5. Setup and Installation

5.1 Mounting the Device

The AWK-3131A-US supports DIN-rail mounting. Ensure the mounting surface is stable and provides adequate ventilation.

1. Attach the DIN-rail kit to the rear panel of the device using the provided screws.
2. Hook the top of the DIN-rail clip onto the DIN rail.
3. Push the bottom of the device towards the DIN rail until it snaps into place.

5.2 Antenna Installation

Carefully screw the two provided antennas onto the RP-SMA connectors labeled 'A' and 'B' on the front panel. Ensure they are finger-tight but do not overtighten.

5.3 Power Connection

The device supports redundant DC power input and Power over Ethernet (PoE).

• DC Power: Connect a compatible DC power supply to the terminal block. The device supports dual power inputs (PWR1 and PWR2) for redundancy.
• PoE: If using PoE, connect a PoE-enabled Ethernet cable to one of the LAN ports. Ensure the PoE source meets the device's power requirements.

After connecting power, the PWR1/PWR2 or PoE LED should illuminate green.

5.4 Network Connection

Connect Ethernet cables from your network devices (e.g., switches, computers) to the LAN ports on the AWK-3131A-US.

5.5 Initial Configuration

The device can be configured via a web browser or the RS-232 console port.

• Web-based Management:
  1. Connect your computer to a LAN port of the AWK-3131A-US.
  2. Configure your computer's IP address to be in the same subnet as the device's default IP (e.g., 192.168.1.x).
  3. Open a web browser and enter the device's default IP address (refer to the Quick Installation Guide for the default IP).
  4. Log in using the default username and password.
• Console Management:
  1. Connect a serial cable from your computer to the RS-232 console port.
  2. Use a terminal emulation program (e.g., PuTTY) with appropriate serial settings (e.g., 115200 bps, 8 data bits, no parity, 1 stop bit, no flow control).
  3. Log in using the default username and password.

It is highly recommended to change the default login credentials immediately after initial access.

6. Operating the Device

The AWK-3131A-US can operate in various modes to suit different network requirements.
