VNX 1 OE for Block Download

Hello,

we recently purchased a used VNX5300 to support some lab workloads in a test environment we have running and I guess we didn't realize that the array software itself runs from the disks on the DPE which were obviously removed by the previous owner for data protection reasons. 

I guess is what we need to know is how can we obtain a copy of the latest block OE for block code to reinstall on the array and get it into a functional state? Seems silly to spend a few thousand on time & materials just to download a file for a system that is technically end of life. I was hoping someone out there might have a copy of OE for block & Unisphere saved somewhere and could help us out? not looking for any assistance with the install, just the means to get it done.
