Перезагружать первый коммутатор отдельно желания не возникло по нескольким причинам:
1. Возникшие ошибки не приведут ни к чему хорошему.
2. Коммутатор имеет наивысший приоритет и после перезагрузки он снова станет мастером, а текущий мастер (в данном случае это был бы второй коммутатор) уйдет в перезагрузку.

UPDATE:

Error 9, Failed to open the file %9

Ошибка возникает при подключенной консоли. Так же консоль может вызвать рост CPU на 10-20 процентов.
