ATOP EH2304-PR - 4-Port Fast-Ethernet Switch
Compliant with CE, FCC, UL, and RoHSII standards, the EH2304-PR is a Fast Ethernet switch in a slim metal housing with 4 RJ-45 ports with Profinet connectors. It is designed to work in industrial environments and hazardous locations. The EH2304-PR is protected from receiving over broadcast packets. During normal use, broadcast packets will be forwarded to all ports, except the source port. However, it will discard broadcast or multicast packets if the number of those packets exceeds a threshold in a preset period of time. When the preset period expires (about 800ms), it will then resume receiving broadcast or multicast packets until the threshold is reached again. There are 2 redundant power inputs that can be connected simultaneously to wide-range DC power sources. If one of the power inputs fails, the another live source acts as an automatic backup to provide the EH2304-PR power.
