Basic Troubleshooting check for LTE Nodes when Unreachable

This document outlines the standard operational workflow to establish a direct local SSH connection to an iNode device and extract cellular interface diagnostics (wwan) for remote troubleshooting.

 1. PREREQUISITES & REQUIRED TOOLS

  • Laptop with an RJ45 Ethernet port (or USB-to-Ethernet adapter).
  • CAT5e/6 LAN cable.
  • Terminal application (Command Prompt, PowerShell, or Terminal).
  • Designated SSH Private Key file (.pem format).

2. PROCEDURE

Step 1: Physical Connection

  1. Power on the iNode device.
  2. Connect one end of the Ethernet cable directly into the Management/LAN port of the iNode.
  3. Connect the other end directly into your laptop.

Step 2: Configure Laptop Network Interface

Set a static IP address on your laptop's Ethernet adapter:
Parameter Configuration Value
IP Address 192.168.192.10
Subnet Mask 255.255.255.0 (or /24)
Default Gateway 192.168.192.168

Step 3: Establish SSH Session

  1. Open Command Prompt or Terminal on your laptop.
  2. Run the following command (replace <Private_Key> with the full file path with SSH Key file name):
Command:
ssh -i <Private_Key> iotium@192.168.192.168

Step 4: Execute Diagnostic Commands

Once authenticated and connected to the iNode CLI prompt, execute:

Command:

show interface wwan --verbose

Step 5: Data Capture & Verification

  1. Capture a clear, full-window screenshot of the CLI screen displaying the output.
  2. Ensure the screenshot includes the entire response, including Interface State, Signal Quality, and APN Settings.
  3. Save the captured screenshot and send it to the Neeve Support team for investigation.
