Mulingo wachitetezo cha masinthidwe a mafakitale nthawi zambiri amatchedwa index ya IP chitetezo. IP imatanthawuza "chitetezo cha ingress, chitetezo chofikira", ndipo gawo lachitetezo limalembedwa ndi IEC (International Electrotechnical Association). Chifukwa chake, tikamagula masiwichi a mafakitale, ndi mlingo wotani wa IP wa ma switch a mafakitale?

Sankhani zida zamagetsi molingana ndi mawonekedwe ake osagwira fumbi komanso osalowa madzi. Mulingo wachitetezo cha IP nthawi zambiri umakhala ndi manambala awiri. Nambala yoyamba imayimira ndondomeko yowonongeka ya fumbi ndi zinthu zakunja (zida, manja, ndi zina zotero), mlingo wapamwamba kwambiri ndi 6; nambala yachiwiri imayimira ndondomeko yosindikizira yopanda madzi ya zipangizo zamagetsi, mlingo wapamwamba kwambiri Ndi 8. Chiwerengero chachikulu, ndipamwamba mlingo wa chitetezo.

Pogula ankusintha kwa mafakitale, ogwiritsa ntchito nthawi zambiri amasankha chosinthira chamakampani chokhala ndi mulingo woyenera wachitetezo malinga ndi malo omwe amawagwiritsa ntchito. Pakusintha kwa mafakitale, mulingo wa chitetezo cha IP ndi chilolezo cha fumbi ndi kukana kwa madzi, ndiye chimayambitsa kusiyana kwa index ndi chiyani? Izi makamaka zimagwirizana ndi mbiri ya chipolopolo cha switch. Zosintha zamafakitale zimaphatikizanso mbiri ya aluminiyamu aloyi ndi mbale zachitsulo. Mosiyana ndi izi, zotayira za aluminiyamu zimakhala ndi chitetezo chambiri.

Pazosintha zamafakitale, chitetezo chambiri chopitilira 30 chimatha kusinthira kumadera ovuta a mafakitale, ndikuwonetsetsa kulumikizana kotetezeka, kodalirika komanso kokhazikika pamasinthidwe amakampani.
