Also, all DID Trunk circuit packs should be installed in Cabinet 1.
There are no other restrictions on CP position in a single-cabinet or
multicabinet system; however, you should refer to the power supply unit load
requirements for the maximum unit loads for each CP type within a single
cabinet.
Caution:
Be careful not to exceed unit load restrictions on each
cabinet.
Label Connectors on Back Cover
Each cabinet has twelve 25-pair receptacles across the bottom of the rear
panel.
These connectors link the CPs inside the cabinet to the Station
Interconnect Panel (SIP) and Trunk Access Equipment (TAE). The connectors
are numbered from 1 to 12 and correspond to the CP slots.
Using a felt-tipped pen, write the CP code for each slot in the box above the
connector number on the lower rear cover.
