Switch 4210 18-port Front panel
The Switch 4210 18-port models provide 16 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.
