Chapter 2: Overview
Optional Modules for LGB2118A and LGB2124A
On the LGB2118A switch, Ports 17–18 are SFP fiber module ports. On the LGB2124A, Ports 21–24 include two types of media—
TP and SFP Fiber (with LC connectors); they support 10-/100-/1000-Mbps TP or 1000-Mbps SFP Fiber with auto-detect function.
