User's Manual of IGS-20040MT
Environmentally Hardened Design
With IP30 aluminum industrial case protection, the IGS-20040MT provides a high level of immunity against electromagnetic
interference and heavy electrical surges which are usually found on plant floors or in curb side traffic control cabinets. It 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.
Digital Input and Digital Output for External Alarm
The IGS-20040MT supports Digital Input and Digital Output on its upper panel. The external alarm enables users to use Digital
Input to detect external device's status (such as door intrusion detector), and send event alarm to the administrators. The Digital
Output could be used to alarm the administrators if the IGS-20040MT port is link-down, link-up or power-dead.
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
8 ports for trunking and supports connection fail-over as well.
