Features
Here are the hardware features of the AT-FS900M Series Fast Ethernet
Switches.
Twisted-Pair
Ports
Here are the basic features of the 10/100 Mbps twisted-pair ports:
8, 16, or 24 ports per switch
10Base-TX and 100Base-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
RJ-45 connectors
SFP Slots All three switches support both 100Base-FX and 1000Base-SX/LX
transceivers. The switches support slots for SFPs as follows:
One SFP slot on the AT-FS909M and AT-FS917M switches
Two SFP slots on the AT-FS926M switch
Note
The AT-FS900M Series SFP slots are paired with twisted pair ports
on the switch to form combo ports. For more information, see
“Combo Ports” on page 22.
Note
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 ATI SFP modules
supported by the AT-FS900M Series switches.

LEDs The following lists the switch LEDs:
Power LED; refer to “POWER LED” on page 23.
Fault LED; refer to “FAULT LED” on page 24.
Speed and Duplex Mode LEDs; refer to “MODE LEDs” on page 24.
Speed/Duplex and Link/Activity LEDs for the twisted-pair ports;
refer to “Port LEDs” on page 25.
Link/Activity LEDs for the SFP slots; refer to “SFP Slot LEDs” on
page 26.
Installation
Options
The AT-FS900M Series switches can be installed in the following ways:
Rack mounted in a 19-inch equipment rack
Mounted on a desk or tabletop
If installing the switch in an equipment rack, rack mounting equipment
provided with the switch depends on the switch model as follows:
AT-FS909M and AT-FS917M: rack mounting equipment must be
purchased separately. The rack mounting kit model number is AT-
RKMT-J05.
AT-FS926M: rack mounting hardware is included in the shipping
package.
MAC Address
Table
Here are the basic features of the MAC address table:
Storage capacity up to 8KB MAC address entries
Automatic learning and aging

Management Software
The switches are shipped with the ATPro management software pre-
installed. The software provides a web-browser interface for in-band, over-
the-network management.
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.
