SG550X-24MP-K9-UK combines 24 Gigabit Ethernet PoE+ access ports with fixed 10G uplinks and selected higher-power outputs for connected endpoints. The managed Layer 2+ switch belongs to the Cisco 550X Series and occupies one rack unit, serving small-business networks connecting phones, wireless access points, and surveillance cameras. Two uplinks provide dedicated SFP+ connections; two additional connections offer shared 10GBASE-T/SFP+ interfaces, with one medium active on each combo connection. Copper and optical uplink choices are built into the chassis rather than added through a removable network card. The discontinued SG550X-24P-K9-UK is the lower-budget sibling, carrying 195W for aggregate endpoint power. Automatic voice VLAN assignment separates phone traffic and applies its configured QoS treatment.

128 Gbps switching capacity and 95.23 Mpps forwarding for 64-byte packets establish the traffic-handling limits. 382W of shared PoE power covers the connected endpoint load; eight powered ports support 60W, while the other powered ports support 30W until the aggregate budget is reached. Static routing, RIP v2, PBR, and VRRP provide subnet forwarding, policy-based next-hop selection, and default-gateway redundancy. SG550X-24MP-K9-UK has 512 MB of DRAM and 256 MB of flash for system operation and image storage, while a dynamically shared 1.5 MB packet buffer serves all ports. The MAC table accommodates 16000 entries, and IPv4 routing supports 7168 routes. The 550X Series Stackable Managed Switches offer browser configuration over HTTP/HTTPS and a scriptable CLI, with SNMPv3 available for monitoring. STP, RSTP, MSTP, and LACP handle loop control and link grouping. Cooling uses three operating fans and one redundant fan, with fan speed adjusted to switch temperature.
Specify SG550X-24MP-K9-UK as new sealed or certified refurbished, with condition, quantity, and connection accessories itemized on the PO. Certified refurbished units are inspected and bench-tested, including PoE output under load on every powered port, firmware verification, and configuration wiped to factory default. ORM warranties provide up to a 3-year extended term for new units and up to 1 year for certified refurbished units; every condition includes 30-day returns, terms apply, while Cisco's limited lifetime hardware coverage ends July 31, 2027.

When a branch refresh must keep inter-VLAN routing on the access switch, the routing design can use 256 IPv4 interfaces and 1792 IPv6 static routes. Physical ports, VLAN interfaces, link aggregation groups, and loopback interfaces support routed configuration. Confirm interface requirements and address plans before specifying quantities.
When an existing hardware stack needs another member, ring or chain connections can use copper or fiber interconnects, including SFP-H10GB-CU1M for a 1 m direct-attach connection. Link aggregation can also serve the stack interconnect. Check occupied connections, cable reach, and the planned topology before adding the unit to the PO.
When several sites need the same baseline configuration, text-editable configuration files and SCP autoconfiguration support staging from a shared file set. Dual firmware images support image preparation before shipment. Define site-specific addressing, configuration file delivery, and the accepted firmware baseline before placing a batch order for the individual sites.
Faster-than-Gigabit copper access connections
The access interfaces stop at 1GbE; 10GbE connectivity is confined to the uplinks. Specify a different switch when endpoint connections require faster native copper access.
Silent fanless equipment operation
The chassis uses three operating fans and one redundant fan, rather than passive cooling. A fanless switch is required where the purchasing specification prohibits fan noise.

SG550X-24MP-K9-UK identifies a 550X Gigabit stackable switch: 24 denotes the access-port count, MP selects the 382W PoE+ configuration, and UK selects the United Kingdom regional ordering group. K9 remains part of the complete ordering identifier. That regional group also includes Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia.
The Cisco 550X supports browser management over HTTP/HTTPS, console or SSH/Telnet CLI access, SNMP, and Smart Network Application. Network-management integrations include FindIT Network Manager, an embedded FindIT Network Probe, and Active Advisor. The local interface provides simple and advanced modes, while the CLI supports scripting and menu-based operation.
SG550X-24MP-K9-UK reached end of sale on July 30, 2022; software maintenance ended July 30, 2023, and the last date of support is July 31, 2027. The switch is discontinued. Its intermediate CBS350-24FP-4X-UK replacement is also discontinued, with C1300-24FP-4X now the current successor at the end of the replacement chain.
ORM Systems offers SG550X-24MP-K9-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty; both include 30-day returns, terms apply. Cisco's limited lifetime hardware warranty is bounded by July 31, 2027, the last date of support. Refurbished units are inspected and bench-tested.
SG550X-24MP-K9-UK replaces the discontinued SF550X-24MP-K9-UK, a 24-port 10/100 PoE stackable switch whose end-of-sale date was June 18, 2020. The replacement moves access connections to Gigabit Ethernet while retaining 24 powered access ports. Confirm endpoint power requirements and uplink media before finalizing replacement quantities and connection accessories.
SG550X-24MP-K9-UK provides a shared 382W PoE budget across 24 powered ports, including eight ports supporting 60W; the remaining powered ports support 30W. The aggregate budget does not permit every port to draw its individual maximum simultaneously. Size the connected endpoint allocation against the shared budget before ordering.
SG550X-24MP-K9-UK has four fixed 10G uplinks: two dedicated SFP+ connections and two 10GBASE-T/SFP+ combo connections. Each combo connection permits one active medium at a time. Compatible optical options include SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber, ordered separately; no removable uplink card is required.
The Cisco 550X hardware stack supports eight members using 10G copper or fiber connections in ring or chain topologies. Direct-attach cable options include SFP-H10GB-CU1M at 1 m, SFP-H10GB-CU3M at 3 m, and SFP-H10GB-CU5M at 5 m. A stack uses single-IP management, and link aggregation can carry stack interconnect traffic.
SG550X-24MP-K9-UK supports static routing and RIP v2, with PBR for next-hop policy and VRRP for gateway redundancy. The switch supports 7168 IPv4 routes, 1792 IPv6 static routes, and 256 IPv4 interfaces. Confirm route counts, interface requirements, and the required routing protocol before assigning inter-VLAN forwarding to this switch.
SG550X-24MP-K9-UK is a 1U rack-mount switch measuring 440 mm wide, 44 mm high, and 350 mm deep, with a weight of 5.33 kg. The standard package includes a mounting kit. Allow for powered cooling and verify that the installation remains within the 0°C to 50°C operating range.
SG550X-24MP-K9-UK uses an internal AC supply rather than a pair of internal redundant PSU modules; power redundancy uses an external redundant power system. Input is 100-240V AC. Worst-case consumption with PoE is 471.2W at 110V or 460.4W at 220V, which must be included in electrical load planning.
SG550X-24MP-K9-UK provides a 382W PoE budget, while SG550X-24P-K9-UK provides 195W. Both models are discontinued. Within existing 550X installations, the P configuration fits lower aggregate powered-device loads, while the MP configuration accommodates a larger combined endpoint allocation. Neither budget should be interpreted as simultaneous maximum output from every powered port.
SG550X-24MP-K9-UK has 24 Gigabit access ports, whereas SG550X-48P-K9-UK has 48 Gigabit access ports. Both models are discontinued. For an existing 550X installation, the 24-port unit fits a smaller connection requirement; the 48-port unit serves a higher endpoint count without adding another access-switch chassis to the rack.
C1300-24FP-4X has four 10G SFP+ uplinks, while SG550X-24MP-K9-UK has two dedicated SFP+ connections plus two 10G copper/SFP+ combo uplinks. The original switch is discontinued, and C1300-24FP-4X is its current successor after the discontinued CBS350-24FP-4X-UK. Existing copper-uplink replacement requirements favor the original configuration; new successor orders point to C1300-24FP-4X.
