Hi,
I need to connect one sw3750E with two 3750X , with Uplinks at 10 GBps. My doubt is the next:
Switch 3750E has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules.
Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ???? the other SFP slot is disabled automatically?
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module is considered, this will be connected to SW3750E by means of SFP-H10GB-CU5M.
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.
is it right this options ?

Hi,
It depends of what kind of TwinGig adapter you have for 3750E. There are 2 kinds:
- one that converts a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet SFP ports. This is
CVR-X2-SFP. If you have this, it will not help you!
- the one that you need is CVR-X2-SFP10G. This converts a 10 Gigabit Ethernet X2 port into a 10 Gigabit Ethernet SFP+ port. In this way you can use SFP-H10GB-CU5M to connect to the other 3750X switches.
More detail about the CVR-X2-SFP10G module:

and take a look at the 10-Gigabit Ethernet transceiver Modules Compatibility Matrix:
I hope it helps,

Hi Bogdan,
Thanks a lot for your answer and tips. You clear my doubt.
based on the info the solution will be:
3750E side : 2 CVR-X2-SFP10G + 2 SFP-H10GB-CU5M ( I want to set an etherchannel)
3750 X side : network module C3KX-NM-10G
My last doubt is why in dynamic configutarion tools the converter module CVR-X2-SFP10G is not shown in converter module option 3750E switch.
the only option are CVR-X2-SFP-2, CVR-X2-SFP-1, CVR-X2-SFP-NONE.
thanks once again for your help.
regards

Great!
My first impulse was to write that you can't.
But I've said...hmm..let's check:). And then I've found out from the compatibility matrix about that X2 Converter to SFP+.
I don't know why doesn't show in dynamic config.:(
Just take care that you've said you have 2x3750X conecting to 1x3750E!:) In this chase you can't make an etherchannel, unless those 3750Xs are in a stack.
If you have 1x 3750X and 1x 3750E(with 2 CVR and 2 SFP), then...etherchannel !:)
Glad to help,
Bogdan

Hi Bogdan,
I really appreciate your time for answering this case.
In fact there would be 2 switches 3750E (in a stack) and 2 switch 3750X, that`s why I guess I can set an etherchannel.

What is the distance between the two switches?
You can use a 3 meter StackWise cable (CAB-STACK-3M)

Hi Leo,
you mean to set an stack between 3750E an 3750X switches?
3750E switches will have IP services or IP base but 3750 X will have LAN base.

Oh. Too bad.
