FAQs

Q: Can this HA unit manage APs by itself?
A: No. The HA SKU includes zero AP licenses and is intended only as a standby for failover.

Q: How is it paired for redundancy?
A: Deploy it in an N+1 topology with a licensed 2504; upon failover it assumes control per the active controller’s configuration and licensing model.

Q: Do I need additional licenses for the HA controller?
A: The HA SKU itself carries no AP licenses; licensing resides on the active licensed controller in the redundancy design.

Q: Does it support LAG and the same features as the primary?
A: Yes. Hardware capabilities match the 2504 platform, including LAG, VLANs, and mobility features.
