The EdgeRouter 4 in depth

Fanless four-core routing

The EdgeRouter 4 is a fanless router built around a four-core, 1 GHz MIPS64 processor. It belongs to the EdgeMax family, and its fanless design means there is no cooling fan in the unit.

Copper and SFP connectivity

The ER-4 provides (3) GbE RJ45 ports alongside (1) 1G SFP port. This lets you combine standard copper Ethernet connections with an SFP-based link on the one router.

Flexible mounting

The router can be mounted on a wall or in a rack. Note that the rack-mount accessory is sold separately, so it is not included with the router.
