interrupt for multiple, back-to-back incoming packets, preserving host CPU cycles.

Dual DMA Channels

The PCI interface on the ITI-5100G/GF adapter contains two independent DMA channels for simultaneous read and write operations.

ASIC with Embedded RISC Processor

The core control for the ITI-5100G/GF adapter resides in a tightly integrated, high-performance ASIC. The ASIC includes dual RISC processors. This provides the flexibility to add new features to the card and adapt it to future network requirements via software download. This also enables the adapter drivers to exploit the built-in host off-load functions on the adapter as host operating systems are enhanced to take advantage of these functions.

Diagnostic Support

An ITI-5100G/GF adapter RISC CPU runs on-board diagnostics at power-up.

Physical Description

Figure 3: ITI-5100GF adapter faceplate

The faceplate of the ITI-5100GF adapter has one 1000Base-SX fiber-optic connector for connecting the adapter to a Gigabit Ethernet segment. There are also two LEDs: one to indicate link status and one for data transfer status.

Once the adapter hardware and its driver software have been properly installed on your system, the LEDs will signal the following adapter states:
