SX550X-12F-K9-UK is a Cisco 550X 12-port 10g sfp+ stackable managed switch built for managed small business access or aggregation. The documented interface layout includes ten dedicated 10G SFP+ ports and two shared 10G copper/SFP+ combo positions. Its 240 Gbps switching capacity and 178.56 Mpps forwarding rate describe this model. The switch uses internal ac psu and a rack-mount 1u installation. No network port supplies PoE, so attached devices need another power source. Before replacing an installed unit, match the physical label, network cable map, and configuration file to the order. The choice of copper or fiber uplink media determines which transceivers or optional modules must be included. This hardware is most suitable when an existing Cisco platform requires the same form factor and established management behavior.

The access and uplink layout of SX550X-12F-K9-UK separates endpoint connections from distribution handoffs: ten dedicated 10G SFP+ ports and two shared 10G copper/SFP+ combo positions. The SFP+ interface positions operate at 10G and require optics suited to the peer and fiber plant. Hardware stacking status is yes - max 8 units, and any stack interconnect is separate from endpoint cabling. The published chassis draw is 25.3W; confirm available power and cooling at the installation site. The managed software should be verified during refurbishment and configuration should be cleared to factory default before redeployment. Check every copper port at its rated speed and confirm optics recognition where SFP cages are present. The two combo positions each use copper or SFP+ media, never both simultaneously; specify 10G optics and the UK mains cord with the chassis.
ORM Systems offers SX550X-12F-K9-UK new sealed and certified refurbished. Refurbished managed units are inspected, bench-tested, firmware verified, and wiped to factory default; copper port links and applicable optics bays are checked. Specify the exact full PID, internal ac psu, installation form, required cables, and any fiber optics or optional modules on the PO. New units carry up to a three-year extended ORM warranty, certified refurbished units up to one year, and both have 30-day returns subject to terms. Purchase orders are accepted, Net-30 is available for government buyers, and RMA with advance replacement is offered across UK, EU, US, and MEA stock locations.

An existing 550X installation needs a like-for-like spare because the chassis and configuration are already deployed. SX550X-12F-K9-UK provides ten dedicated 10G SFP+ ports and two shared 10G copper/SFP+ combo positions. Confirm the exact PID, physical slot or rack position, port map, and existing management configuration before the purchase order.
A distribution connection requires a review of copper and optical media. SX550X-12F-K9-UK has ten dedicated 10G SFP+ ports and two shared 10G copper/SFP+ combo positions. Identify which positions are shared or depend on an optional module, then specify compatible optics, cable lengths, and the peer port speed before the purchase order.
A maintenance team holds a replacement for a deployed 550X switch. SX550X-12F-K9-UK must match the installed software image, power method, and enclosure or rack arrangement. Record the boot result, port-link checks, firmware file, and restoration procedure before the purchase order.
Power to connected endpoints
SX550X-12F-K9-UK has no PoE output. Select a documented powered access platform when attached phones, cameras, or wireless endpoints require power from the switch.
Different physical installation
SX550X-12F-K9-UK uses rack-mount 1u installation with internal ac psu. Select a switch built for the target enclosure or rack where these physical requirements do not match.

SX550X-12F-K9-UK is the Cisco 550X 12-port 10g sfp+ stackable managed switch. Its published port arrangement includes ten dedicated 10G SFP+ ports and two shared 10G copper/SFP+ combo positions. Confirm the exact label on the installed unit because blade enclosure fit, regional supplies, and uplink media can vary by ordered configuration. Match the port map before accepting a substitution.
SX550X-12F-K9-UK provides ten dedicated 10G SFP+ ports and two shared 10G copper/SFP+ combo positions. Access and uplink interfaces serve different roles, and optional uplink modules must be checked in the actual installed chassis. Document each active peer connection, cable type, and optic before replacing the unit so a spare can restore the same links.
SX550X-12F-K9-UK does not provide PoE output on its network interfaces. Attached phones, cameras, and access points need a separate power source or a different powered switch. The chassis power input runs the switch itself and does not establish a shared endpoint power budget. Confirm endpoint requirements before ordering.
SX550X-12F-K9-UK receives power through internal ac psu. Confirm the regional cord, external adapter, or compatible blade enclosure as applicable before ordering. The physical power arrangement must match the installed unit; a switch with the right port count can still fail a replacement if its power connection differs.
SX550X-12F-K9-UK has a documented hardware stacking design. Its stack status is yes - max 8 units, with physical stack links distinct from ordinary access connections. Check member software compatibility and the required stack interconnect before adding a replacement, and retain a saved configuration for the existing installation.
SX550X-12F-K9-UK has a published switching capacity of 240 Gbps and forwarding rate of 178.56 Mpps. These figures belong to this model, while port speed and media still determine actual physical handoffs. Check the installed uplink configuration and peer capacity before approving the replacement order.
SX550X-12F-K9-UK is a standalone switch in rack-mount 1u form, rather than a Dell blade I/O module. It needs its own power connection and physical mounting space. Confirm the existing rack or desktop layout and cable reach before purchasing a replacement for a blade enclosure.
SX550X-12F-K9-UK uses SFP+ media where the applicable fixed interface or optional uplink module is populated. Optics are chosen for fiber type, link distance, and peer speed, then ordered separately unless a quote explicitly includes them. Confirm the actual module and cage on the unit before specifying a transceiver.
SX550X-12F-K9-UK is offered by ORM Systems new sealed or certified refurbished. New units carry up to a three-year extended warranty, while certified refurbished units carry up to one year. Both have 30-day returns subject to terms. Confirm the condition, required accessories, and replacement schedule on the purchase order.
SX550X-12F-K9-UK should be quoted using the full PID and the installation's port and power requirements. ORM Systems accepts purchase orders and offers Net-30 terms for government buyers, with regional stock in the UK, EU, US, and MEA. Confirm optics, modules, and RMA coverage before issuing the PO.
