Switch 4210 52-port Front Panel The Switch 4210 52-port front panel provides 48 10/100Base-TX autosensing Ethernet ports, two 10/100/1000Base-T autosensing Ethernet ports, two 100/1000Base-X SFP ports (The 4 gigabit ports are all active), and one Console port. Each SFP port and the corresponding 10/100/1000BASE-T autosensing Ethernet port form a Combo port. For each Combo port, you can use either the SFP port or the corresponding 10/100/1000BASE-T Ethernet port at one time. The Switch 4210 52-port unit is displayed in Figure 16.
