SG220-28MP-K9-NA combines 24 Gigabit PoE+ copper access ports with four dedicated 1G SFP uplinks in a rack-mount 1U chassis. This Layer 2 smart-managed member of the Cisco 220 Series connects office computers and powers compatible phones, wireless access points, and IP cameras. The fiber connections do not share their interfaces with copper access ports, distinguishing this configuration from models using combo uplinks. Compared with the discontinued SG220-26P-K9-NA, the higher aggregate PoE allocation addresses larger combined endpoint power requirements. Browser-based configuration and monitoring provide local administration for buyers maintaining an existing small-business network. The uplink architecture is fixed rather than an empty bay requiring a removable network card.

56 Gbps switching capacity and 41.67 Mpps forwarding at 64-byte packet sizes provide separate bandwidth and packet-rate limits for traffic planning. 375W of shared PoE output requires allocation across the connected powered devices. SG220-28MP-K9-NA combines 128 MB of memory, 32 MB of flash, and an 8192-entry MAC table for its switching and management functions. Within the small and midsize business portfolio, support for 256 simultaneous VLANs and 512 ACL rules provides traffic segmentation and access restrictions. STP/RSTP/MSTP control Layer 2 loops, while LACP supports link aggregation. IGMP snooping directs multicast traffic toward requesting receivers. A dynamically shared 4.1 Mb packet buffer and eight hardware queues per port support traffic handling, with strict-priority and Weighted Round-Robin scheduling available for QoS. Routing between VLANs requires a separate routing device.
SG220-28MP-K9-NA is offered new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, optics bay recognition checked, firmware verified, and configuration wiped to factory default. Specify condition, quantities, and accessory requirements on the PO: new orders carry up to a 3-year extended warranty, certified refurbished orders up to 1 year, and every condition includes 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty remains subject to entitlement and is bounded by July 31, 2027. ORM Systems accepts POs, offers Net-30 for government and RMA with advance replacement, and provides regional stock and RMA support across the UK, EU, US, and MEA.

When several offices need repeatable configurations, SG220-28MP-K9-NA supports text-editable configuration files and a scriptable CLI with privilege levels 1 and 15. Prepare a shared baseline, separate location-specific settings, and specify configuration review and staging requirements alongside the per-site quantities before issuing the purchase order.
When firmware must be validated before hardware reaches a production site, the Cisco 220 Series can retain two firmware images and a mirror configuration file. Identify the intended image and saved configuration in the staging plan, then specify firmware verification and clean-boot testing requirements on the order.
10G uplinks to distribution
SG220-28MP-K9-NA limits its four dedicated uplinks to 1G. The current Cisco Business 220 Series includes configurations with fixed 10G SFP+ uplinks for faster distribution connections.
More than 30W per endpoint
SG220-28MP-K9-NA supplies a maximum of 30W on each powered port. The aggregate PoE budget does not increase the power ceiling available to an individual endpoint.
Cisco support beyond July 2027
SG220-28MP-K9-NA reaches its last date of Cisco support on July 31, 2027. CBS220-24FP-4G-NA is the current replacement; new sealed stock does not restart the older model's support lifecycle.

SG220-28MP-K9-NA identifies a regional Cisco 220 Series Gigabit PoE+ smart switch with 24 copper ports and four SFP ports. SG220 denotes the Gigabit model family; 28MP identifies this 28-port, 375W configuration. NA covers the United States, Canada, Mexico, and other designated Latin American markets.
The Cisco 220 Series supports HTTP/HTTPS browser management, CLI access over SSH or Telnet, SNMP, Cisco FindIT Network Discovery Utility, and Cisco FindIT Network Manager with Probe. The browser interface provides configuration and monitoring, while the scriptable CLI supports automated administration. Select the access method and authentication settings before staging.
SG220-28MP-K9-NA is discontinued: end of sale was July 30, 2022, software maintenance ended July 30, 2023, and the last date of support is July 31, 2027. CBS220-24FP-4G-NA is the current replacement. Purchasing new sealed or certified refurbished stock does not change these Cisco milestones.
ORM Systems offers SG220-28MP-K9-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year; both include 30-day returns, terms apply. Refurbished units are inspected and bench-tested. Cisco's separate limited lifetime hardware warranty is bounded by July 31, 2027, with fans and power supplies covered for 1 year.
SG220-28MP-K9-NA provides a 375W shared PoE budget across 24 ports, with a maximum of 30W per port. Both 802.3af PoE and 802.3at PoE+ endpoints are supported. Connected-device requirements must fit the aggregate allowance; the per-port maximum does not mean every powered port can supply its maximum simultaneously.
SG220-28MP-K9-NA has four dedicated 1G SFP uplinks rather than shared copper/fiber combo connections. MGBSX1 supports multimode fiber links to 550 m, while MGBLX1 supports single-mode links to 10 km. MGBT1 provides a copper connection to 100 m. Specify the required transceiver PID for each populated uplink.
SG220-28MP-K9-NA delivers 56 Gbps switching capacity and 41.67 Mpps forwarding measured with 64-byte packets. Bandwidth and packet rate are separate sizing limits, so retain both when comparing equipment. The switch also supports an 8192-entry MAC table for learned addresses across its Layer 2 switching functions.
SG220-28MP-K9-NA uses an internal AC power supply accepting 100-240V AC at 50-60 Hz. Consumption with PoE is 426W at 110V or 417W at 220V. These electrical-input figures are separate from endpoint output capacity; use the appropriate input figure when sizing the AC circuit and UPS.
The Cisco 220 Series SG220-28MP model fits a rack-mount 1U installation, measuring 440 mm wide, 44 mm high, and 250 mm deep. The original package includes mounting hardware. Three speed-controlled fans provide cooling, and operation requires an ambient temperature between 0°C and 50°C. Confirm required mounting accessories on refurbished orders.
SG220-28MP-K9-NA provides Layer 2 switching rather than routing between VLANs, so inter-VLAN traffic requires a separate routing device. The switch supports 256 simultaneous VLANs and IPv4/IPv6 management functions. IPv6 host support, ACLs, and QoS do not turn this configuration into a routed access switch.
SG220-28MP-K9-NA provides a 375W PoE budget, whereas SG220-26P-K9-NA provides 180W. Both models are discontinued. For legacy replacement purchases, the former accommodates a larger combined powered-device load; the latter suits an existing installation whose endpoint requirements remain within the smaller shared allowance.
SG220-28MP-K9-NA has 24 copper access ports, while SG220-50P-K9-NA has 48. Both configurations are discontinued. For like-for-like legacy replacements, the former matches a smaller endpoint count; the latter addresses installations requiring twice the copper access density. Specify the required access-port count rather than relying on the model number alone.
CBS220-24FP-4G-NA carries 256 MB of memory, compared with 128 MB in SG220-28MP-K9-NA. The older model is discontinued, and CBS220-24FP-4G-NA is its current replacement. The older configuration suits exact-match legacy sparing; the successor is the migration option for buyers moving away from the discontinued hardware.
