Izinyathelo Zokuphatha:Le divayisi isengozini yokulimala ngenxa ye-electrostatic discharge (ESD).
Indawo ekhululekile enganyakazi inconywa kakhulu. Landela imihlahlandlela ngokwezinqubo ezifanele ze-ESD.
Ukuphepha kwe-Laser:Imisebe ekhishwa ngelaser ingaba yingozi emehlweni abantu. Gwema ukuchayeka kweso emisebeni eqondile noma engaqondile.
Izithombe zemininingwane yomkhiqizo:
Umhlahlandlela Womkhiqizo Ohlobene:
Sihlala sinamathela kumgomo othi Quality First, Prestige Supreme. Sizibophezele ngokugcwele ekuhlinzekeni amaklayenti ethu ngemikhiqizo enenani elincintisanayo, ukulethwa okusheshayo kanye nenkonzo yobungcweti Yekhebula Elisebenzayo Elisebenzayo - 100-4*25G Ikhebula elikhanyayo elisebenzayo (QSFP28-4*SFP28) JHA-QSFP28-4SFP28-100G-AOC - JHA , Umkhiqizo uzohlinzeka kuwo wonke umhlaba, njenge: Chile, Cyprus, E-Ecuador, Kungakhathaliseki ukuthi ukhetha umkhiqizo wamanje kukhathalogi yethu noma ufuna usizo lobunjiniyela lohlelo lwakho lokusebenza, ungakhuluma nesikhungo sethu samakhasimende mayelana nezidingo zakho zokuthola usizo. Singakunikeza ikhwalithi enhle ngentengo yokuncintisana ngawe mathupha.
Ngu-Cindy wase-Seattle - 2018.06.28 19:27 Njengenkampani yokuhweba yamazwe ngamazwe, sinabalingani abaningi, kodwa mayelana nenkampani yakho, ngifuna ukusho nje, umuhle ngempela, ububanzi obubanzi, izinga elihle, amanani anengqondo, isevisi efudumele necabangelayo, ubuchwepheshe obuthuthukisiwe kanye nemishini kanye nabasebenzi banokuqeqeshwa kochwepheshe. , impendulo kanye nokubuyekezwa komkhiqizo kufike ngesikhathi, ngamafuphi, lokhu ukubambisana okumnandi kakhulu, futhi sibheke phambili ukubambisana okulandelayo!
