Ahojte, na sieti mam viac kusov MK750UP, ale na jednom site mam dost specificky problem. Povodne som mal konfiguraciu nasledovne:
port1 - konnekt
port2 - power up - rocket dish32
port3 - power up - wisp station r2
port4 - power up - wisp station r1
port5 - power up - rocket sector90
Zariadenie fungovalo bez problemov, ale stale sa mi odpajal rocket na porte5. Musel som stale dislable/enable porta, ono potom nabehlo. Nezdalo sa mi to, tak som vymenil kable cca 2m a prehodil som rocket do portu4, ale nepomohlo a problemy sa opakovali, az kym mi rocket neskapal uplne.
Super, myslel som si, ze problem bol v rockete, tak som ho vymenil za novy kus. Lenze po tyzdni sa to cele zacalo opakovat, novy rocket v porte 4 sa mi nadalej odpaja. Skusal som rozne verzie upgradu aj na MK aj na UBNT, no zatial stale neviem, kde je problem. Doma mam druhy MK750UP, ale nemyslim si, ze vymena zariadenia pomoze... |

| To mi pripada ako problem s napajanim. Cim napajas to RBcko? Tie male RBcka mali tusim problem s PoE pri vacsej zatazi. Ma to limit 500mA na port, takze ked to mas napajane z 12V zdroja, tak je to urcite nad limit pri zatazi. |

| Tieto MK nie su vhodne na napajanie Rocket M5 zariadeni a vseobecne M5 zariadeni. UBNT maju pomerne vysoky odber + ak to máš na 12V tak sa nečuduj. Tento board je stavany na napajanie mikrotik HW. |

- ako vravi thomas; ak nie je, treba tam mat novy poe firmware.
- dalsia vec je maximalny odber. pozor na to !!
- urcili si si poe priority portov? skus si dat najvyssiu na rocket ci bude vypadavat
- ako mas napajany ten RB, dufam, ze nie cez ten jeden POE port ale pekne cez jack - to by tiez mohol byt problem
- zdroj jesne ze minimalne ten pribaleny 24V, menej ani neuvazuj....
ak mozes sleduj si ake su odbery na zariadeniach a uvedom si ze cim dlhsie kable mas tym mas vacsie straty - ake kable pouzivas? dufam, ze nejake kvalitnejsie a typ drot.
my mame 750UP niekolko desiatok a aj ked bolo zopar problemochy zariadeni, teraz myslim vsetky bezia ok. |
