Quad-Port Realtek RTL8100C 10/100 Ethernet PCI Card

The P811B-4R is a perfect quad or 4 port Ethernet card for a router or a server, to implement an embedded VPN, firewall or router requiring only one PCI slot. It has one (1) built-in miniPCI slots, sharing with the 4 LAN ports. Wireless capability can be easily expanded with 802.11b/g/a miniPCI adapters.

  • PCI bridge chipset: PLX PCI 6152 33BC 33MHz/32bit PCI bridge
  • Compliant to PCI-2.2 standard
  • Four (4) RJ-45 LAN ports on board based Realtek RLT8100C 10T/100T . (Recognized as four independent Ethernet ports)
    • Supports 10Mb/s and 100Mb/s Fast Ethernet
    • IEEE 802.3 10BaseT, IEEE 802.3u 100BaseTX Fast Ethernet
    • Supports Full Duplex Flow Control (IEEE 802.3x)
    • Supports Wake On LAN (PME) function
    • Supports PXE and RPL boot function depending on the main board's BIOS support
  • One (1) miniPCI sockets support Type IIIB only and share with 4th LAN Port. Note: If the miniPCI is used, the corresponding Ethernet port must be disabled.


  • A computer running Linux with the following recommendations:
    1. 400Mhz x86 compatible CPU
    2. 128M RAM
  • PCI slots.
    1. 1 x PCI slot for the main quad-port LAN board (5V)
  • Configurations (jumper setting):
    1. Four (4) Ethernet ports.
      • J1 OFF, J2 ON, J3 OFF, J4 ON
    2. Three (3) Ethernet ports, one (1) MiniPCI
      • J1 ON, J2 OFF, J3 OFF, J4 ON (MiniPCI1 enabled, LAN4 disabled)
