Ethernet Direct Pioneers In Offering Industrial Managed Switch with 4 10/100/1000 Plus 4 SFP Ports

Taipei, Taiwan, 6 December, 2007 - Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions, launches HMG-448G, an Industrial Managed Gigabit switch with 4-port 10/100/1000T & 4 SFP for Gigabit uplink. This switch is the first in the industrial market to provide total Gigabit flexibility.

Ethernet Direct offers a Mixed Media Full Gigabit switch that is truly open. The HMG-448G combines 4 Gigabit TX and 4 Gigabit SFPs into a cost effective unit. Using Small Form-Factor Pluggable (SFPs) you can select the Multi-Mode or Single-Mode interface that meets your requirements. HMG-448G delivers power, performance and reliability to increase the speed of the network and migration to Gigabit era a reality in Industrial applications.

The HMG-448G is Industrial Switch that is intended to be located on the plant floor to interconnect 8 Gigabit connections to provide true high speed communications. Developed to interconnect several Gigabit up-link ports of the distributed switches, the HMG-448 reduces wiring and allows for the required infrastructure for real-time applications

Industrial environments involve real time applications coupled with the increasing number of industrial devices now communicating over Ethernet and could cause an overload in your Industrial Ethernet traffic. The growth of Ethernet devices on the plant floor will mean greater amounts of communication consuming available bandwidth. Data from the plant floor will feed up to SCADA and Enterprise systems, while Application Servers will provide distributed information down to coordinate automation systems. Multicast messages and Peer-to-Peer synchronization will generate additional traffic as more real time applications are run over Ethernet.


o 4 10/100/1000T Gigabit Ethernet ports & 4 SFP ports

o Management by WEB, Telnet, Serial, Console, SNMP and Windows utility

o Redundancy via Gigabit X-ring, RSTP and STP

o Control using VLAN, GVRP, QoS, IGMP Snooping, LACP, Rate Limiting etc.

o Security via IP/MAC, Port binding, DHCP, IP access list, 802.1X, SNMPv3

o Diagnostics by port statistics, RMON Trap, E-mail alert, Syslog, Port Mirroring

o Power protection through wide range redundant power design, Power polarity reverse protection and Overload current protection

In order to provide an infrastructure that will handle this increasing traffic you need to consider using Gigabit connections at critical connections. Ethernet Direct offers rugged & reliable Gigabit Ethernet Switches that will provide years of reliable operation and able to handle your network loading in the future.
