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.

Key highlights

• 19” managed switch

• Metal housing, ports on front or on rear (typical substation configuration)

• Up to 4 GbE ports (optical, electrical or combo ports)

• Up to 4 PoE ports (only with power supply type H/Z)

Hitachi Energy’s AFF670 and 675 provide 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.
