"Soft Reset" or "Deactivation" = The Edge is deactivated, which means that the existing configuration the Edge is using is completely removed and the Edge now uses the original factory configuration. However, the Edge software is not affected and retains the build it had prior to the soft reset. A soft reset Edge can be reactivated to another site or to the same site.
"Hard Reset" = The Edge is fully reset to factory settings. Not only is the Edge deactivated and uses the factory configuration, but the Edge software is also changed to the factory software build. This Edge is effectively as it was when it was shipped from the factory.
An Edge can be soft reset/deactivated using the Orchestrator. This allows an enterprise administrator to perform the task in a simple and quick fashion without needing either themselves or someone else be local to the Edge.
Once the Deactivate command is confirmed, the Orchestrator will send the signal to deactivate the Edge and clear the configuration. The administrator will lose contact with the Edge through the Orchestrator and the Edge and the Orchestrator would show the Edge as offline. Someone local would observe the Edge reboot as it completes the deactivation.
A user may perform either a soft reset/deactivation or a hard reset of the Edge using the Edge's local web user interface.
The first step is to confirm that a local PC can access the Edge through a LAN port. Beginning with Release 3.2.1 and later, access to the Edge through a LAN port is blocked by default.
Configuring LAN side Edge access is done on the Orchestrator:
1. Got to Configure->Edge->Firewall and scroll down to change the Edge Access Firewall setting.
2. Check Enable Edge Override if it is not already selected.
3. Under Local Web UI Access select Allow the Following IPs and specify the IP address of the client device that will access the Edge, and Save Changes.
Note: While it may be simpler to select Allow All LAN for this section, the user should remember to deselect this option once the reset is done as a matter of best security practices.
With LAN side Edge access confirmed the steps are as follows:
1. Connect the Client PC to the Edge (either via Wi-Fi or Ethernet cable).
2. Open a web browser and enter edge.velocloud.net (or the LAN IP address) into the address bar.
3. Beginning with Edge release 3.2.1, the user will be asked for local authentication credentials to continue.
Note: Edge local credentials may be found on the Orchestrator by going to Configure->Edge->Edge Overview and selecting the View option next to Local Credentials.
If the Edge is not connected to the Orchestrator, and the Local UI is not accessible, there is a final option to reset an Edge. For this method the user manually hard resets the Edge as described below using the reset button on the back of the Edge:
If the Edge is not connected to the Orchestrator, and the Local UI is not accessible, there is a final option to reset these listed Edge models. For this method, the Edge is hard reset by accessing the boot GRUB menu through a USB keyboard and a VGA monitor:
Note: this method can only hard reset the Edge, there is no method to manually soft reset/deactivate an Edge through the GRUB menu.
Hard resetting an Edge 3400 or 3800 differs from the older rack-mounted model 840, 1000/2000. For this model line, you will need to connect a PC to a RS232 console port. This difference means that a required piece of equipment to perform this reset is a USB-to-Serial cable. The USB connector is for the laptop.
For the 3800's, you can use a USB to RJ-45 cable.
Note: if the user does have a laptop with a 9 pin DB9 serial connector then only a standard serial cable would be needed, but laptops so equipped are rare and thus our recommendation for the USB-to-Serial cable.
With a laptop, connect the RJ45 end into the circled port on the left front of the Edge 3X00.
The laptop can use PuTTY or any other serial terminal emulator program. The default terminal settings on the console are as follows:
The steps to reset the Edge are the same as for the 840/1000/2000/3x000 model:
Note: this method can only hard reset the Edge, there is no method to manually soft reset/deactivate an Edge through the GRUB menu.
Impact/Risks:
If a VMware SD-WAN Edge is reset, the Edge is cleared at a minimum of the existing configuration and activation (soft reset). On a hard reset the Edge also reverts back to its original factory software image.
If the Edge is being actively used at a customer site, performing a reset will result in the complete loss of client device connectivity at the site until the Edge is reactivated to the site or another Edge is activated in its place.
