SF300-48PP-K9 provides 48 Fast Ethernet PoE+ access ports and four fixed Gigabit uplink connections for small-business networks. Two uplinks are dedicated copper ports; two are copper/SFP combo connections, with only one medium active on each combo connection. The Small Business 300 managed switch supports VLAN switching and configurable static IPv4 routing, corresponding to Layer 2+ capability. Its full-width chassis occupies one rack unit. The discontinued SRW248G4P-K9 predecessor provides PoE rather than PoE+, so endpoint power requirements distinguish the two configurations. Gigabit uplinks connect the access segment upstream but do not change the endpoint ports' 100 Mbps maximum.

17.6 Gbps switching capacity supports the fixed interface configuration, while 13.1 Mpps forwarding performance applies to 64-byte packets. Static IPv4 routing connects configured subnets without a dynamic routing protocol. SF300-48PP-K9 has 128 MB of DRAM and 16 MB of flash for its embedded software and configuration storage, alongside a 16000-entry MAC address table. Management includes a browser interface over HTTP or HTTPS, CLI access through the console, SSH or Telnet, and SNMP. Four speed-controlled fans provide active cooling rather than silent, fanless operation. The internal AC power supply powers the chassis independently of attached endpoints.
ORM Systems offers SF300-48PP-K9 new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links, PoE output under load on every powered port, optics bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify condition, quantity and delivery region on the purchase order. New equipment carries up to a 3-year extended ORM warranty, certified refurbished equipment carries up to a 1-year ORM warranty, and every condition includes 30-day returns with terms applying. Enterprise and volume orders support PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock and RMA across UK, EU, US and MEA.

When a voice endpoint rollout needs automatic interface configuration, Auto Smartport requires CDP or LLDP to be enabled and uses connected-device advertisements to configure ports. Compatible phones can learn the voice VLAN through those advertisements. Specify discovery settings and the intended voice VLAN before issuing the PO.
When replacement units must be staged before delivery, factory-default addressing requests DHCPv4 and adopts 192.168.1.254/24 after 60 seconds without a response. Duplicate fallback addresses require attention when staging multiple units together. Specify the management-addressing plan, staging connections and required quantities before the PO.
Gigabit connectivity at every endpoint
The access ports stop at 100 Mbps. C1300-48P-4G is the current migration endpoint with 48 Gigabit access ports and four 1G SFP uplinks.
Fanless operation in occupied rooms
Four speed-controlled fans cool the chassis, with 43.5 dB acoustic noise at 30°C. The switch is not fanless and requires an actively cooled installation.

SF300-48PP-K9 identifies a Cisco 300-family Fast Ethernet managed switch: 48 denotes its access-port count, and the PP configuration provides PoE+. The complete ordering identifier includes -K9. Specify the full PID rather than a shortened model name when identifying the required hardware configuration.
SF300-48PP-K9 supports a web interface over HTTP or HTTPS, CLI access through its console or remotely through SSH or Telnet, and SNMP management. Network management requires an accessible management IP address. Configure permitted access methods before connecting the switch to its operational network.
Yes, SF300-48PP-K9 reached end of sale on May 10, 2018, and Cisco support ended on May 31, 2023. The SF350 replacement and subsequent CBS350 replacement are also discontinued. The forward migration chain reaches C1300-48P-4G, which changes access connectivity from Fast Ethernet to Gigabit Ethernet.
ORM Systems offers SF300-48PP-K9 new sealed with up to a 3-year extended warranty, or certified refurbished with up to a 1-year warranty. Returns are available for 30 days on every condition; terms apply. Cisco's original limited lifetime hardware warranty ended with support on May 31, 2023.
SF300-48PP-K9 provides a shared 375W PoE budget across 48 powered access ports, with PoE+ supporting 30W per port until that budget is reached. The aggregate allocation must fit within the shared budget; connecting an endpoint to every powered port does not guarantee maximum power simultaneously.
SF300-48PP-K9 includes two dedicated Gigabit copper uplinks and two Gigabit copper/SFP combo uplinks. Each combo uplink uses either its RJ-45 connection or its SFP cage at one time. These are fixed interfaces, not a removable network-module bay, and their maximum Gigabit speed does not upgrade access-port speed.
The Small Business 300 switch can route IPv4 traffic between configured subnets when placed in Layer 3 system mode; its routing capability is static. Layer 2 mode instead provides VLAN-aware bridging. Changing system mode requires a reboot and removes the startup configuration, so preserve the configuration before changing modes.
Regional SF300-48PP-K9 variants replace SRW248G4P-K9-NA, SRW248G4P-K9-EU and SRW248G4P-K9-UK through their corresponding regional orders. Those older SF300-48P configurations provided PoE rather than PoE+. Match the regional ordering suffix when identifying the predecessor and retain the complete replacement identifier on the purchase order.
SF300-48PP-K9 supports PoE+, while SRW248G4P-K9 provides PoE; both configurations have a 375W shared power budget. Both are discontinued. The former addresses legacy replacement requirements involving higher per-port power, while the latter identifies an older PoE installation whose endpoint power class must be preserved or reassessed.
SF300-48PP-K9 provides 48 Fast Ethernet PoE+ access ports, while SF300-24PP-K9 provides 24. Both belong to the discontinued Small Business 300 family. The former matches higher-density legacy replacement requirements; the latter identifies a smaller installed configuration when maintaining an existing deployment rather than selecting a current-generation switch.
SF300-48PP-K9 has Fast Ethernet access ports, while C1300-48P-4G has Gigabit access ports. C1300-48P-4G is the current migration endpoint beyond the discontinued SF350 and CBS350 intermediates. The older switch fits exact legacy replacement requirements; the Catalyst model addresses buyers moving those endpoints to Gigabit connectivity.
No, the Small Business 300 48-port PoE+ switch uses four fans with speed control. SF300-48PP-K9 has a published acoustic level of 43.5 dB at 30°C. Account for active cooling and audible operation when locating the chassis, rather than treating the rack-mounted unit as silent desktop equipment.
