SX550X-16FT-K9-UK is a managed Cisco 550X Series stackable switch with 8 x 10G RJ-45 / 8 x 10G SFP+. It combines fixed 10 Gigabit Ethernet connections with web-based configuration for deployments retaining the 550X hardware family. The SFP+ cages require separately selected optical transceivers and fiber patching. This rack-mounted unit has no PoE output; connected endpoints must have their own power arrangement. Hardware stacking enables coordinated operation with compatible 550X members, not arbitrary Cisco switch families. The unit has a dedicated management interface and retains local configuration controls. Its complete PID distinguishes the regional ordering variant and must be matched exactly to purchase records. Cisco stopped selling the family in July 2022, so buyers maintaining an existing installation should distinguish remaining manufacturer support from reseller supplied hardware.

320 Gbps switching capacity handles the model’s 10 Gigabit Ethernet interfaces. 238.08 Mpps forwarding performance specifies the published frame processing scale, and 196.88W is the platform maximum power draw for supply planning. SX550X-16FT-K9-UK uses 512 MB of DRAM and 256 MB of flash for its embedded managed switching software. The 550X platform supports VLAN segmentation, spanning tree controls, link aggregation and local network management. Its Layer 3 functionality includes routing features operated through the embedded switch software rather than Catalyst Network Essentials subscriptions. The chassis supports eight-member hardware stacks using compatible members. It has a standard rack width of 440 mm and a fixed power input rated at 100–240V AC. Dedicated out-of-band management is distinct from forwarding interfaces, and copper/SFP+ combo alternatives share logical port assignments where fitted. Network optics and connection media must be selected separately from the switch hardware. No PoE power is supplied over the access connections.
SX550X-16FT-K9-UK can be sourced through ORM Systems as new sealed or certified refurbished hardware. Refurbished managed units are inspected, bench-tested for power-on, POST, rated port links and clean boot, then firmware-verified and wiped to factory defaults; optics bay recognition and PSU and fan status are checked where fitted. State the exact PID, requested condition and any supported optical components in the order. New units carry up to a 3-year extended ORM warranty and refurbished units up to 1 year, with 30-day returns under terms. For volume procurement, ORM accepts purchase orders, government Net-30 and RMA with advance replacement across the UK, EU, US and MEA.

An existing wiring closet uses a 550X hardware configuration and a failed unit must be replaced without changing the available media. SX550X-16FT-K9-UK offers 8 x 10G RJ-45 / 8 x 10G SFP+. Its fixed interface configuration affects patching, transceiver counts and management recovery. Before the purchase order, confirm the complete PID and record the installed software image.
A site needs to connect fiber runs to an installed 10 Gigabit Ethernet switching environment. SX550X-16FT-K9-UK provides 8 fixed SFP+ positions. SFP-10G-SR and SFP-10G-LR are different optical reach options. Determine each span and fiber type before ordering transceivers and the patch leads.
A maintenance team is arranging spares for aging switch hardware across multiple locations. SX550X-16FT-K9-UK belongs to a family with an end-of-sale date of 30 July 2022 and Cisco support ending 31 July 2027. Confirm whether refurbished stock meets the organization’s service plan, and specify the intended condition and RMA route before ordering.
Power for PoE endpoints
SX550X-16FT-K9-UK has no PoE output for directly powering access points or phones. Select a currently supported Cisco Business PoE series with sufficient aggregate power for the devices.
Manufacturer sales availability
SX550X-16FT-K9-UK is no longer sold by Cisco, with end of sale on 30 July 2022. For a new rollout, evaluate Cisco Business 350 alternatives and verify physical port differences.

SX550X-16FT-K9-UK is a Cisco 550X Series managed 10 Gigabit Ethernet switch with 8 x 10G RJ-45 / 8 x 10G SFP+. The full orderable PID identifies the hardware configuration and any regional variation. The 550X family supports local management and stacking, and this model has no PoE output. Select network media according to its fixed interface layout.
SX550X-16FT-K9-UK is managed with the Cisco 550X embedded administration software and its web configuration interface. The series also provides a standard console port for local access. The platform is not a Meraki Dashboard managed product. Use the appropriate firmware and access controls to provision network settings before connecting production links.
SX550X-16FT-K9-UK was included in the Cisco 550X family end-of-sale announcement, with sales ending 30 July 2022. The last date of Cisco support is 31 July 2027. End of sale does not mean support has already ended. Any service entitlement remains subject to Cisco conditions and the last support date.
SX550X-16FT-K9-UK may be ordered from ORM Systems in new sealed or certified refurbished condition. ORM offers up to a 3-year extended warranty on new products, up to one year on refurbished products, and 30-day returns subject to terms. Cisco’s separate limited lifetime warranty is bounded by its 31 July 2027 end-of-support date.
No, SX550X-16FT-K9-UK does not provide PoE power to connected Ethernet equipment. The ports transport data at the supported Ethernet speeds, while phones, wireless access points and other powered devices require external power or a separate PoE-capable switch. The choice should be based on endpoint power requirements, not only the interface speed.
SX550X-16FT-K9-UK has a fixed port configuration of 8 x 10G RJ-45 / 8 x 10G SFP+. SFP+ interfaces accept the supported 10 Gigabit optical transceiver class, while RJ-45 positions use copper Ethernet cabling. Combo ports share logical connections between copper and optical interfaces rather than increasing independently usable port count. Verify the physical layout before assigning uplinks.
Yes, SX550X-16FT-K9-UK belongs to the Cisco 550X stackable switch family. The 550X platform can form hardware stacks with as many as eight suitable members. Compatibility depends on the exact series and installed firmware. The stacking connections are separate from front-panel data uplinks, so both must be planned in a replacement order.
SX550X-16FT-K9-UK can use documented Cisco SFP+ optical transceivers such as SFP-10G-SR for compatible multimode fiber and SFP-10G-LR for single-mode fiber. The correct module depends on both the fiber medium and distance. Modules are separate components; the switch’s SFP+ cage alone does not include an optic.
Yes, SX550X-16FT-K9-UK is a full-width Cisco 550X switch with a 440 mm chassis and 44 mm height for 1U rack installations. The depth is 350 mm. Rack planning should allow clearance for cables, ventilation, and power connection. Check the rack installation parts and the full hardware PID on the purchase order.
SX550X-16FT-K9-UK has 8 x 10G RJ-45 / 8 x 10G SFP+ and does not supply PoE. Buyers should verify the intended connection media, compatible 550X management configuration and any optical accessories. Cisco ended direct sales on 30 July 2022, with support ending 31 July 2027. Confirm the ordered condition and support expectations independently of the hardware configuration.
