INSTALLATION
Required Circuit Pack Positions
The required CP positions for Cabinet 1 are:
| | SLOT | CP | |
| | 1 | ZTN129 or ZTN130 (R3) | |
| | 2 | | |
I | I ZTN85 or ZTN131 (R3) | |
| | | | |
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.
