SF90D-05-SG is a compact Cisco 90 Series unmanaged Fast Ethernet switch with 5 fixed 10/100 RJ-45 access ports for small-business network connections. Its desktop enclosure is fanless, with no configuration interface, software installation or management login needed for normal operation. Connections negotiate their operating speed and duplex mode automatically, and auto MDI/MDI-X handles common straight-through and crossover Ethernet cabling. The unit uses a supplied external 12V DC adapter rather than an internal AC supply. Small office desks, checkout areas and low-density equipment groups can connect computers, printers and other wired devices without a managed switch. An alternative within the same 90 Series, SF90D-08-AS, offers 8 access ports instead; port density is the principal choice between these compact desktop models.

0.8 Gbps switching capacity handles the model's aggregate Fast Ethernet switching workload, and 0.74 Mpps forwarding capacity applies to 64-byte frames. The switch uses store-and-forward packet handling to avoid forwarding damaged frames; head-of-line blocking prevention is included in the family. Four hardware queues support automatic traffic prioritization, with priority queuing and weighted round-robin scheduling for traffic classes. Ethernet ports perform automatic speed and duplex negotiation, and the design does not provide configurable VLAN, routing or management interfaces. SF90D-05-SG supports 9216-byte jumbo frames and Energy Efficient Ethernet behavior during quiet link periods. The operating temperature range is 0°C to 40°C, so the installation location must remain within normal indoor equipment conditions. Supplied power comes through a 12V DC, 500mA external adapter. The front-panel link and activity indicators provide local connection status, while fanless operation avoids fan maintenance and associated moving parts.
ORM Systems offers SF90D-05-SG in new sealed and certified refurbished condition. Certified refurbished unmanaged switches are inspected and bench-tested for power-on, POST, clean boot and link operation at the rated speed of every physical Ethernet port; the supplied power adapter is checked for rated output. Request the required condition and quantity when placing a purchase order. New hardware is available with up to a 3-year extended ORM warranty, while certified refurbished units include up to a 1-year ORM warranty; returns are accepted within 30 days subject to terms. Government buyers may use Net-30 terms, and ORM supports RMA with advance replacement for enterprise and volume orders. Regional stock and RMA handling covers the UK, EU, US and MEA.

When an office adds desks or peripheral devices without requiring managed networks, the 5 Fast Ethernet ports provide wired connections for computers and printers. Automatic port negotiation removes per-port setup tasks for basic attachment. Confirm that every required device can operate at 10/100 Mbps before the purchase order.
When replacing an aging plug-and-play desktop switch, the fanless Cisco 90 Series model can fit at a workstation or countertop without a network management setup. Its 12V DC external adapter must be included in the replacement kit. Check the physical placement, power adapter and connector count before ordering.
When purchasing a spare for a small remote office, unmanaged behavior avoids maintaining a configuration file for the replacement. The platform is a discontinued 90 Series unit with Cisco support already ended. Specify the exact SF90D-05-SG part number, required condition and regional stock before issuing the PO.
Gigabit Ethernet access connections
All access ports operate at 10/100 Mbps, not 1000 Mbps. A currently supported Gigabit Ethernet desktop switching model is required when endpoints need 1G links.
Configurable VLAN and routing policies
Unmanaged operation provides no configuration interface for VLAN segmentation or routed interfaces. Specify a current managed switch when the deployment requires administratively defined networks.
Power delivery to connected endpoints
The RJ-45 ports do not supply PoE power. Select a currently supported PoE switch and size its available budget against the actual endpoint power requirements.

SF90D-05-SG identifies the Cisco SF90D-05 desktop unmanaged Fast Ethernet switch, a regional ordering form in the Cisco 90 Series. It provides 5 RJ-45 10/100 connections and has no separate fiber or Gigabit uplink. The final regional code distinguishes the specific ordering form rather than a software license tier.
SF90D-05-SG operates as an unmanaged switch without configuration. There is no switch web management interface, command-line administration, management dashboard or app configuration path for this model. Each Ethernet connection negotiates speed and duplex automatically, while traffic-handling functions work without an administrator applying a configuration.
Yes. Cisco ended sales of SF90D-05-SG on 9 December 2015 and the last date of Cisco support was 31 December 2020. The hardware can still be purchased from secondary-market stock, but Cisco's platform service has ended. Buyers must distinguish seller warranty and returns from discontinued Cisco support.
SF90D-05-SG is offered by ORM Systems as new sealed or certified refurbished. Cisco's limited lifetime hardware warranty is no longer active for this discontinued product after the 31 December 2020 support milestone. ORM offers up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units; 30-day returns apply, subject to terms.
SF90D-05-SG has 5 RJ-45 Fast Ethernet ports operating at 10 or 100 Mbps. All these ports are fixed copper connections, so the switch does not require or accept an uplink module. The available physical port count should be compared with endpoints and any connection to an upstream switch before ordering.
No. SF90D-05-SG does not provide Power over Ethernet on its RJ-45 ports. Connected cameras, access points or telephones requiring PoE must receive power from another suitable source or from a PoE-capable switch instead. This unmanaged model itself uses an external power adapter, not PoE input.
Yes, SF90D-05-SG can connect devices with compatible autonegotiating Ethernet interfaces, but its physical ports operate at Fast Ethernet rates only. A Gigabit-capable device therefore cannot obtain a 1 Gbps connection through this switch. For native Gigabit access speeds, specify a different current Gigabit switch model.
No. SF90D-05-SG starts switching Ethernet frames without a configuration step or management software installation. Automatic negotiation selects the compatible speed and duplex setting for each connected port. The unit is intended for straightforward local connectivity, not deployments requiring centrally administered VLAN membership or routing policies.
No. SF90D-05-SG is a compact desktop switch rather than a 19-inch rack-mount chassis. Its case measures 110 mm wide and 30 mm high and the family offers a wall-mount option. For deployment, allocate a shelf, tabletop or approved wall location with the correct external DC adapter.
SF90D-05-SG has 5 Fast Ethernet access ports, while SF90D-08-AS provides 8. Both belong to the unmanaged desktop Cisco 90 Series and use 10/100 copper ports. The 5-port unit suits installations needing that number of local wired connections; the alternative changes the available port density.
