Publication 1756-UM051B-EN-P - November 2000

Installing the Ethernet Module 2-7

Attach either the AUI or RJ45 connector to the matching Ethernet port.

Applying Chassis Power

IMPORTANT

Connecting the module to the network via an

Ethernet switch instead of a hub reduces the number

of collisions and lost packets and increases the

bandwidth. See the Ethernet/IP Performance and

Application Guide, publication ENET-AP001A-EN-P,

for more information.
