Grandstream GWN7721PE Lite Managed PoE++ Switch, 8 x 2.5G, 1 x 10G, 1 x SFP+

Overview

The Grandstream GWN7721PE is a managed network switch (Layer 2 Lite) with eight 2.5 Gbps Power over Ethernet (PoE/PoE+) ports, one 10 Gbps copper port that supplies up to 90 W (PoE++), and one SFP+ (enhanced Small Form-factor Pluggable) 10 Gbps uplink. It powers Wi-Fi 6 and Wi-Fi 7 access points plus one high-power device, 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 one high-power device, such as an access point drawing more than 30 W, must sit on a 10 Gbps copper link. If no device needs more than 30 W, the GWN7721P has two SFP+ uplinks instead.
• The 130 W budget is shared by all nine PoE ports, so add up the draw of every powered device, including the 90 W port.
• There is only one SFP+ slot, so fibre gives one uplink; the 10 GbE copper port can be the second.
• Desk or rack mounting with the rack kits included.

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.
• One 10 GbE RJ45 port and one 10 Gbps SFP+ slot for uplinks.
• PoE on all nine copper ports: 30 W (802.3af/at) on ports 1 to 8 and up to 90 W (802.3bt PoE++) on the 10 GbE port, 130 W in total.
• 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 1.848 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 SFP+ uplink, a transceiver or DAC (direct attach copper) cable, which is not supplied. Grandstream F-MM850-300M-10G (multimode) and F-SM1310-10KM-10G (single-mode) 10 Gbps modules fit the slot, and 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 or goes in a rack with the extended rack kits in the box, within 0 to 45 °C. Connect the supplied ground cable, fit the power cable clamp, 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
