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 Tip and Ring pairs, 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 manufactured during 1998-1999 and shipped
in North America, the IPE modules have the NT8D81BA Backplane
to I/O Panel ribbon cable assembly with a non-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 assembly to
replace it. Do not try to install the NTCW84JA Filter Connector
onto the existing non-removable Filter Connector.
The NTCW84JA filter connector is required for separate subnets using
100BaseTX for the TLAN subnet connection.
Remove existing I/O panel filter adapter
The standard I/O filter adapter is shielded metal with a black plastic insert
connector. The NTCW84JA adapter uses yellow warning labels to indicate
EMC filtering modifications and which MDF connection points can support
100BaseT connection.
Follow the steps in Procedure 8 "Removing the existing I/O panel filter
adapter" (page 194) to remove the existing I/O panel filter adapter.
Procedure 8
Removing the existing I/O panel filter adapter
Step Action
1 Remove the ITG pack, or any other IPE pack, from the IPE shelf
card slot corresponding to the I/O Panel connector to be removed.
Make sure to use the I/O panel connector which corresponds to the
left slot number of the DCHIP card.
2 Remove the NT8D81AA Backplane to I/O Panel ribbon cable
assembly which is connected to the backplane side of the existing
