I have 4 new Westell A90-ES8008g Ethernet Managed 8 port Switches
Westell eSmartES ES8000 Series Industrial Managed Ethernet EdgeSwitch
The first platform in this family is the eSmartES[tm] ES8000 series of Managed Ethernet EdgeSwitches. These managed switches are designed especially for ``edge'' applications, deploying the latest in reliability and security for harsh environments, on the perimeter of the network where Smart Grid and industrial devices are connected.
The eSmartES platform features the Westell Edge Operating System (WEOS), Secure Web Management GUI and CLI interfaces, SNMPv2,v3 management, 802.1p QoS Prioritization, Tag-based VLANs, IGMP Snooping and IGMP-L2 multicast management, port security, and network redundancy options including STP, RSTP, and MSTP for fault recovery in rings and meshes.
In the 8 port configuration, ports 7 and 8 are 10/100/1000Mb ports. Ports 7 and 8 can also be configured as optical FE-100FX or GigE ports populated with either a pair of STs, SCs, or LCs interfaces.
The ES8000 eSmartES switches are ideal for building a switched, hardened, Ethernet network infrastructure, connecting edge devices such as SCADA telemetry radios, Programmable Logic Controllers, and cameras with upstream switches or routers. Designed for use in industrial and heavy-duty outdoor applications such as power utility substations, video surveillance systems, and traffic control monitoring, the hardened ES8000 handles stressful workloads.
The ES8000 platform's industrial design features include an extended operating temperature range of -40 to +85°C (-40 to +185°F), redundant DC power of either 24Vdc or -48Vdc power supply inputs for high availability applications requiring dual power inputs, and provides a high level of immunity to electromagnetic interference and heavy electrical surges. The ES8000 is packaged in a rugged, galvanized steel enclosure that allows either backboard, DIN-rail, or wall mounting for efficient use of cabinet space. It can also be rack mounted in the optional 1RU rack mount bracket.
