8. C300 Redundancy operation
8.2. Redundancy configuration restrictions
1.
Factory data, such as: Vendor ID, Product Type, and Product Code must be identical
to ensure same platform hardware.
2.
Firmware Type must be identical ensure same platform firmware. Synchronization
cannot be allowed across different personalities.
3.
The Build ID strings are compared to detect difference in firmware versions. Some
platforms that use physical memory transfer as part of their redundancy solution are
sensitive to a difference in firmware versions. This includes C300.
4.
The partner module must have a properly configured Device Index. If this module
has an odd Device Index N, the partner module has to have the even Device Index
N+1. Otherwise, if this module has an even Device Index M, the partner module has
to have the odd Device Index M-1.
