we are now operating the switch device 'WS-C3750X-24T-L' now. but, this device was procured some ago. and also installed at remote site.
we need to check if this switch can have 10G interface with inter-connect server platform. when I get some show output it is like here.
NAME: "1", DESCR: "WS-C3750X-24"
PID: WS-C3750X-24T-L , VID: V02 , SN: ---------------------
NAME: "Switch 1 - Power Supply 0", DESCR: "FRU Power Supply"
PID: C3KX-PWR-350WAC , VID: V02L , SN: ---------------------
NAME: "Switch 1 - Power Supply 1", DESCR: "FRU Power Supply"

yes, it's kind of stacking x 2 C3750. when I see 'show ip int brief' then I can see the two 10G interface.
-omitted-
Te1/1/1 unassigned YES unset down down
Te1/1/2 unassigned YES unset down down
and I issued 'show interface te 1/1/1 capa' to dig in to see what capability it has.
TenGigabitEthernet1/1/1
Model: WS-C3750X-24
Type: Not Present
Speed: 10000
Duplex: full
Trunk encap. type: 802.1Q,ISL
Trunk mode: on,off,desirable,nonegotiate
Channel: yes
Broadcast suppression: percentage(0-100)
Flowcontrol: rx-(off,on,desired),tx-(none)
Fast Start: yes
QoS scheduling: rx-(not configurable on per port basis),
tx-(4q3t) (3t: Two configurable values and one fixed.)
CoS rewrite: yes
ToS rewrite: yes
UDLD: yes
Inline power: no
SPAN: source/destination
PortSecure: yes
Dot1x: yes
it is like above, I just need to confirm two things. is this switch can support 2x 10G interface with copper interface type?
Thanks.

The 3750 config shows "ghost" 10g interfaces. I.e. they show even when the ports are not physically preset.
The module that both Leo and Marvin mention comes in different varieties. Not all of them provide 10g ports, so even if you had one installed, you will still see "ghost" 10g ports that cannot be used. Only when you have a module that provides 10g ports, will you actually be able to use 10g ports. (BTW, there's often IOS minimums to use specific modules. [There can also be other requirements to use certain modules, although I don't thing any pertain to the basic 3750-X 10g capable modules. Always best to check datasheets, though.])

There is no module installed.

Thanks, so, this switch platform can have 2 X 10G interfaces as default, but, current switch doesn't have 10G SFP module installed? I thought this 10G can support copper type so it doesn't need SFP module, can you explain me a bit?

Your 3750X model has 24 ports of 10/100/1000 Mbps built-in.
There is a small slot on the right side that is optionally populated with a network module. Several versions are available, including one with 2 x 10 Gbps SFP+ ports.
Based on your output, on your switch that slot is not filled with anything (except probably a blank faceplate).
Unless and until you add a network module, you will only have 24 x 10/100/100 Mbps ports.
