cable system
A.1 10/100Mbps, 10/100Base-TX
When connecting your 10/100Mbps Ethernet Switch to another
switch, a bridge or a hub, a straight or crossover cable is
necessary. Each port of the Switch supports auto-MDI/MDI-X
detection. That means you can directly connect the Switch to any
Ethernet devices without making a crossover cable. The following
table and diagram show the standard RJ-45 receptacle/ connector
and their pin assignments:
