NuPRO-E320
Gigabit Ethernet
The NuPRO-E320 uses two Intel® 82574L Gigabit Ethernet con-
trollers (NuPRO-E320LV supports 1x LAN only) connected to the
PCI-E x1 bus of the ICH10. Operation at data rates of 10/100/1000
Mbps, wake on LAN and PXE are supported.
Serial ATA II technology
Storage is efficient and secure with the Serial ATA interface. Utiliz-
ing the Intel® ICH10, the NUPRO-E320 supports up to four Serial
ATA devices capable of reading/writing data at up to 3 Gbps. The
SATA specification improves chassis airflow via thinner and more
flexible cables with lower pin count.
Universal Serial Bus (USB) 2.0
The NUPRO-E320 incorporates the Universal Serial Bus (USB)
2.0 specification that increases peripheral connection speed from
12 Mbps (USB 1.1) to 480 Mbps. USB 2.0 is backward compatible
with USB 1.1.
Hardware monitoring
A built-in, proactive hardware monitoring system in the ASIC mon-
itors the CPU temperature, system fan rotations, and voltage lev-
els to prevent overheating and/or component damage, effect
timely failure detection, and ensure stable supply of current for
critical components.
Watchdog Timer
The watchdog timer (WDT) monitors system operations based on
user-defined configurations. The WDT can be programmed for dif-
ferent time-out periods, such as from 1 to 255 seconds or from 1 to
255 minutes. The WDT generates a reset signal, then a reset
request, after failure to strobe it within the programmed time
period. A register bit may be enabled to indicate if the watchdog
timer caused the reset event. The WDT register is cleared during
the power-on sequence to enable the operating system to take
appropriate action when the watchdog generates a reboot.
