I
t also
possesses an integrated power supply source with wide range of voltages (
12 to 48V DC
or
24V AC
) for worldwide high
availability applications requiring dual or backup power inputs. Being able to operate under the temperature range from
-40 to
75 degrees C
, the IGS-20040MT can be placed in almost any difficult environment.

Robust Layer2 Features
The IGS-20040MT can be programmed for advanced switch management function, such as dynamic port link aggregation,
Q-in-Q VLAN
,
Multiple Spanning Tree Protocol(MSTP)
, Layer 2/4 QoS, bandwidth control and
IGMP/MLD snooping
. The
IGS-20040MT allows the operation of a high-speed trunk combining multiple ports. It enables a maximum of up to 10 groups of
