[c-nsp] switch with 2x 10GBASE-T interfaces

[Martin T]

Nikolay,
I'm afraid you are confusing this with C3KX-NM-10G module. Check the
table 3. C3KX-NM-10GT module is strictly 2x 10GBASE-T RJ45 ports(image
of the C3KX-NM-10GT: http://mcaf.ee/0bjty).

In general, "WS-C3750X-24S-S + C3KX-NM-10GT" seems to be a perfect
solution. WS-C3750X-24S-S has an "IP Base" image, which is enough
because I don't need advanced L3 features like EIGRP, OSPF, BGP and
IPv6 routing provided by "IP Services". WS-C3750X-24S-S is easily
upgradable thanks to StackWise Plus and StackPower technologies.
Supports dual redundant power supplies and in overall is a nice 1U
feature-rich switch according to specifications.

Just one hesitation with WS-C3750X-24S-S..is it possible to insert
1000BASE-T SFP's to first 22 ports(I would use last two SFP ports for
1000BASE-LX10 SFP's)? I mean 1000BASE-T SFP's have RJ45 connector
which is bit bulky and I'm not sure if it's possible to physically
insert 1000BASE-LX10 SFP's besides each other? Any experience with
this?


In addition, as I checked the 4900 series as well, do built in X2
ports(the ones in the chassis http://mcaf.ee/us1dt) in 4900M support
"TwinGig Converter Module"? According to documentation they don't. Any
experience with this?


regards,
martin
