Good news!!!!Today, in a call with Christian Dinarte, a Dell Network specialist from Brazil, we do  update Bios of Switch, and after this update we reinstalled ONIE and FTOS and switch appers to be live again!Thanks all for help!!
I have 2 S3048-ON in stack, and after 1 year without reboot, we turn off and turn on the switches, and one switch dont back more. On startup switch show errors and reboot again and again... I try to uninstall ONIE and install again, but I cant install because receive errors about cannot read /dev/i2c-2, unable to found serial number  and not found base mac address Ideas about this problem?   errors on boot:   Dell EMC Networking OS Release 9.14(2.4)NetBSD 7.1.2 (S3000) #0: Fri Nov 8 09:11:45 PST 2019NetBSD 7.1.2 (S3000) Notice: this software is protected by copyrightDetecting hardware...: EMC230x RPM based fan controller 0netbsd_bde_create() faileddone.WARNING: 5 errors while detecting hardware; check system log.ifconfig: exec_matches: Device not configuredroute: writing to routing socket: File exists     When I try to install FTOS (pendrive mounted): ONIE:/ # onie-nos-install /mnt/pendrive/FTOS-SG-9.14.1.10.bindiscover: installer mode detected.Stopping: discover... done.Error: Could not open file `/dev/i2c-2': No such deviceError: Could not open file `/dev/i2c-2': No such deviceNotice: Invalid TLV header found.
