Installing the Module
Module
10/100Base-T Module
RJ-45 ports wired
as MDI-X
Notes:
• The RJ-45 ports on the 10/100Base-T module are all wired as MDI-X ports. For connecting these to another switch
or hub, use a crossover cable; for connecting these to an end node, use a straight-through cable.
• Since the 10Base-T connections are through 10/100Base-T ports, if you ever want to upgrade the connections to
100Base-T operation, it would be best to cable the connections initially with category 5 cable.
