372 Appendix B Interoperability in a mixed stack configuration
208700-C
Before you attempt to download new software (or upgrade software) to a Hybrid
(mixed) stack, you
must ensure that the Interoperability Software Version
Numbers (ISVN) are identical. That is, the ISVN number for the BayStack 450
switch and BayStack 410 switch must have the same ISVN as the BPS 2000. If the
ISVNs are not the same, the stack does not operate. The ISVNs and the
accompanying software release are:
• ISVN 1
— BayStack 410 or Bay Stack 450—version 3.1
— BPS 2000—versions 1.0 and 1.0.1
• ISVN 2
— BayStack 410 or BayStack 450—versions 4.0 and 4.1
— BPS 2000—versions 1.1, 1.1.1, 1.2, and 2.0
