Note GBICs are sold separately from the 1000BaseX modules. Cisco 
supports some approved third-party GBICs. For more information, 
refer to the Catalyst GigaStack Gigabit Interface Converter 
Hardware Installation Guide.
The GBICs fit through cutouts in the front of the module and plug into connectors 
on the module.
