Front panel
Switch 4210s 18-port PWR each provide sixteen 10/100Base-TX autosensing
Ethernet ports, two 10/100/1000Base-T Ethernet ports, two 100/1000Base SFP
ports, and one Console port. Each SFP port and the corresponding
10/100/1000BASE-T Ethernet port form a Combo port. For each Combo port,
either the SFP port or the corresponding 10/100/1000BASE-T Ethernet port can be
used at a time.
