Planning the Installation
Table 3 contains the cabling specifications for the twisted pair ports.
Note
The twisted pair ports on the switch feature Auto-MDI when
operating at either 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. For example, a port operating at 10 or 100
Mbps uses two pairs of twisted pair wiring while a port operating at
1000 Mbps uses four pairs of twisted pair wiring.
