Planet FT-801 Инструкция по эксплуатации онлайн [9/18] 65672

If one of the optical conductors is bad (as shown in the diagram

box below), the converter with LLR function will return a no-link

condition to its link partner. With LLCF function also enabled, the

no-link condition is carried forward to the switch/hub where a trap

is generated to the management station, and the administrator

can then determine the source of the loss.

 NOTE:

LFP function is turn-on in default. This feature

can also be turned off via the side DIP-switch.

If you are familiar with the network installation

and for diagnostic purpose (i.e. check which

end is broken), you can turn it off and reset

the converter to make it take effect. Otherwise,

please remains it in the default position.
