ulanishi
Xizmat ko`rsatish maqsadlarida ishlatiladigan – ROMMON rejimida
marshrutizator elektr energiyasi manbasidan o`chiriladi va qayta ishga tushiriladi
(3.3-rasm).
3.3-rasm. Cisco Packet tracer muhitida
Router qurilmasining elektr
ta’minotini o`chirib/yoqish tugmasi
Marshrutizatorni ROMMON rejimida qayta ishga tushurish uchun odatiy
boshlang`ich IOS ishga tushish jarayoni to`xtatiladi,
buni amalga oshirish
terminalga bog`liq. Masalan, hyperterminalda – “Ctrl-Break”, teratermda – “Alt-
B”, Cisco Packet Tracer emulyatorida – “Ctrl-Break” va h.k.
Qurilmaga ulanib, u qayta ishga tushiriladi va IOS ishga tushirilishida

Bu yerda
konfiguratsiya registri
confreg 0x2142
buyrug`i bilan o`zgartiriladi, natiyjada
marshrutizator Flash xotiraga yozilgan konfiguratsion
