Grandstream GWN7822P Layer 3 Multi-Gig PoE++ Switch, 24 Ports, 4 x SFP+, 360 W

Overview

The Grandstream GWN7822P is a 24-port network switch for growing business networks that mix ordinary wired devices with faster Wi-Fi access points. Sixteen Gigabit ports and eight 2.5 Gbps ports all supply Power over Ethernet (PoE), with up to 60 W on the 2.5 Gbps ports for multi-Gigabit access points, four 10 Gbps SFP+ ports link it to the core, and it routes between network segments itself (Layer 3).

Is it right for you?

• Suits an office or floor with phones, cameras and a few multi-Gigabit access points on one switch.
• The 360 W PoE budget is shared, so six devices at 60 W would use all of it; add up the expected load before choosing.
• Only ports 17 to 24 (the 2.5 Gbps ports) supply up to 60 W; ports 1 to 16 supply up to 30 W.
• Choose it when you want routing between VLANs (virtual LANs) at the switch, with RIP, OSPF and BGP available.
• If you only need the eight 2.5 Gbps ports, the GWN7821P is the smaller model.

Key features

• 16 Gigabit ports (up to 30 W PoE each) plus eight 2.5 Gbps ports (up to 60 W PoE each, IEEE 802.3af/at/bt), 360 W in total.
• Four 10 Gbps SFP+ uplinks, 152 Gbps switching capacity and 113.088 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; 512 IPv4 and 128 IPv6 routes.
• Stacking of up to four switches as one logical device.
• 4K VLANs, private VLAN, voice VLAN, 32 link aggregation groups and 2K ACLs (access control lists).
• Built-in 420 W power supply (54 V, 7.78 A) with the AC cable included, plus an input for an optional external 54 V (300 W) redundant power supply (RPS).
• The SFP+ ports accept direct attach copper (DAC) cables up to 5 m as well as fibre modules.

What else you need

• A mains socket: the power supply is built in and the AC cable is included.
• Cat5e or better cabling to the 2.5 Gbps devices.
• 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.
• Only if you want backup power: an external 54 V (300 W) RPS.
• 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 on a desk or in a 19 inch rack; the rack kit is included. Connect the supplied ground cable, allow airflow for the two fans and keep the room between 0 and 45 °C. Plan the PoE allocation so high-power devices land on ports 17 to 24. The unit measures 440 x 300 x 44 mm and weighs 4.1 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 360 W budget is shared: six devices at 60 W use all of it.
• Check that cabling to 2.5 Gbps devices is Cat5e or better.
• SFP+ modules are not included.
• Backup power needs the optional external 54 V (300 W) RPS.
• Rated for 0 to 45 °C.
