Product Description

Speed
The 10/100Base-TX ports are capable of 10 megabits per second (Mbps)
or 100 Mbps speeds. The 10/100/1000Base-TX ports are capable of 10
Mbps, 100 Mbps, or 1000 Mbps speeds. You can set the port speed
manually or, since the ports are IEEE 802.3u Auto-Negotiation compliant,
you can allow the switch to set each port’s speed automatically. With
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 for the AT-8350 Switch.
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.
