2-4 Fiber Port
HMG-1648P & HMG-1648EP is equipped with 4 x 100/1000Base SFP fiber port gives users more flexibility in
choosing fiber modules to fit the existing network structure on the plant floor.
2-5 Console Port
HMG-1648P & HMG-1648EP has an asynchronous terminal console port for local management via a serial
terminal. The terminal provides management via a CLI (Command Line Interface) which will be familiar to many
networking engineers. For most users, the CLI can be used to initially configure TCP/IP access so that further
configuration can be completed via the GUI (Graphical User Interface) and any web browser.
