This chapter provides descriptions of the AT-GS950/10PS, AT-GS950/ 16PS, AT-GS950/28PS, and AT-GS950/48PS Layer 2 Gigabit Ethernet PoE+ Switches and contains the following sections:

 “Features” on page 16  “Front and Back Panels” on page 18  “Management Software” on page 21  “Twisted Pair Ports” on page 22  “Power over Ethernet (PoE)” on page 23  “Combo Ports” on page 24  “LEDs” on page 26  “eco-Friendly Button” on page 36  “Power Supply” on page 38  “Fans” on page 39

Chapter 1: Overview

Note

Features

Here are the hardware features of the GS950/PS Series switches.

Twisted Pair

Ports

Here are the basic features of the 10/100/1000 Mbps twisted-pair ports:

 10, 16, 24, or 48 ports per switch  8, 16, or 24 Power over Ethernet (PoE) ports per switch  10Base-TX, 100Base-T and 1000Base-T compliant  IEEE 802.3u Auto-Negotiation compliant  Auto-MDI/MDIX  100 meters (328 feet) maximum operating distance  IEEE 802.3x Flow Control in 10/100Base-TX full-duplex operation  IEEE 802.3x Back Pressure in 10/100Base-TX half-duplex

operation

 IEEE803.3z 1000Base-T Flow Control  Support for Jumbo frames up to 10KB  RJ-45 connectors

SFP Slots The AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches

support both 100Base-FX and 1000Base-SX/LX transceivers. The AT-GS950/28PS switch supports 1000Base-SX/LX transceivers. The switches support either two or four slots for SFPs:

 Two SFP slots on the AT-GS950/10PS and AT-GS950/16PS

switches

 Four SFP slots on the AT-GS950/28PS and AT-GS950/48PS

switches

On the AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches, the SFP slots are paired with twisted pair ports on the switch to form combo ports. For more information, see “Combo Ports” on page 24.

You must purchase SFP transceivers separately. For a list of supported transceivers, contact your Allied Telesis distributor or reseller.

Note

See the product data sheets for the specific Allied Telesis SFP modules supported by the GS950/PS Series switches.

LEDs Here is a brief description of the port LEDs:

 Power LED/SYS; refer to “PWR/SYS LEDs” on page 26.  Speed and link/activity LEDs for the twisted pair ports; refer to “10/

100/1000 BaseT Link Activity LEDs” on page 28.

 Link/activity LEDs for the SFP slots; refer to “SFP LEDs” on

page 31.

 eco-Friendly button turns off the LEDs to conserve electricity; refer

to “PoE LEDs” on page 33.

Table

The GS950/PS Series switches can be installed in the following ways:

 Rack mounted in a 19-inch equipment rack  Mounted on a desk or tabletop  Wall mounted for the AT-GS950/10PS, AT-GS950/16PS, and

AT-GS950/28PS only

The GS950/PS Series switches have the following power conservation features:

 eco-Friendly button to turn off the port LEDs when the system is

not being monitored

 High-efficiency power supply  Power scaling based on traffic loads on ports operating at 1000

Mbps (port power scaling not available at 10 or 100 Mbps)

 Power shutdown on unused ports

Here are the basic features of the MAC address table:

 Storage capacity up to 16KB MAC address entries  Automatic learning and aging

Management Software

The switches are shipped with the management software pre-installed. The software provides a web-browser interface for in-band, over-thenetwork management. Although the three models have the same features, each has a different management software program. The programs are:

 AT-S110: refer to the Web Interface User’s Guide for the

 AT-S111: refer to the Web Interface User’s Guide for the

 AT-S112: refer to the Web Interface User’s Guide for the

 AT-S126: refer to the Web Interface User’s Guide for the

In the unlikely event that the management software becomes corrupted or damaged on the switch, you can download the software from the Allied Telesis corporate web site and reinstall it on the switch. For instructions on how to install new management software, see the product documentation listed above.

Twisted Pair Ports

The AT-GS950/10PS, AT-GS950/16PS, AT-GS950/28PS, and AT-GS950/48PS Layer 2 Gigabit Ethernet Switches feature 10, 16, 24, and 48 twisted pair ports, respectively. All ports are 10Base-T, 100BaseTX, 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 71.

The ports have a maximum operating distance of 100 meters (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.

A switch port connected to an end node that is not using AutoNegotiation 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.
