Używam adaptera „XENPACK na SFP +” i „Bezpośrednio podłącz kabel SFP + do SFP +” - to komplikuje diagnozę.
Gdzie znaleźć przyczynę liczników wzrostu?

sprawdź siłę sygnału światłowodu, wyczyść zakończenia światłowodów (w tym na panelach krosowych), wymień układ optyczny.

Mike Pennington,
Używam kabla z bezpośrednim podłączeniem „SFP + do SFP +” z adapterem „XFP do SFP +”. Może coś z tej grupy wymaga wymiany.

Przepraszam, używam adaptera „XENPACK do SFP +” i „Bezpośredniego podłączenia kabla SFP + do SFP +”
