FYI on verion 4.1 of the great JCI software
MS-NAE55xx-0, MS-NAE45xx-0, and MSNIE55xx-0 Engines Do Not Support Release 4.1
Due to internal software changes related to the support of newer versions of Microsoft .NET connection software, the earlier versions of the NxE55xx-0 and NAE45xx-0 engines do not have sufficient compact flash memory to support Release 4.1, and these engines do not have sufficient processor power to restart in an acceptable amount of time. The engine models listed in Table 1 cannot be upgraded to Release 4.1:
Table 1: Engine Models*
* Includes model numbers with U, G, or E suffix
Existing projects with the affected engines that wish to upgrade to Release 4.1 have two options:
1. Upgrade any of the affected engine models with newer versions of similar engines. A special upgrade program is available to provide newer controllers at a significant cost savings. For upgrade program details please contact your Regional Products Sales Manager.
2. Upgrade the Site Director, servers, and any newer supported engines to Release 4.1, and leave the nonsupported engines at Release 4.0 or earlier. Metasys system software supports mixed software revisions on devices, with a few limitations.
