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

Rainer Blaes

Dear all,

we are trying to establish an uplink to a Cisco 2960 (48 ports of Gb  Ethernet

and two 10 Gb Ethernet SFP+ ports). At the Blade site there is one IBM  10 GBE

850nm SFP+ Transceiver (CRU 44W4408) in the first slot of the CVR-X2-SFP  and

at the Cisco 2960 site we used the CISCO SFP+ 10 Gb transceiver. But  there is

no link (electrical contact). What can we do next?

Many thanks for any hints!

Rainer

Rainer,

Are you using MM SPF and MM X2 at the chassis or SM?  Are you using the correct fiber patch?

since the 2960 is SFP+ and the chassis is X2 type optic, you need an LC to SC patch cord

Dear Reza,

excuse me I'm not an expert in the fibre cable tech but I think we used SM

between the Blade's Cisco CVR-X2-SFP and the Cisco 2960 10Gb port.

However do we need a LED to SC cord in this case?

Best regards, Rainer

You need LC to SC fiber cord.  If your optics are SM, then your patch cord needs to be SM also.

SC connect to the 3110 and LC connects to the 2960

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.
