CRITICAL INFORMATION: Do not install version 7.4 firmware on PFXi’s with a serial number lower than 107635.
The version 7.4 firmware update is only compatible with PFXi’s with serial number 107635 or higher, that are currently running firmware version 7.x (7.0, 7.1, 7.2 or 7.3). This is due to internal hardware changes from PFXi serial number 107635 onwards.
Version 7.4 is not compatible with any PFXi running firmware version 4.94 or any previous 4.xx, 3.xx, 2.xx or 1.xx firmware version.
