Grandstream GWN7816P Layer 3 Managed PoE++ Switch, 48 GbE + 6 x 10G SFP+, 740 W

Overview

The Grandstream GWN7816P is a 48-port Gigabit network switch that connects and powers phones, cameras and Wi-Fi access points in large offices, campuses and hotels where downtime is costly. Every copper port supplies Power over Ethernet (PoE), with up to 60 W on ports 1 to 8 for high-power devices, and six 10 Gbps SFP+ ports link it to the core over fibre. It routes between network segments itself (Layer 3, with OSPF and BGP) and takes a second hot-swap power supply.

Is it right for you?

• Suits a high-density access or aggregation role where many phones, cameras and access points need power from the switch and uptime matters.
• The 740 W PoE budget is shared across all 48 ports with the single factory power supply; add up the expected load before choosing.
• Only ports 1 to 8 supply up to 60 W (PoE++); connect high-power devices to those ports.
• Choose it when you need dynamic routing (RIP, OSPF, BGP) at the switch. If you do not need PoE, the GWN7816 is the same switch without it.
• Up to four switches can be stacked and managed as one, which suits sites that will grow.

Key features

• PoE on all 48 Gigabit ports: up to 60 W (IEEE 802.3af/at/bt) on ports 1 to 8, up to 30 W on ports 9 to 48, 740 W in total with one PSU.
• Six 10 Gbps SFP+ uplinks, 216 Gbps switching capacity and 160.704 Mpps forwarding rate.
• Layer 3 routing: static routes plus RIP (Routing Information Protocol), OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol), with RIPng and OSPFv3 for IPv6; 12K IPv4 and 4K IPv6 routes.
• Modular power: one 920 W hot-swap power supply is fitted and a second slot takes a backup supply.
• Stacking of up to four switches as one logical device.
• 4K VLANs, private VLAN, QinQ and 4K ACLs (access control lists) for separating and filtering traffic.
• 802.1X, RADIUS and TACACS+ authentication to keep unauthorised devices off the network.
• The SFP+ ports accept direct attach copper (DAC) cables up to 5 m as well as fibre modules; four fans with front to back airflow.

What else you need

• A mains socket for the fitted power supply.
• For power redundancy, a second hot-swap PSU module, bought separately.
• SFP+ modules for the 10 Gbps uplinks: these are not included. Grandstream’s F-MM850-300M-10G (multimode fibre, up to 300 m) and F-SM1310-10KM-10G (single-mode fibre, up to 10 km) match the port speed. Up to three RJ45 10G modules are supported.
• No extra software is needed for local management: the web UI and command-line interface (CLI, over console, Telnet or SSH) are built in. For central management use GDMS Networking (cloud), GWN Manager (on-premises) or a GWN series router.

Installation

A network installer or IT team should fit and configure it. It mounts in a 19 inch rack or on a desk; front and rear rack-mounting brackets and rear slideways are in the kit. Allow front to back airflow for the four fans and keep the room between 0 and 45 °C. Plan the PoE allocation so high-power devices land on ports 1 to 8. The unit measures 440 x 380 x 44 mm and weighs 6 kg.

Software and licences

Management is through the local web UI, the CLI, SNMP v1/v2c/v3, GDMS Networking in the cloud, GWN Manager on your own server or a GWN series router. Local management works without an internet connection; GDMS Networking needs one.

Before you buy

• The 740 W PoE budget applies with the single factory PSU.
• Only one power supply is fitted. Buy the matching hot-swap PSU module separately if you want redundancy.
• SFP+ modules are not included.
• Rated for 0 to 45 °C; place it in a ventilated equipment room or cabinet.
