The Switch 4210G 48-Port provides two interface module slots on its rear panel. Each slot is installed 
with a filler panel when the switch is shipped. You can select one or two interface modules for your 
switch as needed. See 
Optional Interface Modules on page 1-15 for the interface module models 
supported by the Switch 4210G, and see
