The Switch 4210 26-port front panel provides 24 10/100Base-TX autosensing 
Ethernet ports, two 10/100/1000Base-T autosensing Ethernet ports, two 
100/1000Base-X SFP ports, 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.
