Installing Switches for an IRF
The Switch 4210G 24-Port, Switch 4210G 48-Port, Switch 4210G PWR 24-Port, and Switch 4210G
PWR 48-Port support the IRF function. You can install IRF-capable interface modules to connect
multiple switches through the 10 GE ports to form a logical entity, thus to establish a new intelligent
network with high reliability, expandability and manageability.
