* Please Note: After the official end of life date of v9.6 and v9.8 (31st December, 2020), we can no longer guarantee feature quality and quantity. Especially for all UTM features, significant functional losses are to be expected due to the deactivation of signature and pattern updates and the discontinuation of communication with external partners (e.g. cloud services).

Compatibility with the LANCOM Management Cloud

To ensure continued smooth operation with the LANCOM Management Cloud, LANCOM devices with an old firmware version must be updated to a newer version. The following firmware versions are the minimum requirement:

  • at least LCOS 10.12.0147 SU3
  • at least LCOS FX 10.4
  • at least LCOS LX 5.20 Rel
  • at least LCOS SX 3.30.0417 RU3

To use all the functions of the LANCOM Management Cloud, we recommend using the latest release version.
