Level One GEL-2681 User Manual

GEL-2681 Version: 1

26-Port L3 Lite Managed Gigabit Switch, 2 x
SFP/RJ45 Combo

GEL-2681 L3 Lite Managed Gigabit Switch is a next-generation Ethernet Switch offering full suite of L2
features, including advanced L3 features such as Static Route that delivers better cost performance and
lower total cost of ownership in Enterprise networks via fiber or copper connections. GEL-2681 provides
high HW performance and environment flexibility for SMBs/ Enterprises. GEL-2681 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 Wifi­AP for Enterprise Applications.
