Level One GEP-2851 User Manual

GEP-2851 Version: 1

TURING 28-Port Web Smart Gigabit PoE Switch,
24 PoE Outputs, 4 x SFP, 370W

GEP-2851 Web Smart Gigabit PoE Switch is a next-generation Ethernet Switch offering powerful L2
features, Layer 3 DHCP Server, better PoE functionality and usability that delivers the cost-effectively
business and transports Ethernet services via fiber or copper connections. GEP-2851 delivers 24
(10M/100M/1G) RJ45/PoE+ (Support 802.3at/af, and total up to 370W) ports and 4 GbE SFP ports.
GEP-2851 provides high HW performance and environment flexibility for SMBs and Enterprises. GEP-2851
is ideal to deliver management simplicity, optimum user experience, and lower total cost of ownership. The
embedded Device Managed System is designed to be extremely easy-to-use/manage/install IP Phone, IP
Cam, or Wifi-AP for Enterprise Applications.
