Tlhaloso: Li-adapter tsa marang-rang tse tšehetsang mekhoa e tloaelehileng le e potlakileng Ethernet khetha lebelo leo li tsamaeang ho lona ka mokhoa o bitsoang autosensing . Autosensing ke karolo ea lintho tse bitsoang "10/100" Ethernet hubs , switches , le NICs . Ho ikoetlisa ho akarelletsa ho hlahloba bokhoni ba marang-rang ho sebelisa mekhoa e tlaase ea ho fana ka matsoho ho khetha Ethernet e potlakileng. Likoloi li ile tsa ntlafatsoa ho etsa hore ho falla ho tloha Ethernet ea setso ho ea ho lihlahisoa tsa Fast Ethernet habonolo.
Ha li kopane pele, lisebelisoa tsa 10/100 li fetola tlhahisoleseding e mong le e mong ho lumellana ka boemo bo tloaelehileng ba lebelo. Lisebelisoa tsena li tsamaea ka 100 Mbps haeba marang-rang a e tšehetsa, ho seng joalo ba theohela ho 10 Mbps ho netefatsa hore ke "karolo e tlaase ka ho fetisisa" ea tshebetso. Li-hubs tse ngata le li-switch li khona ho iketsetsa likoloi ho ea ka sekepe ho ea ka sekepe; tabeng ena, lik'homphieutha tse ling tsa marang-rang li ka 'na tsa buisana ka 10 Mbps le tse ling tse 100 Mbps. Lisebelisoa tsa 10/100 hangata li kenyelletsa li-LED tse peli tsa mebala e fapaneng ho bontša boemo ba lebelo boo hona joale bo sebetsang.
