Eight-port managed desktop switch

The Sophos CS101-8 is a Layer 2 managed switch with eight RJ45 ports and two SFP uplinks for small offices or branch sites. It supports up to 256 simultaneous VLANs from a 4096 ID pool and runs without a fan for silent desktop placement. An external 12V DC adapter powers the unit from 100-240VAC mains.

Sustained load behaviour

Typical idle draw is 3.76W and peaks at 6.96W under full traffic, so heat output stays low during continuous operation. The 20Gbps switching capacity handles aggregated Gigabit streams across all ten ports without oversubscription. An 8K MAC address table maintains forwarding state for growing device counts.

Build and connectivity

The metal enclosure measures 105mm by 240mm by 27mm and weighs 0.636kg, fitting on a shelf or wall bracket with no rack ears required. SFP slots accept 1000Base-SX/LX, copper RJ45 or DAC modules up to five metres. An on/off button allows a hard power cycle without unplugging the adapter.

Questions about this item

How much heat does the CS101-8 produce when running 24/7 at typical load?

At typical maximum load it draws 6.96 W, which equals 23.733 BTU/hr; at idle it drops to 3.76 W or 12.82 BTU/hr, and the fan-less chassis relies on passive cooling.

What cabling and transceivers do I need to use the eight RJ45 ports and two SFP uplinks?

The eight RJ45 ports accept Cat5e or better twisted-pair for 10/100/1000 Mbps; the two SFP slots take 1000Base-SX/LX optics, 1000Base-X copper modules or a 5 m max DAC cable.

Will the CS101-8 interoperate with my older IEEE 802.1D bridges and 802.3u Fast Ethernet gear?

Yes — it supports IEEE 802.1D, 802.1w, 802.1s and 802.3u, so legacy spanning-tree bridges and 100 Mbps devices connect and negotiate automatically.
