SG550XG-24F-K9-NA provides 24 fixed 10 Gigabit connections in a managed, non-PoE, 1U rack-mounted switch: 22 dedicated SFP+ ports and two copper/SFP+ combo uplinks. The fiber-focused configuration serves aggregation links and connections to servers or network storage rather than powering endpoints. Within the Cisco 550X Series, the discontinued SG550X-24P-K9-NA offers PoE+ on Gigabit copper access ports instead, making endpoint power a materially different purchase requirement. Static routing and RIP v2 place this configuration in the Layer 2+ category, with additional gateway and policy controls available without changing the physical port arrangement. The fixed uplink architecture accepts optics directly; there is no removable uplink card to specify. Each combo uplink uses either its copper connection or its fiber connection, not both simultaneously.
SG550XG-24F-K9-NA price for new stock is $6,625.98. SG550XG-24F-K9-NA refurb price is $4,188.45. SG550XG-24F-K9-NA is in stock and available for next-day dispatch. (terms applied)

480 Gbps switching capacity and 357.12 Mpps forwarding at 64-byte packet sizes establish the forwarding limits for traffic sizing. 7168 IPv4 routes provide the routing-table ceiling; PBR controls next-hop selection, while VRRP supports redundant default gateways. SG550XG-24F-K9-NA carries 512 MB of memory, 256 MB of flash and a 2 MB shared packet buffer, separating control-plane storage from packet buffering. The MAC table accommodates 32000 entries for endpoint learning. Management access includes a browser interface and Textview CLI, with SSH available for remote administration and a dedicated Gigabit out-of-band management connection. Four primary fans and one redundant fan provide active cooling, so installation planning must account for fan noise rather than assume silent operation. 77.5W maximum consumption provides the chassis load figure for power planning. Operation spans 0°C to 50°C; power redundancy depends on an external system rather than a second internal supply bay.
Specify SG550XG-24F-K9-NA in new sealed or certified refurbished condition, with accessory quantities stated on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links, optics bay recognition, PSU status and fan status; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition, terms apply; Cisco's original limited lifetime hardware warranty ended June 30, 2025. POs are accepted, with Net-30 for government, RMA with advance replacement and UK, EU, US and MEA regional stock/RMA support; include volume quantities in the order.

When expanding an existing 550X stack, plan the interconnect topology before assigning production links. Ring and chain arrangements are supported, and link aggregation can serve the stack interconnect. Mixed SF550X, SG550X, SG550XG and SX550X members are permitted. Check the existing member configuration and reserve interconnect ports before the purchase order.
When consolidating gateway interfaces onto an existing switching installation, compare the addressing plan with the available interface scale rather than counting physical connections alone. The switch supports 256 IP interfaces and 1792 IPv6 static routes. Check required interfaces and IPv6 destinations against those separate ceilings before specifying the order.
For a lab or staging purchase, prepare the image-transfer and configuration workflow before equipment arrives. Dual software images support image staging, while the front USB Type-A connection supports file and image management. Specify the intended image, configuration transfer method and acceptance checks in the staging instructions accompanying the purchase order.
PoE power for connected endpoints
SG550XG-24F-K9-NA does not supply PoE. Connected endpoints requiring power through their Ethernet connection need a separate power source or a powered access-switch design.
Two internal redundant power supplies
SG550XG-24F-K9-NA uses internal AC power with external power-redundancy support, not two internal redundant supply bays. An internal dual-supply requirement needs a different chassis architecture.
New deployments requiring Cisco service
Cisco service ended June 30, 2025. C1300-24XS is the current forward migration destination; its configuration includes four shared copper connections rather than this model's two.

SG550XG-24F-K9-NA identifies the Americas-region 24-port 10 Gigabit SFP+ managed switch in the 550X family. The 24F configuration includes two copper/SFP+ combo connections and one dedicated Gigabit management connection. NA selects the regional ordering variant covering the United States, Canada, Mexico and other listed Latin American markets.
SG550XG-24F-K9-NA supports HTTP/HTTPS browser management, Textview CLI through the console or SSH/Telnet, SNMP versions 1, 2c and 3, Smart Network Application, and FindIT management tools. FindIT paths include Network Manager, Probe and Network Discovery Utility. A dedicated Gigabit out-of-band port provides a separate management connection.
Yes, SG550XG-24F-K9-NA reached end of sale on June 18, 2020, and its last date of Cisco support was June 30, 2025. Cisco service has ended. Software maintenance ended June 18, 2021, so an order must account for an obsolete product rather than an actively supported switch.
ORM offers SG550XG-24F-K9-NA new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Returns are available for 30 days on every condition; terms apply. Cisco's original limited lifetime hardware warranty is no longer active because Cisco service ended June 30, 2025.
SG550XG-24F-K9-NA supports a hardware stack of eight members using standard 10G fiber or copper connections. Ring and chain topologies are available, and aggregated links can carry stack traffic. Supported cable choices include SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M; reserve network ports for the chosen interconnect arrangement.
The 550X fiber switch supports SFP-10G-SR for multimode links and SFP-10G-LR for single-mode links. SFP-10G-LR supports a maximum distance of 10 km, while SFP-10G-SR reach depends on the multimode fiber. Match the transceiver, fiber type and far-end interface before completing the accessory order.
SG550XG-24F-K9-NA provides static routing, RIP v2, PBR and VRRP, with a maximum of 7168 IPv4 routes. IPv6 static routing supports 1792 routes. These capabilities support gateway and next-hop control, but the route-table ceiling and the separate limit of 256 IP interfaces must both fit the intended configuration.
SG550XG-24F-K9-NA uses an internal universal AC supply accepting 100-240V AC at 47-63 Hz. Maximum consumption is 77.5W. Power redundancy comes through an external redundant power system, not a second internal supply. A requirement for two internal power modules therefore cannot be satisfied by this chassis.
The 24-port SFP+ configuration provides 24 simultaneous network connections: 22 dedicated SFP+ connections and two combo connections. Each combo connection selects copper or SFP+, so the extra copper sockets do not create additional simultaneous links. The dedicated Gigabit out-of-band management connection is separate from those network connections.
SG550X-24P-K9-NA supplies PoE+ from Gigabit copper access ports with a 195W budget, whereas SG550XG-24F-K9-NA provides non-PoE 10G fiber connectivity. Both models are discontinued. The former addresses powered copper endpoint requirements in an existing installation; the latter addresses fiber aggregation or matching 10G replacement requirements.
SG550XG-24F-K9-NA provides 24 network connections, while SG550XG-8F8T-K9-NA provides 16, divided between eight copper and eight dedicated SFP+ connections. Both models are discontinued. The 24-port model fits higher fiber connection counts in an existing installation; the 16-port model fits an established mixed copper-and-fiber configuration.
SG550XG-24F-K9-NA has two shared copper/SFP+ connections, while C1300-24XS has four shared copper connections within its 24-port SFP+ configuration. C1300-24XS is the current forward migration destination through the discontinued SX550X-24F-K9-NA and CBS350-24XS-NA. The older model addresses matching spares; C1300-24XS addresses a new replacement purchase.
