SG500-28MPP-K9-G5 is a managed 24-port Gigabit Ethernet switch from the Cisco Small Business 500 Series family. The fixed copper downlinks deliver PoE+ for connected phones, cameras and access points, using a shared 740W budget. The unit has 4 Gigabit uplink interfaces with dual-use 1G/5G stacking support. The rack-oriented platform is intended for small-business access aggregation, switch replacement and matching hardware across existing installations. The 500 family supports hardware stacking and shared-purpose high-speed uplink arrangements. Buyers should distinguish its actual physical interfaces from network modules or transceivers that may be listed separately. The correct region and hardware suffix must match the item received, especially for multi-site spares. Cisco manufacturer support has ended for this retired family.

SG500-28MPP-K9-G5 supports configurable VLAN-based forwarding, web administration and static IPv4 routing in the managed switch software. The 500 series provides hardware stacking, so uplink and stack interface allocation must be planned as one physical port inventory. Endpoint power is allocated from the chassis-wide shared PoE pool, not a separately dedicated full-load allowance per interface. Configuration backup and software-version identification matter for replacement stock, especially when an installed environment still relies on an older feature profile. The full part number should be matched to the existing switch configuration rather than selected from port count alone. Cisco service and security software maintenance have already ended; replacement planning therefore affects operational support even when the hardware boots and forwards traffic.
ORM Systems offers SG500-28MPP-K9-G5 new sealed and certified refurbished, with purchase orders accepted for individual replacements and volume purchases. Certified refurbished managed units are inspected and bench-tested for power-on, POST, clean boot, every port linking at rated speed, firmware verification and configuration reset to factory defaults. Powered ports are tested under load for PoE output. New units are eligible for up to a 3-year extended ORM warranty and certified refurbished units for up to a 1-year ORM warranty; all conditions include a 30-day return period subject to terms. Government buyers can use Net-30, with RMA advance replacement available. Regional stock and RMA handling cover the UK, EU, US and MEA; confirm quantity, condition and included accessories on the order.

An existing estate already uses Cisco Small Business 500 Series and requires a direct spare for a failed member. SG500-28MPP-K9-G5 retains the 24-port access configuration, allowing the port map to be reviewed without assuming a different family shares its feature set. Confirm the installed software release, power arrangement, and exact ordering suffix before issuing a purchase order.
A location plans to power phones and wireless access points from its access switch. SG500-28MPP-K9-G5 supplies 740W shared across 24 PoE+ ports, so device startup and peak draws must be summed for the planned connected load. Document the per-endpoint requirement and aggregate power allocation before finalizing the purchase order.
A maintenance team holds a small spare pool for the 500 Series at multiple sites. SG500-28MPP-K9-G5 should be matched against installed software configuration and labeled cabling rather than selected solely by the series name. Confirm condition, tested interface operation, and dispatch region before setting the purchase quantity.
Active Cisco hardware support
SG500-28MPP-K9-G5 is beyond Cisco support and cannot provide an active manufacturer service entitlement. Consider a current Cisco Business switching family with the required port count and management features.
Ten gigabit fiber uplinks
SG500-28MPP-K9-G5 provides 4 Gigabit uplink interfaces with dual-use 1G/5G stacking support; 10G fiber uplinks are not part of this unit.
PoE demand above shared allowance
SG500-28MPP-K9-G5 has a shared 740W PoE budget across 24 access ports. A network requiring greater simultaneous power needs a model with a larger documented budget.

SG500-28MPP-K9-G5 is a 24-port Gigabit managed Ethernet switch in the Cisco Small Business 500 Series family. It supplies PoE+ from the shared power pool. The unit provides 4 Gigabit uplink interfaces with dual-use 1G/5G stacking support. Match the complete suffix when checking existing inventory, mounting, and power requirements.
SG500-28MPP-K9-G5 is managed through the embedded web-based switch configuration utility. Administrators can configure VLANs, port settings, and forwarding behavior rather than relying on an unmanaged plug-and-play profile. Confirm the management IP address and software revision of a refurbished unit before attaching it to the production management network.
SG500-28MPP-K9-G5 is no longer supported by Cisco; manufacturer service ended 30 April 2023. The device can still be used in an existing estate, but Cisco service and security updates should not be assumed. Evaluate support obligations and replacement planning separately from physical hardware condition.
SG500-28MPP-K9-G5 is offered by ORM Systems new sealed or certified refurbished. New units carry up to a 3-year extended ORM warranty; certified refurbished units carry up to a 1-year ORM warranty. All conditions allow returns within 30 days, subject to terms. Cisco service has ended.
SG500-28MPP-K9-G5 provides 24 fixed Gigabit Ethernet RJ-45 access ports. The uplink interfaces are separate from that downlink count, and shared combo interfaces must not be added twice when estimating physical connectivity. Confirm the number of devices, reserved management links, and planned uplink media before ordering.
SG500-28MPP-K9-G5 supports PoE+ on 24 Gigabit access ports with a shared 740W pool. Individual ports do not guarantee that all connected devices can draw their maximum simultaneously. Add endpoint power needs and compare the aggregate against the switch allowance before connecting cameras, phones, or wireless devices.
SG500-28MPP-K9-G5 provides 4 Gigabit uplink interfaces with dual-use 1G/5G stacking support. Port assignment must distinguish normal data uplinks from dedicated stack roles. Plan optics, copper connections and spare interfaces against the actual fiber or copper media in the network rather than treating all front-panel connectors as independent ports.
SG500-28MPP-K9-G5 belongs to a full-width rack switch family designed for network cabinet deployments. Confirm that the correct rack ears, fixing hardware and power cord are included with the quoted condition. A refurbished unit should be checked for physical fit, airflow clearance and access to the management and uplink connections.
SG500-28MPP-K9-G5 provides managed VLAN-aware switching and supports a Layer 3 operating mode with IPv4 static routing in the Cisco Small Business 500 Series software family. It should not be treated as a substitute for a full enterprise routing platform. Verify the planned VLAN gateway configuration and route scale before deployment.
SG500-28MPP-K9-G5 should be quoted against the full PID, the 24-port hardware requirement, and the intended uplink connections. The 740W PoE budget also needs to cover connected endpoint load. Confirm mounting components, power cord, condition, and destination region on the purchase order.
SG500-28MPP-K9-G5 is in the Cisco 500 Series stackable managed family and uses dedicated stacking functionality on supported interfaces. The stacking plan must reserve the required ports and match compatible devices and firmware before joining production units. Do not treat an ordinary management grouping as a hardware stack.
SG500-28MPP-K9-G5 is retired from Cisco manufacturer support. Cisco Business switching products are the migration family for legacy Small Business installations, but the substitute must be selected on current lifecycle status and exact port, PoE, uplink, and management requirements. A nominally similar part number does not prove compatibility.
