Does HP lock the SFP ports on their switches?

I'm looking in particular at an HP E5406zl, but I imagine it's a policy across all their switches or all their switches at a particular level.

We're replacing an existing aging switch with a new model, I'd like to use some SFP units we have on hand that are not HP branded. Before I can commit to this, I need to know: does HP lock their switches to only supported HP-branded/keyed SFP units? This is a $6000 swing in the cost of the upgrade, and can be the difference in whether I'm allowed to do this at all, but before I can move I need to hear something definitive.

I don't think you'll get a definitive answer to this, as it will vary across models. Personally, I can confirm I've used generic gigabit SR SFPs with success in Procurve 5400, 5300 and 2600 series switches. However, a generic 10GbE GBIC in the 5400 failed quite quickly, though that wasn't longer after the 10GB module was released for that switch, so expect the generics might have come along a bit since then. In any case, if you buy generics you won't get any support from HP for them, which might be a bigger consideration. –  James Yale Oct 22 '12 at 13:57
    
@JamesYale my usual strategy is to buy just one pair of name-brand sfps, and if I have a connection issue use them at either end of the link in question for the duration of a support call. –  Joel Coel Oct 22 '12 at 14:13

I've used non-HP transceivers in 5400zl switches before. Your best bet it to get a small eval or sample and try it in your environment.

I also hope you're not paying retail for those 5406 switches :)

Perfect. This is a zl model, so that's exactly what I needed to hear. –  Joel Coel Oct 22 '12 at 13:51
    
I don't have a complete list, but I've used SFP cables as well. But seriously, you'll have to test before committing. –  ewwhite Oct 22 '12 at 13:53
