Приветствую уважаемые форумчане. Попал в руки коммутатор SNR S2960-24. При подключении через консоль отображает только статус загрузки и все. Команды вводить не дает. Подключаюсь фирменным проводом циско. Провод в порядке. Через него подключался к SNR-S2940-8G-v2 и все было нормально. Может 2960 в каком то режиме работает о котором я не знаю.

@lokos49rus, добрый день. Можете показать, пожалуйста, что видите в консоли?

Для SNR-S2960-24G должен подходить родной консольный кабель из комплекта черного цвета, с одной стороны DB9 - с другой RJ-45, либо стандартный Cisco-кабель также DB9 - RJ45.

Распиновка также стандартная для DB9:

DB9 (Female) - RJ45 (Male)
2-3
3-6
7-8
8-1
4-7
6-2
5-4

Настройки при подключении стандартные: 9600/8/N/1 без какого-либо Flow Control.

В консоли вывод следующий

Провод фирменный цисковский, с другим коммутатором SNR проблем не было.

[Evgeniy Rychkov]

Здравствуйте.

 

Согласно выводу консольное подключение вам показывает все этапы загрузки вплоть то просьбы ввести пароль, значит отображение верное.

На сколько я понял вы не можете далее ничего ввести. В этом случае смотрите настройки консольного подключения, в частности flow-control, либо попробуйте другой консольный кабель, т.к. я не встречал такого, чтобы вывод в консоли был, а ввести ничего нельзя было. То есть по факту кабель рабочий. Возможно, консольный разъем каким-то образом неисправен
