Description

A 5508 Series High-Availability controller (HA-SKU) designed to serve as a license-free standby unit for stateful switchover (SSO) or N+1 redundancy. This unit does not include AP licenses and is not intended to operate standalone with joined APs; it activates during failover to maintain client sessions and minimize downtime. Provides eight 1G data ports, a dedicated service port, a redundancy port, and supports 802.3ad LAG. Ideal for enterprises standardizing on SSO for nonstop WLAN services.

Features

- Nonstop WLAN: Enables SSO for minimal disruption during failover
- License-free standby: HA-SKU dedicated to redundancy roles
- Robust connectivity: 8x 1G data ports with LAG
- Enterprise features retained after switchover: QoS, RRM, AVC, and security
- Simplified resilience: Streamlined deployment for N+1 or SSO topologies
