Cisco SG110-16 16-Port Gigabit Switch: features, specs and who it suits

The Cisco SG110-16 is an unmanaged switch with 16 Gigabit Ethernet ports. It lets you connect computers, printers, network storage and other wired devices to one network without any software setup. It suits small offices and home networks that have run out of ports on the router.

Sixteen Gigabit ports

Each port is rated 10/100/1000, which means it can link at 10 Mbps, 100 Mbps or 1 Gbps, depending on what the connected device supports. In general, the switch negotiates the speed automatically. Older devices and new ones can share the same switch, and each pair of devices communicates at the fastest speed both support.

Gigabit is enough for most office and home uses, such as file sharing, video calls and streaming. For 1 Gbps over copper, cabling of Cat5e or better is typical.

Plug and play

Cisco lists simple setup with no software to install and no configuration needed. You connect the power and your cables, and the switch starts passing traffic. The trade-off with an unmanaged switch is that there is no interface for VLANs or detailed traffic rules. If you need those, look at managed models.

Automatic features

The listing names three features that work without setup:

• Quality of service (QoS): typically gives priority to certain traffic, such as voice, so it isn't held up by bulk transfers.
• Loop detection: helps when a cable is accidentally connected in a circle, which can otherwise flood a network.
• Cable diagnostics: helps you spot cable faults.

Built to last, and fanless

Cisco describes a rugged metal housing and a fanless design. With no fan, the switch makes no fan noise, which suits a desk or a quiet room. Fanless switches typically rely on air moving around the case, so leave some space and avoid enclosed, unventilated spots.

Energy-efficient Ethernet

The switch complies with IEEE 802.3az Energy Efficient Ethernet. This standard typically lets ports draw less power when a link is quiet, which Cisco says optimizes power use and lowers operating cost.

Warranty and support

Cisco lists a limited lifetime warranty and one-year technical support. Check the terms for your region.

Who it suits

It suits small offices, home offices, workshops and anyone setting up a wired network who wants more ports without managing a switch. It measures 11.0 x 6.7 x 1.7 inches, so it's compact enough for a shelf.

What to check before you buy

• Ports: count the devices you need, and leave a few spare for later.
• Management: this switch is unmanaged; check you don't need VLANs.
• Power over Ethernet: the listing doesn't mention it, so check before connecting PoE devices.
• Cabling: confirm your cables support Gigabit speeds.
• Placement: pick a spot with some airflow, as the manual advises.
• Speeds: devices with ports faster than 1 Gbps will be limited to Gigabit.

The short version

• 16 ports of 10/100/1000 Gigabit Ethernet.
• Unmanaged and plug-and-play.
• QoS, loop detection and cable diagnostics.
• Metal housing and fanless design.
• IEEE 802.3az energy-efficient Ethernet and a limited lifetime warranty.
