The EH7508 Series is a highly reliable and fault-tolerant Industrial Managed PoE Ethernet Switch. It equips up to eight
10/100BASE-T(X) RJ-45 ports and up to four 10/100/1000BASE-T(X)/FX RJ-45 and SFP ports. With its high performance switching
capacity, EH7508 Series provides network redundant self-recovery mechanism is less than 20ms on full load which allows you
to scheme a reliable Ethernet network by building a redundant ring topology as your back-up solution. With a Multifunctional
web dashboard, EH7506/08/12 Series offers intelligent features such as Quality of service (QoS), Virtual LAN (VLAN), IGMP, Port
mirroring and security. To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify,
authenticate and authorize users. EH7508 support user account, password policy, and authentication interface managements
functions that comply with IEC62443 standard.

The EH7508 Series is designed for Industrial rugged applications. It equips a 5-pins terminal block to provide dual redundant
power inputs with Reverse Polarity Protection and two sets of relay which allows field engineers to build up a stand-alone fault alarm
system. Its IP30 housing protection, wide operating temperature of -20 to 70°C and DIN-Rail mounting capacities are liable to do
most industrial filed applications.

Being Profinet CC-B v2.33 certified, this switch Series is Automation and IoT ready. Profinet allows wired and wireless combinations
for an array of connectivity options, providing a more effective backbone for your automation operations.
