Grandstream GWN7803PH Pro 24-Port High-Power PoE Layer 2 Managed Switch

The GWN7803PH Pro scales the same Layer 2++ managed switch platform down to 24 Gigabit ports, all of which support PoE/PoE+/PoE++, giving it a 400W power budget across 2 SFP+ uplinks. It's a good fit for branch offices or single-floor deployments where 48 ports would be overkill but you still need serious PoE headroom.

It runs a single-core version of the same interAptive CPU platform, with 256MB RAM and 32MB flash, enough to handle VLAN segmentation, QoS, and IGMP/MLD Snooping without lag. Switching capacity is 72 Gbps with sub-4μs latency, and the switch supports the same enterprise security stack found across the Pro line, including DoS protection, IP Source Guard, and DHCP Snooping.

Management options mirror the rest of the family: local Web UI, GDMS Networking cloud platform, GWN Manager, or CLI.
