Twisted Pair Ports

The AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS Layer 2

Gigabit Ethernet Switches feature 10, 16, and 48 twisted pair ports,

respectively. All ports are 10Base-T, 100Base-TX, and 1000Base-TX

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 63.

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.
