Appendix C - Redundancy C-31
N:M Hub Modem Redundancy
Install the replacement unit in the desired rack location and make all connec-
tions. The unit should be powered on, but insure the switch port is powered off.
Restoring the acting primary unit spare configuration
Since the backup unit assumed the identity of the failed primary unit during
restoration, it will appear in the Subnet Manager as the original unit. Right-click
on the unit and open the Properties page. Go to the Configuration tab and select
the appropriate spare configuration imported in the preceding step. Be sure to
select the proper configuration to avoid IP address conflicts.
Select Restore to load the configuration.
Figure C-32
Restoring configuration
At this point, the network segment controlled by this primary unit will go down.
Power up the new primary unit using the drop down menu on the strip, or in the
sub-group. If the configuration is correct, the network segment will automati-
cally come back up after the unit reboots.
Cleaning up
Once the network has been restored, it will be necessary to create new configu-
ration backups from the drop-down menus and to reset the system roles. Insure
the status is OK. (It may be necessary to reset heartbeat flags)
