Transition Networks - Network Switches

Managed Hardened Switch, (8) 10/100/1000Base-T ports, (4) 100/1000Base-X SFP ports

P/N: SISGM1040-184D-LRT


(8) 10/100/1000Base-T + (4) 100/1000 SFP Ports
(Including DIN rail and wall mount brackets)


The SISGM1040-184D-LRT is a managed Gigabit switch suitable for connecting remote devices in hazardous environments. The (4) dual speed SFP ports provide the ultimate flexibility by allowing SFP fiber connections at 100Mb or Gigabit speeds at a variety of communication distances. The ports can also be used in a redundant ring for maximum network reliability. This switch has redundant input power connections and a fault alarm relay to ensure safe reliable operation in temperatures between -40°C and +75° C.
