Ethernet switches remove the uncertainty from packet networks, preventing packet collision though network division and ensuring unimpeded message delivery. The ASF670 and 675 go further than that in delivering power over Ethernet (PoE) to four of the 28 ports available.
Four Gigabit Ethernet ports ensure speed is never a problem, and support for optical connections including SFP cages, ST, & SC, ensures that connections take full advantage of the available bandwidth.
The switch will take a low voltage, DC, supply from 9.6v upwards, but will happily run from high-voltage DC or AC as available. It also supports a redundant supply to ensure continued connectivity in the event of supply failure.
