Стоявший в работе на удаленном объекте SG-17S неожиданно перестал отвечать на внешние запросы. Перезагрузка не помогла. Через некоторое время самопроизвольно отключились Ethernet интерфейсы мультиплексора.
По выезду на место были обнаружены ошибки при загрузке ОС, на всякий случай была произведена прошивка мультиплексора на актуальную версию внутреннего ПО, ошибок в процессе прошивки не было, однако сбои не ушли. При этом, сбои наблюдались в совершенно разных местах лога процесса загрузки. В основном выдавались сообщения "Bus error" и "Segmentation fault", в некоторых случаях наблюдался дамп стека и "Kernel Panic". Предполагаю сбои в работе ОЗУ мультиплексора. Прилагаю лог загрузки.
А теперь собственно, вопрос - есть ли у вас в Омске сервисный центр, занимающийся ремонтом оборудования?
