ETHERNET ADAPTERS

ETHERNET-2 ADAPTER

The Ethernet-2 adapter was formerly known as the Ethernet adapter.

The Ethernet-2 provides direct support for two Ethernet (or 802.3) LAN connections. In the CyberSWITCH, this adapter provides both local and remote bridging of LAN data.

The Ethernet-2 incorporates an Intel i960 RISC processor executing at 33Mhz. When coupled with the integrated, high-performance Ethernet controllers, the adapter can operate at the maximum speed of the LAN (10Mbps). This is equivalent to a packet rate of 14,800 packets per second (pps).

The adapter has 2MB of DRAM, which allows it to execute sophisticated filtering and forwarding functions. The adapter maintains a large table of over 1000 entries for local MAC addresses.

The front of the adapter has two 15-pin AUI connectors. This provides direct connection for 802.3 transceivers, which accommodates 10Base5, 10Base2, or 10BaseT connectivity.

ETHERNET-1 ADAPTER

The Ethernet-1 adapter was formerly known as the Ethernet LE adapter.

The Ethernet-1 provides direct support for a single Ethernet (or 802.3) LAN connection. In the CyberSWITCH, this adapter provides remote bridging of LAN data.
