시스코 4900M 시리즈 장비에는 위와 같이 슬롯에 모듈을 꼽을 수 있습니다.
10G 포트에 1G Gbic 을 사용하여 포트를 두배로 확장 할 수 있습니다.
10 Gigabit Ethernet and Gigabit Ethernet on the Same Half Card
The Cisco TwinGig Converter Module (Figure 6) converts a single 10 Gigabit Ethernet X2 interface into two Gigabit
Ethernet port slots that can be populated with SFP optics, enabling customers to use Gigabit Ethernet SFPs on the
same card in combination with 10 Gigabit Ethernet X2 optics. The Cisco OneX Converter Module is supported on all
10 Gigabit Ethernet modules of the Cisco Catalyst 4900M. The Cisco OneX converts an X2 interface into one SFP+
interface and uses the full range of Cisco SFP+ transceivers (Figure 7).

TwinGig Converter Module을 이용해서 위와같이 포트에 두개의 GBIC을 꽂아서 사용할 수 있다고 합니다.

I know I'm replying to an old post, but for the sake of folks getting here via google:
*May 1 14:35:06.899: %C4K_IOSMODPORTMAN-6-MODULEONLINE: Module 1 (WS-C4900M S/N: x Hw: 1.8) is online

Module 1: Built-in 8x 10G
Module 2: Left Module
Module 3: Right Module
Note the 4908-10GE card has 16 GigE interfaces defined for use with CVR-X2-SFP= (TwinGig), counting up in port number from where the 10G interfaces left off.

위와같이 되면 Te1/1 - Te1/8 , Te2/1 - Te2/8 은 사용하지 못하게 되며 ( 16개 )
대신 그 뒤로 GigabitEthernet 인터페이스가 차례로 생성되게 됩니다. ( 32개 )
