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:
