SG500-52MP-K9 is a Cisco 500 Stackable Managed Switches rack-mount managed switch providing 48 1GbE RJ-45 access ports and Gigabit SFP and combo positions that can serve uplinks or a hardware stack. All 48 access ports support PoE+ with a shared 740W allocation for phones, cameras and wireless access points. The embedded Layer 2+ feature set covers segmented small-business access networks and static routed VLAN interfaces. Cisco SG500-52MP hardware can replace like-for-like 500 inventory where the installed configuration depends on the original generation of interfaces. The fixed uplink architecture leaves no removable network module bay; choose transceivers and stack connectivity as separate items. The chassis is designed for a full-width equipment rack rather than desktop placement, with the regional hardware suffix retained on procurement records.

120 Gbps switching capacity and 77.38 Mpps forwarding throughput establish the hardware performance for this configuration. 740W of combined PoE+ power is allocated to endpoints instead of being individually reserved across all 48 powered ports. SG500-52MP-K9 has 16384 learned MAC entries, supports 2048 IPv4 static routes, and uses integrated management rather than Cisco Network Essentials or Network Advantage licensing. Static routing provides basic Layer 3 forwarding without 500X-only RIP v2 and VRRP capabilities. The embedded web interface is accessible over HTTP/HTTPS; command-line administration supports secure SSH alongside Telnet, and an integrated serial interface provides local recovery access. RSTP/MSTP and LACP support resilient Ethernet topologies, and IPv4 VLAN interfaces permit routing between configured subnets. The physical stack treats its members as one managed system. Gigabit and dedicated stack-mode interfaces need port allocation before commissioning. Confirm the required firmware release and active forwarding modes when extending an installed stack.
SG500-52MP-K9 is offered by ORM Systems in new sealed and certified refurbished condition. Certified refurbished managed switches are inspected and bench-tested for power-on, POST, clean boot and correct link speed on every port; firmware is verified and prior configuration is wiped to factory defaults. Each powered port is also checked under PoE load. Order this exact suffix with any transceiver, cable and rack accessory PIDs required for the installation. ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished equipment; 30-day returns apply to both conditions under the stated terms. For enterprise or volume requests, purchase orders, government Net-30 terms and RMA with advance replacement are available across UK, EU, US and MEA stock.

Lifecycle Status | Support ended 30 April 2023 |
An established equipment rack needs a like-for-like replacement for a SG500-52MP chassis without revising the cabling design. The 48 fixed Gigabit interfaces define the compatible edge density, while existing management settings require a planned restore or fresh configuration. Match the precise regional ordering suffix, port mapping and physical rack clearance before issuing the purchase order.
A wiring closet refresh retains PoE+ access points, phones and security equipment with a combined power requirement. The SG500-52MP variant distributes 740W across 48 powered ports, so per-port capability is not an aggregate guarantee. Add each endpoint maximum draw, retain the required cable runs, and reconcile the shared power total before placing the purchase order.
A maintenance inventory needs a ready spare for a retired 500 access switch serving 48 Gigabit endpoints. Vendor support ended on 30 April 2023, so the replacement process depends on tested reseller stock and internal change controls. Record the full PID, firmware baseline, management credentials and required RMA response arrangements before approval.
Current Cisco manufacturer support
SG500-52MP-K9 passed its last support date on 30 April 2023. For deployments requiring current vendor service, evaluate the Cisco Business 350 family instead of this retired device.
Native multigigabit copper access
SG500-52MP-K9 has Gigabit Ethernet copper downlinks rather than 2.5G or 5G ports. Review a currently supported Cisco multigigabit access platform for faster RJ-45 endpoints.
Unrestricted full load PoE power
SG500-52MP-K9 shares 740W across 48 PoE+ ports; simultaneous 30W delivery to every port would need 1440W. Select a current higher-budget Cisco platform if required.
Fixed ten gigabit uplinks
SG500-52MP-K9 uses 1G Gigabit uplinks rather than 10G SFP+ data links. The current Cisco Business 350 family includes configurations with documented 10G uplinks.

SG500-52MP-K9 identifies the Cisco SG500-52MP hardware variant in the Small Business 500 stackable managed switch range. The base model defines the 48 Gigabit access ports and its specified uplink and power hardware. Its remaining ordering elements distinguish the exact commercial or regional form, so the complete PID belongs on every replacement purchase.
SG500-52MP-K9 is managed through its local embedded web interface using HTTP or HTTPS, through its command-line interface over SSH or Telnet, and through serial console access. The unit does not require Cisco Meraki Dashboard licensing. Keep the firmware version and administrator configuration consistent across any installed hardware stack members.
Yes, Cisco support for SG500-52MP-K9 ended on 30 April 2023 as part of the retired 500 Series. End of sale was 12 April 2018. Cisco manufacturer service is therefore no longer active, so continued operation depends on existing equipment management and any independent reseller replacement arrangements.
SG500-52MP-K9 has no active Cisco manufacturer hardware support after 30 April 2023. ORM Systems offers new sealed devices with up to a three-year extended warranty and certified refurbished units with up to one year. Both conditions carry a 30-day return window subject to terms, separate from the expired Cisco manufacturer coverage.
SG500-52MP-K9 has 48 fixed Gigabit RJ-45 access ports. The 500 configuration has Gigabit SFP and combo interfaces alongside access ports. The physical stack connectors and any shared combo positions must not be counted as additional independent endpoint connections. For an exact replacement order, match the complete model and regional suffix to the installed hardware, including management and electrical requirements.
SG500-52MP-K9 provides PoE+ on 48 Gigabit ports with a shared 740W power budget. Each connected powered endpoint draws from the same overall allocation, which cannot be interpreted as 48 independent 30W grants. Match power demand to the specific hardware form rather than assuming the entire family has identical power capability.
Yes, SG500-52MP-K9 supports a hardware stack of eight managed units in the Cisco 500 family. Stack compatibility extends across documented SF500, SG500 and SG500X members. Stack links require appropriate port assignments and compatible cabling; the shared management plane should not be confused with independent cloud dashboard grouping.
SG500-52MP-K9 has Gigabit SFP and shared combo uplink facilities, without a native 10 Gigabit data-uplink interface. Transceiver selection must follow the installed fiber type and reach. A shared stack-mode position cannot simultaneously be allocated to an ordinary network uplink. For an exact replacement order, match the complete model and regional suffix to the installed hardware, including management and electrical requirements.
SG500-52MP-K9 provides static IPv4 routing within its embedded Layer 2+ administration environment, without the RIP v2 and VRRP features specific to the 500X family. The platform supports 2048 static IPv4 routes. These capabilities do not imply Network Advantage entitlement or enterprise OSPF/BGP routing support.
SG500-52MP-K9 uses a 1U rack-mount chassis with 440 mm width and an internal universal 100-240V AC input. The hardware includes cooling fans rather than passive fanless operation. Plan rack depth for the 350 mm enclosure, appropriate airflow, connected electrical load and the correct regional power cord.
