Cabling

Table 7 contains the cabling specifications for the twisted pair ports.

Table 7. Twisted Pair Cabling and Distances

		Maximum
Speed	Type of Cable	Operating
		Distance


10 Mbps	Category 3 or better 100-ohm shielded or	100 m (328 ft)
	unshielded twisted pair cable

100 Mbps	Category 5 or Category 5E (Enhanced) 100-	100 m (328 ft)
	ohm shielded or unshielded twisted pair cable

1000 Mbps	Category 5 and Category 5E (Enhanced) 100-	100 m (328 ft)
	ohm shielded or unshielded twisted pair cable

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.
