Replacing a SonicWall Security Appliance

If your SonicWall security appliance has a hardware failure while still under warranty, SonicWall will replace it. In this case, you need to remove the HA association containing the failed appliance in MySonicWall, and add a new HA association that includes the replacement. If you contact SonicWall Technical Support to arrange the replacement (known as an RMA), Support will often take care of this for you.

After replacing the failed appliance in your equipment rack with the new unit, you can update MySonicWall and your SonicOS configuration.

Replacing a failed HA Primary unit is slightly different than replacing an HA Secondary unit. Both procedures are provided in these sections:

Replacing an HA Primary Unit
To replace an HA Primary unit:
1
In the SonicOS management interface of the remaining SonicWall security appliance (the Secondary unit), on the High Availability screen, uncheck Enable High Availability to disable it.
2
Check Enable High Availability.

The old Secondary unit now becomes the Primary unit. Its serial number is automatically displayed in the Primary SonicWall Serial Number field.

3
Type the serial number for the replacement unit into the Secondary SonicWall Serial Number field.
4
Click Synchronize Settings.
5
On MySonicWall, remove the old HA association. See Removing an HA Association.
6
On MySonicWall, register the replacement SonicWall security appliance and create an HA association with the new Primary (original Secondary) unit as the HA Primary, and the replacement unit as the HA Secondary. See Registering and Associating Appliances on MySonicWall.
7
Contact SonicWall Technical Support to transfer the security services licenses from the former HA Pair to the new HA Pair.

This step is required when the HA Primary unit has failed, because the licenses are linked to the Primary unit in an HA Pair.

Replacing an HA Secondary Unit
To replace an HA Secondary unit:
1
On MySonicWall, remove the old HA association. See Removing an HA Association.
2
On MySonicWall, register the replacement SonicWall security appliance .
3
Create an HA association with the original HA Primary, using the replacement unit as the HA Secondary. See Replacing an HA Primary Unit.
