Cabling

Table 5 contains the cabling specifications for the twisted pair ports.

Note

The twisted pair ports on the switch feature auto-MDI when
operating at 10, 100 or 1000 Mbps. Each port is individually
configured as MDI or MDI-X when connected to an end node.
Consequently, you can use either a straight-through or crossover
twisted pair cable when connecting any network device to a twisted
pair port on the switch.
