Ethernet Direct Pioneers in Offering HMG-448GE-CD Extended Temperature Full Gigabit Managed Switch with Special Approvals

Taipei, Taiwan - Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions, launches HMG-448GE-CD, an enhanced version of Industrial Managed Gigabit switch that comes with extended operating temperature of -40 to 80 deg C especially designed for mission critical applications like in military, power & utilities, mining and other areas with hazardous environments.

The Husky Series HMG-448GE-CD is an extremely powerful gigabit switch designed to be the best Industrial Extended Temperature 8-port Full Gigabit Managed Ethernet Switch supporting four 10/100/1000T Ethernet ports and four small form pluggable (SFP) ports that support dual mode (100/1000) and Digital Monitoring Interface (DMI). The DMI technology in SFP enhances the digital interface which allows real-time access to device operating parameters. SFP supporting DMI is capable of real time monitoring of RX received optical power, TX output power, Laser Bias current, temperature, supply voltage & wavelength. HMG-448GE-CD provides redundant self-recovery mechanism in less than 10ms on full load which allows you to establish a redundant Ethernet network to build a back-up ring topology. Dual Homing and Ring Coupling are supported to add reliability by allowing a device to be connected to be network by way of two independent connection points.

HMG-448GE-CD offers powerful network management functions including SNMP, SMTP, SNTP, Quality of Service, Class of Service, IGMP, Snooping, LACP, DHCP, VLAN, RMON, Port Trunk, Port Mirror, User Authentication and IP Security. The HMG-448GE-CD is equipped with a terminal block to provide dual power inputs (12~48VDC and 18~30 VAC) with reverse polarity protection, 4000 VDC EFT and 8000 VDC ESD protection. The HMG-448GE-CD is a plug-and-play solution for your Industrial Ethernet applications compliant to Class 1 Division 2 environments.
