5. Locate a convenient area to place the cable assembly unit close to the host processor so that

the ports are easily accessible for connecting devices. The cabinet must be located within
about seven cable feet, the length of the fanout module cable assembly, of the host
computer. The cabinet can be installed on the floor or table, or wall mounted.

6. Route the ribbon cables behind the wire-frame assembly of the cabinet with the “lead 1”

identifiers to the left as shown in Figure 2-13. The connectors on the fanout module and the
ribbon cables are keyed for proper alignment. Be sure the retaining clips are properly
secured when connecting the ribbon cables to the fanout module.

7. Connect the ribbon cable nearest the front of the wire-frame assembly to the fanout module

connector for Ports 9 through 16. Next, connect the other ribbon cable for Ports 1 through
8.

8. The fanfold module snaps into the wire-frame assembly from the front of the assembly (see

Figure 2-13). Put the slot on the left side of the fanout module over the wire tab on the left
side of the wire-frame assembly. Next, slide the right side of the fanfold module into the
wire-frame assembly until the two slots on the right of the module engage with the wire
tabs.
