SF100D-05-NA is a fanless, unmanaged Layer 2 desktop switch with five 10/100 RJ-45 connections for small-business networks. The Cisco 100 Series Unmanaged Switches range connects computers, printers, copiers, and other wired office equipment without configuration. Copper connections handle both endpoints and upstream connectivity: there is no dedicated uplink or fiber expansion bay, so the upstream cable occupies one of the available connections. Connected devices require independent power because this model supplies no PoE. The discontinued SF100D-08P adds endpoint power and increases the connection count to eight. The purchasing distinction is between retaining existing Fast Ethernet connectivity and introducing faster access or switch-powered endpoints.
SF100D-05-NA price for new stock is $62.48. SF100D-05-NA refurb price is $117.00. SF100D-05-NA is in stock and available for next-day dispatch. (terms applied)

1 Gbps switching capacity provides the fabric for local Ethernet traffic, while 0.74 Mpps forwarding performance specifies packet handling with 64-byte frames. Four hardware queues separate traffic priorities, and 802.1p priority handling works with priority queuing and weighted round-robin scheduling to service those queues automatically. SF100D-05-NA uses store-and-forward switching to reject damaged packets before forwarding them to another connection. Head-of-line blocking prevention addresses queue contention, while 9216-byte jumbo-frame support accommodates larger frames where connected equipment supports them. The Cisco Small Business unit also supports 802.3x flow control for Ethernet traffic handling. Energy Efficient Ethernet under IEEE 802.3az reduces active-link energy use during quiet periods. Automatic QoS handles delay-sensitive voice and video traffic without a manually configured traffic policy. These traffic-handling mechanisms run automatically rather than through user-defined switch settings.
ORM Systems offers SF100D-05-NA new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, clean boot, every port linking at rated speed, and the supplied adapter delivering rated output. Specify the condition and North American power arrangement on the PO; ORM warranties provide up to 3-year extended coverage on new hardware and up to 1 year on certified refurbished hardware, with 30-day returns on every condition, terms apply. Cisco's former limited lifetime hardware warranty ended with Cisco service on December 31, 2020. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement.

When an office adds a connection point for existing wired equipment, automatic MDI/MDI-X removes the need to select a crossover cable. Category 5 or better copper cabling is required. Inventory the installed patch leads and specify any additional cable quantities before the purchase order.
When spare units are staged before installation, storage conditions differ from the conditions used during operation. Unpowered inventory tolerates -20°C to 70°C, with 10% to 90% relative humidity, noncondensing. Specify appropriate storage handling and confirm the eventual installation environment before releasing staged equipment against the purchase order.
Gigabit Ethernet endpoint connections
SF100D-05-NA connections stop at 100 Mbps. CBS110-5T-D-NA is the current successor with five Gigabit Ethernet connections while retaining a desktop enclosure and external power.
Powering phones or access points
SF100D-05-NA supplies no PoE through its Ethernet connections. Phones or access points requiring switch-delivered power cannot receive their operating power from this model.

SF100D-05-NA identifies a Cisco 100 Series Fast Ethernet desktop switch with five connections and North American localization. SF100D identifies the Fast Ethernet desktop model within the series, 05 specifies five ports, and NA identifies the regional version. The complete ordering identity distinguishes this unit from larger or powered models.
Cisco 100 Series Unmanaged Switches operate without configuration, and SF100D-05-NA requires no setup of network settings before use. Connect power and Ethernet cables, then allow automatic link negotiation to establish connections. Automatic traffic handling is built in rather than applied through a user-configured switch policy.
Yes, SF100D-05-NA is discontinued: Cisco sales ended December 9, 2015, and support ended December 31, 2020. The first successor, SF110D-05-NA, is also discontinued. CBS110-5T-D-NA is the current replacement when purchasing requires a successor rather than an additional legacy unit for an existing installation.
SF100D-05-NA is offered new sealed with an up to 3-year extended ORM warranty or certified refurbished with up to 1 year; both have 30-day returns, terms apply. Cisco's former limited lifetime hardware warranty ended with Cisco support on December 31, 2020.
SF100D-05-NA uses an external adapter supplying 12V DC at 500mA rather than an internal AC power supply. The NA ordering version identifies North American localization. Confirm the supplied adapter and regional power arrangement on the order, particularly when replacing an installed unit whose original adapter will not be reused.
No, SF100D-05-NA has no dedicated uplink or SFP cage; upstream connectivity uses one of the five 10/100 RJ-45 connections. An upstream cable therefore occupies a connection that could otherwise attach an endpoint. The chassis has no removable uplink module bay, so optics cannot add a fiber connection.
No, SF100D-05-NA does not deliver PoE to phones, access points, or cameras. Its Ethernet connections carry data, so attached equipment must receive power independently. A purchase intended to replace separate endpoint power with switch-supplied power therefore requires different hardware rather than a change to this unit.
Cisco 100 Series desktop models, including SF100D-05-NA, support desktop placement and wall mounting rather than a full-width rack chassis. The enclosure measures 92.6 mm wide, 27 mm high, and 90.6 mm deep, with a 0.22 kg weight. Confirm the mounting hardware and placement requirements with the order.
SF100D-08P provides four PoE ports, while SF100D-05-NA does not supply endpoint power. The PoE model also has eight connections rather than five and shares a 33.12W power budget. Both are discontinued; the former serves legacy powered-endpoint installations, while the latter fits separately powered equipment.
SF100D-08 has eight 10/100 connections, compared with five on SF100D-05-NA. Neither model supplies PoE, and both belong to the discontinued 100 Series. The eight-port model fits legacy installations needing more local connections; the five-port model fits installations with fewer wired links to accommodate.
CBS110-5T-D-NA provides five Gigabit Ethernet connections, whereas SF100D-05-NA provides five 10/100 connections. Both use a desktop chassis and external power. The current successor suits purchases requiring gigabit access; the discontinued older model addresses replacement demand where the existing Fast Ethernet connection speed remains sufficient.
