Minimum cable requirements for the twisted pair ports are listed here:
10Mbps operations: Standard TIA/EIA 568-compliant Category 3,

100 ohm shielded or unshielded cabling, complying with IEEE
802.3i 10Base-T specifications.
100Mbps operations: Standard TIA/EIA 568-compliant Category 5,

100 ohm shielded or unshielded cabling, complying with IEEE
802.3u 100Base-TX specifications.
1Gbps operations: Standard TIA/EIA 568-compliant Category 5,

100 ohm, 4-pair shielded or unshielded cabling, complying with
IEEE 802.3ab 1000Base-T specifications. Category 5e is
recommended.
Note
Category 3 and 5 cables may be used for EN55024 immunity levels;
however, they are not recommended for IEC61000-6-2 and
EN50121-4 immunity levels.
Note
A Category 6 or 6a shielded or unshielded cable is required to meet
IEC61000-6-2 and EN50121-4 immunity levels.
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 23 on page 132 for the pinouts of the twisted-pair ports at
10 or 100 Mbps and to Table 24 on page 133 for the port pinouts at 1000
Mbps.
