INSTALLATION

Make SIP Connection for CPU/Memory

In all cases, the CPU/Memory is connected to the SIP via an octopus cable. Since there are four ports on the CPU/Memory (port 1 for the SAT, port 2 for SMDR, port 3 for the DTU, and port 4 [reserved]), plugs 1 through 3 on the octopus cable are used to connect the peripheral equipment. (Plugs 7 and 8 connect to the ETU; plugs 4, 5, and 6 are not used.) Plugs 1, 2, 3, 7, and 8 plug into a designated adapter on the SIP.

1.Before installing the octopus cable for the CPU/Memory CP, label the 25-pair connector and flag-type tie wrap with a CAB 1 SLOT1 label from the cable label sheets (Figure 2-7).Position the label on the back of the hood of the 25-pair connector.

2.Label the octopus cable legs, close to the modular plugs, as follows:

3.Connect the cable to Cabinet 1, slot 1, and run the cable horizontally through the D-rings to the 50A Fanning Strip.

4.Mount the cable in the fanning strip (Figure 2-31).

5.Insert the octopus modular plugs into the Z210A2 Adapter jacks on the SIP per the Voice and Data Station Records Form (Figure 2-26).

6 . If an ETU is provided, connect modular plug 7 to SWITCH (cpu) jack on the ETU.

7.If a second ETU is provided, connect modular plug 8 to SWITCH (cpu) jack on second ETU.
