The Dual/Quad 10/100-TX Mb/s Ethernet Adapter provides up to four Ethernet connections over twisted pair media. Options are available for Front-Panel RJ45 accessibility, or Rear I/O accessibility via a VITA 36 PIM module. The card is built around Intel 82551ER Ethernet controllers that provide an integrated media access controller (MAC) and physical layer
(PHY) for operating at either 10 Mb/s or 100 Mb/s. The 82551ER provides full-duplex operation at both speeds.
