Managing network devices remotely is essential for maintaining uptime and reducing operational costs. However, what happens when you lose IP connectivity to a device behind your router? Traditionally, you would need to travel to the site and connect via the console port—a time-consuming and costly process. Fortunately, the InHand ER805 router offers an Out-of-Band Management (OOBM) feature that solves this problem. 

What is Out-of-Band Access? 

Out-of-Band (OOB) access is a management mechanism that uses a dedicated connection separate from the production network. This ensures that even if the primary network fails, you can still manage and troubleshoot devices remotely. 

The ER805 router supports dual connectivity: 

  • Primary Internet Line 

  • 5G SIM Card for Cellular Backup 

This redundancy ensures continuous Internet access for management purposes. 

Scenario 

Imagine you lose IP connectivity to a device behind the ER805 router. Instead of traveling onsite, you can use the ER805’s OOB feature to access the device’s console remotely via InCloud Manager. 

How It Works 

By connecting your device’s console port to the ER805’s serial/USB port, you create a pathway for remote console access. The ER805 acts as a bridge between your remote terminal and the device’s console. Refer to the picture below.  

Step-by-Step Guide to Remote Console Access 

  1. Login to InCloud Manager 

  1. Use your credentials to access the cloud management platform. 

  1. Open the ER805 Device 

  1. From the list of devices you have, select the ER805 of your concern. 

  1. Go to the Clients Tab 

  1. This tab exposes the OOBM button 

  1. Click on the OOBM Button 

  1. This opens the Out-of-Band Management configuration window. 

  1. Configure Tunnel Settings 

  1. In the pop-up window:  

  1. Select Tunnel Protocol: COM or TCP 

  1. Fill in the details according to your device’s specifications. 

  1. Example for a Cisco device:  

  1. Baud Rate: 9600 

  1. Data Bits: 8 

  1. Stop Bits: 1 

  1. Parity: None 

  1. Create the Tunnel 

  1. Click Create Tunnel to establish the connection. 

  1. Access the Device 

  1. Use the provided address and port to connect via Telnet or SSH from your preferred terminal. 

  1. Example using PuTTY:  

  1. Enter the IP and port.
