Description

Product Description

The EMP‑P4815V6 (marketed under similar SKUs such as GNT‑P4815V6) is a 24‑port hybrid PoE switch tailored for environments requiring both high port count and varied power output. It combines 22 10/100 Mbps PoE ports for standard PoE devices with 2 Gigabit PoE ports capable of delivering higher power output, plus 2 Gigabit uplink ports for backbone or router connections.

PoE functionality adheres to IEEE 802.3af/at/bt standards, allowing compatibility with a wide range of cameras, wireless access points, VoIP phones, and other PoE‑enabled network devices. Some ports support higher‑power PoE (up to 60 W) for devices requiring greater wattage. Surge, lightning, ESD, overheating, and short‑circuit protections are built in for reliable long‑term operation.

The switch operates with store‑and‑forward forwarding, maintains an 8K MAC address table, and can achieve up to 130 m transmission distance with PoE in supported extend mode. Its unmanaged design provides plug‑and‑play simplicity without the need for configuration.
