MachineQ Gateways

Device Overview 

The device's label on the rear battery door contains the DEVEUI/Node ID, a unique 16-character hexadecimal value. Please note this as it is necessary to identify the device. 

The default device configuration is as follows:

• Temperature / Humidity / Push Button enabled.
• Reporting period of 6 hours.
• Sampling period of 2 minutes
• Temperature Report Delta: 1 ℃
• Humidity Report Delta (Relative Humidity): 5%

Gateway Status

The first step in troubleshooting MachineQ gateways is to identify the current status of the malfunctioning gateway. The physical LED status indicators on the gateway will provide valuable information for your troubleshooting workflow.

Gateway Status Indicators

The articles below explain each gateway model's LED status indicators and the significance of their color or blink pattern.

There are four lights on the front of the Gateway that will power on or off depending on its status:

1. First Light: Power Status
   Blue: Gateway is powered on
   Off: Gateway is not powered on
   Blinking blue slowly: Initial power up
   Blinking red fast: Gateway has an internal error
   Alternating red and green blinking slowly: Firmware update
   
   
2. Second Light: Cellular Connectivity Status
   Blue: Cellular connectivity is active
   Off: Cellular connectivity is not active
   Red: The gateway was not able to connect to the configured network.
   Blinking Green Slowly: In AP mode. This will turn off after 20 minutes (not applicable for LTE/ETH models)
   
   
3. Third Light: Ethernet Connectivity Status
   Blue: Gateway is plugged into a network switch
   Off: Gateway is not plugged into a network switch
   Red: Ethernet is plugged in, but cannot connect to the network
   
   
4. Fourth Light: Sensor Connectivity Status
   Blue: Gateway can connect to the internet
   Red: Gateway cannot connect to the internet

A Gateway that has been installed successfully, is indicated by the light configuration.

If the gateway has been successfully installed, the following lights should display:

First Light: Blue

Second Light: Either Blue or Off

Third Light: Blue

Fourth Light: Blue

Troubleshooting

Once the gateway's status is understood, it becomes much easier to troubleshoot the gateway.

Power Cycle
This should always be the next step in the troubleshooting process. A power cycle is the process of removing power from the gateway for 30 seconds and then restoring power, which will often resolve connectivity issues.

Note: Depending on the gateway model, the boot sequence may take multiple minutes after a power cycle.

Connectivity

If all lights are BLUE or the 1st, 3rd, and 4th are BLUE:
The Gateway needs to be power cycled.

1. Power cycle the Gateway by unplugging the power cable from the Gateway.
2. Wait 30 seconds and plug the power cable back in.
3. The four lights will start flashing. Wait 5-10 minutes until the lights have stabilized.
4. If all lights are blue or the 1st, 3rd, and 4th are blue, check the status of your Sensors in Zenput.

If the 4th light is RED:
The Gateway is not connected to the internet.

1. Check the network cable that is plugged into the Gateway and your network switch and ensure that it is plugged in.
2. If the network cable is plugged in and the 4th light is still red, this means that the port you have it plugged in to does not have an active internet connection.
3. Locate and plug the network cable into a different port or a different network switch.
4. Wait 5-10 minutes to see if the 4th light turns blue.
5. If it turns blue, then the Gateway is able to connect to the internet. Check the status of your Sensors in Zenput

Wireless/Cellular Backhaul

If using wireless/cellular as primary backhaul, verify that the status LED on the gateway is illuminated and the color matches the proper status. If the gateway is not communicating, remove power from the gateway, remove and re-install the SIM card, and then re-apply power to the gateway.

Ethernet

If using ethernet as primary backhaul, confirm that the gateway is connected to a network switch supplying IP addresses via DHCP. In addition, verify that the status LED on the gateway is illuminated and the color matches the proper status.

A simple test to verify DHCP is available is plugging in another IP device such as a laptop computer and verifying it receives an IP address. You can also verify that the activity indicator on the network switch is illuminated to verify packets are flowing when a device is plugged in.

Note: Ethernet cabling contains several cable pairs. Faulty cable terminations at either end of an ethernet cable are a common cause of ethernet gateway communication issues.
