SF100-16-NA provides unmanaged Layer 2 connectivity through sixteen 10/100 RJ-45 ports for small-office computers, printers and copiers. The desktop chassis has no dedicated uplink ports or optical cages, so an upstream connection uses an ordinary Ethernet port. The Cisco 100 Series Unmanaged Switches family serves basic office networking rather than configurable campus access. This model is non-PoE, so connected endpoints need separate power. The discontinued SF100D-16P differs by providing eight powered ports. For an existing installation, the principal distinction is straightforward copper switching without a configuration requirement, rather than endpoint power delivery or a separate high-speed uplink connection.

3.2 Gbps switching capacity defines the aggregate switching ceiling, while 1.4 Mpps forwarding with 64-byte packets supplies the separate packet-processing limit. Four hardware queues support traffic prioritization, and priority queuing with weighted round-robin scheduling handles service differentiation automatically. Store-and-forward switching checks packets before forwarding and prevents damaged packets from passing through the network. SF100-16-NA uses automatic MDI/MDI-X detection for straight-through or crossover Ethernet cabling; each port also negotiates speed and half- or full-duplex operation independently. An internal universal AC supply accepts 100-240V at 50-60Hz, keeping power conversion inside the chassis instead of an external adapter. This Cisco Small Business switch operates from 0°C to 40°C, making enclosure temperature a deployment constraint. UL 60950, CSA 22.2, the CE mark and FCC Part 15 Class A cover safety and electromagnetic compliance.
ORM Systems offers SF100-16-NA in new sealed and certified refurbished condition; refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, a clean boot and internal PSU status. Specify condition, quantity and regional power cord on the purchase order: new orders include up to a 3-year extended ORM warranty, certified refurbished orders up to 1 year, and every condition includes 30-day returns, terms apply. Cisco's hardware warranty and service ended December 31, 2020. Enterprise and volume orders have PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA across the UK, EU, US and MEA.

When an office needs wired connections for existing computers, printers and copiers, include Category 5 or better Ethernet patch cables in the bill of materials. Network cabling is separate from the power connection, so confirm cable quantities and endpoint power arrangements before issuing the purchase order.
When a staging bench will carry jumbo-frame traffic, the 9216-byte frame limit becomes a compatibility check rather than an assumed setting. Connected hosts and the rest of the test path must use compatible frame sizes. Confirm the required frame size across the complete bench before specifying the switch.
Gigabit speeds on every connection
SF100-16-NA connections stop at 100 Mbps. CBS110-16T-NA provides sixteen Gigabit Ethernet ports and is the current endpoint of the replacement chain.
Power for phones over Ethernet
SF100-16-NA supplies data connectivity only and cannot power connected phones or access points. Endpoint power must come from separate supplies or a PoE-capable switch.
Fiber connections through optical transceivers
SF100-16-NA has copper Ethernet connections only. Optical transceivers cannot be installed because the chassis has no fiber cages or removable uplink module bay.

SF100-16-NA identifies an ordering form of the SF100-16 16-Port 10/100 Switch. SF100-16 belongs to the Cisco 100 Series Unmanaged Switches family, and 16 is the Ethernet port count. Preserve the complete SF100-16-NA identifier when matching an existing order rather than substituting another regional form.
SF100-16-NA operates without configuration and requires no setup software. Port speed and duplex negotiation, cable-type detection and traffic prioritization work automatically. Connect the Ethernet devices and AC power; operation does not depend on an administrator configuring individual ports before the unit can forward traffic.
No, SF100-16-NA has sixteen 10/100 copper Ethernet ports and no separate uplink connections. An upstream network connection uses one of those ordinary ports. The chassis does not accept optical transceivers or removable uplink cards, so the upstream connection remains copper Fast Ethernet.
Cisco 100 Series switches prioritize traffic automatically using four hardware queues, priority queuing and weighted round-robin scheduling. Class of service uses 802.1p priority information. These functions operate without configuration, so buyers should distinguish automatic traffic handling from an administratively configurable quality-of-service policy.
SF100-16 measures 279.4 mm wide, 44.5 mm high and 170 mm deep, with a weight of 1.25 kg. The compact chassis is narrower than a full-width 19-inch switch. Check the available mounting space and the mounting hardware included with the selected order condition.
SF100-16-NA requires a 100-240V AC connection to its internal universal power supply, operating at 50-60Hz. Power conversion is inside the chassis rather than in an external DC adapter. Specify the appropriate regional power cord with the order and provide separate power for connected endpoints.
Yes, SF100-16-NA is discontinued: end of sale was December 9, 2015, and Cisco support ended December 31, 2020. The direct replacement SF110-16-NA is also discontinued. Following that replacement chain leads to CBS110-16T-NA, which changes the connection speed from Fast Ethernet to Gigabit Ethernet.
SF100D-16P provides eight PoE ports with a shared 64W budget, whereas SF100-16-NA does not supply PoE. Both are discontinued sixteen-port Fast Ethernet models. For installed-equipment matching, SF100D-16P serves Ethernet-powered endpoints; SF100-16-NA serves equipment with separate power. Neither model provides a current Cisco-supported replacement path.
SF100D-16 uses an external 12V DC supply, whereas SF100-16-NA accepts AC through an internal universal supply. Both provide sixteen 10/100 Ethernet connections and are discontinued. For spare matching, SF100D-16 corresponds to an external-adapter installation; SF100-16-NA corresponds to an installation using direct AC input.
CBS110-16T-NA provides sixteen Gigabit Ethernet ports, whereas SF100-16-NA is limited to sixteen 10/100 ports. CBS110-16T-NA is the current endpoint of the replacement chain through the discontinued SF110-16-NA. The older model matches Fast Ethernet spares; the current model suits buyers requiring Gigabit connectivity.
ORM Systems offers SF100-16-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Every condition includes 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty, including its 1-year power-supply limit, is no longer active: Cisco warranty and service ended December 31, 2020.
