APPENDIX A
ENABLING LAN BYPASS FEATURE
What is the LAN by-pass meant for
NA-330 Series
? It doesn’t have
any down time in network connections for two other network segments
(LAN3/LAN4 and LAN5/LAN6) when any fetal errors occur to this
device.
The LAN by-pass feature covers three levels as below:
1. Power
loss
While the AC power loss occurs to this device, the LAN1 and
LAN2 still can communicate with each other through
hardware relay like as a short cut between two segments. If
the power inlet can be normally done, the relay will turn to
another correct position.
2. GPIO
control
It acts like a switch of the application software. You can
enable the hardware relay feature through the GPIO control
through the application programs. Then, the software solution
provider can be more flexible to make it close with the
program.
3. WDT (Watchdog Timer)
The hardware supports the WDT (Watchdog Timer) function.
While time-out happens after a defaulted period, the WDT will
reset the system or make a short cut for two specific
segments by hardware relay.
Note: Please refer to BIOS “WDT function selection”.
The sample codes for the above features can be found
in the CD, and they are only for customers’ reference as
remarked.
