Chapter 5 Provisioning
Provisioning Root Server Recovery Mode
In Root Recovery mode, the root remains in server mode when it acquires TOD and
phase from its TOD source. When the root server is turned on after power failure or
after it has been serviced, it will automatically query time and phase from its TOD
source, and use this time and phase to steer the subtending servers time and
phase. Clients connected to the subtending server will also slew with the subtending
server. Figure 5-4 illustrates the root recovery process based on TOD source.
