Backplane cable rerouting for Options 21Ð81 CE/PE and IPE backplanes

In a standard configuration, an IPE Module can be placed in any four adjoining peripheral slots on an Options 21Ð81 CE/PE or IPE shelf. This is possible when the slots are fully cabled to accommodate 24 tip and ring pairs per slot. However, older CE/PE or IPE shelves (NT8D37 AA or DC vintage) do not have fully cabled backplanes. In those cases, you must reroute backplane cables inside the CE/PE or IPE shelf before installing the IPE Module.

To determine whether you have a fully cabled CE/PE or IPE shelf, check the back of the CE/PE backplane (NT8D11) or the IPE backplane (NT8D37). If the backplane has eight cables connected on each side, your backplane is fully cabled therefore you can install the IPE Module without rerouting cables. If there are any shrouds on the backplane left unattached, follow the appropriate procedure in this section to modify the CE/PE or IPE shelf.

In the standard configuration of the NT8D11 CE/PE backplane and NT8D37 IPE backplane for a software release prior to Meridian 1 X11 Release 18, some slots on the backplane are fully cabled to accommodate 24 tip and ring pairs (three cable connectors). Most of the backplane slots, however, accommodate 16 pairs (two cable connectors). By adding and reconfiguring backplane cabling in the backplane slots, you can ensure that each backplane slot can accommodate 24 pairs. Once you have finished the rerouting process, the CE/PE or IPE cabinet can support the IPE Module.

CAUTION

Risk of system interruption

It is important to note that you should reroute only those cables connected to the segment of the backplane where the IPE Module is installed.

Backplane cables connect each connector port of an I/O panel with the appropriate slot on the backplane. For example, a backplane cable connects connector port A to a backplane slot. At the I/O panel, each backplane cable connects to a 50-pin connector. At the backplane end, each backplane cable
