This is the smallest, fully-managed Gigabit fiber switch for harsh environments, features 4 10/100/1000Mbps copper ports, 2 100/1000X SFP ports and redundant power system in an IP30 rugged but compact-sized case. The IGS-5225-4T2S can be installed in any difficult environment as it can operate stably under the temperature range from -40 to 75 degrees C. With such a slim enclosure, it does not need a big space to install. The switch features user-friendly yet advanced IPv6/IPv4 management interfaces, abundant L2/L4 switching functions and Layer 3 static routing capability. It allows either DIN-rail or wall mounting for efficient use of cabinet space. With 2 dual-speed SFP fiber slots, it can be flexibly applied to extend the connection distance.
