Cable Type
Standard TIA/EIA 568-B-
compliant Category 3 shielded
or unshielded cabling with 100
ohm impedance and a
frequency of 16 MHz.
Standard TIA/EIA 568-A-
compliant Category 5 or TIA/
EIA 568-B-compliant Enhanced
Category 5 (Cat 5e) shielded or
unshielded cabling with 100
ohm impedance and a
frequency of 100 MHz.
Standard TIA/EIA 568-B-
compliant Category 6 or 6a
shielded cabling.
The 10/100/1000 Mbps twisted-pair ports are IEEE 802.3ab compliant,
with automatic MDIX detection at 10 or 100 Mbps. (Automatic MDIX
detection does not apply to 1000 Mbps.) This feature automatically
configures the ports to MDI or MDI-X depending on the wiring
configurations of the end nodes.
Switch ports connected to network devices that do not support automatic
MDIX detection default to MDIX.
You may disable automatic MDIX detection on the individual ports and
configure the MDI/MDI-X settings manually.
Refer to Table 22 on page 123 for the pinouts of the twisted-pair ports at
10 or 100 Mbps and to Table 23 on page 123 for the port pinouts at 1000
Mbps.
