Description

Product Description

The EMP‑P4804V6 (also marketed under similar model codes like GNT‑P4804V6) is designed for small business, SOHO, and CCTV surveillance networks that need simultaneous data connectivity and power delivery for network devices. It includes:

• 6 × 10/100 Mbps PoE ports for standard PoE endpoints
• 2 × 10/100/1000 Mbps PoE ports (higher speed)
• 2 × 10/100/1000 Mbps uplink ports for connecting to routers or core switches
• 1 × Gigabit SFP fiber port for extended network uplinks

All ports automatically negotiate speeds and support auto MDI/MDIX. The switch supplies power according to IEEE 802.3af/at/bt PoE standards, delivering up to ~120 W total PoE budget for connected devices. Built‑in protections (lightning, ESD, short‑circuit, over‑temperature) enhance reliability and longevity.
