Virtual connect question

[kashiffaraz85]

There were TWO versions of the 4Gb VC-FC module produced. The first was part #409513-B21 and the second module, which has a more robust chipset, part #409513-B22. Support for the –B21 version of the 20 port 4Gb VC-FC module was dropped from the code base in VC Firmware version 4.10. Therefore, as described in the Virtual Connect release notes since release 4.10, the 20 Port 4Gb VC-FC modules (part #409513-B21) is no longer supported and cannot be upgraded past VC 4.01 (FC firmware version 1.44). If the domain contains these modules, you will not be able to upgrade the domain beyond VC firmware version 4.01. If you still have 4Gb VC-FC modules in your enclosure, you can verify whether they are the B21 or B22 version, by logging in to the OA and navigating to the Interconnect Bay as shown below.
