Fast Recovery to a Redundant Ethernet Network
The GE-DSH-82 / GE-DSH-73 series features strong and rapid self-recovery capability
to prevent interruptions and outside intrusions. It incorporates advanced redundant
data Ring technology; Rapid Spanning Protocol (IEEE 802.1w RSTP) and a redundant
power supply system into customers' industrial automation network to enhance
system reliability and uptime in the harsh factory environments. It also protects
customer's industrial network connectivity with switching recovery capability that is
used for implementing fault tolerant ring and mesh network architectures. If the
Industrial network was interrupted accidentally, the fault recovery times could be less
than 20ms to quickly bring the network back to normal operation.
Tough, Environmentally Hardened Design
With IP-30 aluminum industrial case protection, the GE-DSH-82 / GE-DSH-73 series
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. The GE-DSH-82 / GE-DSH-73 series also provides a wide range of power
supply options suitable for multiple industries and for worldwide operation. The
feature of operating temperature range from -40 to 75 Degree C allows the Managed
Industrial Switch to be placed in almost any difficult environment.
Robust Layer 2 Features and Advanced Security
The GE-DSH-82 / GE-DSH-73 series supports robust advanced features including IEEE
802.1Q VLAN, GVRP, Port link aggregation, QoS, broadcast storm control, MAC
address filtering, IGMP snooping enhanced security and bandwidth utilization to fit a
variety of applications. Via aggregation of supporting port, the GE-DSH-82 / GE-DSH-
73 series allows the operation of high-speed trunk combining multiple ports.
Maximum up to 4 ports of the GE-DSH-82 / GE-DSH-73 series can be assigned for 4
trunk groups and support fail-over as well. Additionally, its standard-compliant
implementation ensures interoperability with equipments from other vendors.
