SG220-50-K9-EU provides Layer 2 smart-managed switching through 48 Gigabit copper access ports and two fixed Gigabit RJ-45/SFP combo uplinks. The non-PoE design connects endpoints that receive power separately, while its full-width 1U chassis fits a standard equipment rack. Within the Cisco 220 Series, this configuration serves small-business access networks requiring traffic segmentation and configurable security rather than an unmanaged port expansion. VLAN-based separation, access controls, and traffic prioritization support different endpoint groups on the same switch. A built-in browser interface and scriptable CLI provide configuration options for administrators with different operating workflows. The discontinued SG220-50P-K9-EU adds a shared 375W PoE+ budget for installations that already depend on switch-powered endpoints.

100 Gbps switching capacity serves the complete port set, while 74.4 Mpps forwarding at 64-byte packets provides the small-packet throughput figure for traffic sizing. An 8192-entry MAC table accommodates learned endpoint addresses, and 256 simultaneous VLANs support separate broadcast domains. SG220-50-K9-EU carries 128 MB DRAM and 32 MB flash, with a 12 Mb packet buffer shared dynamically across ports. STP/RSTP/MSTP support bridged topologies, while LACP supports eight aggregation groups with eight active ports per group. Eight hardware queues per port provide traffic scheduling, and access control lists support 512 rules for filtering policies. Inter-VLAN routing requires a separate routing device. 39.9W system consumption at 220V provides the switch load for electrical planning. Cooling uses one fan without speed control, so acoustic planning should allow for 40.3 dB operation rather than assuming silent operation beside occupied workspaces.
ORM Systems offers SG220-50-K9-EU new sealed or certified refurbished; refurbished units are inspected and bench-tested, with optics bay recognition checked, firmware verified, and configuration wiped to factory default. Specify condition, regional power cord, mounting hardware, and optics on the PO. ORM provides up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on every condition, terms apply; Cisco's separate limited lifetime hardware warranty ends with support on July 31, 2027. For enterprise and volume purchases, POs are accepted, Net-30 is available for government, and RMA includes advance replacement across UK, EU, US, and MEA.

Where an existing site still uses the discontinued SLM2048T-EU, SG220-50-K9-EU is a named replacement for that older switch. Treat the change as a migration rather than a configuration clone. Check port assignments, existing segmentation, and the required accessory bundle before specifying the replacement order.
During a repeat-site rollout, dual configuration support includes a mirror of the latest stable configuration. Text-editable configuration files support reuse across Cisco 220 Series switches. Keep site-specific addressing and administrator access settings separate from the shared template, and specify staging and configuration review requirements before releasing the purchase order.
When a bench build must reproduce a production fault, port mirroring can copy traffic from eight source ports to one destination, with four sessions supported. Reserve an analyzer connection in the test plan rather than treating monitoring as an afterthought. Specify the required test configuration before ordering.
10G uplinks to distribution
The fixed combo uplinks operate at 1G, not 10G. A distribution connection requiring higher-speed interfaces needs a different switch; installing another transceiver does not increase the supported uplink speed.
Power delivered to connected endpoints
SG220-50-K9-EU provides data-only copper connections and cannot supply endpoint power. Powered phones, cameras, or access points require separate power equipment or a PoE-capable switch.
Silent operation beside occupied workspaces
SG220-50-K9-EU uses one fan without speed control and has a 40.3 dB acoustic rating. A requirement for silent operation calls for a fanless switch.

SG220-50-K9-EU identifies a Cisco 220 Series Gigabit smart switch with 50 logical network ports: 48 copper access ports and two combo uplinks. SG220-50 is the model designation, and EU selects the regional ordering group that includes the European Union. Each combo uplink shares copper and SFP connectivity.
SG220-50-K9-EU supports an HTTP/HTTPS web interface, a scriptable CLI, SSH or Telnet access, and SNMP versions 1, 2c, or 3. Cisco FindIT Network Manager provides centralized management, while the FindIT Network Discovery Utility locates devices and displays identification information. These are management options for the original Cisco 220 Series.
Yes, SG220-50-K9-EU reached end of sale on July 30, 2022, and Cisco support ends July 31, 2027. Software maintenance ended July 30, 2023, so continued hardware operation does not mean ongoing bug-fix development. CBS220-48T-4G-EU is the current replacement for this regional ordering form.
New sealed and certified refurbished SG220-50-K9-EU units carry ORM warranties of up to 3 years extended and up to 1 year, respectively. Every condition includes 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty is bounded by July 31, 2027; fans and power supplies originally carry 1-year coverage.
SG220-50-K9-EU replaces discontinued SLM2048T-EU, the SG200-50 50-Port Gigabit Smart Switch. SLM2048T-EU reached end of sale on October 4, 2018, and Cisco support ended October 31, 2023. Treat that replacement as a configuration migration, not as assurance that the older switch's configuration file transfers unchanged.
SG220-50-K9-EU has no PoE output, whereas discontinued SG220-50P-K9-EU supplies 48 PoE+ ports from a shared 375W budget. Both models are end of sale. For legacy fleet sparing, the non-PoE model matches separately powered endpoints, while the PoE model matches installations that depend on power delivered through network ports.
SG220-50-K9-EU provides 48 Gigabit copper access ports, whereas discontinued SG220-26-K9-EU provides 24. Both retain two Gigabit combo uplinks and both are end of sale. The higher-density model suits existing fleets requiring more copper terminations; the smaller model matches legacy installations built around fewer access connections.
CBS220-48T-4G-EU provides four dedicated 1G SFP uplinks, whereas SG220-50-K9-EU uses two 1G RJ-45/SFP combo uplinks. CBS220-48T-4G-EU is the current replacement; SG220-50-K9-EU is discontinued. Existing-fleet spares can retain combo connectivity, while a replacement build requiring separate fiber uplinks should specify the current model.
MGBSX1 and MGBLX1 are supported fiber transceivers for the Cisco SG220-50. MGBSX1 supports multimode connections up to 550 m; MGBLX1 supports single-mode connections up to 10 km. Select optics to match the installed fiber and remote interface, and specify quantities separately from the chassis. Each SFP cage shares its logical port with copper.
No, the Cisco 220 Series provides Layer 2 switching rather than inter-VLAN routing. IPv4/IPv6 dual-stack management, IPv6 host mode, and multicast snooping do not make these switches routers. Traffic moving between VLANs requires a separate routing device, which belongs in the network design rather than being assumed part of this purchase.
Yes, the Cisco SG220-50 has a 440 mm-wide, 44 mm-high rack-mount chassis, and a mounting kit is included. Chassis depth is 201 mm and weight is 3.3 kg. Check usable rack clearance and cable access before ordering, and specify the mounting hardware required with the selected condition.
SG220-50-K9-EU uses an internal 100-240V AC power supply rather than an external DC adapter. The fixed internal power arrangement does not provide a second redundant PSU bay. Confirm the regional power cord on the purchase order, and allow for the switch's 39.9W consumption at 220V when planning electrical loading.
SG220-50-K9-EU provides 100 Gbps switching capacity and 74.4 Mpps forwarding with 64-byte packets. These figures describe different traffic characteristics, so switching bandwidth should not be substituted for packet throughput during sizing. The switch also has a 12 Mb buffer shared dynamically across ports for packet buffering.
