2==============================1) Conecte um cabo console ao
equipamento e abra um Emulador de Terminal (Hyperterminal, Tera
Terminal, ou qualquer outro) utilizando a seguinte configurao: Bits

Flow Control: Xon/Xoff 2) Tire o cabo de fora do switch. 3)
Aperte o boto mode (localizado na frente, do lado esquerdo do
equipamento) e ligue novamente. a) 2900XL, 3500XL e 3550: Solte o
boto mode quando o LED sobre a porta 1 apagar. b) 2940 e 2950:
Solte o boto mode quando o LED STAT apagar (aps soltar o boto mode,
o LED SYST piscar mbar). c) 2960 e 2970: Solte o boto mode quando o
LED SYST piscar mbar e voltar para verde (aps soltar o boto mode, o

LED SYST ficar verde (sem piscar). Aps soltar o boto mode o LED
SYST piscar verde. e) 2955: Nos switches 2955 no preciso apertar o
boto mode. Basta durante o boot enviar um break. Para isso devemos
