Adding a Device to a Configured System

Introduction

When a Just Add Power system is configured - most often with JADConfig - ports on the managed Ethernet switch are setup to be connected to either a Transmitter or a Receiver.

Just Add Power often recommends that the switch should be configured for more Transmitters and Receivers than are currently present, with the expectation that the system will expand in the future.

Example: A system with 4 Transmitters and 6 Receivers is configured as a 6x8, allowing for 2 more Transmitters and 2 more Receiver to be added later.

When it comes time to add expansion devices, there are 2 options:

Option 1: Re-run JADConfig

Configure Switch and Devices through JADConfig in the same way that the system was originally setup. This will require:

  • Console connection to the switch
  • Wired network connection from the PC to port 1 of the switch
  • HDMI cables disconnected from all Transmitters

JADConfig must be used if the switch was NOT configured with expansion Transmitter and Receiver ports in mind.

Option 2: Manually Configure the Expansion Device

In order for the expansion device to communicate with the system, 4 things must occur:

  1. There must be a port on the switch configured for the expansion device
  2. The expansion device must match the system firmware
  3. The expansion device must match the system IP scheme
  4. The expansion device must match the system Mode (2G Mode or 3G Mode)

#1 occurred when JADConfig configured extra Transmitter and Receiver ports on original setup. If additional ports were not configured or the system details are not known, then JADConfig must be run again. Please use Option 1 to add devices.

#2-4 will be configured manually below.

Find System Firmware, IP, and Mode

The expansion device must match the system firmware, IP, and Mode to communicate properly. The JADConfig Report file - generated when the system was originally configured - has all of this information for the system and the expansion device:

Use Report File to find expansion device details
If you did not save the Report file, it is located on the JADConfig PC at \Program Files (x86)\Just Add Power\JADConfig\Reports named as the date and time that JADConfig completed.

Use the Report file to record these details about the expansion device based on the port it will be connected to. Expansion ports can be identified by the '??' at the end of the line. For this example we will be adding Receiver 13 in port 20:

  1. IP address - 10.128.0.14
  2. Subnet mask - 255.0.0.0
  3. Default gateway - 10.128.0.1
  4. Firmware version - A6.5.5
  5. Mode - 3G Mode because the system does not contain 2G devices (2GΩ/3G and 3G devices are in 3G Mode by default)

Connect the expansion device to the local network

To configure the expansion device, the PC must be able to access the web interface. To gain access to the web interface, the expansion device must be connected to a port on the local network.

Switch diagram with data ports

Connect the expansion device to one of the unconfigured (yellow) data ports on the Just Add Power switch to give it Power Over Ethernet (POE) and access to the local network. If there are no unconfigured data ports on the Just Add Power switch, connect the expansion device to another network switch. If no POE is present, use a compatible power supply to power the unit.

Find the expansion device IP and set PC IP to match

Connect the PC to the same network that the expansion device is connected to. This can be through one of the unconfigured (yellow) data ports on the Just Add Power switch or through another network switch.

Open the Bonjour Browser program to identify the current IP address of the expansion device. Go to the Web Server(HTTP) option. Look for a device with the name:

  • "HTTP on ast3-gateway" for a 2GΩ/3G or 3G Transmitter
  • "HTTP on ast3-client" for a 2GΩ/3G or 3G Receiver
  • "HTTP on ast-gateway" for a 2G Transmitter
  • "HTTP on ast-client" for a 2G Receiver

Bonjour Browser
Note: A device at default settings will have an IP of 169.254.X.X, subnet 255.255.0.0.

Go into the PC's network settings and set the IP on the PC to match the IP scheme on the expansion device. For an expansion device at default settings, set the PC IP to 169.254.100.100, subnet mask 255.255.0.0 (Default gateway can be blank)

Set PC IP

Access web interface to configure

Once the PC IP is set, open a web browser to the IP of the expansion device.

First, set the Mode on the device if needed. Go to the System tab --> Utilities bar. To set 2G Mode:

2gmode.sh

To set 3G Mode (default Mode on all 2GΩ/3G and 3G devices):

3gmode.sh

The device will reboot. Once it reboots, re-enter the web interface.

Apply 2G Mode

Second, select the Network tab to set the static IP Address, Subnet Mask, and Default Gateway that were recorded earlier. Select Apply.

Network tab

Third, go to the System tab --> Update Firmware bar. Browse to the firmware file that matches the firmware version recorded earlier and the hardware model of the expansion device. Select Upload. Once the update begins, it must not be interrupted.

Update firmware on Receiver

Finish

Once the device has updated. It can be removed from the data port and connected to the port on the switch that it was configured for. The unit is ready to function.
