GEP-2821 28-Port Gigabit PoE Switch, 802.3af/at PoE, 24 PoE Outputs, 390W Power Budget, 2 Gigabit RJ45 and 2 Gigabit SFP Uplink Ports
The LevelOne GEP-2821 is a 28-port unmanaged Gigabit PoE switch designed for growing office, building and campus networks that need reliable power and data for a large number of IP devices. It provides 24 x 10/100/1000Mbps PoE ports for IP cameras, VoIP phones and wireless access points, plus 2 x Gigabit RJ45 and 2 x Gigabit SFP uplink ports for high-speed connections to core switches, routers or NVRs.
Fully compliant with IEEE 802.3af/at, the GEP-2821 offers a generous 390W PoE power budget. It supports up to 24 ports at 15.4W or 13 ports at 30W, giving flexible power allocation for standard and high-power PoE devices. Built-in 6kV surge and 6kV/8kV ESD protection help protect the switch and connected devices in electrically noisy or demanding environments.
Configuration is simplified with front-panel DIP switches that let installers quickly choose between Default and VLAN modes. In VLAN mode, downlink PoE ports are isolated from each other, reducing broadcast traffic and improving security for surveillance and multi-tenant deployments. With plug-and-play operation, wire-speed Gigabit performance and robust hardware protection, the GEP-2821 is a cost-effective choice for expanding or upgrading PoE infrastructure.

| Features. |
Dip switch Features: ● Default mode: This mode provides standard switch operation with normal network communication and PoE functionality. ● VLAN mode: In this mode, ports 1-24 are isolated from each other and can only communicate with the uplink ports 25-28. This configuration helps prevent network storms. Flow control is enabled in this mode. Protection Features: ● Surge Protection 6KV, Standard IEC61000-4-5 ● ESD Protection 6KV, contact / 8KV: air, Standard IEC61000-4-2 |
