Managed Layer 2 Switch for Small Business

The Sophos CS101-8 is a managed Layer 2 switch with eight RJ45 ports and two SFP uplinks. It delivers Gigabit speeds to wired endpoints and supports up to 256 simultaneous VLANs. The unit is aimed at branch offices, retail sites and SMB networks that need centralised control via Sophos Central.

Fanless Desktop Build with 110 W PoE Budget

A fanless desktop chassis runs silently in office environments and fits on a shelf or wall bracket. Eight PoE+ ports share a 110 W budget, powering up to seven 15.4 W devices or three 30 W devices such as access points or cameras. An external 150 W DC adapter supplies the switch and PoE load.

Upgrade from Unmanaged or PoE-Limited Switches

Replacing an unmanaged switch adds VLAN segmentation, link aggregation and port-based authentication for stronger network hygiene. The jump is worth it when you need to power multiple PoE devices from a single compact unit and manage them through a single cloud dashboard. It does not suit buyers who need Layer 3 routing, stacking or 10 GbE copper ports.

Questions about this item

What Ethernet standard do the eight RJ45 ports use, and what speed does that cap the links at?

The eight RJ45 ports follow IEEE 802.3ab for 10/100/1000 Mbps, so each copper link tops out at 1000 Mbps.

What are the exact dimensions and weight, and does the unit need a rack shelf?

The desktop chassis measures 105 mm x 240 mm x 27 mm and weighs 0.636 kg; it sits on a shelf or desk and does not require rack mounting hardware.

How is the switch powered up, and which step is often missed during first deployment?

Connect the external 150 W DC adapter (100-240 VAC, 54 V/2.78 A) to the switch, then press the On/Off button; the step users forget is pressing that button after plugging in the adapter.
