The device supports two groups of LAN by-pass function through watchdog timer and GPIO pin definitions. The system's Intel 82573 LAN chips support fail-over, load-sharing, and load-balancing functions.
The system provides four USB 2.0 ports -- two on the front panel, and two internally on pin headers. An RS232 DB9 console port is also available on the front panel; the BIOS can be be redirected to the console port for headless operation, the company says.
