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 2011/10/1 Nikolay Shopik <[email protected]>: > Martin, > > C3KX-NM-10GT allow you to install only two 10Gb SFP+ or 4 1Gbit SFP, or just > ony 10Gbit SFP+ plus 2 1Gbit SFP.
