Grandstream GWN7816 Layer 3 Managed Switch, 48 GbE + 6 x 10G SFP+

Overview

The Grandstream GWN7816 is a 48-port Gigabit network switch for large offices, campuses and hotels, where many wired devices connect on one floor or in one building and downtime is costly. It routes traffic between network segments itself (Layer 3, with OSPF and BGP), links to the core over six 10 Gbps SFP+ ports, and takes a second hot-swap power supply so a failed supply does not take the network down. It has no Power over Ethernet (PoE): the GWN7816P is the PoE version.

Is it right for you?

• Suits a high-density access or aggregation role in large offices, campuses and hotels where uptime matters.
• Choose it when you need dynamic routing (RIP, OSPF, BGP) between many networks at the switch, not just static routes.
• It does not power devices: if your phones, cameras or access points need PoE, choose the GWN7816P.
• Up to four switches can be stacked and managed as one, which suits sites that will grow.
• For a smaller network with fewer wired devices, a smaller switch is enough.

Key features

• 48 Gigabit RJ45 ports plus 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 70 W hot-swap power supply is fitted and a second slot takes a backup supply, so the switch keeps running if one fails.
• 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 are in the kit. Allow front to back airflow for the four fans and keep the room between 0 and 45 °C. The unit measures 440 x 300 x 44 mm and weighs 4.7 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

• No PoE on this model; the GWN7816P is the PoE version.
• 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.
