Grandstream GWN7816P 48‑Port Layer 3 Managed PoE Switch | 6x 10G SFP+ & Stackable

Grandstream GWN7816P: Enterprise‑Grade Layer 3 PoE++ Switch for Scalable Networks

The Grandstream GWN7816P is the flagship managed switch in the GWN7800 series, engineered to provide medium‑to‑large enterprises with a resilient, high‑performance, and future‑proof network core. It combines robust Layer 3 routing capabilities with an immense PoE budget and 10G uplinks, all managed through a simple, licence‑free ecosystem.

High‑Performance Switching & Routing

The GWN7816P features 48 Gigabit Ethernet ports and 6 x 10 Gigabit SFP+ ports, delivering a non‑blocking switching capacity of 216 Gbps and a forwarding rate of 160.704 Mpps. This ensures wire‑speed performance even when all ports are fully utilised. The 10G SFP+ ports can be used for high‑speed fibre uplinks to a core switch or for stacking multiple switches into a single logical unit with redundant links.

Enterprise‑Grade PoE++ Power

All 48 Gigabit ports support Power over Ethernet, with a total budget of 740W:

• 8 ports support PoE++ (802.3bt) delivering up to 60W per port – ideal for high‑power devices such as PTZ cameras, digital signage, or video conferencing hubs.

• 40 ports provide PoE+ (802.3at) with up to 30W per port – perfect for IP phones, Wi‑Fi 6/7 access points, and fixed IP cameras.

This smart dynamic PoE control automatically allocates power per port, optimising energy usage and simplifying installations by eliminating the need for external power injectors.

Advanced Layer 3 Routing & Stacking

Unlike basic Layer 2+ switches, the GWN7816P can route traffic between VLANs directly on the switch, reducing latency and eliminating the need for a separate router. It supports:

• Static routing (32 IPv4 / 32 IPv6 routes)

• Dynamic routing protocols – RIP, RIPng, OSPF, OSPFv3, and BGP for complex, multi‑site routing

• Policy‑based routing (pending) and VRRP (pending) for high‑availability network cores

• A large routing table with 12,000 IPv4 routes and 4,000 IPv6 routes

• Stacking support (coming soon) to manage up to 16 switches from a single interface, simplifying administration and creating redundant backup links

Enterprise‑Grade Security & Reliability

The GWN7816P includes a comprehensive security suite to protect your network:

• Port‑based authentication with 802.1X and MAC authentication, backed by RADIUS/TACACS+ AAA

• DHCP Snooping & Dynamic ARP Inspection (DAI) – blocks man‑in‑the‑middle and spoofing attacks

• IP Source Guard – filters unauthorised IP traffic on untrusted ports

• DoS attack prevention, storm control, port isolation, sticky MAC filtering

• Loop protection – BPDU Guard, Root Guard, and loopback protection

• Secure management via HTTPS, SSH, SNMPv3, and user hierarchical privilege management

• Hardware reliability – dual firmware images, dual system file redundancy, and a hot‑swap PSU (second unit sold separately) for 1+1 redundancy

Free & Flexible Management

The GWN7816P can be managed through multiple interfaces at no extra cost:

• Local web UI and CLI – for granular, on‑device control

• GDMS Networking – free cloud platform for zero‑touch provisioning, real‑time monitoring, and bulk upgrades across thousands of switches, routers, and APs

• GWN Manager – on‑premise software controller for enterprises that prefer local management

All options are completely licence‑free, keeping your total cost of ownership low.

Why Choose the GWN7816P?

• Unmatched PoE capacity – 740W budget with 60W per port on 8 ports, powering even the most demanding devices

• 10G fibre readiness – 6 SFP+ ports for high‑speed uplinks or stacking

• True Layer 3 routing – dynamic routing (RIP, OSPF, BGP) for inter‑VLAN traffic without a separate router

• Stackable design – scale your network without management complexity

• Free, centralised management – GDMS cloud or GWN Manager, no licences

• Enterprise‑grade security & reliability – hot‑swap PSU, DAI, IP Source Guard, and more.
