Key Features & Benefits

High-density PoE+ for demanding deployments
This model is equipped with 48 PoE+ ports and is ideal to power APs, IP cameras, VoIP, IoT devices, and more — all in one chassis.

10G uplinks give high-bandwidth backhaul
The 4 SFP+ 10G uplink ports provide abundant bandwidth to consolidate traffic to the network core or servers, avoiding bottlenecks.

Advanced Layer 2 / Layer 3 features
Supports static routing, policy-based routing, IPv6 forwarding, and enterprise switching features fully — so you can segment, route, and manage traffic inside the network.

Powerful VLAN & segmentation feature
With the ability to support thousands of VLANs, private VLANs, Q-in-Q, selective Q-in-Q, protocol-based VLANs, you can segment traffic intelligently (e.g. for guests, employees, IoT).

Scalable stacking & intuitive management
Stack up to 4 switches and treat them as a single unit — simplifies configuration, monitoring, and failover.

Redundancy & protection features
Improves support for STP versions, UDLD, loop detection, link aggregation, link protection and failover to guard against topology defects.

Multicast and IPTV support
IGMP snooping, querier, and proxy support efficiently control multicast traffic and IPTV in campus or branch networks.

Dual firmware / upgrade security
Dual images allow you to experiment with new firmware and roll back in the event of a requirement with low downtime risk.

Secure and enterprise-class management
RADIUS/TACACS+ support, secure SSH/SSL management, role-based access control, and ACLs provide hardened network edge.

Effective energy and noise design
With effective hardware and thermal design; ideal for wiring closet or network room installation without excessive noise.

Use Cases & Deployment Scenarios

Campus / branch core access layer
Preferred for connecting end devices (APs, cameras, desktops) and aggregating to core routers or switches.

Wireless infrastructure aggregation
Power scores of Wi-Fi 6 / Wi-Fi 6E / Wi-Fi 7 access points with headroom in the uplink.

Surveillance / security systems
Power IP camera fleets, analytics nodes, and security sensors across the site.

Converged networks (voice, video, data, IoT)
Handle mixed traffic types, segregate with VLANs, and prioritize QoS-sensitive apps.

Edge routing & segmentation
Employ its Layer 3 feature for routing between VLN, PBR, or routing at remote locations, offloading load from higher-end routers.
