are disabled. If the LED does not follow the pattern described
(for example, remaining continuously flashing or weakly lit), replace
the card.

Observe the IP trunk card Faceplate Maintenance display to see
startup self-test results and status messages. A display of the type
"F:xx" indicates a failure. Some failures indicate that the card must
be replaced. Refer to

"Media Card 32-port trunk card faceplate

maintenance display codes" (page 421)

and

"ITG-Pentium 24-port

trunk card faceplate maintenance display codes" (page 423)

for a

complete listing of the codes.

Attach the TLAN Ethernet cable to the faceplate of the replacement
IP trunk card.

When connecting the IP trunk card to the TLAN subnet, the link
status LED on the IP trunk card faceplate associated with the voice
interface lights when the connection is made. The 100 Mbit/s link
status LED on the Ethernet Switch port also turns on when correctly
connected to the IP trunk card. This indicates that the corresponding
port is set to operate at 100 Mbit/s and that the link is good.

If the card being replaced is an ITG 8-port trunk card and the
replacement card is an ITG 8-port trunk card, the I/O cable must be
replaced. The following steps describe the I/O cable replacement
procedure:

a. Locate the NTCW84LA cable that was included in the ITG Trunk

1.0 to ITG Trunk 2.0 upgrade kit.

b. Remove the NTCW84MA cable from the I/O panel.

c. Disconnect the ELAN network interface CAT5 Ethernet cable

and label it as the ELAN subnet connection.

d. If connected, disconnect the DCH and maintenance cable from

the NTCW84MA.

e. Connect the new NTCW84LA cable to the I/O panel.

Connect the ELAN, TLAN, DCH and Maintenance cables (if
previously connected) to the I/O cable. If the card being replaced
is an ITG 8-port trunk card, connect the IP trunk card faceplate
to the TLAN subnet.

In the TM 3.1 IP Telephony Gateway - ISDN IP Trunk Main window,
select View > Refresh from the menu. Check that the replacement
IP trunk card status is showing "Unequipped".
