SG500-52-K9-UK is a Cisco Small Business 500 managed switch with 48 Gigabit access ports and two 1G copper/SFP combo uplinks and two 1G/5G stacking-capable SFP ports. Its managed software supports routed access features and true hardware stacking for up to eight members. Attached endpoints need their own power source. The full-width 1U chassis fits a rack with an internal AC supply. Fixed uplink positions may use supported fiber optics where present, so the fiber type and corresponding transceiver must be specified on the order. The SG500-52 port count and uplink class should match the installed network map. This retired platform is most appropriate where an existing configuration or spare requirement calls for the same hardware family.

120 Gbps switching capacity and 77.38 Mpps forwarding are the published model figures for frame movement and 64-byte packets. SG500-52-K9-UK uses 256 MB of CPU memory and 32 MB of flash for its embedded management software. VLAN configuration, spanning tree, LACP, and monitoring allow port-level control at the small business access edge. The 500 Series can combine up to eight units in one true hardware stack; selected 5G or 10G interfaces carry stack traffic according to model. Unpowered access ports carry data only, leaving endpoint power to other equipment. 2 fixed fans cool the enclosure and their status should be checked during refurbishment. The internal universal AC supply has no standard hot-swappable redundant bay. Confirm that the Rack-Mount 1U installation has enough clearance for the chassis and that the local power connection matches Internal AC PSU.
ORM Systems offers SG500-52-K9-UK new sealed and certified refurbished, with purchase orders accepted in both conditions. Certified refurbished managed units are inspected, bench-tested, firmware verified, and wiped to factory default; every copper port is checked for a link at its rated speed. SFP bay recognition is checked for the built-in optic positions. Confirm the Cisco order number, regional power hardware, and any needed fiber optic before releasing the order. New units carry up to a 3-year extended ORM warranty, refurbished units up to 1 year, and both have 30-day returns subject to terms. Volume buying can use PO acceptance, Net-30 for government, UK/EU/US/MEA regional stock, and RMA with advance replacement.

An installed small business network requires 48 Gigabit copper access ports with the same port density. SG500-52-K9-UK offers two 1G copper/SFP combo uplinks and two 1G/5G stacking-capable SFP ports and unpowered copper endpoints. Check patch-panel assignments, the actual Cisco PID SG500-52-K9-UK, and the local power connection before the purchase order.
A distribution handoff uses fiber rather than copper while 48 Gigabit endpoints remain attached. SG500-52-K9-UK provides two 1G copper/SFP combo uplinks and two 1G/5G stacking-capable SFP ports. The shared combo positions accept a supported MGBSX1 or MGBLX1 optic, which disables the paired copper interface. Confirm the optic, fiber type, and uplink port assignment before the PO.
An existing 500 Series installation adds a chassis to its hardware stack. SG500-52-K9-UK belongs to a family supporting up to eight units, with stack links using documented 5G or 10G ports according to model. Verify stack software compatibility, the chosen interconnect, and available rack power before the purchase order.
Current Cisco service entitlement
Cisco lists the Small Business 500 family as retired. Specify a currently supported Cisco switch when vendor software maintenance or a new service contract is required.
Faster distribution interface
SG500-52 provides 1G uplinks. Choose a current platform with a faster documented uplink class when the distribution link exceeds that rate.
Hot swappable redundant power
SG500-52 has an internal AC power arrangement without a standard second hot-swappable PSU. Choose a current model with a documented redundant supply option if power redundancy is required.
Switch powered network endpoints
The 48 access ports provide no PoE output. Select a current powered access model when phones, cameras, or wireless devices require switch-supplied power.

SG500-52-K9-UK identifies the Cisco SG500-52 48-port Gigabit switch. Its Cisco regional ordering number is SG500-52-K9-UK; the catalog spelling may differ from the physical order PID on older 200 Series units. Check the chassis label, sales region, and powered-port configuration before accepting a substitution.
SG500-52-K9-UK is managed through the 500 Series web interface and command-line management over SSH or Telnet. The platform supports VLAN and port controls, with SNMP monitoring on applicable models. Save the installed configuration and verify firmware before a refurbished unit replaces production hardware.
SG500-52-K9-UK belongs to Cisco's retired Small Business 500 family. Cisco's retired products no longer receive normal vendor support. Existing stock or certified refurbished units can replace deployed hardware, but the purchase plan should include firmware availability, a tested spare, and a separate RMA route.
SG500-52-K9-UK is offered by ORM Systems new sealed or certified refurbished. New units have up to a 3-year extended ORM warranty; certified refurbished units have up to 1 year. Both conditions have 30-day returns subject to terms. Cisco's original limited lifetime hardware coverage ended when the platform was retired.
SG500-52-K9-UK does not supply PoE on its 48 Gigabit copper access ports. Powered devices need another switch or a separate power source. Its uplink ports are data interfaces, not power outputs. Confirm the endpoint power plan before ordering a non-PoE replacement for an existing installation.
SG500-52-K9-UK provides two 1G copper/SFP combo uplinks and two 1G/5G stacking-capable SFP ports. Its published uplink speed class is 1G, and optical modules must be matched to the installed fiber. Verify the active uplink media and the distribution switch's matching interface before purchase.
SG500-52-K9-UK can join a Small Business 500 hardware stack of up to eight units. The 500 family uses selected 5G or 10G ports for physical stacking, depending on the model. Check member software compatibility, port allocation, and interconnect media before expanding a production stack.
SG500-52-K9-UK belongs to the 500 Series managed platform, which supports Layer 3 switching features including static routing. It is not supplied with an enterprise Catalyst license tier. Check the installed routing configuration and stack software before moving the chassis into a routed access role.
SG500-52-K9-UK uses internal ac psu with a 100–240V AC supply connection. The published maximum draw is 47W for the documented configuration. Confirm the regional cord or adapter and local rack capacity before purchase. Verify the actual chassis label, required media, and saved configuration before the purchase order.
SG500-52-K9-UK has a published 120 Gbps switching capacity and a separate 77.38 Mpps forwarding rate for small packets. These figures describe this model rather than another member of the family. They should be compared with the existing uplink layout and access-port speeds when checking replacement suitability.
