Notes

Note 1 - Unity systems shipped with OE version 4.1.0.8940590 (Factory-only version) come with this note: Due to an issue found in Unity OE (Operating Environment) 4.1.0.8940590 (currently loaded on this Unity system) we recommend upgrading to the latest Unity OE version upon install of your new system.

 

Note 2 - Unity XT (x80/F models) was released in the same day as Unity OE 5.0.0.0.5.116. Unity OE 5.0 and later releases are compatible with the existing Unity models x00/F and x50/F, as well as the new x80/F models (Unity XT). Note however, that the new x80/F models require a minimum of Unity OE 5.0.

 

Note 3 - There is a requirement to disable TLS 1.0/1.1 and enable TLS 1.2 before performing an upgrade to Unity OE 5.5. See Dell Unity: Alert 14:b20080 TLSv1.0 and TLSv1.1 are not secure. It is recommended that you use TLSv1.2 and Dell Unity: How to Disable TLS 1.0 and 1.1 on Unity Array for details.
