Спонтанная перезагрузка блока 3U

[AlexLir]

swd-r2410
Я ожидал, что блок не будет перезагружаться, сетевых штормов не было в это время и других предпосылок для перезагрузки не было.
Ничего не предвещало беды, Влад и я аутентифицировались в web интерфейсе блока и затем, внезапно, вопреки моим ожиданиям, произошла перезагрузка по watchdog.
