Grandstream GWN7721 Lite Managed 2.5G Switch, 8 x 2.5GbE, 2 x 10G SFP+

Overview

The Grandstream GWN7721 is a managed network switch (Layer 2 Lite) with eight 2.5 Gbps ports and two SFP+ (enhanced Small Form-factor Pluggable) uplinks at up to 10 Gbps. It gives each Wi-Fi 6 or Wi-Fi 7 access point more than 1 Gbps and a 10 Gbps path to the router or core switch. It suits small and medium offices, hotels and apartment buildings moving to faster Wi-Fi.

Is it right for you?

• Choose it when your access points or workstations support 2.5 Gbps and you want VLANs (virtual LANs) and monitoring. The unmanaged GWN7701M has the same eight 2.5 Gbps ports with one SFP+ and nothing to configure.
• It has no PoE, so access points need their own power or a PoE injector. The GWN7721P and GWN7721PE add PoE.
• Two SFP+ slots give a 10 Gbps uplink plus a spare for a second link or another switch.
• Desk or wall mounting in a metal case with a Kensington lock slot.

Key features

• Eight RJ45 ports at 100 Mbps, 1 Gbps or 2.5 Gbps for Wi-Fi 6 and Wi-Fi 7 access points or fast workstations.
• Two SFP+ slots that run at 1, 2.5 or 10 Gbps.
• 80 Gbps switching capacity, 40 Gbps non-blocking throughput, 16K MAC addresses and jumbo frames up to 9216 bytes.
• Up to 32 VLANs (port-based and 802.1Q), QoS (Quality of Service) with 802.1p and DSCP mapping, IGMP snooping, STP/RSTP, DHCP snooping and loop detection.
• Link aggregation of up to 5 groups with 8 members each.
• Cable test, port mirroring, fibre module diagnostics and SNMP for fault finding.
• Metal housing, 190 x 100 x 28 mm and 0.6 kg, with a Kensington lock slot.
• Powered by an external 12 V DC 1 A adapter, which is included.

What else you need

• Power: the external 12 V adapter is included.
• For the uplinks, SFP+ modules or DAC (direct attach copper) cables, which are not supplied. Grandstream F-MM850-300M-10G (multimode) and F-SM1310-10KM-10G (single-mode) 10 Gbps modules fit the slots; F-MM850-550M-1.25G and F-SM1310-20KM-1.25G match the 1 Gbps mode; 1 m and 3 m DAC cables are listed for this series.
• A power adapter or PoE injector for each access point or other powered device.
• Cat5e or better cabling and 2.5 Gbps devices to get the full port speed.

Installation

Placing it is simple: desk or wall, plug in the adapter and connect the cables, within 0 to 45 °C. An IT or network installer then sets VLANs, QoS and the uplinks through the web interface or GDMS Networking.

Software and licences

• Managed through its local web interface, GDMS (Grandstream Device Management System) Networking in the cloud, GWN Manager on your own server, or the GWN App, with SNMP v1/v2c for third-party monitoring.
• No licence is listed.

Before you buy

• No PoE: the GWN7721P and GWN7721PE add it.
• No SFP+ modules or DAC cables are supplied.
