SG220-28MP-K9-UK is a Layer 2 smart-managed switch with 24 Gigabit PoE+ copper access ports and four fixed 1G SFP uplinks. Its full-width 1U chassis serves small-business networks connecting IP phones, wireless access points, and surveillance cameras. The Cisco 220 Series Smart Switches combine configurable traffic controls with endpoint power delivery rather than operating as unmanaged devices. Compared with the discontinued SG220-26P-K9-UK and its 180W endpoint allocation, the SG220-28MP provides a larger shared power budget. Automatic voice VLAN assignment applies voice-specific traffic handling, while CDP and LLDP-MED support endpoint discovery and voice configuration. Access control lists restrict traffic by address or protocol where connections require more than basic Ethernet forwarding.

56 Gbps switching capacity supports the port fabric, and 41.67 Mpps forwarding describes processing with 64-byte packets. 375W of shared PoE capacity requires simultaneous endpoint demand to be sized across the connected devices. SG220-28MP-K9-UK includes 128 MB of DRAM and 32 MB of flash for management software and stored images. A 4.1 Mb packet buffer is dynamically shared across ports, while the 8192-entry MAC table maintains learned Ethernet destinations. STP/RSTP/MSTP provide loop control, and LACP supports link aggregation; inter-VLAN routing is not provided. Administration includes HTTP/HTTPS, a scriptable CLI over SSH or Telnet, SNMP, and Cisco FindIT Network Manager. Dual software images and configuration files support image selection and retention of a stable configuration. Support for 256 simultaneous VLANs separates switched traffic, while IGMP snooping limits multicast delivery to requesting receivers.
Specify SG220-28MP-K9-UK as new sealed or certified refurbished, and confirm the power cord, mounting hardware, and required optics on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port, and PoE output under load on every powered port; firmware is verified and configuration is wiped to factory default. ORM covers new units with up to a 3-year extended warranty and certified refurbished units for up to 1 year, with 30-day returns on every condition, terms apply; Cisco's limited lifetime hardware warranty remains subject to eligibility and its July 31, 2027 support cutoff. Enterprise and volume purchases can use PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA across the UK, EU, US, and MEA.

During a phased rollout of phones, access points, and cameras, endpoint maximum draw matters before the final installation stage. Individual powered ports support 30W, but simultaneous demand must fit the shared allocation. Specify each device's requested power and the intended concurrent population before approving the PO.
When several sites need the same switch configuration, editable text configuration files support reuse between units rather than separate manual setup for every device. CLI privilege levels 1 and 15 separate access rights. Specify the approved configuration, administration method, and staging scope with the hardware order.
10G uplinks to distribution
SG220-28MP-K9-UK limits each fixed uplink to 1 Gbps. CBS220-24FP-4X-UK retains 24 PoE+ access ports and provides four 10G SFP+ uplinks for higher-speed distribution connections.
Inter-VLAN routing on the switch
SG220-28MP-K9-UK forwards Layer 2 traffic and does not provide inter-VLAN routing. IPv4 and IPv6 management support does not make the hardware a routed-access switch.
Silent fanless operation
SG220-28MP-K9-UK uses three speed-controlled fans, with acoustic output reaching 52.6 dB above 40°C. The chassis is not fanless, including when endpoint power demand is low.

SG220-28MP-K9-UK is the regional ordering code for the 220 Series Gigabit PoE+ smart switch. SG220 identifies the Gigabit family; 28MP identifies 24 copper access ports, four SFP uplinks, and a 375W budget. The -UK suffix covers the United Kingdom and other designated markets.
The Cisco 220 Series Smart Switch supports HTTP/HTTPS browser management, console access, CLI sessions over SSH or Telnet, SNMP versions 1, 2c, and 3, and Cisco FindIT Network Manager. Cisco FindIT Network Discovery Utility supports discovery, while FindIT Network Manager and Probe support centralized administration.
SG220-28MP-K9-UK provides a 375W shared budget across 24 PoE+ ports, with a maximum of 30W per port. All 24 ports at 30W would require 720W, so maximum output is not available everywhere simultaneously. Size the concurrent endpoint load rather than using port count alone.
The SG220-28MP accepts Gigabit SFP modules in its four fixed uplink slots. MGBSX1 supports multimode fiber links to 550 m, and MGBLX1 supports single-mode fiber links to 10 km. MGBT1 provides a copper connection to 100 m. Match module media, distance, and the remote interface before ordering.
No, the SG220-28MP provides Layer 2 switching rather than inter-VLAN routing. IPv4/IPv6 dual-stack support serves management, while VLANs, access control lists, and multicast snooping control switched traffic. A separate routing device is required when traffic must pass between different IP subnets or VLAN interfaces.
The SG220-28MP mounts in a rack and uses an internal supply accepting 100-240V AC. Its chassis measures 440 mm wide, 44 mm high, and 250 mm deep, with a weight of 4.26 kg. The original package includes mounting hardware, a power cord, and a console cable.
Yes, SG220-28MP-K9-UK is discontinued: end of sale was July 30, 2022, and the last date of support is July 31, 2027. Software maintenance ended July 30, 2023, so remaining hardware support does not mean continued bug-fix development. CBS220-24FP-4G-UK is the replacement for new purchases.
ORM Systems offers SG220-28MP-K9-UK new sealed or certified refurbished, with up to 3-year extended coverage for new units and up to 1 year for refurbished units. Returns are 30 days in either condition; terms apply. Cisco's limited lifetime hardware warranty has one-year fan and power-supply limits; Cisco service ends July 31, 2027.
SG220-28MP-K9-UK allocates 375W to powered endpoints, where SG220-26P-K9-UK allocates 180W. Both are discontinued Gigabit PoE+ models with 24 copper access ports. The 180W model serves lower-power installed configurations; the 375W model accommodates configurations requiring more aggregate endpoint power within the same copper access-port count.
SG220-28MP-K9-UK has 24 copper access ports, whereas SG220-50P-K9-UK has 48; both models are discontinued. The difference is copper endpoint density, not additional fiber access connections. The 24-port model suits an existing 24-port access layout, while the 48-port model addresses a higher endpoint count per chassis.
CBS220-24FP-4G-UK supports direct Cisco Business Dashboard and mobile-app management, while SG220-28MP-K9-UK supports Cisco FindIT Network Manager. The current replacement does not require a separate on-site Dashboard Probe appliance or virtual machine. Existing FindIT-managed installations and new Business Dashboard rollouts therefore have different management and staging requirements.
