Upgrading to a new software version
Perform this task to upgrade the units to a new version of PTP 800 operational software.
CMU software version must be the same at both ends of the link. Limited operation may
sometimes be possible with dissimilar software version, but such operation is not
supported by Cambium.
Upgrade the remote end of a link before upgrading the local end, and for a 1+1 Hot
Standby link upgrade the inactive units and force a protection switch to them before
upgrading the active units. This approach maximizes system availability.
To upgrade the software, proceed as follows:
1
Save the pre-upgrade system configuration as described in Saving the system
configuration on page 6-119.
2
Go to the support web page (see Contacting Cambium Networks on page 2) and
find Point-to-Point software updates. Download and save the required software
image (for example PTP 800-nn-mm.dld2 or PTP 800-nn-mm-FIPS.dld2).
3
Select menu option System, Software Upgrade. The Software Upgrade page
is displayed:
