Chapter 7: Cabling XEM2 Line Card Ports
Cabling Twisted Pair Ports
178
Here are the guidelines to cabling twisted pair ports on the XEM2-8XSTm,
XEM2-12XT and XEM2-12XTm Line Cards:
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 or higher.
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.
