ICP DAS USA ALX-9000 Series User Manual page 7

Besides the local I/O slots, ALX-9000 also provides several RS-232/RS-485/USB ports
and two Ethernet ports to connect with serial/USB I/O and Ethernet I/O devices.
Dual Ethernet Ports
ALX-9000 provides two Gigabit Ethernet ports. The two Ethernet ports can be used to
implement redundant Ethernet communication and separate Ethernet communication
(one for a global Internet, one for private Ethernet).
Dual Watchdog Timer
A system could be hanged up when the OS or the AP fails. There are two watchdogs
(CPU watchdog and Backplane watchdog) designed to automatically reset the
CPU/Backplane when the situations happen. The design will increase the reliability of
the system.
Redundant Power Inputs
To prevent the ALX-9000 from failing by the power loss, the power module is designed
with two inputs. The ALX-9000 can keep working even one power input fails, and
meanwhile, there is a relay output for informing the power failure.
Operating Temperature：
