Amaswishi ochungechunge lwe-S5730-SI (i-S5730-SI ngamafuphi) amaswishi ajwayelekile esizukulwane esilandelayo se-gigabit Layer 3 Ethernet.Angasetshenziswa njengeswishi yokufinyelela noma yokuhlanganisa kunethiwekhi yekhampasi noma njengokushintsha kokufinyelela esikhungweni sedatha.
Ukushintshwa kochungechunge lwe-S5730-SI kunikeza ukufinyelela okuguquguqukayo okugcwele kwe-gigabit kanye namachweba angaguquki e-GE/10 GE uplink angabizi kakhulu.Ngaleso sikhathi, i-S5730-SI ingahlinzeka ngamachweba angu-4 x 40 GE uplink ngekhadi lesixhumi esibonakalayo.
