When the IP trunk cards are installed, the red LED on the faceplate is

lit if: the card has rebooted; the card is active, butthere 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 (such

as 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. "F:10" temporarily appears on the display, which

indicates a Security Device test failure. Since IP Trunk 3.01 (and

later) does not use Security Devices, ignore this error.

Refer to "Media Card 32-port trunk card faceplate maintenance

display codes" (page 423) and "ITG-Pentium 24-port trunk card

faceplate maintenance display codes" (page 425) for a complete

listing of the codes.

Install NTCW84JA Large System I/O Panel 50-Pin ﬁlter adapter

For Large Systems, the standard ﬁltering is provided by the 50-Pin ﬁlter

adapters mounted in the I/O Panel on the back of the IPE shelf. The

ﬁlter adapter connects externally to the MDF cables and internally to the

NT8D81AA Backplane to I/O Panel ribbon cable assembly. Within the

adapter, all Tipand Ringpairs, including the TLAN subnet pairs, are ﬁltered.

For 100BaseT operation, the standard adapter must be replaced with the

NTCW84JA adapter which is identical to the existing adapter but has

unﬁltered TLAN Tip and Ring pairs.

For Cabinet systems, the standard I/O ﬁlter connector already supports

100BaseTX.

CAUTION

For Large Systems manufacturedduring 1998-1999and shipped

inNor th America, the IPE modules have the NT8D81BA Backplane

to I/O Panel ribbon cable assemblywith anon-removable Filter

Connector. The NT8D81BA is compatible with a 10BaseT TLAN

subnet, but if a 100BaseT TLAN subnet is required, order the

NT8D81AA Backplane to I/O Panel ribbon cable assemblyto

replace it. Do not try to install the NTCW84JA Filter Connector

onto the existing non-removableFilter Connector.

The NTCW84JA ﬁlter connector is required for separate subnets using

100BaseTX for the TLAN subnet connection.
