Cabling The 10Base-T (Rj-45) Module - 3Com CoreBuilder 2500 Getting Started Manual

Cabling the 10BASE-T (RJ-45) Module

The 10BASE-T (RJ-45) module contains eight
10BASE-T ports using RJ-45 connectors. The ports
are implemented as MDI-X (media dependent
interface crossover) connections, meaning that a
workstation can be directly connected to the port
with a straight-through cable.
To cable the 10BASE-T (RJ-45) module:
Plug the male RJ-45 connector on the 10BASE-T
1
cable into the selected port on the module until it
clicks into place.
Attach the other end of the 10BASE-T cable to an
2
MDI port on a workstation or on a
repeater/concentrator.
Repeat steps 1 and 2 for the remaining ports on the
3
module.
Figure 4-8 shows the cabling of the 10BASE-T
(RJ-45) module using 10BASE-T cabling.
