SF90D-05 is a fanless, unmanaged Layer 2 desktop switch with five 10/100 Mbps RJ-45 ports for small-business copper Ethernet connections. All network connections use those built-in ports; there is no separate fiber uplink or expansion bay. The Cisco 90 Series Unmanaged Switches serves computers, printers, copiers, and other office equipment needing basic local connectivity. Connected equipment requires its own power because the ports do not provide PoE. The retired SF90D-08 has eight 10/100 Mbps ports instead of five, distinguishing the nearest higher-density sibling. Within the Cisco Small Business range, this model is a compact Fast Ethernet option for an existing connection requirement, not a Gigabit access switch. Match endpoint speeds and the required physical connections before selecting this configuration.

0.8 Gbps switching capacity defines the aggregate switching limit for traffic crossing the copper ports. 0.74 Mpps forwarding at 64-byte packets specifies packet-processing throughput rather than an uplink speed. Four hardware queues handle 802.1p priority traffic, using priority queuing and weighted round-robin scheduling to distinguish traffic classes automatically. Store-and-forward switching prevents damaged packets from being forwarded, while head-of-line blocking prevention addresses queue interference. SF90D-05 negotiates link speed and half- or full-duplex operation independently on each port; automatic MDI/MDI-X handles cable orientation without a crossover-cable selection step. Energy Efficient Ethernet reduces link activity during quiet periods without operator intervention. The chassis accepts 12V DC at 500mA from the external adapter, so the supplied power connection must accompany the unit. The 0°C to 40°C operating range requires checking ambient conditions before installation.
Select SF90D-05 as new sealed or certified refurbished, and specify the condition and supplied adapter on the PO. 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. ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's original limited lifetime hardware warranty and service ended December 31, 2020. For enterprise and volume orders, POs are accepted, government buyers have Net-30 terms, and RMA with advance replacement is available.

When staging older computers, printers, or copiers on an existing copper network, reserve Category 5 or better UTP cables for the bench connections. Connected devices need Ethernet network adapters and a working TCP/IP environment. Specify the required cable quantities and confirm endpoint compatibility with the switch before the PO.
When maintaining a spare for an installed unit, match the complete part number and retain a compatible local power arrangement rather than substituting on port count alone. ORM Systems provides regional stock and RMA handling in the UK, EU, US, and MEA. Specify the destination region and required condition before ordering.
When small offices need a switch placed away from a desk surface, the desktop models support wall mounting, including under-desk placement. Physical placement therefore belongs in the purchase requirement, not just the installation plan. Confirm mounting hardware is included and identify the installation location on each site's order before the PO.
Gigabit connections to every endpoint
SF90D-05 stops at 100 Mbps on every copper port. CBS110-5T-D provides five Gigabit Ethernet ports in a desktop chassis and is the current upgrade option.
Switch-supplied power for connected endpoints
SF90D-05 has no PoE output. CBS110-8PP-D provides four powered ports within a shared 32W budget, but changes the configuration to eight Gigabit Ethernet ports.
Direct fiber connections through SFP
SF90D-05 has no SFP cages. CBS110-24T offers two 1G SFP combo ports, but changes the configuration to 26 Gigabit Ethernet ports with shared copper/fiber connections.

SF90D-05 identifies a five-port unmanaged Fast Ethernet desktop switch in the Cisco 90 Series. SF90D identifies the desktop 10/100 configuration, while -05 identifies five ports. Specify the complete designation when matching an installed unit, because other members have different port counts or Gigabit Ethernet connections.
SF90D-05 operates without configuration because it is an unmanaged switch. Connect power and compatible Ethernet devices; each port automatically negotiates its connection speed and duplex operation. Procurement should focus on the physical connections and endpoint requirements rather than assuming an operator-configured network policy system.
Yes, SF90D-05 is discontinued: end of sale was December 9, 2015, and Cisco support ended December 31, 2020. Existing-stock procurement does not restart Cisco service. CBS110-5T-D is the current five-port Gigabit upgrade for buyers replacing the retired Fast Ethernet model.
ORM Systems offers SF90D-05 new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions have 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty is no longer active because Cisco support ended December 31, 2020.
No, SF90D-05 provides Ethernet data connections but does not supply PoE to connected equipment. IP phones, access points, or other powered endpoints require their own power source. For switch-supplied power, CBS110-8PP-D has eight Gigabit ports, four PoE ports, and a shared 32W budget.
No, SF90D-05 has RJ-45 copper connections rather than SFP fiber cages. Optical transceivers cannot be installed in its network ports. CBS110-24T offers two 1G SFP combo connections, but that alternative changes the configuration to 26 Gigabit Ethernet ports and shares each fiber connection with a copper port.
SF90D-05 uses an external adapter delivering 12V DC at 500mA. The adapter accompanies the switch rather than an internal AC supply. Include confirmation of the supplied adapter and the destination's mains connection in the PO, particularly when procuring a replacement for an existing unit.
Yes, the Cisco SF90D-05 5-Port 10/100 Desktop Switch supports wall mounting as well as desktop placement. The chassis measures 110 mm wide, 75 mm deep, and 30 mm high. Confirm the supplied mounting hardware and installation position before ordering for an under-desk or wall location.
The Cisco 90 Series Unmanaged Switches are fanless, including SF90D-05, so there is no cooling-fan noise. Passive cooling does not remove the environmental limits: keep operation within 0°C to 40°C. Check the intended mounting location's ambient conditions rather than treating a quiet chassis as unrestricted placement.
The Cisco 90 Series Unmanaged Switches provide four hardware queues with 802.1p priority-based traffic handling. Priority queuing and weighted round-robin scheduling operate automatically. This is built-in traffic prioritization rather than an operator-configured policy system, so purchase decisions should not assume adjustable queue rules or management settings.
SF90D-08 has eight 10/100 Mbps ports, while SF90D-05 has five. Both are unmanaged desktop models from the retired Cisco 90 Series. The five-port unit matches a smaller existing connection count; the eight-port unit represents the higher-density legacy configuration for an installed spare requirement.
SF90-24 uses an internal 100–240V AC supply, whereas SF90D-05 uses an external adapter supplying 12V DC at 500mA. SF90-24 also has 24 ports, not five. Both are retired models: compare them for an existing internal-AC installation versus a compact externally powered replacement.
CBS110-5T-D provides five 10/100/1000 Mbps ports where SF90D-05 provides five 10/100 Mbps ports. CBS110-5T-D is the current upgrade option, while SF90D-05 is retired. The former suits a new Gigabit requirement; the latter is a legacy match for an existing Fast Ethernet installation.
