DA-720 Series HW UM

Hardware Installation

Use two screws on the left side and two screws on the right side. Check to make sure that the four screws
are firmly attached to the rack.

ScrewsScrewsWiring Requirements
The following common safety precautions should be observed before installing any electronic device:•

Keep power wires and communications/signals wires in separate paths. If power andcommunications/signal wires must cross paths, make sure the wires are perpendicular at theintersection point.

•

Use the type of signal transmitted through a wire to determine which wires should be bundled together
and which kept separate. The rule of thumb is that wiring that carries similar electrical signals can bebundled together.

•

We strongly recommend that you label the wiring for all devices in the system for easy identification.

ATTENTION
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.

ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device.
Electrical Current Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum
ratings, the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, andconsequently the outer casing may feel hot to the touch.

Upgrading the BIOS
This section describes how to upgrade the BIOS.
IMPORTANTBIOS upgrades, if not done correctly, can permanently damage the computer. We strongly recommendthat you contact Moxa’s technical support staff for assistance to obtain all necessary tools and the mostcurrent advice before attempting to upgrade the BIOS on any Moxa device.

Step 1: Create a Bootable USB Disk
Before upgrading the BIOS, you must create a bootable USB RAM drive, which you can use as a system
rescue device. A useful software suite, Rufus for creating a bootable USB RAM drives can be downloaded at:https://rufus.akeo.ie/
To create a bootable USB disk using Rufus software, do the following:
1. Start Rufus and select the USB device that you want
to use as a bootable disk from the Device drop-downlist.
2. Select MBR partition scheme for BIOS or UEFI
computers to boot from a legacy BIOS or UEFI.
3. Select FAT (Default) from File system drop-downlist.
4. Select 16 kilobytes (Default) for Cluster size.
5. Enter a drive name under New volume label.
6. Select the Quick format, Create a bootable disk
using FreeDOS, and Create extended label andicon files format options.
7. Click Start to format and create the bootable USB
drive.

ATTENTION
We suggest you use a USB drive with under 2 GB disk space, as larger USB drives may not support FAT fileformat and consequently fail to boot.

Step 2: Prepare the Upgrade File
You must use the BIOS upgrade installation file to upgrade the BIOS. Contact Moxa’s technical department
for assistance.
1. Get the BIOS upgrade installation file. The file name should have the following format:
682AxxSx.exe (xx refers to version numbers).
2. Copy the file to the Bootable USB Disk.

3-15

DA-720 Series HW UM

BIOS Setup

Step 3: Run the upgrade program on the DA-720 Computer
1. Reboot the computer, press F12 while booting up to enter the Boot Manager
2. Select USB Disk as the first boot source. Press Enter to continue.

3. When the boot up process is complete, the DOS screen is displayed. Go to the directory where theupgrade file is located. For example, if the upgrade file is stored in the DA-720 folder, type cd DA-720.

C:\cd DA-720
4. Run the upgrade program by typing DA-72010017.exe. Please note that the upgrade filename will varydepending on the computer versions.

C:\ DA-720>DA-72010017.exe
5. Wait until the upgrade process is complete.

3-16

DA-720 Series HW UM

BIOS Setup

6. When the upgrade is finished, the computer will automatically reboot. You can check the BIOS version
on Main page of the BIOS Setup to confirm the upgrade.

ATTENTION
DO NOT switch off the power supply during the BIOS upgrade, since doing so may cause the system tocrash.

Safety Installation Instructions

A. RTC Battery Warning
CAUTION: There is a risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries
according to the instructions.

B. Fuse Warning
CAUTION: For continued protection against fire, replace only with same type and rating of fuse.

C. Rackmount Warning
The following or similar rackmount instructions are included with the installation instructions:(1) Elevated Operating Ambient: If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than the room ambient temperature.
Therefore, consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
(2) Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
(3) Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition
is not achieved due to uneven mechanical loading.
(4) Circuit Overloading: Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing thisconcern.
(5) Reliable Grounding: Reliable grounding of rack-mounted equipment should be maintained. Particularattention should be given to supply connections other than direct connections to the branch circuit (e.g., byusing power strips).
