Auto Detection - HBM Genesis GEN5i User Manual

I2679-4.0 en
The option provides an extra 1 Gigabit optical Ethernet link for the fastest
possible communications. The use of fiber optic links in local area networks is
now common place due to the inherent advantages of using fiber. High data
rates can be maintained without electromagnetic or radio frequency
interference (EMI/RFI). Longer distances can be achieved over that of copper
wiring. For the industrial user, fiber offers high-voltage isolation, intrinsic safety
and elimination of ground loops in (geographically) large installations.
With the fiber optic Ethernet Option you have:
Speed: 1 Gbit per second
l
Versatility: Ability to select copper or fiber
l
Innovation: High speed, excellent reliability and latest technology
l

Auto detection

At the system start-up the option auto-detects which of the interfaces is used
i.e. copper or fiber. When both interfaces are connected the fiber optic
connection has priority and will be used.
The initial selected interface remains in control as long as the system is
powered. To switch to another interface you must power-down the system and
start-up again with the required interface connected.
