1 Introduction
1.1 Switch Description
The LB4M is a modular Gigabit Ethernet backbone switch designed for adaptability and
scalability. The Switch can utilize up to 48 Gigabit Ethernet ports to function as a central
distribution hub for other switches, switch groups, or routers. The one built-in 1000/100/10
Ethernet ports for out of service. The LB4M also provides SFP+ interfaces for 10-Giga port on
the daughter board. The number of 10-Giga ports depend on selecting daughter board.
