AT-8326GB Installation Guide

Auto-Negotiation, the switch automatically matches the highest

possible common speed between each switch port and each end node.

For example, if an end node is capable of only 10 Mbps, the switch sets

the port connected to the end node to 10 Mbps.

Note

Auto-Negotiation is activated as the default on all of the ports on

the switch. To deactivate Auto-Negotiation and set the speeds

manually, refer to the AT-S41 Management Software User’s

Guide.

Maximum Distance

Each twisted pair port has a maximum operating distance of 100 m (328

ft).

Type of Cabling

For 10 Mbps operation, Category 3 or better 100 ohm shielded or

unshielded twisted pair cabling is required. For 100 or 1000 Mbps

operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded

or unshielded twisted pair cabling is required.

Auto-MDI

All of the twisted pair ports on the switch are auto-MDI and IEEE

802.3ab-compatible. They automatically configure themselves as either

MDI or MDI-X. This feature allows you to use either straight-through or

cross-over twisted pair cables to connect devices to the ports.

Duplex Mode

Each twisted pair port on the switch can operate in either half- or full-

duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will

Auto-Negotiate the duplex mode setting. If the end node connected to a

twisted pair port on the switch is capable of full-duplex operation, the

switch sets the port to full-duplex. If the end node is capable of only half-

duplex, the port is set to half-duplex.

If desired, Auto-Negotiation on one or all of the twisted pair ports can be

disabled so that you can set the duplex mode manually through the

switch’s management software.
