• For PLA v1 models (for example, PLA-400, PLA-401, PLA-470, PLA-491 and so
on) upgrade the firmware version from 1.4.5 to at least version 3.0.5. Refer to
the PLA-4XX series User’s Guide for instructions on how to do this.
• For PLA v2 models (for example, PLA400 v2, PLA402 v2, PLA401 v2, PLA470 v2
and so on) make sure the firmware version is at least version 3.0.5.
• For PLA v3 models (for example, PLA401 v3 and PLA402 v3) the factory default
firmware version is 3.3.4.
Note: You cannot downgrade the PLA-407’s firmware to a version earlier than 4.0.1.
8.3 Compatibility Diagrams
Use Configuration Utility version 3.3.4 to manage PLA v2 and PLA v1 models with
firmware versions 3.0.5.
This diagram below shows a Powerline network where two PLAs have an earlier
firmware (1.4.5) that cannot be managed by the 3.3.4 Configuration Utility. You
should upgrade the firmware of these PLAs.
