Cisco 6509-E проблемы с БП

[megahertz0]

Добрый день! Есть шеститонник. В него вставлены два БП WS-CAC-4000W-US (US это тип вилки, мы просто заменили на грушу). Недавно вышел из строя первый БП. Выдернули, заменили. Все ок. Питание стало redundant. Через какое-то время заметил, что на втором БП нет никакой индикации. Проверили питание - все в порядке. Вытащили-вставили БП - видится. Но БП не стартует. Вот что пишет циска:

И самое главное, что лампочка fail на глючном БП не горит. Циска пишет, что power-supply 2 power-output-fail. Что это зничит? БП выдает неправильное паряжение на выходе? Я его, конечно, поменяю, но непоятно, чего он так внезапно умер? И самое галавное, что в лог ничего не высыпалось. Питание, к стати, нормальное, ИБП с двойниым преобразованием.
