EH2308 with 8 RJ-45 ports for your
industrial applications. It designs to work in the industrial environment, such
as in hazardous locations, where it complies with CE, FCC, UL, and RoHS
standards. EH2308 is also available in an E-Mark certified version, that allows
this compact, powerful and cost-effective switch to be used in in-vehicle
applications.
EH2308 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.
EH2308 provides two redundant power inputs that can be
connected simultaneously to wide-range DC power sources. If one of the power
inputs failure, the other live source acts as a backup to provide the EH2308
power needs automatically
