Note
Auto-Negotiation is activated as the default on all twisted pair ports
on the switch. To deactivate Auto-Negotiation and set the speeds
manually, refer to the AT-S39 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 Mbps operation,
Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded
twisted pair cabling is required.
Auto-MDI
The ports 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 crossover 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 twisted pair 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 switch ports can be
disabled so that you can set the duplex mode manually through the
switch’s management software.
