Product Model


The AST-IMC-M-4E2U2S-PSE is a 10/100M managed industrial PoE switch. It has 4*10/100 PoE
ports and 2*100/1000M TP/SFP combo ports, 1-4 ports support IEEE 802.3af/at PoE standard,
single port PoE power up to 30W, the maximum PoE output power is 120W. As a PoE
power supply device, it can automatically detect and recognize the power receiving equipment
that meets the standard and supply power through the network cable. It can supply power to POE
terminal equipment such as wireless AP, web camera, VoIP phone, industrial sensor through
network cable, and meet the network environment that needs high-density PoE power supply.
It is suitable for intelligent transportation, rail transit, electric power, mining, metallurgy and green
energy. Industrial scenes such as construction set up a cost-effective and stable communication



10/100Mbps access, Gigabit TP/SFP Combo Uplink

All series supports the combination of “10/100M Ethernet port + TP/SFP port ” , which enables users to
flexibly build networking to meet the needs of various scenarios.
Support non-blocking wire speed forwarding.

Support full duplex based on IEEE802.3x and half duplex based on Backpressure.

Smart PoE Function

4*10/100base-TX RJ45 ports support PoE power supply to meet the needs of POE in various industrial

Conforms to the IEEE 802.3af/at PoE power supply standard, automatically recognizes POE devices for
power supply, without damaging non-POE devices. The maximum POE output power of the entire device
reaches 120W, and the maximum POE output power of a single port is 30 W.

Support POE network management function, through the network management configuration, POE port
power allocation, priority setting, port power status view, time scheduling, etc.

Strong Business Processing Capability

Support IEEE 802.1Q VLAN, users can flexibly divide VLAN according to needs, and support QinQ configuration.

Support QoS, support port based, 802.1P based and DSCP based three priority modes and Equ, SP, WRR,
SP+WRR four queue scheduling algorithms.
ACL supports the filtering of data packets by configuring matching rules, processing operations and time
permissions, and provides a flexible access control strategy.
Support IGMP V1/V2 multicast protocol and support IGMP Snooping to meet the multi terminal HD video
surveillance and video conference access requirements.
Support STP/RSTP/MSTP production tree protocol, eliminates two layers of loops, and realizes link backup.
Support static convergence and dynamic convergence, effectively increases link bandwidth, achieves load
balancing, link backup, and improves link reliability.

Complete Safety Protection Mechanism

Support 802.1X authentication, provide authentication function for LAN computer, and control the
authorized status of controlled port according to the result of authentication.
Support port isolation , port mirroring.
Support port broadcast storm suppression.
Support port +MAC binding, IP+MAC+ port binding function.
