The ATOP EH2308-PR is an 8-port industrial unmanaged fast Ethernet switch with Profinet connectors. This switch is specifically designed to work in the industrial environment, such as in hazardous locations that comply with CE, FCC, UL and RoHS standards. The ATOP EH2308-PR protects itself from receiving too many 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. The ATOP EH2308-PR series provides two redundant power inputs that can be connected simultaneously to wide-range DC power sources. If one of the power inputs fail, the other live source can act as a backup to automatically provide power to the ATOP EH2308-PR.
