Here are the cabling guidelines:
Here are the minimum cable requirements:

– 100Mbps - Standard TIA/EIA 568-B-compliant
Category 3 unshielded cabling.
– 1/2.5/5Gbps - Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced
Category 5 (Cat 5e) unshielded cabling.
– 10Gbps -Standard TIA/EIA 568-C-compliant
Category 6a unshielded cabling.
The connectors on the cables should fit snugly into the ports, and

the tabs should lock the connectors into place.
The default speed setting for the ports is Auto-Negotiation. This

setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The ports must be set to Auto-Negotiation, the default setting, to

operate at 1Gbps or higher speeds.
The ports support full-duplex only.

Do not attach cables to ports of static or LACP port trunks until

after you have configured the ports on the switch. Otherwise, the
ports will form network loops that can adversely affect network
performance.
