DA-820 Series

Rackmount Computer

Quick Installation Guide

First Edition, October 2014

Overview

The DA-820’s main operating system is based on the lntel Core i7

CPU and QM77 chipset, which supports standard x86 platform. The

DA-820 has 2 VGA connections, 6 USB ports, 4 Gigabit LAN ports,

and 2 RS/232/422/485 3-in-1 serial ports, and is equipped with a

4 SATA disk interface and default support for RAID 0/1/5/10. In

addition, the DA-820 is specifically designed for substation

applications that require precise time synchronization and

products meeting the IEC 61850-3 standard. The flexible design

makes the DA-820 suitable for local SCADA, environmental

monitoring, video surveillance, protocol conversion, and PRP/HSR

redundancy applications, and the cybersecurity functionality

allows you to maintain secure network communications.

*The power input supports two types of power supply:

HV: 100 to 240 VAC/VDC

LV: 24 to 110 VDC

Connecting the Power

Use a screwdriver to loosen the terminal connector’s clamp screws.

Connect the power cord wires to the screws, and then retighten the

screws. The Power LED will light up to indicate that power is being

supplied to the DA-820, after which the BIOS will initialize the flash

disk module, causing the Storage LED to blink. It should take

about 30 to 60 seconds for the operating system to complete the

boot process.

Installing Removable Storage

The DA-820 has 4 hot-swappable 2.5” SSD/HDD storage trays

located on the front panel for installing additional storage drives.

Remove the screws on the trays to install the SSD/HDD storage

drives. RAID 0, 1, 5, and 10 are supported.

Configuring the Ethernet Interface

Linux users should follow these steps:

If you use the console cable to configure network settings for the

first time, use the following commands to edit the interfaces file.

First, make sure all network interfaces are offline before you

reconfigure the LAN settings:

MOXA:~# ifdown –a

Next, edit the network interfaces file; you may use a text editor of

your choice, but vi is the default editor on the DA-820-LX:

MOXA:~#vi /etc/network/interfaces

You may set the DA-820 for either dynamic IP addressing or static

IP addressing. For dynamic IP addressing, enter the following lines

into the network interfaces file:

# The primary network interface

auto eth0

iface eth0 inet dhcp

To configure an interface for static IP addressing, use the following

configuration. Each interface must be configured with separate

entries in the network/interfaces file; LAN1 corresponds to eth0,

LAN 2 corresponds to eth1, and so on for the remaining interfaces.

# The loopback network interface

auto lo

iface lo inet loopback

# The first LAN interface, LAN 1

auto eth0

iface eth0 inet static

address 192.168.3.127

netmask 255.255.255.0

broadcast 192.168.3.255

# The second LAN interface, LAN 2

auto eth1

iface eth1 inet static

address 192.168.4.127

netmask 255.255.255.0

broadcast 192.168.4.255

Exit vi by typing:

:wq

After the interfaces file has been configured, use the following

commands to reinitialize the network interfaces and activate the

new settings immediately:

MOXA:~#sync; ifup –a

Win7 users should follow these steps:

Step 1:

Go to Start Control Panel Network and Internet



Network Connections.

Step 2:

On the Local Area Connection Properties screen, click

Internet Protocol (TCP/IP) and select Properties.

Step 3:

Click OK after inputting the preferred IP address and

netmask.
