CentreCOM® GS900M Copper Series

Layer 2 Gigabit Access Switches

Allied Telesis CentreCOM GS900M Series copper Gigabit
access switches are cost-effective and fully managed. GS900M
Series switches deliver flexible uplink connectivity with one small
form-factor pluggable (SFP) slot on the 8-port model and 2 or 4
unpopulated combo ports (10/100/1000T or 100FX/1000X) on the

16/24-port models.

Overview

CentreCOM GS900M Series switches
feature quiet operation with a compact,
fanless 8-port model and a variable
fan control feature on the 16/24-port
models. All models feature 0-50°C
extended temperature capability. In
addition, the CentreCOM GS900M
Series includes ECO LED, ECO Trigger,
and Power Saving Mode for energy
efficiency. CentreCOM GS900M Series
switches provide an intelligent, energy
efficient, and cost-effective solution for
the edge of the network.

Key Features

ۼ Web-based graphical user interface for

simplified administration

ۼ Supports up to 50°C extended

temperature

ۼ Eco-friendly

ۼ Flexible LAN authentication functions

ۼ Tri Authentication: Any one physical

port can support a combination of IEEE

802.1X, MAC, and Web Authentication.
Therefore, the user doesn’t have to set
each port configuration based on the
authentication method on the connected
device

ۼ Multiple Dynamic VLAN: The traffic from

a device is classified into a dynamic VLAN
after the connection is authenticated

ۼ IGMP v3 / MLD v2 Snooping: Limits the

flooding of multicast traffic by dynamically
configuring L2 interfaces so that
multicast traffic is forwarded to only those
interfaces associated with IP multicast
address
