Safety Approvals
CE Marking
FCC Class B
FCC Compliance
This equipment has been tested and complies with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. If not installed and used in accordance with proper instructions, this equipment might generate or radiate radio frequency energy and cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Shielded interface cables must be used in order to comply with emission limits. iii
Safety Precautions
Before getting started, read the following important cautions.
1.
Be sure to ground yourself to prevent static charge when installing the internal components. Use a grounding wrist strap and place all electronic components in any static-shielded devices. Most electronic components are sensitive to static electrical charge.
2.
Disconnect the power cords from the NA347 before making any installation. Be sure both the system and the external devices are turned OFF. A sudden surge of power could ruin sensitive components. Make sure the NA347 is properly grounded.
3.
Do not open the system’s top cover. If opening the cover for maintenance is a must, only a trained technician is allowed to do so. Integrated circuits on computer boards are sensitive to static electricity. To avoid damaging chips from electrostatic discharge, observe the following precautions:
Before handling a board or integrated circuit, touch an unpainted portion of the system unit chassis for a few seconds. This will help to discharge any static electricity in your body.
When handling boards and components, wear a wrist-grounding strap, available from most electronic component stores.

AMI BIOS Setup Utility
The AMI BIOS provides users with a built-in setup program to modify basic system configuration. All configured parameters are stored in a battery-backed-up RAM (CMOS RAM) to save the setup information whenever the power is turned off. This chapter provides users with detailed description about how to set up basic system configuration through the AMI
BIOS setup utility.
3.1 Starting
To enter the setup screens, follow the steps below:
1.
Turn on the computer and press the <Del> key immediately.
2.
After you press the <Delete> key, the main BIOS setup menu displays. You can access the other setup screens from the main BIOS setup menu, such as the Chipset and Power menus.
3.2 Navigation Keys
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS setup utility hot keys can be used at any time during the setup navigation process. These keys include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on.
Note: Some of the navigation keys differ from one screen to another.

LAN Bypass Configuration
About LAN Bypass
What is the LAN by-pass meant for NA347 Series It doesn’t have any down time in network connections for two other network segments (LAN1 and LAN2) 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.
GPO control
It acts like a switch of the application software. You can enable the hardware relay feature through the GPO 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”.
Note:
The LAN bypass function is depending on BOM configuration and BIOS setting. If the status is “Low Level GPO”, LAN Bypass function will still be started even when power supply is normally input. The default setting is “High Level GPO” that LAN Bypass function is not working when power supply is normally input.
