When a new W-IAP is added into an existing cluster, it can join the cluster only if the existing cluster is running at least the minimum required version of that AP. If the existing cluster is running a version below the minimum required version of the new AP, new AP will not come up and may reboot with the reason Image sync fail. To recover from this condition, upgrade the existing cluster to at least the minimum required version of the new AP first, and add the new AP. Dell recommends that networks with more than 128 APs be designed as multiple, smaller virtual-controller networks with Layer-3 mobility enabled between these networks. The following table provides the variants supported for each W-IAP platform: Table 4: Supported W-IAP Variants W-IAP Model (Reg Domain) W-IAP###US (US only) W-IAP###-JP (Japan only) W-IAP###-RW (Worldwide except US) W-IAP### (Worldwide except US and Japan) W-IAP277 Yes No Yes No W-IAP228 Yes No Yes No W-IAP205H Yes No Yes No W-IAP204/205 Yes No Yes No W-IAP214/215 Yes No Yes No 30 | About Instant Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide
