SG550X-24P-K9-NA provides 24 Gigabit PoE+ access ports and four fixed 10G uplinks in a managed, stackable switch for small-business networks. Two uplinks are dedicated SFP+ interfaces; the other two offer shared copper/SFP+ connections, with one medium active per combo interface. The 1U chassis belongs to the Cisco 550X Series and supports Layer 2+ operation with routing capabilities for communication between network segments. Powered connections accommodate IP phones, wireless access points, and surveillance cameras. The discontinued SG550X-24-K9-NA provides the same access-port density without PoE. Browser-based administration and Textview CLI access give the SG550X-24P both graphical and command-line configuration paths.

128 Gbps switching capacity and 95.23 Mpps forwarding support wire-speed operation, with the forwarding figure measured using 64-byte packets. A 195W shared PoE budget limits simultaneous endpoint power allocation; eight powered ports support 60W, while the remaining powered ports support 30W. SG550X-24P-K9-NA uses 512 MB of DRAM and 256 MB of flash, with a 1.5 MB packet buffer shared across its ports. Static routing and RIP v2 support inter-VLAN connectivity, while PBR controls next-hop selection and VRRP versions 2 and 3 provide gateway redundancy. The routing capacity accommodates 7168 IPv4 routes and 256 IP interfaces. STP, RSTP, MSTP, and LACP support loop control and aggregated connections. Four fans include one redundant fan. Power redundancy uses an external RPS2300 rather than a second internal power-supply module.
SG550X-24P-K9-NA is offered new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for certified refurbished units; every condition includes 30-day returns, terms apply. Refurbished units are inspected and bench-tested, including rated-speed port links, PoE output under load on every powered port, firmware verification, and configuration wiped to factory default. Specify condition, quantity, optics, and warranty on the purchase order; Cisco's separate limited lifetime hardware warranty is bounded by July 31, 2027. POs are accepted, government buyers can use Net-30, and volume requirements can include RMA with advance replacement through UK, EU, US, and MEA stock/RMA operations.

Replacement PID | C1300-24P-4X |
An installed SF550X-24P-K9-NA reaching replacement time creates a direct migration requirement: that discontinued model uses 10/100 access connections, and this switch was named as its replacement. Preserve the existing endpoint inventory, review configuration requirements, and specify the required powered connections and condition before issuing the purchase order.
An existing 550X hardware stack can combine SF550X, SG550X, SG550XG, and SX550X members rather than requiring identical access speeds throughout. Ring and chain arrangements use network interfaces for interconnection. Before ordering another member, check the existing topology, remaining interfaces, interconnect distances, and intended position within the stack.
A repeat branch rollout can use Cisco Network Plug and Play for provisioning and SCP configuration downloads for staged configuration delivery. Text-editable configuration files support reuse across switches. Before the purchase order, specify the staging configuration, provisioning method, management credentials, and image requirements for the units being ordered.
Maximum power on every port
The shared 195W budget cannot supply every powered port at its individual maximum simultaneously; endpoint demand must remain within the switch-wide allocation.
Cisco support beyond July 2027
Cisco support ends July 31, 2027. C1300-24P-4X is the current migration endpoint after the discontinued intermediate replacement, CBS350-24P-4X-NA.

SG550X-24P-K9-NA identifies a Gigabit 550X stackable switch with 24 PoE+ access ports. SG550X is the model family, 24P identifies the powered access configuration, and K9 remains part of the complete ordering identity. NA selects the regional form covering the United States, Canada, Mexico, and additional listed American markets.
SG550X-24P-K9-NA supports HTTP/HTTPS web management, Textview CLI through console, SSH or Telnet, and SNMP. Additional paths include Smart Network Application, FindIT Network Manager with the embedded FindIT Network Probe, FindIT Network Discovery Utility, and Active Advisor. Cisco Network Plug and Play supports automated provisioning rather than replacing local administration.
SG550X-24P-K9-NA provides a shared 195W PoE budget across 24 powered access ports. Eight ports support individual outputs of 60W, and the other powered ports support 30W. These individual ratings do not increase the shared budget, so endpoint demand must be allocated across the connected devices.
The Cisco 550X switch supports SFP-10G-SR and SFP-10G-SR-S for multimode fiber, plus SFP-10G-LR and SFP-10G-LR-S for single-mode fiber. The long-reach options support 10 km links. Select the exact optic against the installed fiber and required distance, and include the selected part number on the order.
Yes, SG550X-24P-K9-NA supports hardware stacking with eight members and permits mixed SF550X, SG550X, SG550XG, and SX550X stacks. Interconnects use 10G copper or fiber interfaces in ring or chain arrangements. Supported copper cable options include SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M; reserve the required interfaces when planning the stack.
The Cisco 550X switch provides static routing, RIP v2, PBR, and VRRP versions 2 and 3. Its IPv4 routing capacity reaches 7168 routes with 256 IP interfaces, while IPv6 static routing supports 1792 routes. Routing interfaces can use physical ports, aggregated links, VLAN interfaces, or loopback interfaces.
Yes, SG550X-24P-K9-NA reached end of sale on July 30, 2022, and its last date of support is July 31, 2027. Software maintenance releases ended July 30, 2023. Remaining reseller inventory does not change these milestones, so the intended service period should be checked before ordering.
SG550X-24P-K9-NA was named as a replacement for SF550X-24P-K9-NA, a discontinued 24-port 10/100 PoE stackable switch. The older model reached end of sale June 18, 2020, and support ended June 30, 2025. Migration changes the access-port speed class, so review existing cabling, endpoint requirements, and configuration before ordering.
ORM offers SG550X-24P-K9-NA new sealed or certified refurbished, with up to 3-year extended coverage for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty cannot extend beyond July 31, 2027, the last date of support.
No, the Cisco 550X switch uses an internal AC supply with external RPS2300 support rather than redundant internal supply modules. RPS2300 provides backup power following loss of AC input or internal supply failure. A single RPS2300 can connect to six 550X switches, so redundancy requires separate external hardware.
SG550X-24P-K9-NA powers attached endpoints, while SG550X-24-K9-NA provides 24 Gigabit access ports without PoE. Both models are discontinued. The powered version addresses replacement requirements involving phones, cameras, or access points; the non-PoE version addresses existing installations where endpoints receive power separately and switch-delivered power is not required.
SG550X-48P-K9-NA provides 48 Gigabit powered access ports, while SG550X-24P-K9-NA provides 24. Both models are discontinued. The smaller model addresses replacements requiring the original connection count; the 48-port model addresses denser existing installations, where the additional physical connections are required rather than merely reserved for possible future use.
C1300-24P-4X provides four 10G SFP+ uplinks, while SG550X-24P-K9-NA combines two dedicated SFP+ uplinks with two copper/SFP+ combo uplinks. The discontinued SG550X model addresses like-for-like replacement requirements that include copper uplinks; C1300-24P-4X is the current migration endpoint for buyers standardizing on the successor with SFP+ uplinks.
