Chapter 1: Overview

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 might occur. You

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

mode manually.

Combo Ports

The AT-GS950/8 and AT-GS950/16 Switches have two combo ports and

the AT-GS950/24 and AT-GS950/48 Switches has four combo ports. Each

combo port consists of one 10/100/1000Base-T twisted pair port and one

slot for an optional

100Base-FX or 1000Base-SX/LX SFP transceiver. The

twisted pair ports are identified with the letter “R” for “Redundant” on the

front faceplates of the units. The ports and slots are listed in Table 1.
