How to reset "Physical Scrty" on S2600GZ ?

Hello Everybody,

I have several servers on platform R2224GZ4GCSAS.

After power on the BMC sensor value "Physical Scrty" is 0x0000 and it's Ok. But after 30-60 minutes it switches to 0x0010. It cause warning in ESXi "System unplugged". Does anybody know how to reset this value to 0x0000 and why it switches to 0x0010 ?

NOTE: if I unplug all LAN cables it resets to 0x0000. It's funny but I can't use server without LAN connection. :-)

Thanks,

Sergey
