Power Failure Recovery Procedure
 To recover after a power failure:
When AC power returns after a power failure, the system self–assigns a link–local address to the Deskset beginning with
number 169.254.
 If the Deskset is set for automatic IP address configuration, it searches for the DHCP server. If the DHCP server is found,
it assigns an IP address.
 If the Deskset is set with static IP addresses, the address does not change.
Once power has resumed after a power failure, we recommend that you check each Deskset, Gateway and ATA to confirm
that it has started up properly. If any of the system devices’ screens report Sync Failed or Synchronizing... for more than
10 minutes, refer to “Reintroducing a Deskset Into the System” on page 244 and “Reintroducing a Gateway or ATA Into the
System” on page 246 for recovery methods from these states. Log in as administrator using the IP address of a synchronized
device. Click System Settings/System Information and click Detailed Site Information to check system status. The table
will show you which devices are currently connected to the system.
