Features and Benefits
100Mbps switching services for factory automation Ethernet LANs
LBH08z/LBH18x Switches provide Fast Ethernet switching on all ports.
They perform high speed filter/forward operations on the traffic, giving
each port’s segment a full 100Mbps (or 10 Mbps) of bandwidth.
Option for one “future-proof” fiber backbone port connector,
Model
LBH18x
Built-in fiber ports may be ordered with 100Mbps full-duplex multi-mode
SC, LC and single-mode SC and LC connectors.
Model LBH08x with all RJ-45 (copper) ports
RJ-45 ports provide twisted pair segment connections, with auto-
negotiation and auto-cross MDI-MDIX functionality. All RJ-45 ports are
capable of half- or full-duplex.
Installation is “Plug and Play”, operation is transparent to software
The LBH08x/LBH18x operates as a hardware switch, only forwarding
those packets from each domain that are needed on the other domains.
Internal address tables are self-learning, enabling users to change port
connections or 10/100 domains without affecting operations.
Heavy-duty design for Industrial Ethernet and extended
temperature operation
Fiber ports take more power than copper ports, but the LBH08x/LBH18x
Series design provides for this with heavy-duty components. The
LBH08x/LBH18x is designed for industrial use, is an enclosed
convection-cooled package, and is UL rated at -25°C to 60°C ambient
sustained
temperatures.
