Specifications

Table 12 lists the cabling specifications for the 10/100/1000Base-T twisted pair ports.

Table 12. Twisted Pair Cabling and Distances

		Maximum
Speed	Cable Type	Operating
		Distance
10 Mbps	Standard TIA/EIA 568-B-compliant	100 m (328 ft)
	Category 3 or better shielded or
	unshielded cabling with 100 ohm
	impedance and have a frequency
	range that extends to 16 MHz.
100 Mbps	Standard TIA/EIA 568-A-compliant	100 m (328 ft)
	Category 5 or TIA/EIA 568-B-
	compliant Enhanced Category 5 (Cat
	5e) shielded or unshielded cabling
	with 100 ohm impedance and have a
	frequency range that extends to 100
	MHz.
1000 Mbps	Standard TIA/EIA 568-A-compliant	100 m (328 ft)
	Category 5 or TIA/EIA 568-B-
	compliant Enhanced Category 5 (Cat
	5e) shielded or unshielded cabling
	with 100 ohm impedance and have a
	frequency range that extends to 100
	MHz.

Note

The auto-MDI/MDI-X feature on the 10/100/1000Base-T ports automatically configures the MDI/MDI-X setting when a link is established with an end node. Available when a port is at the default setting of Auto-Negotiation, this feature allows you to use a straight- through twisted pair cable when connecting any type of network device to a port.

Disabling Auto-Negotiation on a port and setting the speed and duplex mode manually also disables the auto-MDI/MDI-X feature. A port where Auto-Negotiation has been disabled defaults to MDI-X. Disabling Auto-Negotiation may require manually configuring a port’s MDI/MDI-X setting or using a crossover cable.
