В этой ветке вы уже отвечали на похожую проблему: viewtopic.php?f=10&t=6896&p=32029&hilit=UBIFS#p32029
Наш ли это случай ?
Возможно ли восстановить свич или это гарантийный случай ?

Здравствуйте, после чего началась проблема?

[trepangus]

Добрый день,
после выключения и последующего включения он стал перезагружаться в цикле.

[trepangus]

Проблема была в плохом контакте для 48 вольтового источника питания. Не хватало длины контакта , видимо работал с дребезгом. Извлекли из стойки , переобжали концы. Сейчас все работает в номинальном режиме.

Отлично!
