Industrial Link ISM-G844
Industrial 8-Port Managed Redundant Ring Gigabit Ethernet Switch
with 4* 10/100/1000TX + 4*Gigabit Combo SFP port
Overview
LinkPro ISM-G844 is a managed redundant ring Ethernet switch with 4x10/100/1000Base-T(X)
and 4xGigabit Combo ports. With completely support of Ethernet redundancy protocol,R-Ring
(recovery time < 20ms over 250 units of connection), and MSTP/RSTP/STP (IEEE 802.1s/w/D) can
protect your mission-critical and 4xGigabit Combo ports With completely support of Ethernet
redundancy protocol, and MSTP/RSTP/STP (IEEE 802.1s/w/D) can protect your mission-critical
applications from network interruptions or temporary malfunctions with its fast recovery technology.
ISM-G844 can be managed centralized and convenient by a powerful windows utility — Super View.
ISM-G844 supports new DDM (Digital Diagnostic Monitoring) function, which can monitor instantly the
status of electrical voltage, current and temperature. The redundant DC power inputs guarantee a non-stop operation.
The backup power input will take over immediately when the primary DC power input fails. ISM-G844 provides relay
outputs that can be set up to indicate events with urgency to notify or warn the technicians, so they can quickly respond to the
message in priority. Therefore, the switch is one of the most reliable choice for highly-managed and Fiber Ethernet application.
