SG550X-24MPP-K9 combines 24 Gigabit PoE+ access ports with four fixed 10G uplinks in a managed, 1U rack-mount switch for small and medium businesses. Two uplinks are dedicated SFP+ slots; the other two are combo connections offering either 10GBASE-T copper or SFP+ fiber, with one medium active per connection. The Cisco 550X Series supports powered wireless access points, IP phones and surveillance cameras alongside conventional Ethernet clients. Layer 2+ functionality includes inter-VLAN communication without requiring a separate router for every internal subnet. Compared with the discontinued SG550X-24MP-K9-NA, this model raises the endpoint-power allocation from 382W to 740W. Cisco SG550X-24MPP also supports voice VLAN assignment and traffic prioritization for connected phones, keeping endpoint segmentation and forwarding policies within the managed switch configuration.
SG550X-24MPP-K9 price for new stock is $1,674.75, a 45.5% saving from the Cisco list price of $3,072.91. SG550X-24MPP-K9 refurb price is $1,388.63. SG550X-24MPP-K9 is in stock and available for next-day dispatch. (terms applied)

128 Gbps switching capacity covers the access and uplink interfaces. 95.23 Mpps forwarding at 64-byte packet size provides the small-packet throughput figure for traffic planning. Static routing and RIP v2 handle subnet reachability; PBR controls next-hop selection, and VRRP provides default-gateway redundancy. SG550X-24MPP-K9 carries 512 MB of memory and 256 MB of flash for embedded software and configuration handling. Its 1.5 MB packet buffer is shared dynamically across ports rather than reserved separately for each interface. STP/RSTP/MSTP and LACP support loop control and aggregated links, while DHCP snooping and Dynamic ARP Inspection enforce address-binding checks. Administrators can use encrypted HTTPS and SSH sessions or integrate SNMPv3 monitoring. 870.1W worst-case consumption with PoE sets the AC load to consider when sizing UPS capacity and power circuits. Cooling uses four fans with one additional redundant fan; a second internal power supply is not available.
ORM Systems offers SG550X-24MPP-K9 new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified and configurations wiped to factory default. Specify the regional order suffix, condition, quantity and connectivity accessories on the PO. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, plus 30-day returns on every condition, terms apply; Cisco's separate limited lifetime coverage ends July 31, 2027. For enterprise and volume orders, POs are accepted, with Net-30 for government, RMA with advance replacement, and regional stock/RMA coverage across the UK, EU, US and MEA.

When an endpoint refresh includes higher-draw access points or connected lighting, eight powered connections can supply 60W per port; the remaining powered connections support 30W per port. Mixed endpoint loads still need an aggregate power plan, so specify device demand and the required high-power port allocation before the PO.
When separate workgroups need local communication across subnets, the switch supports 256 IP interfaces and can place routed interfaces on physical ports, link aggregations, VLAN interfaces or loopbacks. Map the intended interface layout against that ceiling, then specify the required interface configuration and upstream routing arrangement before ordering.
When replacement units must enter an established configuration workflow, dual software images allow an alternate image to remain available during upgrade preparation. Text-editable configuration files and secure file transfer support repeatable staging. Specify the approved firmware baseline and configuration acceptance checks before committing the replacement quantity to the PO.
Multigigabit speeds on endpoint ports
SG550X-24MPP-K9 limits fixed access connections to 1GbE. C1300-24MGP-4X provides eight 2.5GbE access ports and sixteen Gigabit access ports for mixed-speed endpoint requirements.
Cisco support beyond July 2027
SG550X-24MPP-K9 reaches its last date of Cisco support on July 31, 2027. C1300-24FP-4X is the current endpoint of its replacement chain.
Two internal redundant power supplies
SG550X-24MPP-K9 does not provide a second internal power-supply bay. Power redundancy uses an external redundant-power connection rather than two internal redundant supply modules.

SG550X-24MPP-K9 names a 24-port Gigabit PoE+ switch with a 740W budget. SG550X identifies the Gigabit 550X model range, 24 gives the access-port count, and MPP selects this power configuration. SG550X-24MPP-K9-NA adds the North American regional ordering suffix to the catalog number.
SG550X-24MPP-K9 provides a shared 740W PoE budget across 24 powered access ports, including eight ports supporting 60W each. The remaining powered ports support 30W each. Simultaneous endpoint allocations must stay within the aggregate budget; the individual port ceilings do not guarantee every port can reach its maximum together.
SG550X-24MPP-K9 includes four fixed 10G uplinks: two dedicated SFP+ connections and two 10GBASE-T/SFP+ combo connections. Each combo connection uses either its copper interface or its SFP+ interface, not both simultaneously. The copper and SFP+ uplink interfaces also support 1G operation when configured with compatible connectivity.
SG550X-24MPP-K9 is managed through HTTP/HTTPS web access, Textview CLI over console, SSH or Telnet, and SNMP v1/v2c/v3. Network-level options include Smart Network Application, FindIT Network Manager, the embedded FindIT Network Probe and Active Advisor. Network Plug and Play supports provisioning, while USB handles local image and configuration transfers.
Cisco 550X hardware stacking supports eight switches as one managed system, using 10G copper or fiber interconnects in ring or chain arrangements. SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M provide supported direct-attach connections. Interconnects consume uplink capacity, so reserve the required connections before assigning network uplinks.
SG550X-24MPP-K9 supports static routing, RIP v2, PBR and VRRP, with an IPv4 capacity of 7168 routes and 256 IP interfaces. IPv6 static routing supports 1792 routes. Routed interfaces can use physical ports, link aggregations, VLAN interfaces or loopbacks, allowing internal subnet communication within the switch.
No, SG550X-24MPP-K9 does not use two internal redundant power supplies; redundancy relies on an external redundant-power connection. The normal power input is an internal universal AC supply. A purchase requiring independently replaceable internal supply modules therefore needs a different power architecture rather than an additional internal module.
SG550X-24MPP-K9 occupies 1U and measures 440 mm wide, 44 mm high and 450 mm deep, with a weight of 6.19 kg. Allow additional space for power and network cabling beyond the chassis depth. The original switch package includes mounting hardware, a power cord and a console cable.
SG550X-24MPP-K9 reached end of sale on July 30, 2022, and its last date of Cisco support is July 31, 2027. Software maintenance ended July 30, 2023. Eligible hardware service can continue until the support deadline, but that remaining service window does not restart software maintenance.
ORM Systems offers SG550X-24MPP-K9 new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Every condition has 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty ends July 31, 2027, subject to the unit's warranty entitlement.
SG550X-24MPP-K9 provides a 740W PoE budget, while SG550X-24MP-K9-NA provides 382W. Both models are discontinued, so the comparison concerns matching existing installations rather than selecting a current successor. The MPP configuration addresses larger aggregate endpoint demand; the MP configuration matches installations built around the smaller power allocation.
SG550X-24MPP-K9 has 24 Gigabit access ports, whereas SG550X-48MP-K9-NA has 48. Both models are discontinued. The smaller configuration matches existing installations requiring fewer access connections; the larger configuration matches higher-density installations. Count the required endpoint connections before choosing which chassis configuration an installed-base spare must match.
C1300-24FP-4X has four 10G SFP+ uplinks, while SG550X-24MPP-K9 has two dedicated SFP+ uplinks and two copper/SFP+ combo uplinks. C1300-24FP-4X is the current endpoint of the replacement chain through discontinued CBS350-24FP-4X-NA. Existing copper-uplink installations need the combo arrangement; replacement designs using four fiber uplinks align with the current model.
