Optional Interface Modules
The Switch 4210G (excluding Switch 4210G NT 24-Port and Switch 4210G NT 48-Port) provide two
interface module slots on the rear panel. You can select the interface modules in
interface module slots on the rear panel. You can select the interface modules in
as needed.
The Switch 4210G support IRF, requiring physical connections between devices. The 10 GE ports of
the supported interface modules support IRF, allowing you to connect the switches through these 10 GE
ports for IRF implementation.
