Replacing Procurve 4000M and have questions regarding new Fiber module

[mlchris2]

I currently have 2 x 4000m and plan on replacing at least one of them, possibly both.

unit 1 is in my server room and has 2 x ProCurve Switch Gigabit-SX Module (J4113A). Unit 2 is in a networking closet on another floor and has 1 x ProCurve Switch Gigabit-SX Module (J4113A).

My plan currently is to replace Unit 1 with another ProCurve (unknown which model, but def going to be Gigabit interface). I dunno if I'm going to replace Unit 2 at this time. I was searching around and not really sure which Fiber module I can use. I'm leaning towards the 4208vl, possibly a 2910al series.

After some research, would I purchase HP ProCurve Switch vl 1-Port 10-GbE X2 Module (J8766A) and HP ProCurve 10-GbE X2-SC ER Optic (J8438A) or HP ProCurve 10-GbE X2-SC SR Optic (J8436A)????

Because my current Fiber transceivers are 1000-Base, will something in the 10-GbE be compatible with my current Fiber? Is this even relevant???

I have been trying to get in touch with HP Sales for a few days but haven't received a response. Can someone help me? I hope I gave you enough info or asked the right questions. Im new to Fiber connectivity as well.

The 10Gb ports do not autonegotiate down, so it's 10Gb or nothing. If your replacing both switches for ones that will support 10Gb connectivity, we'll need to know what your fiber optic cable is in regards to either multi-mode or single-mode and distance.

Hope that helps.

My fiber is Multi-mode and distance I'm unsure of at this point.

I finally got a call back from HP Sales and they got me straight on the whole GBIC and transceivers.

I figured the 1GB ports dont autonegotiate, so rather than purchasing 4 new switches, I found a model of router that has the Gigabit SX GBIC.

thanks for the help
