See 7. After the copy-to-mate operation, wait for both standby units to re-boot and verify that there are no
alarms.
Note
The standby unit may have a payload encryption failure alarm for up to about one minute after the
unit is up and running.
5 In a link with radio protection, remove the protection lockout, first on the remote and then on the local
unit. See Switchovers and Lockout
6 Verify that there are no alarms on the link.
You can set all master keys defined on the unit to zero value. To zeroize the master keys, enter the following
command in root view:
root> payload encryption key zeroize
Warning
Executing this command on a FIPS enabled unit formats the unit's disk, and renders the unit non-
operational. If it is necessary to use this command, contact Cambium Networks Technical Support
for instructions how to re-configure the unit.
This command has no effect on units that are not enabled for FIPS.
Note
Any time payload encryption fails, the Operational status of the link is Down until payload
encryption is successfully restored.
