Cabling Twisted Pair Ports
Here are the guidelines to cabling the twisted pair ports:
 The cable specifications for the ports on the switch are given in
“Cable Requirements” on page 22.
 PoE is enabled by default on the ports on the AT-GS980M/52PS
switch.

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 1000Mbps.
 The ports support half- and full-duplex at 10Mbps or 100Mbps.
 The ports support only full-duplex at 1000Mbps.
 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.
