SF300-48PP-K9-UK is a managed Layer 2+ switch with 48 10/100 PoE+ access ports and four fixed Gigabit uplinks for small-business networks. Two uplinks are dedicated copper ports, while two are copper/SFP combo connections, allowing the handoff medium to match the installed cabling. The 1U rack-mount chassis serves powered endpoints where Fast Ethernet access remains an explicit requirement. SF300-48PP combines endpoint switching with VLAN separation rather than operating as an unmanaged port expander. The discontinued SRW248G4P-K9-UK uses the earlier PoE class instead of PoE+. Buyers retaining an existing access design should distinguish the required endpoint data rate from the uplink rate before choosing this hardware; Gigabit uplinks do not make its access connections Gigabit Ethernet.

17.6 Gbps switching capacity carries traffic across the built-in interfaces, while 13.1 Mpps forwarding performance applies to 64-byte packets. 375W of shared PoE power must be allocated across connected endpoints rather than treated as a full-power allowance for every port. Static IPv4 routing handles inter-VLAN communication without dynamic route exchange. SF300-48PP-K9-UK uses 128 MB of DRAM for operation and 16 MB of flash for onboard software storage. A 16000-entry MAC table accommodates learned endpoint addresses, while four hardware queues provide traffic-priority handling within the Cisco 300 Series. Rate limiting and 512 access-control rules provide additional traffic controls; DHCP snooping, IP Source Guard and Dynamic ARP Inspection address endpoint-facing security requirements. 421.36W worst-case input consumption, including PoE, provides the maximum published figure for AC and UPS provisioning. Four speed-controlled fans provide active cooling, and the operating range extends from 0°C to 50°C.
ORM Systems offers SF300-48PP-K9-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port. ORM warranties are up to 3-year extended for new units and up to 1 year for certified refurbished units; both conditions include 30-day returns, terms apply. Cisco's former Limited Lifetime coverage ended with Cisco service on May 31, 2023, so specify condition and quantities before submitting the order. For enterprise and volume orders, PO acceptance, Net-30 for government and RMA with advance replacement are available.

When maintaining an installation built around SRW248G4P-K9-UK, this model provides the later PoE+ replacement within the same managed-switch family. An existing configuration still needs review rather than an assumption of identical behavior. Before the PO, verify endpoint requirements, uplink media and the configuration intended for the replacement.
When adding powered connections across an existing branch, copper-run length remains a deployment constraint: connected network devices must stay within the 100-meter cabling limit. Review patch leads together with permanent cabling rather than measuring the horizontal run alone. Confirm the complete cable schedule before specifying switch quantities and installation locations.
When a distributed estate needs a common spare-order process, ORM provides regional stock and RMA handling across the UK, EU, US and MEA. Keep spare quantities and destination requirements explicit instead of treating each local request independently. Specify the required condition and regional handling arrangements on the consolidated purchase order.
Gigabit connectivity at every endpoint
Access ports stop at 100 Mbps. C1300-48P-4G is the current migration option with 48 Gigabit Ethernet access ports for endpoints requiring higher data rates.
10G uplinks to distribution
The fixed uplinks operate at Gigabit Ethernet speed. No removable uplink-card bay provides an upgrade path to 10G connections on this chassis.
Fanless operation in occupied rooms
Four speed-controlled fans provide cooling rather than silent operation. Published acoustic levels reach 43.5 dB at 30°C and 54.1 dB at 40°C.

SF300-48PP-K9-UK identifies a Cisco 300 Series managed switch with 48 10/100 PoE+ ports and Gigabit uplinks. SF300 names the Fast Ethernet model family, 48 identifies access-port density, and PP distinguishes the PoE+ version. K9-UK completes the order identifier and should remain intact when matching a purchase order.
SF300-48PP-K9-UK supports a web interface over HTTP or HTTPS, CLI access through the serial console, SSH or Telnet, and SNMPv1, SNMPv2c and SNMPv3 management. RMON supplies monitoring functions. Specify the intended management method during staging so access credentials and monitoring settings match the operational handover.
SF300-48PP-K9-UK reached end of sale on May 10, 2018, and Cisco support ended May 31, 2023. SF350-48P-K9-UK, its original replacement, is also discontinued. The later migration chain reaches C1300-48P-4G, which changes endpoint connectivity from Fast Ethernet to Gigabit Ethernet rather than preserving the original access speed.
ORM Systems offers SF300-48PP-K9-UK new sealed with up to 3-year extended warranty or certified refurbished with up to 1-year warranty. Both conditions have 30-day returns; terms apply. Cisco's original Limited Lifetime hardware warranty is no longer active for this model: Cisco service ended May 31, 2023.
SF300-48PP-K9-UK replaces SRW248G4P-K9-UK, the earlier SF300-48P managed PoE switch with Gigabit uplinks. The replacement introduces PoE+ while retaining the 48-port Fast Ethernet access arrangement. For an installed-base spare, verify endpoint power requirements and configuration separately instead of assuming the earlier unit and its replacement are interchangeable in every operational detail.
No, SF300-48PP-K9-UK shares a 375W budget across its powered ports, although an individual PoE+ port supports 30W. A simultaneous 48-port load at 30W would require 1440W. Size the connected endpoint schedule against the shared allowance rather than multiplying the per-port maximum into an assumed available budget.
SF300-48PP-K9-UK has four Gigabit uplinks: two dedicated copper ports and two copper/SFP combo ports. A combo connection uses one medium at a time. MGBSX1 provides a 1000BASE-SX multimode fiber option. Specify compatible optics separately and match the fiber type and optical connection at the far end.
Yes, SF300-48PP-K9-UK supports static IPv4 routing between VLANs rather than dynamic route exchange. Its routing capability accompanies managed switching, so the intended VLAN interfaces and static paths need configuration. Confirm the routing design before ordering rather than treating the switch as either an unmanaged device or a dynamic-routing replacement.
SF300-48PP occupies 1U and measures 440 mm wide, 350 mm deep and 44.45 mm high, with a weight of 5.44 kg. Rack-mount hardware is included with the standard configuration. Allow additional installation clearance for connected cables and active cooling rather than treating the bare chassis depth as the complete installed envelope.
SF300-48PP-K9-UK supports PoE+, whereas SRW248G4P-K9-UK supplies the earlier PoE class. Both are discontinued 48-port Fast Ethernet models with Gigabit uplinks. The earlier identifier corresponds to PoE-only installed-base requirements; the PP model addresses legacy spare requirements that explicitly call for the later PoE+ powered-port capability.
SF300-48PP-K9-UK provides 48 access ports, while SF300-24PP-K9 provides 24. Both are managed Fast Ethernet PoE+ models in the retired 300 family. Compare the existing patch-panel count and required endpoint connections: the 48-port unit corresponds to denser legacy layouts, while the 24-port unit corresponds to smaller connection requirements.
C1300-48P-4G provides Gigabit Ethernet access ports, whereas SF300-48PP-K9-UK limits access connections to 10/100. The current model addresses endpoint requirements that exceed Fast Ethernet speed. The older switch remains an installed-base spare option where retaining the existing access-interface specification is required rather than upgrading endpoint connectivity.
The Small Business 300 series supports four hardware queues, traffic rate limiting and up to 512 access-control rules. DHCP snooping, IP Source Guard and Dynamic ARP Inspection add endpoint-facing controls. Specify the required classification, filtering and trusted-uplink settings in the configuration plan rather than treating the unit as an unmanaged switch.
