SonicWave 200 Series Subscriptions and Renewals
The 'Secure Wireless Network Management and Support' covers your 200 Series (231c, 224w & 231o) SonicWall access point for extended warranty (replacement in case of hardware failure) & technical support; as well as the optional cloud management (WNM).
This is the same renewal even if your SonicWave is managed by the firewall. The WNM is optional and you can easily move from firewall-managed to cloud-managed.
