An issue was uncovered with R21.1.0.1 and R22.0 where a 450b radio could get stuck in a rolling reboot. This can occur when older software (16.2.3.1 or earlier) is upgraded directly to one of these releases and is a regionalized PTP-capable variant (i.e. an FCC, ISED or EU sales model ending in “B0xxA”). If a radio enters this state, it is possible to recover using the recovery mode and downgrading the software.
Note: If you have upgraded any radios already and they don’t exhibit this issue, you may continue to operate using these releases.
We have pulled down these releases to avoid further issues, and plan to have a release issued in the next couple of days, posted to the website and available for upgrade within cnMaestro.
Sorry for any inconvenience this may cause.
