SG550XG-48T-K9-NA is a managed, non-PoE 10 Gigabit Ethernet switch with 46 dedicated copper access ports and two additional copper/SFP+ combo connections. Each combo connection operates through either its copper interface or its fiber interface, not both simultaneously. The fixed uplink arrangement requires no removable uplink card. This rack-mount model belongs to the Cisco 550X Series and supports hardware stacking for installations that administer several switches as one system. Its copper-focused configuration serves equipment that has its own power source rather than endpoints requiring power over the network cable.

960 Gbps switching capacity and 714.24 Mpps forwarding at 64-byte packet size describe the switching fabric and packet-processing limits. SG550XG-48T-K9-NA includes 512 MB of memory, 256 MB of flash, and a dynamically shared 4 MB packet buffer. Static routing, RIP v2, VRRP, and PBR support routed configurations; STP, RSTP, MSTP, and LACP support switched-link control. Browser-based administration and a scriptable CLI provide local configuration paths, while a dedicated Gigabit management interface supports out-of-band access. Power redundancy uses an external RPS connection rather than a second internal redundant supply.
ORM Systems offers SG550XG-48T-K9-NA new sealed or certified refurbished; refurbished units are inspected and bench-tested, every port links at rated speed, optics bay recognition is checked, firmware is verified, and configurations are wiped to factory default. New units carry up to a 3-year extended ORM warranty, certified refurbished units carry up to 1 year, and every condition has 30-day returns; terms apply. Specify the required condition and quantities on the order; Cisco's former limited lifetime coverage ended June 30, 2025. POs are accepted, government buyers can use Net-30, and RMA with advance replacement is available through UK, EU, US, and MEA regional stock and RMA arrangements.

For a copper-connected equipment consolidation, qualify the installed cabling before selecting patch leads. Category 6a supports 10 Gigabit connections over channels reaching 100 m. Reconcile the equipment locations, channel lengths, and far-end interfaces, then specify the required cable quantities on the purchase order.
When extending an existing 550X installation, decide whether the added member belongs in a ring or chain. Mixed SF550X, SG550X, SG550XG, and SX550X stacks are supported. Confirm the existing members and reserve the necessary front-panel interconnect ports before specifying the connecting media.
Active Cisco service coverage
Cisco service ended June 30, 2025. The migration chain ends at discontinued CBS350-48XT-4X-NA, with no current migration product named for that model.
PoE-powered endpoint connections
The copper interfaces do not supply PoE. Endpoints requiring cable-delivered power need a separately powered design rather than this switch alone.

No, SG550XG-48T-K9-NA does not supply PoE to connected devices. Its copper connections carry network traffic, so connected equipment needs another power source.
SX550X-52-K9-NA was the direct replacement for SG550XG-48T-K9-NA and is discontinued. Its replacement, CBS350-48XT-4X-NA, is also discontinued, with no current migration product named.
SG550XG-48T-K9-NA has 48 copper-capable connections, while SG550XG-24T-K9-NA has 24. Both include two shared copper/SFP+ connections and are discontinued; the difference matters when matching legacy copper connection density.
SG550XG-48T-K9-NA is copper-focused, while SG550XG-24F-K9-NA provides 24 SFP+ interfaces, including two shared copper connections. Both are discontinued; the former matches copper-oriented legacy installations and the latter fiber-oriented installations.
