SG500-52P combines 48 Gigabit Ethernet PoE+ access ports with four additional Gigabit interfaces in a managed, stackable rack-mount switch. Two uplink interfaces are shared copper/SFP combo ports; the other two SFP interfaces support Gigabit network connections or 5G stacking operation. The Small Business 500 family serves business networks connecting computers, IP phones, wireless access points and surveillance cameras. Static IPv4 and IPv6 routing extend switching beyond Layer 2, placing this configuration in the Layer 2+ category. The discontinued SG500-52 provides the corresponding non-PoE configuration. A 48-port Gigabit PoE+ access switch supplies endpoint power through Ethernet cabling, but the aggregate power allocation remains separate from the maximum supported by an individual port.

120 Gbps switching capacity supports wire-speed, nonblocking operation, while 77.38 Mpps forwarding performance specifies handling of 64-byte packets. 375W of shared PoE capacity must cover the combined allocation to powered endpoints rather than a simultaneous maximum on every connection. Static routing supports IPv4 and IPv6 traffic between network segments. SG500-52P carries 256 MB of DRAM and 32 MB of flash for its embedded operating software and configuration. The MAC address table accommodates 16384 entries, and VLAN support extends to 4096 VLANs. STP/RSTP/MSTP provide spanning-tree control, while LACP supports aggregated Ethernet links. Administrators can configure the platform through its browser interface or Textview CLI, with SSH available for encrypted command-line sessions. Four speed-controlled fans provide active cooling. The fixed uplink hardware does not provide 10G network connections; the higher-speed operating mode on the dual-purpose SFP interfaces is for stacking.
ORM Systems offers SG500-52P in new sealed and certified refurbished condition; refurbished units are inspected and bench-tested, with power-on and POST, rated-speed port links, clean boot, optics recognition, fan status and PoE output under load verified, and firmware checked before configuration is wiped to factory default. Specify the condition, quantity, regional power connection and required accessories on the purchase order. New units carry up to a 3-year extended ORM warranty and certified refurbished units up to 1 year, with 30-day returns on every condition; terms apply. PO acceptance, government Net-30, RMA with advance replacement, and regional stock/RMA coverage across the UK, EU, US and MEA support enterprise and volume orders.

When a purchase covers several existing sites, editable text configuration files allow a common setup to be prepared before equipment reaches each location. SCP supports configuration-file transfer, and automated configuration can retrieve settings centrally. Specify the required configuration baseline and the staging procedure before releasing the purchase order.
When an existing installation needs another stack member, ring and chain topologies create different connection plans. Automatic unit numbering and primary/backup stack control affect how the added unit enters the installation. Confirm the existing topology, firmware alignment and available interconnection interfaces before specifying the additional unit and its connection materials.
When a retained switch is being purchased for troubleshooting or staging, port mirroring can direct traffic from eight source ports to one destination port. VLAN mirroring provides another capture option. Define the capture destination, source-interface selection and configuration reset procedure before ordering equipment for the bench.
10G network uplinks to distribution
SG500-52P provides Gigabit network uplinks; its 5G operation is reserved for stacking. A requirement for 10G network uplinks exceeds this model's fixed interface capabilities.
Maximum PoE+ on every powered port
SG500-52P cannot allocate 30W simultaneously to all 48 powered ports because their combined maximum exceeds its shared budget. Size the complete endpoint allocation before selecting powered access hardware.
Active Cisco manufacturer support coverage
SG500-52P has no remaining Cisco support coverage because service ended April 30, 2023. Orders requiring active manufacturer service must exclude this retired product.

SG500-52P identifies a Gigabit Ethernet model in the 500 family, with 52 logical Ethernet interfaces and PoE+ on its 48 access ports. The remaining four interfaces provide uplink or stacking connectivity. P identifies the powered configuration, and the corresponding Cisco product-order identifier is SG500-52P-K9.
SG500-52P supports browser-based management over HTTP or HTTPS, the Textview CLI through console, SSH or Telnet, and SNMP management. SNMP versions 1, 2c and 3 are supported. Administrators can use the graphical interface for configuration and monitoring or the CLI for command-driven administration.
SG500-52P is discontinued, and Cisco support has ended. The Small Business 500 family reached end of sale on April 12, 2018, and its last support date was April 30, 2023. Retained inventory does not restore manufacturer support or extend that lifecycle milestone.
SG500-52P is offered new sealed or certified refurbished, with ORM warranty coverage up to 3 years extended for new units and up to 1 year for refurbished units. Returns are available for 30 days on every condition; terms apply. Cisco's original limited lifetime hardware warranty ended April 30, 2023.
SG500-52P provides a shared 375W PoE budget across 48 powered Gigabit access ports, with a maximum supported allocation of 30W on an individual port. The switch supports PoE and PoE+ devices. The total budget does not permit every powered port to receive its maximum allocation simultaneously.
SG500-52P has two Gigabit copper/SFP combo interfaces and two SFP interfaces supporting 1G network links or 5G stacking operation. Gigabit fiber options include MGBSX1 for multimode connections and MGBLX1 for single-mode connections. Each combo interface uses either its copper connection or its SFP connection, not both simultaneously.
Small Business 500 hardware stacking supports eight members with a single management address. SG500-52P supports 5G copper stacking connections using SFP-H10GB-CU1M, SFP-H10GB-CU3M or SFP-H10GB-CU5M. Ring and chain connections are supported, so interconnect length and topology must be specified for the existing installation.
SG500-52P supports static IPv4 and IPv6 routing between network segments, including VLAN interfaces. IPv4 capacity reaches 2048 static routes and 256 IP interfaces. These static-routing capabilities place the switch in the Layer 2+ category; they are separate from its Ethernet switching, VLAN segmentation and spanning-tree functions.
The SG500-52P 48-port Gigabit PoE+ switch uses an internal universal AC power supply accepting 100-240V AC. Maximum consumption including PoE is 460.5W at 110V. Its standard configuration does not include redundant power modules, so equipment power planning must distinguish upstream power protection from internal supply redundancy.
SG500-52P supplies PoE+ to 48 access ports, whereas SG500-52 does not supply endpoint power. Both configurations retain Gigabit access connectivity and the same uplink arrangement. Both models are discontinued; the powered configuration matches retained installations with Ethernet-powered endpoints, while the non-PoE configuration matches separately powered devices.
SG500-52P has 48 powered Gigabit access ports, whereas SG500-28P has 24 powered Gigabit access ports. Both retain four additional Gigabit interfaces. Both models are discontinued; the larger configuration matches retained installations requiring greater connection density, while the smaller configuration matches installations with fewer access connections.
SG500-52P provides Gigabit network uplinks, whereas SG500X-48P provides four 10G SFP+ interfaces. Both have 48 powered Gigabit access ports. Both models are discontinued; SG500-52P matches retained Gigabit uplink installations, while SG500X-48P matches retained installations whose existing upstream connections require the higher-speed SFP+ interface arrangement.
