Installing a PIM cable
Install a PIM cable to provide the power connection to the BIP.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a PIM cable assembly identified by one of these PECs (labelled
at each end of the cable assembly near the connectors):
— NTHR54 for the cables to the PIMs in the lower shelf
— NTHR53 for the cables to the PIMs in the upper shelf
— NTHR55 for both upper and lower shelves
• The original PIM cable assemblies have been replaced by single cable
assemblies, and the amount of cable slack is less on the newer versions.
Although the PECs are similar, you may receive either version as a
replacement. Both versions perform the same. All versions have a
MATE-N-LOK II connector with Louvertec contacts at each end.
Procedure steps
1 At the PIM, press the connector in until both tabs click. The connector
mates only one way.
2 If the PIM cable is not already routed, route the cable up to the BIP
through the cable management brackets and up the BIP connector. The
cable path for each PIM is shown in the figure “Connection points of the
PIM cables” (page 488).
3 Plug the other end of the PIM cable into the BIP.
4 Dress the cable slack and fasten with tie-wraps. Cut off the tie-wrap tails.
