systems, Cisco UCS Manager 4.0(1n) or later.
The Version 03 SIOC is supported only with S3260 M5 or later server nodes.
Note
Do not mix different versions of SIOCs in the same system.
Note
If your system has two Version 03 SIOCs, they must have identical adapter cards. Do not mix adapter
Note
cards between Version 03 SIOCs in a system.
A Version 01 SIOC from a Cisco C3160 system cannot be installed in a Cisco S3260 system.
Note
If you move a SIOC from one chassis to another, the SIOC's CMC configuration is treated as
Note
incompatible and is automatically deleted. The CMC will sync with the active CMC configuration.
