Craft Console Cable

A Craft console cable connects a local Craft console to the Craft port on the front panel. The cable is

constructed as a straight-through connection between a standard, DB-9 male connector at the system end

and a DB-9 female connector at the computer terminal end. Table A-2 lists the pin assignments.

Ethernet Crossover Cable

An Ethernet crossover cable is a shielded cable that connects the Ethernet port on a PC to the Ethernet

management port on the front panel. Both ends of the cable are terminated in standard, RJ-45 eight-pin

modular plugs. Table A-3 lists the pin assignments.
