Hello,
I saw a posted dated back in 2006 about this, I was hoping there are updates / changes? We just purchased a 5410zl setup, with the 4 port x2 10gbe module, and from what I can see none of our existing hardware will work with it. On cisco's you could ignore the messages and still use it (or in this case we would use cisco gbics on hp). From what I can see all of the HP stuff is crazy over priced (far more than what we were paying for cisco x2 transceivers). Payig $2,500 for a single x2 transceiver seems ridiculous.
Anyhow, I just wanted to see if there are any options, if not I guess I will need to dump the idea of using HP's within our network. Thanks for your time!
