The EDS-G308 Series from Moxa features rugged unmanaged Gigabit Ethernet switches with up to 8 ports, ideal for industrial environments demanding high bandwidth and reliability. Models with up to 2 SFP fiber-optic ports are also available, providing extended distance and EMI immunity.

The switches support 9.6 KB jumbo frames, redundant 12/24/48 VDC power inputs, and a built-in relay output to notify of power failures or port disruptions. Four DIP switches allow easy activation of broadcast storm protection, energy saving (IEEE 802.3az), and port failure alarms.
