Cabling Copper Ports

78
Here are the guidelines to cabling the copper ports:
 The cable specifications are in "10/100/1000Mbps Ethernet
Copper Ports" on page 22 and "1/2.5/5/10Gbps Ethernet Copper
Port" on page 24.
 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.
 Ports must be set to Auto-Negotiation, the default setting, to
operate at 1000Mbps and higher speeds.

The ports support full-duplex only at 1000Mbps and higher speeds.

Do not attach cables to ports of static or LACP port trunks until
after you configure the trunks on the switch. Otherwise, the ports
will form network loops that can adversely affect network
performance.
