SG550X-24MPP-K9-UK provides 24 Gigabit Ethernet PoE+ access ports and four fixed 10G uplinks in a managed Layer 2+ switch for small and medium business networks. Two uplink positions combine 10GBASE-T copper with SFP+ connectivity, while two are dedicated SFP+ slots; each combo pair permits one active medium. The 1U rack chassis belongs to the Cisco 550X Series Stackable Managed Switches family and connects powered phones, wireless access points, and video equipment. The discontinued SG550X-24MP-K9-UK is its lower-budget PoE sibling. This 24-port Gigabit PoE+ access switch provides its uplink interfaces without a removable port-expansion card, so procurement centers on the required connection media rather than a separate uplink module.

128 Gbps switching capacity supports nonblocking traffic across the installed interfaces. 95.23 Mpps forwarding covers 64-byte packets, providing the packet-rate figure for workloads dominated by small frames. 740W of shared PoE capacity limits aggregate endpoint power allocation regardless of individual port ceilings. RIP v2 supplies dynamic routing alongside IPv4 static routing, IPv6 static routing, PBR, and VRRP versions 2 and 3. The forwarding resources accommodate 7168 IPv4 routes and 16000 MAC entries, keeping routing scale distinct from address-learning capacity. SG550X-24MPP-K9-UK carries 512 MB of DRAM and 256 MB of flash for its operating software and stored configuration. An aggregate 1.5 MB packet buffer is dynamically shared across ports rather than reserved equally for each connection. STP, RSTP, and MSTP control Layer 2 topology, while LACP supports link aggregation. Traffic classification includes eight hardware queues, with strict-priority and weighted round-robin scheduling available for differentiated treatment.
ORM offers SG550X-24MPP-K9-UK new sealed or certified refurbished, with 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. Refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port and firmware verified before configuration is wiped to factory default. Specify condition, quantity, and connection accessories on the PO; Cisco's separate limited lifetime hardware warranty ends with support on July 31, 2027. Enterprise and volume purchasing includes PO acceptance, Net-30 for government, and RMA with advance replacement, supported by UK, EU, US, and MEA stock and RMA coverage.

Sites adding higher-draw powered endpoints can use eight ports that support 60W PoE, while the other access ports support 30W each. Endpoint compatibility and simultaneous demand must be checked against the shared allocation before the PO; specify which devices require the higher-power ports.
Organizations standardizing regional spares need to match the -UK ordering variant to the intended destination. This regional form covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia. Keep the regional part number in the bill of materials and confirm the destination power connection before the PO.
Teams staging replacement units can use the front-panel USB Type-A slot for image and configuration transfer. Text-editable configuration files and Secure Copy provide additional preparation paths. Establish the approved image and configuration for each batch, then state the required staging baseline before the PO.
2.5G connections on access ports
The 24 access ports operate at Gigabit Ethernet speed, not 2.5G. Faster uplink connections do not change the speed available on those access ports.
Fanless operation in occupied rooms
The chassis uses four fans plus one redundant fan, with acoustic noise reaching 53.2 dB at 50°C. A fanless installation requirement excludes this model.
Cisco support beyond July 2027
Cisco service ends July 31, 2027, for this discontinued switch. C1300-24FP-4X is the current migration endpoint after the also-discontinued CBS350-24FP-4X-UK replacement.

SG550X-24MPP-K9-UK identifies the Gigabit 550X family, 24 PoE+ access ports, the MPP configuration with a 740W budget, and the -UK regional variant. The -UK suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia; retain the complete K9-bearing identifier on the PO.
The Cisco 550X is managed through HTTP/HTTPS, Textview CLI over console, SSH or Telnet, SNMP 1/2c/3, Smart Network Application, FindIT Network Manager with its embedded Probe, and Active Advisor. FindIT Network Discovery provides device discovery, while the Network Plug and Play agent supports provisioning. Simple and advanced web modes provide configuration and monitoring.
SG550X-24MPP-K9-UK provides 740W of shared PoE power across 24 access ports, with eight ports supporting 60W and the other ports supporting 30W. Power allocation stops at the aggregate budget, so higher per-port ceilings do not mean every endpoint can request its maximum simultaneously. Check endpoint compatibility and concurrent loads before assigning higher-power devices.
SG550X-24MPP-K9-UK has four logical 10G uplink ports: two dedicated SFP+ slots and two 10GBASE-T/SFP+ combo positions. Only one interface in each combo position can be active at once. The fixed uplinks support 1G and 10G speeds; choose copper or fiber media for the actual connection rather than a removable uplink card.
A Cisco 550X hardware stack connects eight members using standard 10G fiber or copper interfaces, with ring and chain layouts. SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M provide supported 1 m, 3 m, and 5 m copper options. Stack links share the 10G interface pool, so retain enough interfaces for connections outside the stack.
Yes, SG550X-24MPP-K9-UK supports static routing, RIP v2, PBR, and VRRP versions 2 and 3. Its IPv4 routing limit is 7168 routes with 256 IP interfaces; IPv6 static routing supports 1792 routes. Keep those separate limits in the migration plan rather than treating the IPv6 figure as additional IPv4 capacity.
No, SG550X-24MPP-K9-UK does not include two hot-swappable internal power supplies; the chassis uses an internal universal AC supply and provides an RPS connector. Input covers 100-240V AC at 47-63 Hz. The external redundant-power connection should not be confused with a second internal PSU bay when writing the purchase specification.
Yes, SG550X-24MPP-K9-UK ended Cisco sales on July 30, 2022, and its last date of support is July 31, 2027. Software maintenance ended July 30, 2023. Remaining reseller inventory does not reopen the Cisco sales window or extend vendor service eligibility; the support boundary continues to govern any applicable Cisco entitlement.
SG550X-24MPP-K9-UK provides a 740W PoE budget, whereas the discontinued SG550X-24MP-K9-UK provides 382W. Both retain 24 Gigabit PoE+ access ports and fixed 10G uplinks. The MPP model serves purchases requiring the larger power allocation; the MP model addresses replacement requirements where a lower aggregate budget matches the existing design.
SG550X-24MPP-K9-UK has 24 Gigabit PoE+ access ports, whereas the discontinued SG550X-48MP-K9-UK has 48. Both have a 740W PoE budget, so the additional ports do not bring a larger aggregate endpoint power allocation. The 24-port model serves a smaller connection count; the 48-port model addresses denser existing 550X installations.
SG550X-24MPP-K9-UK is discontinued, while C1300-24FP-4X is the current migration endpoint for the 24-port Gigabit Full PoE configuration. The first replacement, CBS350-24FP-4X-UK, also ended sales on October 29, 2024. Retaining 550X hardware may matter for existing estates; new purchases requiring a current product lifecycle should use C1300-24FP-4X.
SG550X-24MPP-K9-UK is available 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. Every condition includes 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty cannot extend beyond July 31, 2027.
