Introduction
The GWN7721 Series is a family of Layer 2 Lite managed multi-gigabit switches designed for small-to-medium businesses, hotels, home offices, and other high-speed network deployments. The series combines scalable wired connectivity, optional PoE for powering devices such as IP phones, cameras, and Wi-Fi access points, and flexible management through the local web interface, GWN Manager, GDMS Networking, and the GWN App.

Precautions
- Do not open, disassemble, or modify the device.
- Operate the device at 0–45 °C and store it at -20–60 °C.
- Keep the device in an environment with 10–90% relative humidity (non-condensing).
- Use supported Ethernet connections: 10/100/1000/2500 Mbps, the 10 Gbps RJ45 port on GWN7721PE, and SFP+.
- For PoE output, GWN7721P supports up to 30 W per PoE port. On GWN7721PE, ports 1–8 support up to 30 W each and port 9 supports up to 90 W.
- Keep the grounding wire securely connected while the device is in use.
Package Content
Rack Mounting (GWN7721P/GWN7721PE)
- Attach the four rubber feet to the marked locations on the bottom of the switch for desktop installation.
- For rack installation, align the supplied rack-mount brackets with the screw holes on both sides of the switch.
- Secure the brackets to the switch with the supplied KM 3 × 6 mm screws.
- Place the switch in the rack and secure both brackets to the rack.
Power and Grounding
- Connect the supplied 12 V power adapter to the GWN7721, or connect the supplied AC power cord to the GWN7721P/GWN7721PE.
- Connect one end of the grounding cable to the grounding point on the switch.
- Connect the other end to a suitable grounding point and verify that the connection is secure before powering on the switch.
Network Setup
- Connect a router, gateway, computer, access point, IP phone, or other network device to an Ethernet port on the switch.
- Use the 10G SFP+ port or ports for a compatible fiber or high-speed uplink when required.
- For GWN7721P, connect PoE devices to ports 1–8. Each port supports up to 30 W.
- For GWN7721PE, connect PoE/PoE+ devices to ports 1–8 (up to 30 W per port). Use port 9 for a 10G PoE/PoE+/PoE++ device requiring up to 90 W.
- Confirm that all cables are securely connected and that the required port LEDs are active.
