Ethernet Switch Card

December 1, 2011

Ballard Technology (Everett, WA) has introduced the MPR-ES-1, a 10-port managed/unmanaged Ethernet switch PMC for embedded use. The rugged COTS switch is suitable for both conduction and convection (air) cooled systems.

The MPR-ES-1 Ethernet switch includes two Gigabit ports and eight 10/100 Mbps ports. One Gigabit port routes directly to the integrated Ethernet controller and provides the host computer with a direct connection to the switch for system expansion. The second Gigabit port can act either as a straight 1 GB path for the host single board computer, as a high-speed uplink to other switches, or as a standard 10/100/1000 Mbps port. The CCPMC form factor allows integration with modern embedded computers, including VME, VME-64, cPCI, and VPX systems.

The MPR-ES-1 combines a Marvell® switch controller with onboard magnetics. It provides IEEE 802.1X MACbased authentication and support for up to 8K MAC address entries. Management functions include VLAN, QOS, and ingress/egress limiting. In addition, the switch includes health monitoring and diagnostic features such as Built-in Test (BIT), temperature monitoring, port mirroring, and Virtual Cable Tester™.
