SG550X-24MPP-K9-EU is a managed Layer 2+ access switch with 24 Gigabit Ethernet PoE+ ports and four fixed 10G uplinks for small and medium businesses. Two uplinks are dedicated SFP+ cages; the other two offer 10GBASE-T copper or SFP+ fiber, with one medium active per combo interface. The 1U chassis belongs to the Cisco 550X Series Stackable Managed Switches and connects powered phones, wireless access points, and surveillance cameras at the access edge. Unlike the discontinued SG550X-24MP-K9-EU, whose PoE allocation is 382W, this variant accommodates a larger aggregate endpoint power allocation. Automatic voice VLAN assignment separates phone traffic and applies voice-specific quality of service, while LLDP-MED exchanges endpoint information with attached IP phones.

128 Gbps switching capacity supports nonblocking forwarding across the fixed interfaces, while 95.23 Mpps specifies packet forwarding with 64-byte packets. 740W of shared PoE power defines the aggregate endpoint allocation, so individual port capability does not remove the need to size the combined load. Static routing and RIP v2 provide IP forwarding; VRRP supplies gateway redundancy, and PBR selects a next hop using access-control matches. SG550X-24MPP-K9-EU carries 512 MB of memory and 256 MB of flash for its control software and image storage. A dynamically shared 1.5 MB packet buffer handles traffic across the switch rather than assigning a fixed buffer to each port. The SG550X-24MPP supports 16000 MAC addresses, 7168 IPv4 routes, and 256 IP interfaces for sizing local addressing and routing requirements. STP, RSTP, MSTP, and LACP cover loop control and aggregated links. No dedicated out-of-band Ethernet management port is provided.
ORM Systems offers SG550X-24MPP-K9-EU new sealed or certified refurbished; refurbished units are inspected and bench-tested, powered ports are verified under load, and firmware is verified before configuration is wiped to factory default. Specify condition and accessories on the PO; new units carry up to 3-year extended warranty, certified refurbished units carry up to 1 year, and both have 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty is eligibility-dependent and ends no later than July 31, 2027. For enterprise and volume orders, ORM accepts POs and offers Net-30 for government, RMA with advance replacement, and regional stock/RMA in the UK, EU, US, and MEA.

When an endpoint rollout mixes standard PoE+ devices with higher-draw equipment, eight ports can supply 60W while the remaining powered ports are limited to 30W each. Allocate power by endpoint requirement rather than treating every port identically, and confirm the combined load before the PO.
When extending an existing hardware stack, the 550X family supports ring or chain connections and link aggregation for stack interconnects. Map those links against interfaces already assigned to upstream connections, then specify the topology and physical interconnect media before ordering additional members.
When preparing replacement hardware in a lab, dual firmware images allow an alternate image to remain available during software changes. USB file and image handling provides a local transfer path alongside network-based upgrades. Specify the required firmware image, saved configuration, and recovery procedure before releasing the order for staging.
Four independent copper uplink connections
Only two uplinks provide 10GBASE-T, and each shares its logical interface with an SFP+ cage. The remaining two uplinks are dedicated SFP+ interfaces.
Dual internal redundant power supplies
Power redundancy depends on an external redundant power system rather than a second internal supply. Dual internal hot-swappable PSU bays are not part of this chassis.
New Cisco software maintenance releases
Software maintenance ended July 30, 2023. C1300-24FP-4X is the current migration endpoint through the discontinued CBS350-24FP-4X-EU, rather than a continuation of 550X software maintenance.

SG550X-24MPP-K9-EU is the EU-region ordering form of the SG550X-24MPP: SG550X identifies the Gigabit stackable managed family, 24 denotes the access-port count, and MPP distinguishes the 740W PoE+ configuration. K9 is retained in the complete ordering identifier. EU covers the European Union and several additional regional markets.
The Cisco 550X Series supports browser management over HTTP/HTTPS, Textview CLI through console or SSH, SNMP, Smart Network Application, FindIT Network Manager with its embedded Probe, and Active Advisor. Cisco Network Plug and Play also supports provisioning. Select the intended administration and automation paths before commissioning the switch.
SG550X-24MPP-K9-EU reached end of sale on July 30, 2022, and its last date of support is July 31, 2027. Software maintenance ended July 30, 2023. The original replacement, CBS350-24FP-4X-EU, is also discontinued; the forward migration now ends at C1300-24FP-4X.
ORM Systems offers SG550X-24MPP-K9-EU new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions have 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is subject to eligibility and ends no later than July 31, 2027.
SG550X-24MPP-K9-EU provides a shared 740W PoE budget across 24 powered ports, with eight supporting 60W and the other sixteen supporting 30W per port. The individual maxima exceed the total budget when combined, so allocate power to the actual endpoint mix instead of assuming every port can operate at its maximum simultaneously.
SG550X-24MPP-K9-EU has four fixed 10G uplinks: two dedicated SFP+ interfaces and two shared 10GBASE-T/SFP+ combo interfaces. Only one medium can operate on each combo interface at a time. SFP-10G-SR supports multimode fiber; SFP-10G-LR supports single-mode fiber. Specify the required transceivers separately from the chassis.
Yes, SG550X-24MPP-K9-EU supports true hardware stacking with eight members using 10G copper or fiber connections, including ring and chain topologies. Supported direct-attach cable choices include SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M. Stack interconnects use network interfaces, so reserve those interfaces when planning upstream connectivity.
SG550X-24MPP-K9-EU supports static routing, RIP v2, VRRP, and PBR, with 7168 IPv4 routes and 256 IP interfaces. IPv6 static routing supports 1792 routes and 256 IPv6 interfaces. Match the required routing behavior and address scale before using the switch as an inter-VLAN gateway.
SG550X-24MPP-K9-EU is a rack-mount 1U switch measuring 440 mm wide, 44 mm high, and 450 mm deep, with a weight of 6.19 kg. The operating range is 0°C to 50°C. The mounting kit is included with the original package; confirm accessory contents for the selected condition.
SG550X-24MPP-K9-EU has one internal AC supply and supports an external redundant-power connection, rather than dual internal PSU bays. The input range is 100-240V AC, and maximum draw is 870.1W. Electrical-feed sizing must include switch overhead rather than treating the PoE allocation as the total input load.
SG550X-24MPP-K9-EU supplies 740W of PoE power, while SG550X-24MP-K9-EU provides 382W across the same number of powered access ports. Both models are discontinued. The MPP model matches an existing configuration with greater endpoint power allocation; the MP model matches a lower-power legacy configuration.
SG550X-48MP-K9-EU offers 48 Gigabit PoE+ access ports, while SG550X-24MPP-K9-EU offers 24, so the difference is connection density. Both are discontinued members of the same family. Existing sites requiring more endpoint connections use the 48-port layout; sites retaining a smaller access footprint use the 24-port layout.
C1300-24FP-4X has four 10G SFP+ uplinks, while SG550X-24MPP-K9-EU combines two dedicated SFP+ uplinks with two copper/SFP+ combo uplinks. C1300-24FP-4X is the current migration endpoint after the discontinued CBS350-24FP-4X-EU. The newer model suits replacement purchases; the older model retains copper-uplink options for an existing installation.
