Ubiquiti\'s ER-4 is a 4-port Gigabit EdgeRouter with fibre uplink capabilities. Boasting three networking Gigabit Ethernet Ports and one SFP port, the ER-4 is capable of routing up to 3.4 million packets per second. This compact, fanless device is best suited for SOHO deployments but it can be deployed in rack mounts using the ER-RMKIT (sold separately).

The ER-4 has no PoE capability. The device is powered via an IEC cable connected directly to the mains.

The ER-4 can be managed remotely using Ubiquiti\'s Network Management System (UNMS) via a PC or tablet, or by the UMobile App on an iOS or Android phone.
