SG220-50P is a Layer 2 smart managed switch with 48 Gigabit Ethernet PoE+ access ports and two fixed Gigabit combo uplinks for copper or fiber connections. Each combo uplink operates through either its RJ-45 connection or its SFP cage, not both simultaneously. The rack-mount 1U chassis belongs to the Cisco 220 Series Smart Switches family and connects small-business office clients, IP phones, wireless access points, and cameras. This Gigabit PoE+ smart switch supplies endpoint power through network cabling rather than requiring a local adapter at each powered device. The discontinued SG220-50 sibling retains the same access-port density without PoE output, distinguishing powered-endpoint purchases from installations using locally powered equipment.

100 Gbps switching capacity supports Gigabit traffic across the access and uplink connections, while 74.4 Mpps forwarding performance applies to 64-byte packets. 375W of shared PoE capacity requires endpoint allocations to fit the available budget rather than assuming maximum output on every powered port. SG220-50P carries 128 MB of working memory and 32 MB of flash, with dual firmware images supporting upgrade handling. Its 12 Mb packet buffer is shared across all ports, and 8192 MAC entries bound the learned-address capacity. STP/RSTP/MSTP control Layer 2 topology, while LACP supports eight aggregation groups with eight active ports per group. HTTP/HTTPS browser administration, a scriptable CLI, and SNMP provide configuration and monitoring paths. VLAN switching does not provide inter-VLAN routing, so a separate routing device must supply subnet gateways. 427W consumption with PoE provides the upper published input figure for upstream power planning.
Specify new sealed or certified refurbished condition and the required quantity when placing an order for SG220-50P. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. New units carry up to a 3-year extended ORM warranty and certified refurbished units up to a 1-year ORM warranty; both conditions have 30-day returns, terms apply, while Cisco's limited lifetime hardware warranty remains subject to eligibility and ends no later than July 31, 2027. POs are accepted, government orders qualify for Net-30, and RMA with advance replacement is available for enterprise and volume orders.

In a 200-seat corporate head office, the Cisco SG220-50P 50-Port Gigabit PoE Smart Switch powers IP phones and 802.11ac access points with a 370 W PoE budget and centralized management. Its Smart Switch features enable traffic prioritization and rapid failover. Benefit: 30 % faster deployment, reliable high-speed connectivity, and streamlined network operations.
A multi-location retail chain uses the Cisco SG220-50P 50-Port Gigabit PoE Smart Switch to power digital signage displays and HD PoE security cameras across 15 stores. Smart PoE scheduling and VLAN segmentation optimize bandwidth and isolate sensitive video streams. Benefit: continuous 24/7 surveillance, 40 % faster content updates, and enhanced loss-prevention capabilities.
An SMB branch office deploys the Cisco SG220-50P 50-Port Gigabit PoE Smart Switch to segment guest, corporate, and IoT traffic using Layer 2+ features, QoS, and ACLs. PoE port scheduling reduces power consumption during off-hours. Benefit: improved security compliance, 20 % reduction in energy costs, and scalable gigabit performance for up to 50 devices.
When a branch rollout combines IP phones with office clients, automatic voice VLAN assignment and eight hardware queues per port provide configuration points for separating voice traffic. The purchase plan still needs a voice VLAN and a QoS policy consistent with the upstream network. Specify those settings before the order enters staging.
When multiple small-business sites need the same configuration baseline, text-editable configuration files can be downloaded to another switch, while CLI privilege levels 1 and 15 separate operating permissions. A repeat order therefore needs more than matching hardware. Specify the approved configuration file, administrative access requirements, and per-site differences before issuing the PO.
When an installed SG220-50P needs a like-for-like spare, the PO must distinguish unit condition and regional power requirements from a planned migration. ORM offers regional stock and RMA coverage across the UK, EU, US, and MEA. Specify the condition, required cord region, and spare quantity before issuing the maintenance order.
10G uplinks to distribution
SG220-50P's two combo uplinks are limited to Gigabit Ethernet. Neither the copper connection nor the SFP cage provides 10G connectivity, so a 10G distribution requirement exceeds this model's capabilities.
Maximum PoE+ on every access port
The shared 375W budget limits simultaneous endpoint loading, even though individual ports support 30W. SG220-50P cannot sustain maximum PoE+ demand across every powered access port.
Cisco support beyond July 2027
Cisco support for SG220-50P ends July 31, 2027. CBS220-48P-4G-NA is the current North American replacement, retaining 48 Gigabit access ports but changing to four 1G SFP uplinks.

High-performance PoE switch for demanding office environments.
SG220-50P identifies a Gigabit smart-switch model in the 220 Series, with 50 total usable ports and PoE+ capability indicated by P. Those connections consist of 48 powered access ports and two combo uplinks, rather than 50 powered access ports. Each combo uplink offers a choice of copper or fiber.
SG220-50P is managed through an HTTP/HTTPS web interface, a full CLI over SSH or Telnet, SNMP, and Cisco FindIT Network Manager. The browser interface covers configuration, monitoring, and maintenance. Scriptable CLI access and text-editable configuration files support repeated setup tasks, while SNMP provides monitoring integration with network-management tools.
SG220-50P is discontinued: Cisco sales ended July 30, 2022, and the last date of support is July 31, 2027. Software maintenance ended July 30, 2023. Purchasing remaining new stock does not restart those milestones, and Cisco service eligibility remains bounded by the support cutoff and applicable entitlement.
SG220-50P is offered new sealed or certified refurbished, with ORM warranties of up to 3 years extended for new units and up to 1 year for refurbished units. Both conditions have 30-day returns; terms apply. Cisco's limited lifetime hardware warranty remains subject to eligibility and ends no later than July 31, 2027.
SG220-50P replaces SG200-50FP-AU, SG200-50FP-BR, SG200-50FP-EU, SG200-50FP-NA, and SG200-50FP-UK through corresponding regional variants. Those older models reached end of sale in September 2018 and are discontinued. A legacy spare should match the required region; a new migration should follow the current successor rather than stop at SG220-50P.
SG220-50P shares 375W across 48 powered access ports and supports a maximum of 30W per port. Endpoint demand must fit that shared budget; all powered ports cannot simultaneously deliver their individual maximum. PoE and PoE+ devices are supported, with CDP/LLDP power negotiation helping determine individual endpoint allocations.
Cisco 220 Series Smart Switches accept MGBSX1 for 1G multimode links reaching 550 m, MGBLX1 for 1G single-mode links reaching 10 km, and MGBT1 for 1G copper links reaching 100 m. On SG220-50P, each SFP cage shares its uplink with an RJ-45 connection, allowing only one medium at a time.
SG220-50P uses an internal 100-240V AC supply and consumes 427W with PoE at 220V or 426W with PoE at 110V. The corresponding system-only figures are 63.2W and 59.4W. Upstream power planning should distinguish the switch's own operation from the additional input required when delivering power to connected endpoints.
Cisco 220 Series Smart Switches support rack mounting, and SG220-50P occupies 1U with a mounting kit included in its original package. The chassis measures 440 mm wide, 44 mm high, and 350 mm deep and weighs 5.28 kg. Confirm cabinet depth, cable clearance, and included mounting hardware before ordering.
No, SG220-50P is a Layer 2 switch rather than an inter-VLAN router. VLAN configuration and IPv4/IPv6 management support do not provide routed forwarding between endpoint subnets. A separate routing device must supply gateways for the access VLANs; selecting this PoE+ model does not add a Layer 3 software tier.
SG220-50P provides PoE+ on its 48 access ports, whereas SG220-50 has no PoE output. Both models are discontinued. The powered model suits phones, access points, and cameras receiving power through network cables; the nonpowered model suits locally powered endpoints when a like-for-like Gigabit replacement is required.
SG220-50P has 48 Gigabit access ports, whereas SG220-26P has 24 Gigabit access ports. Both are discontinued PoE+ models, making this a port-density comparison for legacy procurement rather than a recommendation for a new standard. SG220-50P suits a larger endpoint count; SG220-26P suits a smaller existing installation.
SG220-50P has two 1G combo uplinks, whereas current replacement CBS220-48P-4G-NA has four 1G SFP uplinks. SG220-50P is discontinued, and the replacement retains 48 Gigabit access ports. The legacy model suits like-for-like sparing, while CBS220-48P-4G-NA suits North American migration orders requiring the successor's separate fiber uplink connections.
