Grandstream GWN7816P 48-Port Layer 3 PoE Switch with 740W Budget

The Grandstream GWN7816P is a Layer 3 managed switch with 48 Gigabit PoE ports, a 740W budget and six 10G SFP+ slots, powered by a 920W supply with a bay for a second hot-swap unit. It is meant for core network rooms in hospitals, malls and large hotels.

====

The Grandstream GWN7816P is the largest model in the GWN781x Layer 3 family: 48 Gigabit PoE ports, six 10G SFP+ slots and a 740W PoE budget. It is built for the main network room of a large building, where hundreds of cameras, access points and phones meet, and where a failed power supply cannot be allowed to take the whole site offline.

Grandstream GWN7816P capacity and key numbers

Key numbers:

• 48 Gigabit RJ45 ports, IEEE 802.3af/at/bt.
• Ports 1 to 8 up to 60W (PoE++); ports 9 to 48 up to 30W.
• 6 × 10G SFP+ slots.
• 216Gbps switching capacity, 160.704Mpps forwarding rate.
• 32K MAC table, 12K IPv4 and 4K IPv6 routes.

740W of PoE for a full deployment

Port count tells you how many devices you can plug in; the budget tells you how many you can actually power. With 740W you can run 24 access points drawing a full 30W each and still have headroom, or spread the power across cameras and phones that draw far less. The first eight 60W ports handle PTZ cameras and other devices that go beyond PoE+.

Hot-swappable power supply

The switch ships with a 920W power supply and has a second bay for a CRPS-920W unit, sold separately, that can be inserted or removed while the switch is running. With both fitted you get 1+1 redundancy and load sharing. In a hospital wing or a CCTV control room, one failed supply no longer means a dark floor.

Layer 3 routing with larger tables

Create up to 32 VLAN interfaces and let the switch route between them using static routes, RIP, OSPF or BGP. Access control is handled by 4K ACL entries, 802.1X, ARP inspection, DHCP snooping and DoS prevention. Manage it locally through the web UI and CLI, or centrally through GDMS Networking or GWN Manager. 64 spanning tree instances and 2K ARP entries round out a feature set sized for big networks.

Installation and cooling

The switch is one rack unit high (44 mm), 380 mm deep and weighs 6 kg. Front and rear rack kits with rear slideways are in the box, so check your rack depth before ordering. Four fans keep it within its 0°C to 45°C operating range, which matters in network rooms where the air conditioning struggles in summer.

Typical GWN7816P projects in Saudi Arabia

• Hospitals and medical complexes: cameras, access points and nurse-station phones on one switch per wing.
• Malls and office towers: a core switch feeding floor switches over six 10G fiber links.
• Large hotels in Makkah and Madinah: Wi-Fi for hundreds of rooms plus a separate network for hotel systems.
• Universities and campuses: isolated networks for staff, students and surveillance.

GWN7816P or GWN7813P?

The GWN7816P has twice the ports of the GWN7813P (48 vs 24), 6 SFP+ slots instead of 4, a 740W budget instead of 370W and much larger routing tables (12K IPv4 routes vs 512), and a 32K MAC table instead of 16K. Both limit 60W to ports 1 to 8. It also uses a second internal hot-swap supply rather than an external RPS. If your site needs 24 ports or fewer, the GWN7813P does the job in half the space.

Frequently Asked Questions

What is the PoE budget of the GWN7816P?

740W with one power supply. Ports 1 to 8 deliver up to 60W each and ports 9 to 48 up to 30W.

Can I add a second power supply?

Yes. It ships with a 920W PSU and has a bay for a second CRPS-920W, sold separately and hot-swappable, giving 1+1 redundancy with load sharing.

How does it differ from the GWN7816?

The GWN7816 has the same ports and performance but no PoE and a 70W supply. The GWN7816P adds a 740W PoE budget.
