CENTRAL PROCESSOR PACKAGE INSTALLATION

2.3CONNECTION OF THE CENTRAL PRO- CESSOR PACKAGE CABLES

When multiple CPP cabinets are reuired, the sys- tem layout will have been designed to minimize the cabling needed between cabinets. At minimum, it will be necessary to connect the ribon cables from the Inter-Cabinet Repeater (ICR) cards in the first cabinet, to the backplanes and power supplies in the expan- sion cabinets. Depending on the size of the CPP, the cables are marked with either RED DOTS or GREEN DOTS.

Connect the cables marked with a RED dot to the Line Terminator Board, which is also marked with a RED dot. Perform the same procedure if the cables are marked with GREEN dots (see Figure 2-2.

In some cases, it may be necessary to connect I/O ribbon cables or intercabinet mute wiring. Instruc- tions for these details are unique to each system and

will be found in a document titled "Installation Notes" at the front of the "Customer Data" Section in in Vol- ume 1 of the VR-CM50 Console Service Manual.

2.3.1 CABLE ROUTING

60" CPP cabinets are designed for cable feed from the bottom of the cabinet.

80" CPP cabinets are designed to accept cable feeds from either the top or the bottom of the cabinet. 88" CPP cabinets are shipped with the assumption that the cables will feed from the top or from beneath the floor. If cable access through the bottom rear cowl is desired, remove the black hole plugs from the cowl and exchange them with the cable bushings in the top vent panel.
