NETernity™ PMC941FX is a fully integrated unmanaged PMC Ethernet switch with four front panel 100BaseFX ports and four 10/100BaseTX ports routed to rear I/O plus 1 on-board NIC. It is designed to support the low-cost requirements of unmanaged switch applications and converging networks. The QoS technology allows low cost unmanaged switches to carry voice and data traffic without having to compromise the quality of its voice traffic by using the packet prioritization scheme. Packets are prioritized based upon their Layer 2 VLAN priority tag or the Layer 3 Type-Of-Service / Differentiated Services (TOS/DS) field. This priority can be defined as transmit and/or drop priority. In addition, card edge PCI systems can be accommodated using our PMC239 adapter for rapid prototype and development.

This product is no longer recommended for new designs.
