SG300-52P provides 48 Gigabit PoE+ access ports and fixed Gigabit uplinks in a managed, rack-mount switch for small-business networks. Two additional copper connections and two copper/SFP combo interfaces provide the uplink connections; each combo interface uses either its copper connection or its fiber connection at one time. The Small Business 300 family combines managed Ethernet access with Layer 2+ functionality for office networks and powered endpoints. The 52-port Gigabit PoE managed switch accommodates copper endpoint connections alongside a choice of copper or fiber connections upstream, without a removable uplink card. SG300-52MP is the discontinued higher-budget PoE+ sibling, distinguishing legacy configurations by their available endpoint-power allocation rather than their connection count.

104 Gbps switching capacity supports nonblocking forwarding across the port configuration. 77.38 Mpps forwarding performance is rated with 64-byte packets, providing the packet-processing figure for evaluating small-packet traffic. 375W of shared PoE power sets the aggregate allocation available to powered endpoints; an unused data port does not increase that allowance. Static IPv4 routing supports 512 route entries without dynamic route exchange. SG300-52P supports STP/RSTP/MSTP for Layer 2 loop control, while HTTPS protects browser-management traffic and SSH provides a secure alternative to Telnet. Four fans cool the switching and power hardware within an operating range of 0°C to 45°C. 473.62W worst-case consumption at 110V provides the maximum AC load figure for circuit sizing, rather than treating the endpoint-power allowance as the switch's electrical draw.
ORM Systems supplies SG300-52P new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for certified refurbished units; returns cover 30 days on every condition, and terms apply. Certified refurbished units are inspected and bench-tested for power-on, POST, clean boot, and every port linking at rated speed, with PoE output verified under load on every powered port; firmware is verified and configurations are wiped to factory default. Specify condition, quantity, and power-cord region on the purchase order; Cisco's original limited lifetime hardware warranty and service ended October 31, 2023. Enterprise and volume orders can use accepted POs, Net-30 for government, and RMA with advance replacement, with regional stock and RMA across the UK, EU, US, and MEA.

When an office consolidation requires traffic to move between existing networks, the hardware allows 128 IP interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. Specify which networks require an interface and which upstream device handles external traffic before raising the purchase order.
When expansion requires multiple connections to be grouped into aggregated links, LACP allows 8 groups, each limited to 8 active ports. Record every group's member ports and peer configuration, then reserve the remaining connections for endpoints. Finalize the port allocation and required switch quantity before issuing the purchase order.
Before a laboratory purchase is used to validate an existing packet-size policy, account for the hardware's maximum frame size of 9216 bytes. Check the intended frame size against every peer in the test path. Include peer-port settings and the test configuration in the staging requirements before ordering units.
10G uplinks to upstream switches
SG300-52P's fixed uplinks are limited to 1G. C1300-48P-4X retains 48 Gigabit access ports but provides four 10G SFP+ uplinks for purchases requiring faster upstream connections.
Active Cisco hardware service eligibility
Cisco service for SG300-52P ended October 31, 2023. The replacement chain ends at C1300-48P-4G, with 48 Gigabit PoE ports and four 1G SFP uplinks.
Endpoint power allocation exceeding 375W
SG300-52P shares 375W across its powered ports. An endpoint plan exceeding that aggregate allocation is outside the switch's power capacity, regardless of unused data connections.

SG300-52P identifies a Gigabit managed switch in the 300 family, with 52 network ports and a PoE+ configuration. SG300 names the Gigabit family, 52 describes the total connection count, and P identifies the powered variant. The configuration includes 48 powered ports, additional copper connections, and two copper/SFP combo interfaces.
Cisco Small Business 300 Series Managed Switches support browser-based management, CLI access over SSH or Telnet, and SNMP. HTTPS encrypts browser-management traffic, while SSH provides secure terminal access. Select the management services and access settings before loading the site configuration, matching the browser, terminal, and monitoring methods used by the engineering team.
SG300-52P is discontinued: end of sale was October 4, 2018, and Cisco support ended October 31, 2023. Software maintenance releases ended October 4, 2019. A new sealed unit does not restart those lifecycle milestones, so procurement must treat the hardware as an unsupported legacy product.
ORM Systems offers SG300-52P new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for certified refurbished units. Returns cover 30 days on every condition; terms apply. Cisco's original limited lifetime hardware warranty ended with service on October 31, 2023.
375W is shared across the 48 PoE+ ports on SG300-52P. Size the purchase against each endpoint's requirement and the combined allocation rather than assuming every powered connection can supply unrestricted power simultaneously. Additional copper connections and the combo interfaces do not increase the available endpoint-power budget.
SG300-52P provides fixed Gigabit connections, including two copper/SFP combo interfaces that each use one medium at a time. MGBSX1 supports multimode fiber links reaching 300 m, while MGBLX1 supports single-mode links reaching 10 km. Specify the required transceiver PID and match the peer interface and installed fiber before ordering.
Cisco 300 Series Switches support static IPv4 routing with 512 static routes and 128 IP interfaces. Routing interfaces can be configured on physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. This is static routing rather than dynamic route exchange, so define the required interfaces and route entries before staging.
Yes, the 52-port Gigabit PoE managed switch SG300-52P uses a 1U rack chassis measuring 440 mm wide, 44.45 mm high, and 350 mm deep. The hardware weighs 5.3 kg and uses four fans. Check cabinet depth, cable clearance, and airflow before ordering; operation is rated from 0°C to 45°C.
SG300-52P provides a 375W PoE budget, while SG300-52MP provides 740W for the same powered-port count. Both models are discontinued. SG300-52P matches legacy installations with a lower aggregate power requirement; SG300-52MP matches existing configurations requiring the larger allocation, rather than serving as the current replacement for new deployments.
SG300-52P provides 52 network connections, while SG300-28PP provides 28 network connections. Both belong to the discontinued Small Business 300 family. SG300-52P matches a legacy installation needing the larger connection count; SG300-28PP matches a smaller existing configuration. This comparison addresses legacy matching rather than selection of a current-generation replacement.
C1300-48P-4G provides four dedicated 1G SFP uplinks, while SG300-52P provides two copper/SFP combo interfaces. The replacement chain passes through discontinued SG350-52P-K9-NA and CBS350-48P-4G-NA before reaching C1300-48P-4G. SG300-52P addresses legacy hardware matching; C1300-48P-4G addresses replacement purchases needing dedicated fiber uplinks.
