Migration and upgrade path from PMP 430 network to PMP 450
network
With System Release 12.2 a currently deployed PMP 430 sector can be migrated to a PMP 450 sector using
the interoperability feature. Operators can keep the currently deployed PMP 430 SMs in the network, deploy
more PMP 450 SMs in the same sector and/or replace the existing PMP 430 SMs with PMP 450 SMs.
Operators, who want to upgrade their sector, can follow these steps:
1. Upgrade the PMP 430 sector (AP and SMs) to Release 12.1 software load using the OFDM CNUT
package
CANOPY121BUILDOFFICIAL_OFDM_AES.pkg3
(CANOPY121BUILDOFFICIAL_OFDM_DES.pkg3 for DES systems)
, if Release 12.1 is not currently
used.
2. Upgrade the PMP 430 sector (AP and SMs) to Release 12.2 software load using the OFDM CNUT
package
CANOPY122BUILDOFFICIAL_OFDM_AES.pkg3
(CANOPY122BUILDOFFICIAL_OFDM_DES.pkg3 for DES systems).
The PMP 430 SMs automatically reboot after the upgrade and they start scanning in the last used
mode, which in this case is the PMP 430 mode. Since the PMP 430 AP has not been replaced by a
PMP 450 AP yet, all PMP 430 SMs will connect to the original PMP 430 AP.
3. Ensure channel bandwidth, color code, encryption, authentication and frequency list are correctly
configured on the new PMP 450 AP and PMP 430 SMs.
4. Uninstall the PMP 430 AP and install a PMP 450 AP.
The PMP 450 AP requires a different power supply (29V) than the PMP 430 AP. The power supply
needs to be replaced before installing the PMP 450 AP.
The PMP 430 SMs will go out of session and start scanning again. They will scan in PMP 430 mode
first, because that was the last used mode, and will not connect to the PMP 430 AP. After 10 minutes
the PMP 430 SMs start scanning in PMP 450 interoperability mode, connecting to the PMP 450 AP.
5. Deploy additional PMP 450 SMs alongside the existing PMP 430 SMs and/or upgrade existing PMP
430 SMs with PMP 450 SMs.
Once the PMP 430 AP is replaced with a PMP 450 AP, the MIMO CNUT package
CANOPY131_1BUILDOFFICIAL_MIMO_PMP450-_DESAES_S.pkg3
can be used to upgrade both the
PMP 430 SMs and the PMP 450 SMs connected to the PMP 450 AP.
When the PMP 450 AP and all the PMP 430 and PMP 450 SMs connected to it have been upgraded to
Release 12.2 it is not possible to downgrade the sector to a release prior to Release 12.2. The reason is that
Release 12.2 is the first that supports the interoperability feature, and with any prior release the PMP 430
SMs would no longer be able to connect to the PMP 450 AP.
If downgrading the PMP 430 SMs is necessary, the PMP 450 AP has to be replaced by a PMP 430 AP. In
this case, downgrading becomes possible and the sector is again a PMP 430 sector. If any PMP 450 SMs
were deployed in the sector, they will not be able to connect to a PMP 430 AP.
