Description
Businesses today need more than standard Gigabit speeds. The Grandstream GWN7721 gives you exactly that with eight 2.5G Ethernet ports and two blazing-fast 10G SFP+ ports. This Layer 2 Lite managed switch helps small-to-medium businesses, hotels, and offices build reliable, high-performance networks without complexity.
The Telecom Spot Take
For customers of all sizes, the GWN7721 strikes a perfect balance. It future-proofs your network for bandwidth-hungry applications like video conferencing, large file transfers, and cloud services while keeping things simple and affordable. Its fanless operation means it runs silently in any office environment, and flexible management options (local web, GWN Manager, or cloud GDMS) fit any deployment style. Perfect if you need multi-gig speeds but don’t require PoE from the switch itself.
Key Features
- 8x 2.5 Gigabit Ethernet ports – Connect laptops, desktops, and IP devices at 2.5x the speed of traditional Gigabit for smoother video, faster transfers, and future-ready performance
- 2x 10 Gigabit SFP+ uplink ports – Link to core switches, servers, or storage with blazing 10G speeds so your entire network stays fast end-to-end
- Fanless metal design – Runs completely silent and reliable in noise-sensitive spaces like offices, hotels, and conference rooms
- Layer 2 Lite management with flexible options – Choose local web UI, on-premise GWN Manager, or cloud-based GDMS Networking—free and simple for any IT setup
- Built-in QoS and traffic prioritization – Automatically gives voice, video, and critical data the bandwidth they need for crystal-clear calls and lag-free streaming
- VLAN segmentation and IGMP Snooping – Keep departments or guest networks secure and isolated while optimizing multicast traffic like IPTV
- Advanced security & troubleshooting tools – DHCP Snooping, STP/RSTP, Loop Detection, Cable Test, Port Mirroring, and SNMPv2 help you prevent issues and fix them fast
- Compact desktop/wall-mount – Easy to install anywhere with a small footprint (190 x 100 x 28 mm) and rugged metal enclosure

Comparison at a Glance
- vs Typical Gigabit unmanaged switches: The GWN7721 adds managed Layer 2 features (VLANs, QoS, security) plus 2.5G speeds and 10G uplinks—without the noise or complexity of full Layer 3 models.
- vs GWN7721P (PoE version): Same high-speed ports and management, but the GWN7721 is non-PoE, lighter, more compact, and uses less power—ideal when your devices already have their own power or you’re focused purely on data throughput.
- vs older 1G managed switches: 2.5x faster Ethernet ports and 10G uplinks handle today’s bandwidth demands while keeping the same easy management Grandstream customers already trust.
Frequently Asked Questions
What makes the GWN7721 different from a standard Gigabit switch?
It delivers 2.5 Gigabit speeds on all eight Ethernet ports plus two 10G SFP+ uplinks, plus full Layer 2 management features like VLANs and QoS—giving your business noticeably faster and more reliable performance.
Does the GWN7721 support PoE?
No—this is the non-PoE model. If you need power over Ethernet for IP phones, cameras, or access points, consider the GWN7721P instead.
How do I manage the switch?
Choose what works for you: simple local web interface, free on-premise GWN Manager software, or the cloud-based GDMS Networking platform. All options are included at no extra cost.
Is it quiet enough for an office environment?
Yes—completely fanless design means zero noise, even under full load. Perfect for desks, conference rooms, or any quiet workspace.
What mounting options does it support?
Desktop or wall-mount—compact size (190 x 100 x 28 mm) makes installation easy in any location.
Does it include advanced security features?
Yes—DHCP Snooping prevents rogue DHCP servers, STP/RSTP avoids network loops, and built-in tools like Loop Detection and Cable Test make troubleshooting fast and simple.
