Reset the OUI
Introduction
System operators should run the updateOUI utility with the -r option to reset the
OUI of DHCTs in the database. The updateOUI utility, when used with the -r option,
changes the 00:02:DE identifier back to 00:01:A6 or 00:40:7B, whichever is
appropriate. System operators are required to run the updateOUI utility with the -r
option whenever they roll back from an upgrade to PowerTV OS 3.x.
