1-1 Overview
The Husky Series HME-421E/423E is a highly reliable and fault-tolerant Industrial 6-port Managed Ethernet
Switch with four 10/100Base-T(X) Ethernet ports and two multi-mode/single-mode ports. With the SC type
optic ports, HME-421E/423E transmits data at high speed for long distances up to 2km (multi-mode) or 30km
(single-mode). With its high performance, HME-421E/423E provides redundant self-recovery mechanism in
less than 10ms on full load which allows you to establish a redundant Ethernet network to build a backup ring
topology. With powerful network management functions, HME-421E/423E can be remotely configured by a
web browser, and managed by SNMP. Event notification can be defined via SNMP trap, Syslog, relay output
or E-mail. Security is enhanced with advanced features like Port base VLAN, Tagged VLAN and IP security.
Performance is optimized by Quality of Service and IGMP snooping/querying. The HME-421E/423E is
equipped with a terminal block to provide dual power inputs with reverse polarity protection. Its IP-30 housing
protection, wide operating temperature of -40 to 80℃ and DIN-Rail mounting is suitable for an industrial
environment.
