Level One GEP-2421W150 User Manual

GEP-2421W150 Version: 1

24-Port Gigabit PoE Switch, 802.3at/af PoE

The LevelOne GEP-2421 series are unmanaged Gigabit PoE switches with 24 RJ45 PoE ports. The
switches are IEEE 802.3af/at compliant, providing power and data over a single Ethernet cable to any PoE
device, with a total power budget of 150/250/380/500/630W, or up to 30W per port. Ideal for desktops, they
are also 19-inch rack-mountable, which provides convenient and flexible installation. The GEP-2421
switches are designed for small-to-medium businesses that require an affordable solution for deploying
PoE infrastructure.
