["The ALL-SGI8108v2 is an unmanaged 8-port Gigabit industrial switch with 2 Gigabit SFP ports. To ensure safe and reliable use even in industrial environments, the hardware is protected by a sturdy metal housing and can be used in a temperature range of -40 to +80 degrees. When it comes to mounting, the ALL-SGI8108v2 also offers several options for secure mounting with table, wall or top-hat rail mounting. The delivery does not include a power supply, please order this separately. The ALL-SGI8108v2 industrial Ethernet switch has excellent adaptability to industrial environments (including mechanical stability, climate adaptation, electromagnetic environment adaptation, etc.), protection rating up to IP40, support for double redundant power supply, low power consumption and fanless cooling technology, MTBF (average trouble-free operating time) of up to 35 years, plug and play, no configuration, easy operation. It is suitable for industrial scenes such as intelligent transportation, rail transportation, electric power, mining, metallurgy and green energy construction to form a cost-effective and stable communication network. 10/100/1000Base-T automatic detection, full / half duplex MDI/MDI-X adaptive Gigabit SFP fiber interface, default matching optical modules, need to buy separately, (optional order single mode / multi-mode, single fiber / double fiber optical module. 10BASE-T: Cat3,4,5 UTP(=100 meters) 10BASE-T: Cat5 UTP (extend PoE 250m DIP switch for activation) 100BASE-TX: Cat5 or later UTP(=100 meters) 1000BASE-T: Cat5e or later UTP(=100 meters) Power: Green Solid on- power work normal, off- power disconnected System: Green Blink-work normally, solid on- soft work abnormal, fast blink- soft upgrade 10/100/1000T RJ45 Interfaces (Port 1 to Port 8): 1000 LNK/ACT (Green), 10/100 LNK/ACT (yellow) Blink-port connected with data transmission; Solid on-port connected without data transmission 100/1000Mbps SFP Interfaces (Port 9 to Port 10): Green Blink- port connected with data transmission;", "8-Gigabit ports with 2SFP Gigabit", "Fanless metal housing with optimized heat dissipation", "Easy to use as a table device, wall mount or DIN rail", "Extended temperature range of -40° ~ +80°", "with dialing functions of VLAN, 250m, PD AI", "IP40"]
