Blade HS22 + Cisco 3010X with Cisco CVR-X2-SFP: Uplink to Cisco 2960?

Have you checked the switches on both sides to make sure that the devices recognize the SFPs you've inserted, and haven't kicked them out for whatever odd reason that they will?

ie. show log show int te 0/1 capabilities

A small progress: We replaced the 10(!) Gb SFP+ Transceiver in the CVR- X2-SFP V02 converter by

a 1 (ONE) Gb SFP and connected it to a 1Gb port of our 2960 switch. Now we have a link I mean there

is now the green light on at the 2960 port.

But still we can't communicate from outside with one of our blades. We are also worry about the fact not

to see the 3110x 10Gb external uplink port by the Cisco Network Assistant. There are only 16 Gb ports

plus 1x fa0. Very strange.

The CVR-X2-SFP is designed to adapt 10G X2 ports in specific cisco switches to take one or two SFPs (1 gig), NOT SFP+ (10 gig), so I don't think that will work.

See

If you've got an X2 slot, you'll need an X2 tranceiver if you want 10 gig.

So long as what you're plugging it into supports it...
