Datasheet

Allied Telesis CentreCOM GS900M Series copper Gigabit
access switches are cost-effective and fully managed.
GS900M Series switches deliver exible 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 100/1000FX) on the 16/24-port models.
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
efciency. CentreCOM GS900M Series
switches provide an intelligent, energy
efcient, and cost-effective solution for
the edge of the network.
» Web-based graphical user interface for simplified
administration
» Supports up to 50°C extended temperature
» Eco-friendly
» Flexible LAN authentication functions
» 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.
Key Features
» Multiple Dynamic VLAN: The traffic from a
device is classified into a dynamic VLAN after the
connection is authenticated
» 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
