Grandstream GWN7721P Lite Managed 2.5G PoE+ Switch, 8 Ports, 2 x SFP+, 130 W

Overview

The Grandstream GWN7721P is a managed network switch (Layer 2 Lite) with eight 2.5 Gbps ports that all supply Power over Ethernet (PoE/PoE+), plus two SFP+ (enhanced Small Form-factor Pluggable) uplinks at up to 10 Gbps. It powers Wi-Fi 6 and Wi-Fi 7 access points and gives each one more than 1 Gbps, with 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 cameras support 2.5 Gbps and take power over the cable. The GWN7721 is the same switch without PoE.
• The 130 W budget covers four devices at the full 30 W, or more lower-power devices. Add up the draw of every powered device first.
• If one device needs more than 30 W on a 10 Gbps copper link, the GWN7721PE adds a PoE++ port.
• Desk, wall or rack mounting, with the rack kits included, so it suits a comms cabinet as well as a shelf.

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.
• PoE/PoE+ (802.3af/at) on all eight copper ports, 30 W per port and 130 W in total, with a PoE watchdog that restarts a device that stops responding.
• 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, 280 x 180 x 44 mm and 1.58 kg, with a built-in 100 to 240 V AC power supply.

What else you need

• Power: a mains socket. The power supply is built in.
• 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.
• Cat5e or better cabling and 2.5 Gbps devices to get the full port speed.

Installation

An IT or network installer should fit it. It stands on a desk, mounts on a wall or goes in a rack with the extended rack kits in the box, within 0 to 45 °C. Connect the supplied ground cable, plug in the mains lead and the device cables, then set VLANs, QoS, PoE 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

• 130 W is shared across the eight PoE ports.
• No SFP+ modules or DAC cables are supplied.
• Connect the supplied ground cable.
