Re: Connectrix Brocade B Series Firmware (FOS) 5.1.0a?

If you go to the IBM support site and look for downloads for the IBM 2005-B32 (which is a Brocade 4100), it will let you leapfrog to the Brocade download site, and there are a heap of FOS's available for download.  Unfortunately, 5.1.0a isn't one of them, but there are others from the 5.1.x family, as well as 5.2.x, 5.3.x, and 6.x.

It might be worth a look to see if there is a combo that meets your needs?
