SG300-52MP-K9-UK is a managed Layer 2+ access switch with 48 Gigabit PoE+ access ports, two dedicated Gigabit copper uplinks, and two Gigabit combo uplinks. Each combo connection offers either copper or SFP fiber connectivity, with one medium active at a time. The 1U rack-mount chassis belongs to the Cisco Small Business 300 family and connects powered endpoints such as IP phones and wireless access points. Voice VLAN support separates telephone traffic from ordinary data, while guest VLAN support provides a separate segment for visitor connections. The discontinued SG300-52P-K9 has a smaller 375W PoE budget. The SG300-52MP configuration retains fixed uplinks rather than a removable uplink-card architecture.

104 Gbps switching capacity supports non-blocking forwarding across the fixed interfaces. 77.38 Mpps forwarding performance describes handling of 64-byte packets. 740W of shared PoE power requires allocation across connected endpoints rather than maximum-power operation on every powered port. Static IPv4 routing supports configured paths between local subnets, with a ceiling of 512 routes. SG300-52MP-K9-UK carries 128 MB of DRAM and 16 MB of flash for its operating software and configuration. The Cisco 300 Series combines STP/RSTP/MSTP loop control with LACP link aggregation. A 16384-entry MAC table accommodates learned endpoint addresses, while four hardware queues provide traffic-priority separation. Browser management and Textview CLI provide graphical and text-based administration. Dual firmware images retain separate software images for maintenance and recovery work. 873.05W maximum consumption at 110V provides the upper input-power figure for UPS sizing; the corresponding maximum at 220V is 843.57W. Four fans provide active chassis cooling.

When several locations need the same configuration, text-editable configuration files and SCP downloads allow a common starting file to be applied to each unit. Textview CLI privilege levels 1, 7, and 15 separate administrative access. Specify the configuration template, local addressing changes, and operator privileges before issuing the purchase order.
When subnet boundaries must remain on the access switch, the switch supports up to 128 IP interfaces across physical ports, link aggregation groups, VLAN interfaces, and loopback interfaces. Map the required interface assignments against the addressing plan during staging, then confirm that the intended configuration fits before releasing the equipment purchase order.
When a replacement must be validated before entering an existing network, port mirroring can send traffic from eight source ports to one destination port in a single session. A network analyzer receives the mirrored traffic for inspection. Reserve the analyzer connection and define the traffic sources in the acceptance plan before ordering.
10G uplinks to distribution
The fixed uplinks are limited to 1G, and installing a transceiver does not create a faster uplink. A deployment requiring 10G distribution connections needs different switching hardware.
Dynamic routing between network segments
IPv4 forwarding uses static routes rather than dynamic route exchange. Networks requiring automatically learned routes need a different routing-capable switch or an upstream router.
Active Cisco service coverage
Cisco service ended October 31, 2023, so this model cannot meet an active manufacturer-support requirement. C1300-48FP-4G is the current migration endpoint, with four dedicated 1G SFP uplinks.

SG300-52MP-K9-UK identifies a Cisco Small Business 300 managed Gigabit Max-PoE switch. SG300 identifies the Gigabit managed switch series, 52 denotes the total system port count, and MP identifies the Max-PoE configuration. The complete K9-UK ordering form should remain intact on the purchase order to identify this exact item.
Cisco Small Business 300 switches provide an HTTP/HTTPS web interface, Textview CLI through the serial console or SSH/Telnet, and SNMP versions 1, 2, and 3. Full command-line and menu-based interfaces are available. The built-in web dashboard supports configuration, monitoring, and system maintenance; legacy integrations include FindIT Network Discovery and Cisco OnPlus.
SG300-52MP-K9-UK provides a shared 740W PoE budget across 48 powered ports, with a maximum of 30W on an individual PoE+ port. Forty-eight ports at 30W would require 1440W, exceeding the available budget. Endpoint power allocations therefore need to fit the shared total rather than every port drawing its maximum simultaneously.
SG300-52MP-K9-UK has two dedicated 1G copper uplinks and two 1G combo uplinks that select either RJ-45 copper or SFP fiber. MGBSX1 supports multimode fiber, while MGBLX1 supports single-mode fiber. Optics are ordered separately, and using an SFP disables the paired copper connection rather than adding another simultaneous port.
No, SG300-52MP-K9-UK does not form a hardware stack. Each chassis remains a standalone switch with its own configuration. LACP can aggregate Ethernet connections, but aggregated links do not combine chassis into a shared switching system. Additional switches therefore remain separate managed devices rather than members of a hardware stack.
SG300-52MP-K9-UK supports static IPv4 routing with up to 512 static routes and 128 IP interfaces. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. The routing capability serves explicitly configured subnet paths; it does not provide dynamic route exchange between neighboring routing devices.
No, SG300-52MP-K9-UK uses a single internal AC power supply rather than redundant power modules. Input voltage is 100-240V AC at 50-60 Hz. Maximum consumption including PoE is 873.05W at 110V or 843.57W at 220V, so the electrical feed and UPS allocation must account for the selected input conditions.
The SG300-52MP occupies one rack unit and measures 440 mm wide, 44.45 mm high, and 350 mm deep. Weight is 5.32 kg, and a mounting kit is included. Four fans provide active cooling, so the installation is not fanless and the rack layout must accommodate chassis ventilation.
Yes, SG300-52MP-K9-UK ended sale on October 4, 2018, and Cisco service ended October 31, 2023. Its initial replacement, SG350-52MP-K9-UK, is also discontinued. The subsequent CBS350-48FP-4G-UK is discontinued as well, and the replacement chain now reaches C1300-48FP-4G. Retaining the original switch requires support independent of Cisco service.
ORM offers SG300-52MP-K9-UK new sealed with up to a 3-year extended warranty, or certified refurbished with up to a 1-year warranty. Both conditions include 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on October 31, 2023. Refurbished units are inspected and bench-tested.
A 740W versus 375W shared PoE budget distinguishes SG300-52MP-K9-UK from the discontinued SG300-52P-K9. Both provide 48 powered ports, so the larger budget changes power allocation rather than endpoint count. The Max-PoE model suits a higher combined device allocation; the 52P variant serves lower-power legacy installations.
SG300-52MP-K9-UK provides 48 powered access ports, while the discontinued SG300-28MP-K9 provides 24 powered access ports. This difference concerns powered endpoint density rather than an uplink-speed change. The higher-density model suits more powered connections in one rack position; the 28-port model serves smaller legacy endpoint groups.
C1300-48FP-4G has four dedicated 1G SFP uplinks, whereas SG300-52MP-K9-UK uses two dedicated copper uplinks and two copper/SFP combo uplinks. The current C1300-48FP-4G suits buyers assigning four fiber uplinks. The discontinued SG300-52MP-K9-UK suits legacy retention plans that preserve its mixed copper and shared-medium uplink arrangement.
