Chapter 1: Overview

IEEE 802.3u compliant, the port can set its speed and

duplex mode automatically with Auto-Negotiation, the

default setting. Auto-Negotiation can be disabled and the

speed and duplex mode set manually with the AT-S97

Management Software.

The wiring configuration of the port is set automatically with

auto-MDI/MDI-X to either MDI or MDI-X, depending on the

wiring configuration of the end node. This permits the use of

a straight-through twisted pair cable regardless of the wiring

configuration of the port on the network device.

The auto-MDI/MDI-X feature is only available when the port

is using Auto-Negotiation. If Auto-Negotiation is disabled

and the port’s speed and duplex mode are set manually,

this feature is disabled and the port defaults to the MDI-X

setting. Depending on the wiring configuration of port on the

remote device, you may need to manually configure the

MDI/MDI-X setting on the 10/100/1000Base-T Terminal port

or use a crossover cable.
