Description

A silent 10G switch for the desk

With no fan, the device can sit in a study or living room where server cabinet noise would be out of place. Dual boot lets you pick the simple SwOS with switch-only features or RouterOS, which adds routing and Layer 3 functions. The system can be switched from RouterOS, from SwOS or in the RouterBOOT loader settings.

Who this network switch is for

A home lab, video editing studio or small office where two or three computers and a NAS need 10 Gbit/s links between them. The gigabit port connects to the regular network or router and serves for management.

Is it quiet?

Yes, there is no fan inside and cooling works through the metal housing, so it makes no sound while running.

How is the device powered?

The two DC jacks take 12–57 V, with the second one for redundancy. Power can also come over PoE on the management port under 802.3af/at. Whether an adapter is included, the manufacturer does not specify.
