The EX45900 Series — a Slim and Powerful Hardened Unmanaged 5-port (4 x PoE) Gigabit Ethernet Switch


The EX45900 Series Hardened Unmanaged 5-port 10/100/1000BASE (4 x PoE) + 1-port 1000BASE-X Gigabit Ethernet Switch is a new release from EtherWAN. The PoE/PSE ports are IEEE802.at compliant, providing up to 30 watts per port. The EX45900 suits in applications such as machine vision industry, IP video surveillance solutions, and 802.11n WIFI connections, which require more bandwidth and packet priority setting however energy efficiency is mandatory.

Although unmanaged, the EX45900 provides IEEE802.3az Energy Efficient Ethernet (EEE) and IEEE802.1p Quality of Service (QoS). The hardware provides 24 / 48 VDC flexible redundant power inputs, and a DIP switch for port fault alarm, broadcast storm and jumbo frame features.

The EX45900 is with special circuit design for LAN port protection. The data ports can be fully secured when lightning strike occurs. This protection can be guaranteed no matter the power is given from a non-isolated or an isolated power supply unit.

The slim DIN-rail design of the EX45900 is good for space-sensitive installations. The front panel LED indicators display link, PoE status, power status, and alarm for easy monitoring.

The EX45900 Series offers the following benefits to users:

Two uplink ports available (1 x 10/100/1000TX + 1 1000SX/LX/SFP)
  • One Gigabit going into the switch port from the host and one Gigabit leaving the switch port towards the host.

Power over Ethernet on Gigabit Ethernet
  • No extra power cord needed for PD installations while larger bandwidth for data transmission can be expected as well.

Gigabit bandwidth
  • Better throughput rate to transmit larger packet size data.
  • Better interoperability and backward compatibility.
  • Connection with wireless AP or some bandwidth-demanded devices.

Jumbo Frame support
  • Carries up to 10K bytes of payload to increase throughput and network efficiency.

Green Ethernet
  • Complies with IEEE802.3az Energy Efficient Ethernet (EEE) standard to allow less power consumption during periods of low data transmission.

Quality of service (QoS)
  • 4 Priority markings are carried in Virtual Local Area Network (VLAN) tags that user can use existing resources efficiently and ensure the required level of service without reactively expanding their networks.
