Overview
Introduction The four ConneXium Ethernet switches discussed in this guide are especially
designed to connect single devices or complete network segments in industrial
environments. They support Ethernet 10 MBit/s and fast Ethernet 100 MBit/s. The
switch modules support switched Ethernet networks in accordance with IEEE
standard 802.3 or 802.3u using copper and fiber optic technology. The switch
modules are mounted on a standard DIN rail.
The four ConneXium Ethernet switches discussed in this guide are described in the
following table:
The TP (copper) ports support half/full duplex and 10/100 Mbps autonegotiation,
autopolarity, and autocrossing. The fiber optic ports support full duplex.
Ethernet Switch Copper Ports Fiber Optic Ports Fiber Optic Type
499NMS25101 4 1 multi-mode
499NMS25102 3 2 multi-mode
499NSS25101 4 1 single-mode
499NSS25102 3 2 single-mode
Note: The multi- and single-mode capabilities of the modules are indicated by the
designations NMS (multi-mode switch) and NSS (single-mode switch) in their
respective part numbers.
