Izixwayiso
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 yimishini ye-laser ingaba yingozi emehlweni abantu. Gwema ukuchayeka kweso emisebeni eqondile noma engaqondile.
Izithombe zemininingwane yomkhiqizo:
Umhlahlandlela Womkhiqizo Ohlobene:
Ukuze siqhubeke sithuthukisa indlela yokuphatha ngenxa yomthetho wakho wokuthi ngobuqotho, ukholo olukhulu kanye nekhwalithi ephezulu kuyisisekelo sokuthuthukiswa kwenkampani, sithatha kabanzi ingqikithi yokuthengiswa okufanayo emhlabeni jikelele, futhi siqhubeke sakha okuthengiswayo okusha ukuhlangabezana nezidingo zamakhasimende for Good. Ikhebula Lekhwalithi ye-Aoc/Dac - 25G SFP28 Intambo yokubona esebenzayo JHA-SFP28-25G-AOC – JHA , Umkhiqizo uzohlinzeka ku- kuwo wonke umhlaba, njengalokhu: iHonduras, iSacramento, iSerbia, Silwela ukwenza kahle, ukwenza ngcono okuqhubekayo kanye nokusha, sizibophezele ukusenza ukwethembeka kwamakhasimende kanye nokukhetha kokuqala kwabahlinzeki bemikhiqizo yemishini yezesekeli yemishini yobunjiniyela. Sikhethe, wabelane ngesimo sokuwina-win!
Ngu-Alexia wase-Belize - 2017.12.09 14:01 Lokhu abakhiqizi abagcinanga ngokuhlonipha ukukhetha kwethu kanye nezidingo zethu, kodwa futhi basinike iziphakamiso eziningi ezinhle, ekugcineni, saqeda ngempumelelo imisebenzi yokuthenga.
