Ko te nuinga o nga wa e whakamahia takirua ana nga kaiwhakawhiti whakawhiti muka i roto i nga punaha waea parahi-a-ira hei whakaroa i te tawhiti tuku. Heoi, i roto i taua kupenga o nga kaiwhakawhiti muka whatu e whakamahia takirua ana, mena ka rahua te muka whatu, te hononga taura parahi ranei i tetahi taha, karekau e tuku raraunga, ka mahi tonu te mahi a te whatu whatu ki tera taha, kaore e tuku raraunga ki te whatunga. I korero te kaiwhakahaere i te hapa. Na, me pehea te whakaoti rapanga penei? Ka taea e nga kaiwhakawhitiwhiti muka me nga mahi FEF me te LFP te whakaoti i tenei raru.

He aha te FEF i runga i te kaitahuri muka?

Ko te FEF e tu ana mo Far End Fault. He kawa e ū ana ki te paerewa IEEE 802.3u ka taea te kite i te he o te hononga mamao i te whatunga. Ma te whakawhiti i te muka whatu me te mahi FEF, ka taea e te kaiwhakahaere whatunga te kite i te he i runga i te hononga whakawhiti muka whatu. Ina kitea he hapa hononga muka, ka tukuna e te kaitahuri muka i tetahi taha he tohu hapa mamao na roto i te muka ki te whakamohio i te kaihuri muka i tera taha kua puta he korenga.Na, ko nga hononga parahi e rua e hono ana ki te hononga muka ka ka momotu aunoa. Ma te whakamahi i te kaitahuri muka me te FEF, ka kitea e koe te he i runga i te hono me te raru tonu. Ma te tapahi i te hononga hee me te whakahoki ano i te hapa mamao ki te kaitahuri muka, ka taea e koe te aukati i te tuku raraunga ki te hono he.

He pehea te mahi a te kaiwhakawhiti whatu me te mahi FEF?

1. Mena ka puta he rahunga i te mutunga o te whiwhinga (RX) o te hononga muka, ka kitea e te kaitahuri muka A me te mahi FEF te kore.

2. Ka tukuna e te Kaituku Ahu Ahu tetahi he mamao ki te Kaituku Ahurangi B ki te whakamohio i te mutunga o te korenga, na reira ka whakakorehia te mutunga tuku o te Kaituku Ake A mo te tuku raraunga.

3. Ka momotuhia e te kaikawe muka whatu A te taura parahi e hono ana ki tana whakawhiti Itarangi tata. I runga i tenei huringa, ka whakaatu te tohu LED kua momotu te hono.

4. I tera taha, ka momotuhia ano e te kaiwhakawhitiwhiti muka B te hononga parahi o tana whakawhiti tata, ka whakaatu hoki te tohu LED i runga i te whakawhiti e tika ana kua momotuhia tenei hononga.
