SG550X-24MPP-K9-NA combines 24 Gigabit PoE+ access ports with four fixed 10G uplinks in a managed Layer 2+ access switch. Two uplinks are dedicated SFP+ interfaces; two are 10GBASE-T/SFP+ combo interfaces, with either copper or fiber active on each shared connection. The 1U chassis belongs to the Cisco 550X Series and connects powered endpoints to a small-business network without requiring an uplink expansion card. Wireless access points, video phones and surveillance cameras can share the powered access interfaces. The discontinued SG550X-24MP-K9-NA carries a smaller 382W endpoint power budget. This 24-port Gigabit PoE+ access switch retains copper uplink connectivity where fiber is unnecessary, while its dedicated optical interfaces accommodate fiber connections to aggregation equipment.

128 Gbps switching capacity accommodates the access and uplink interfaces, while 95.23 Mpps forwarding handles minimum-sized packets. 740W of shared PoE allocation governs simultaneous endpoint demand rather than guaranteeing every port's maximum output together. Static IPv4/IPv6 routing and RIP v2 support communication between local subnets; PBR controls next-hop selection, and VRRP provides default-gateway redundancy. SG550X-24MPP-K9-NA uses 512 MB of memory for switch operation and 256 MB of flash for software storage, with a dynamically shared 1.5 MB packet buffer absorbing traffic bursts. The forwarding resources accommodate 16000 MAC entries and 7168 IPv4 routes. STP/RSTP/MSTP handle bridged topology control, while LACP groups links for aggregated connections. Browser management and Textview CLI provide local configuration paths, with SNMP available for monitoring. 870.1W maximum consumption at 110V supplies an electrical sizing reference for a fully powered installation. Internal hot-swappable power supply redundancy is absent; power redundancy instead requires an external system.
ORM Systems offers SG550X-24MPP-K9-NA 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. New units carry up to a 3-year extended ORM warranty, certified refurbished units up to 1 year, and every condition includes 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is subject to eligibility, with Cisco service ending July 31, 2027. Specify condition, quantity and required accessories on the purchase order; PO acceptance, Net-30 for government, RMA with advance replacement, and UK, EU, US and MEA regional stock/RMA support enterprise and volume orders.

When a refresh includes higher-draw wireless access points or connected lighting, eight designated interfaces support 60W PoE while the remaining powered interfaces support 30W. Endpoint compatibility and simultaneous demand determine the port assignment; specify the power requirement of each connected device before issuing the PO.
When an existing stack mixes access and aggregation hardware, the 550X family permits SF550X, SG550X, SG550XG and SX550X members in the same system. Ring and chain arrangements are supported. Confirm existing member identities and the planned topology before specifying the additional switch and its interconnections.
For a repeatable branch rollout, SG550X-24MPP-K9-NA supports Cisco Network Plug and Play with Cisco PnP Connect, plus configuration deployment through secure file transfer. A staging plan can use a common configuration and device discovery workflow; specify provisioning credentials and the approved configuration before releasing the hardware PO.
Multigigabit speeds across access ports
The access interfaces stop at Gigabit Ethernet. The 10G connectors provide uplinks rather than multigigabit copper connectivity across the powered endpoint ports.
More than eight stacked switches
Hardware stacking is limited to eight switches in one system. A design requiring additional members cannot operate as a single 550X hardware stack.
Ongoing software maintenance for new deployments
Software maintenance ended July 30, 2023. C1300-24FP-4X is the current migration target, following the discontinued intermediate replacement CBS350-24FP-4X-NA.

SG550X-24MPP-K9-NA identifies a 550X Gigabit managed switch with 24 PoE+ access ports and a 740W power allocation. SG550X identifies the model family, 24 gives the access-port count, MPP distinguishes this power-budget variant, and NA identifies the Americas ordering region, including the United States and Canada.
SG550X-24MPP-K9-NA is managed through an HTTP/HTTPS web interface, Textview CLI over console, SSH or Telnet, and SNMP. Network-level tools include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, and Active Advisor. Cisco Network Plug and Play with Cisco PnP Connect supports provisioning.
SG550X-24MPP-K9-NA is discontinued: end of sale was July 30, 2022, and the last date of Cisco support is July 31, 2027. Software maintenance ended July 30, 2023. Its direct replacement, CBS350-24FP-4X-NA, is also discontinued; the current migration target is C1300-24FP-4X.
SG550X-24MPP-K9-NA is offered 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. Both carry 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty remains subject to eligibility and ends with Cisco support on July 31, 2027.
SG550X-24MPP-K9-NA supports 60W PoE on eight designated access ports, while the other powered access ports support 30W maximum. All powered ports share the 740W allocation. The higher per-port capability does not permit every interface to draw its individual maximum simultaneously, so endpoint compatibility and concurrent demand must be checked.
The Cisco 550X Gigabit PoE+ switch has four 10G uplinks: two dedicated SFP+ interfaces and two 10GBASE-T/SFP+ combo interfaces. Each combo connection activates either copper or fiber, not both. SFP-10G-SR supports multimode fiber links, while SFP-10G-LR supports single-mode fiber links; specify the required transceivers separately.
The 550X Series stacks eight members through 10G copper or fiber connections and supports ring or chain arrangements. Hybrid stacks can combine SF550X, SG550X, SG550XG and SX550X models. Copper interconnect options include SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M; reserve the necessary interfaces before assigning the remaining connections to uplinks.
SG550X-24MPP-K9-NA provides a 740W PoE budget, while SG550X-24MP-K9-NA provides 382W. Both carry 24 Gigabit PoE+ access ports. Both models are discontinued. The higher-budget model accommodates a larger aggregate endpoint power requirement; the lower-budget model serves an existing hardware requirement where the smaller shared allocation is sufficient.
SG550X-24MPP-K9-NA has 24 Gigabit access ports, whereas SG550X-48MP-K9-NA has 48. Both models are discontinued. The smaller model serves a requirement for fewer endpoint connections; the larger model accommodates more copper endpoints in one chassis. Specify the required access-port count before selecting either discontinued model for an existing installation.
SG550X-24MPP-K9-NA is discontinued, while C1300-24FP-4X is the current migration target through the discontinued intermediate replacement CBS350-24FP-4X-NA. The older switch serves existing 550X hardware requirements. C1300-24FP-4X is the successor to specify when purchasing the current replacement rather than maintaining the earlier model, whose Cisco support ends July 31, 2027.
