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 44W440 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

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.

Regards, Rainer
