Combo interface
The S6520X-16ST-SI and S6520X-24ST-SI switches each provide two combo interfaces on the front
panel. Each combo interface contains an SFP+ port and a 1/10GBASE-T autosensing Ethernet port.
Only one of these two ports is active at a time.
An LSPM4G4T6P interface module provides two combo interfaces. Each combo interface contains
an SFP port and a 10/100/1000BASE-T autosensing Ethernet port. Only one of these two ports is
active at a time.
