SG220-50P-K9-EU combines 48 Gigabit Ethernet PoE+ access ports with Layer 2 smart switching in a 1U rack-mount chassis. Two fixed Gigabit combo uplink positions accept copper RJ-45 or fiber SFP connections; each position activates only one interface at a time. The Cisco 220 Series addresses small-business connectivity for workstations, IP phones, wireless access points, and cameras, including endpoints receiving electricity through their network cable. The discontinued SG220-50-K9-EU omits PoE, so substituting that sibling changes the endpoint power arrangement. Automatic voice VLAN handling assigns voice traffic its VLAN and QoS treatment, while guest VLANs separate visitor connectivity from business services. This Gigabit PoE+ smart switch provides powered copper access with fixed uplinks rather than a removable uplink card.

100 Gbps switching capacity defines the aggregate switching bandwidth available to connected devices. 74.4 Mpps forwarding at 64-byte packets provides a packet-rate reference for evaluating traffic requirements. 375W of shared PoE budget requires allocation across attached endpoints rather than treating each powered socket as an independent power supply. SG220-50P-K9-EU contains 128 MB of memory and 32 MB of flash for device operation and firmware storage. An 8192-entry MAC table accommodates learned addresses, while 12 Mb of dynamically shared packet buffering serves queues across the ports. STP/RSTP/MSTP provide loop control, and LACP supports link aggregation; dynamic routing is absent. HTTP/HTTPS browser access handles configuration and monitoring, while SNMPv3 supports secured management communication. IGMP snooping supports 256 multicast groups and directs multicast traffic toward requesting receivers. Eight hardware queues per port provide separate scheduling resources for traffic priorities, with strict-priority and weighted round-robin scheduling available for queue treatment.
SG220-50P-K9-EU is available new sealed or certified refurbished, with ORM extended coverage of up to three years for new units and up to one year for refurbished units; 30-day returns apply to every condition, terms apply. Certified refurbished units are inspected and bench-tested for PoE output under load on every powered port, every port linking at rated speed, optics recognition, PSU and fan status, POST, and clean boot; firmware is verified and configuration wiped to factory default. Specify condition, quantity, and regional power-cord requirements on the PO. ORM accepts POs, offers Net-30 for government, and provides RMA with advance replacement, with regional stock/RMA coverage in the UK, EU, US, and MEA for enterprise and volume orders.

When a rollout requires the same approved configuration across several offices, text-editable configuration files allow preparation before loading another unit. CLI privilege levels 1 and 15 distinguish operator access during staging. Specify the required configuration baseline, administrator access, and acceptance checks on the purchase order.
When phones, wireless access points, or cameras need power only during scheduled operating periods, time-based PoE can turn endpoint power on or off according to a defined schedule. SG220-50P-K9-EU provides that scheduling control. Confirm which endpoints must remain powered continuously and specify the intended schedule before purchase.
When a replacement unit must pass software acceptance before installation, two stored firmware images provide a fallback image for upgrade or downgrade work. A mirror configuration file preserves the latest stable configuration. Define the approved firmware, test sequence, and configuration baseline before including staged units on the purchase order.
10G uplinks to distribution
SG220-50P-K9-EU limits uplinks to 1GbE. CBS220-48P-4X-EU provides four 10G SFP+ uplinks while retaining 48 Gigabit PoE+ access ports; specify compatible uplink optics separately.
Endpoint power above 30W per port
SG220-50P-K9-EU limits power delivery to 30W per port. Endpoints requiring more than 30W from a single Ethernet connection exceed the PoE+ per-port limit.

SG220-50P-K9-EU identifies a Gigabit 220 Series smart switch: SG220 is the model family, 50 counts 48 access ports plus two combo uplinks, P denotes PoE+, and EU is the country/region suffix. K9 remains part of the complete ordering identifier; the powered ports share a 375W budget.
SG220-50P-K9-EU is managed through an HTTP/HTTPS web interface, a scriptable CLI over SSH or Telnet, SNMP, and Cisco FindIT Network Manager. Cisco FindIT Network Discovery Utility identifies devices, while FindIT Network Manager and Probe provide network administration. SNMP versions 1, 2c, and 3 are supported.
SG220-50P-K9-EU is discontinued: end of sale was July 30, 2022, software maintenance ended July 30, 2023, and applicable Cisco support ends July 31, 2027. CBS220-48P-4G-EU is the current replacement. Consider the remaining support period when purchasing legacy spares or planning a longer hardware replacement cycle.
SG220-50P-K9-EU is offered new sealed or certified refurbished. Cisco's limited lifetime hardware warranty is bounded by July 31, 2027; fans and power supplies have one-year coverage. ORM's new-unit extended warranty is up to three years; refurbished coverage is up to one year. All conditions have 30-day returns, terms apply.
SG220-50P-K9-EU replaces SG200-50FP-EU, which reached end of sale on October 4, 2018. The older model is discontinued. Keep both identifiers in the asset record when updating legacy purchase orders. SG220-50P-K9-EU is also discontinued, and CBS220-48P-4G-EU is the current continuation of this replacement chain.
SG220-50P-K9-EU provides a shared 375W PoE budget across 48 powered access ports, with a 30W maximum per port. The total budget does not support every powered port drawing its maximum simultaneously. Add the required power of all attached endpoints before specifying the final endpoint population.
Cisco 220 Series combo uplinks support MGBSX1 for Gigabit multimode fiber connections to 550m and MGBLX1 for Gigabit single-mode fiber connections to 10km. Each combo position shares its SFP slot with a copper interface, so select one connection medium for each position and match the remote optical interface.
SG220-50P-K9-EU supplies PoE+ to its access ports, whereas SG220-50-K9-EU supplies no endpoint power. Both models are discontinued. The powered model suits legacy installations delivering electricity over network cables; the non-PoE sibling matches endpoints with separate power. Preserve that distinction when selecting exact-match replacement stock.
SG220-50P-K9-EU has 48 access ports, whereas SG220-28MP-K9-EU has 24 access ports. Both models are discontinued. The larger model matches denser legacy copper connections; the smaller variant matches lower endpoint counts. Confirm the required access-port population before substituting either model on an existing purchase order.
CBS220-48P-4G-EU provides four dedicated Gigabit SFP uplinks, whereas SG220-50P-K9-EU provides two shared copper/SFP combo uplinks. CBS220-48P-4G-EU suits buyers moving to current replacement hardware; the discontinued SG220-50P-K9-EU suits exact-match legacy sparing. Specify uplink media before comparing quantities, because each combo position activates only one connection at a time.
Yes, SG220-50P-K9-EU has a 440 mm-wide, 44 mm-high rack-mount chassis and includes a mounting kit. The chassis depth is 350 mm and weight is 5.28 kg. Check cabinet clearance, cable routing, and rack support before ordering, particularly when replacing a shallower switch already installed in the cabinet.
The Cisco 220 Series SG220-50P model uses an internal AC power supply accepting 100-240V at 50-60 Hz. Maximum listed consumption including PoE is 427W. The supply is not a redundant modular arrangement. Confirm the installation's AC feed and regional power-cord requirement before completing the purchase order.
