If rearrangement of circuit packs in the PBX is required to accommodate the system assembly, rearrange the packs as indicated on Worksheet
There is a maximum of one system assembly per Single Carrier Cabinet (SCC) or MultiCarrier Cabinet (MCC). This assembly occupies five slots and should be placed to the far right in the carrier. For thermal reasons, the system assembly should not be placed in MultiCarrier Cabinet C carrier position (top carrier position).
See Appendix A, ‘‘PBX Carrier Configuration Worksheets,’’ for detailed information on the rearrangement of circuit packs and slot restrictions.
DEFINITY LAN Gateway System Slots
The system assembly requires five contiguous port slots in the switch carrier. In this description, the five slots are referred to as the first through the fifth slot, with the understanding that they can be any five contiguous port slots. It is recommended that it be installed as far to the right as possible.
The slots are numbered from left to right on the front panel of the switch cabinet, and from right to left on the rear panel as shown in Figure
The first and second slots are covered by the DEFINITY LAN Gateway disk and removable media and are not connected to the switch backplane or amphenol connectors.
The third slot is connected to the Alarm Board (ALB).
The fourth slot is connected to the
