Running a small office or shop often means many devices need network and power. When cables are tangled and power adapters are scattered, the desk looks messy and the network slows down. The LevelOne (GEP-2821) PoE unmanaged switch solves this by giving both data and power through a single cable, keeping everything neat and fast. It also supports gigabit speeds so video and files move quickly.
LevelOne (GEP-2821), ,Gigabit Ethernet (10/100/1000), PoE Unmanaged Switch with LevelOne
Upgrade your network without a technician. The LevelOne (GEP-2821) Gigabit Ethernet PoE Unmanaged Switch with LevelOne delivers 28 ports of fast, reliable connectivity in a single rack unit. It is perfect for businesses that need to power cameras, phones, and access points while keeping the cost low.
Usages
Use this switch in a small office to connect computers, VoIP phones, and Wi-Fi access points. In a retail store it can power security cameras and digital signage from the same port.
