Features

This section describes the hardware features of the GS970M Series

Gigabit Ethernet Switches.

Twisted pair

ports

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

 GS970M/10, GS970M/18 or GS970M/28 switches: 8, 16 or 24

non-PoE ports per switch

 GS970M/10PS, GS970M/18PS, or GS970M/28PS switches: 8, 16

or 24 PoE ports per switch

 10BASE-T (IEEE 802.3i), 100BASE-TX (IEEE 802.3u) and

1000BASE-T (IEEE 802.3ab) compliant

 IEEE 802.3u Auto-Negotiation compliant

 Auto-MDI/MDIX

 PoE Plus

 Full wire-speed non-blocking

 IEEE 802.3x Flow Control in 10BASE-T/100BASE-TX full-duplex

operation

 IEEE 802.3x Back Pressure in 10BASE-T/100BASE-TX half-

duplex operation

 IEEE803.3z 1000BASE-T Flow Control

 Support for jumbo packets up to 10KB

 One RJ45 connector on front panel for RS232 console purposes.

SFP slots Here are the basic features of the SFP ports:

 GS970M/10, GS970M/10PS,GS970M/18 and

GS970M/18PS switches: 2 SFP ports per switch

 GS970M/28 and GS970M/28PS switches: 4 SFP ports per switch.

 Available for 100Mbps or 1000Mbps of fiber, and 1000Mbps of

copper

 Support 100BASE-FX and 1000BASE-SX/LX transceivers.

You need to 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 ATI SFP modules

supported by the GS970M Series switches.

LEDs Here is a brief description of the port LEDs:

 POWER and FAULT LEDs; refer to “POWER and FAULT LEDs”

on page 32.

 Link/Activity/Speed/PoE LEDs for the PoE twisted pair ports; see

“10/1000BASE-T/100BASE-TX Link/Activity/Speed LED and PoE

status LED” on page 34.

 Link/Activity/Speed/Duplex/Collision LEDs for the non-PoE twisted

pair ports; see “10/1000BASE-T/100BASE-TX Link/Activity/Speed

LED and Duplex/Collision LED” on page 36.

 Link/Activity LEDs for the SFP slots; see “SFP LEDs” on page 38.

 SD card LED: refer to “SD card LED” on page 39.

Note

The ecofriendly button turns off the LEDs (excluding the POWER

LED and SD card LED) to conserve electricity. See “ecofriendly

button” on page 41.

Installation

options

The switches can be installed in the following ways:

 Rack mounted in a 19-inch equipment rack

 Mounted on a desk or tabletop

 Wall mounted

Power

conservation

The switches implement Eco-Switch Green Power saving features and

use less power than the METI specification. The switches have the

following power conservation features:

 ecofriendly 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

1000Mbps (port power scaling not available at 10 or 100Mbps)

 Power shutdown on unused ports

MAC address

table

Here are the basic features of the MAC address table:

 Storage capacity up to 16K MAC address entries

 Automatic learning and aging
