Chapter 6: Cabling the Networking Ports
Cabling Twisted Pair Ports
136
This section applies to the twisted pair ports on the following products:
XEM2-8XSTm Line Card
XEM2-12XT Line Card
XEM2-12XTm Line Card
Here are the cabling guidelines:
Minimum cable requirements are:
– 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.
The ports support full-duplex only.
Do not attach cables to ports of static or LACP port trunks until
after configuring the trunks on the switch. Otherwise, the ports will
form network loops that can adversely affect network performance.
