EHG2008 is an industrial unmanaged Gigabit
switch with 8 RJ-45 ports. It is designed to work in the industrial
environment, such as in hazardous locations, where it complies with CE,
FCC, UL, RoHS and REACH standards.
EHG2008 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.
EHG2008 provides two redundant power inputs that can be
connected simultaneously to wide-range DC power sources. If one of the power
inputs fails, the other source acts as a backup to provide the EHG2008 the
power it needs.
The device also embeds an Packet Prioritization feature that
is advanced for unmanaged switches. The switch is able to read the QoS field
inside the VLAN tag of the packet, prioritizing those that are important to
reach the end device first, even during network congestion. This is vital in
Industrial Automation applications that are, for example, Profinet Based.
