Chapter 1: Overview

Twisted Pair Ports

The AT-x210-9GT, AT-x210-16GT, and AT-x210-24GT Layer 2 Gigabit

Ethernet Switches feature 9, 16, and 24 twisted pair ports, respectively. All

ports are 10Base-T, 100Base-TX, and 1000Base-T compliant. You can

set the port speeds and duplex modes either automatically with IEEE

802.3u Auto-Negotiation or manually with the management software.

The twisted pair ports feature 8-pin RJ-45 connectors. For the port

pinouts, see “Connectors and Port Pinouts” on page 54.

The ports have a maximum operating distance of 100 m (328 feet). For 10

Mbps operation, the ports require Category 3 or better 100 ohm shielded

or unshielded twisted pair cabling. For 100 or 1000 Mbps operation, the

ports require Category 5 or Enhanced Category 5 (5E) 100 ohm shielded

or unshielded twisted pair cabling.

The ports feature auto-MDI, which automatically configures the ports as

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

cables regardless of the wiring configurations of the ports on the end

nodes.

Note

A switch port connected to an end node that is not using Auto-

Negotiation should not use Auto-Negotiation to set the speed and

duplex mode, because a duplex mode mismatch may occur. In this

case, disable Auto-Negotiation and set the port’s speed and duplex

mode manually.
