CAB 8n Hardware Manual

Crossover cables
Normal network cables are designed to connect the CAB to a network switch only. You cannot
use this type of cable to connect a CAB directly to a NION CM-1 card. For that you need a
crossover cable.
A crossover cable is terminated the same way as a normal cable, except that the TX and RX
pins are swapped at one end to allow the transmit pair of one device to connect to the receive
pair of the other.
Operating modes and redundancy
The CAB 8n supports a number of different operating modes, which are selected using the
CAB 8n device in NWare. This section shows the physical connections that are required in
each case.
Normal operating mode
In this mode, the CAB 8n communicates with the NION on the CobraNet network and a
connection to the NION is required for the CAB to continue to operate.
