2.5.2 Auto-sensing MDI/MDIX ports
Each 10Base-T/100Base-TX RJ-45 MDI/MDIX port allows you to connect to a computer or to a hub using
either a straight-through or a crossover Ethernet cable.
2.5.3 Front Panel Connections
You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports.
The following table describes the types of network cable used for the different connection speeds.
Make sure the cable length between connections does not exceed 100 meters
(328 feet).
