SF300-48PP-K9-NA is a managed Layer 2+ switch with 48 Fast Ethernet PoE+ access ports and four fixed Gigabit uplink connections: two dedicated copper ports and two copper/SFP combo ports. The rack-mount chassis belongs to the Cisco 300 Series and serves small-business networks connecting powered phones, wireless access points and other Ethernet endpoints. Copper and fiber share each combo connection, so the uplink plan must select one medium per pair. Unlike the discontinued SRW248G4P-K9-NA, which provides PoE, this model supports PoE+ endpoint power. Its access connections remain limited to 100 Mbps; the faster uplinks connect the switch upstream rather than increase individual endpoint speed.

17.6 Gbps switching capacity supports simultaneous traffic across the access and uplink interfaces, while 13.1 Mpps forwarding performance describes handling of minimum-size packets. 375W of shared PoE power requires an endpoint allocation rather than unrestricted maximum output across the entire powered port bank. Static IPv4 routing supports communication between local subnets without adding a dynamic routing protocol. SF300-48PP-K9-NA carries 128 MB of memory and 16 MB of flash for its embedded software and configuration. Administrators can separate traffic with VLANs, apply access control lists and prioritize traffic through QoS. STP, RSTP and MSTP handle spanning-tree operation, while LACP groups compatible Ethernet links. The SF300-48PP also supports port mirroring and syslog for troubleshooting. These controls support a managed access deployment, but dynamic routing is not part of its routing feature set.
Order SF300-48PP-K9-NA in new sealed or certified refurbished condition, and specify the required quantity and condition on the purchase order. Certified refurbished units are inspected and bench-tested, with every port linked at rated speed, PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. ORM provides up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on every condition; terms apply. Cisco coverage ended May 31, 2023. For enterprise and volume orders, PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US and MEA are available.

A subnet redesign that keeps routing close to local endpoints can use the switch's 128 IP interfaces. Before committing the purchase, map the required physical, VLAN and link aggregation interfaces, and confirm that the planned topology uses static routing rather than requiring dynamic route exchange.
A maintenance purchase replacing SRW248G4P-K9-NA hardware starts from a predecessor that left Cisco sale on April 27, 2015. Treat the replacement as a hardware change rather than an identical spare: compare the saved configuration, endpoint power requirements and installed uplink media before specifying the purchase order.
A coordinated replacement across offices can use text-editable configuration files and scriptable CLI access to prepare common settings before shipment. CLI privilege levels 1, 7 and 15 allow different administrative permissions. Validate the master configuration on a staging unit and specify the required configuration handling before the purchase order.
Gigabit connections for every endpoint
Access ports stop at 100 Mbps, so Gigabit uplinks do not provide Gigabit endpoint connections. C1300-48P-4G is the current successor with 48 Gigabit access ports.
Silent fanless operation
Four speed-controlled fans cool the chassis, with acoustic output reaching 54.1 dB at 40°C. A requirement for fanless operation excludes this model.

SF300-48PP-K9-NA identifies the Cisco Small Business 300 managed Fast Ethernet model with 48 powered access ports; PP distinguishes its PoE+ configuration. The full ordering identifier includes K9-NA. Retain the complete part number on the purchase order rather than substituting the shorter SF300-48PP model name.
SF300-48PP-K9-NA supports a browser interface over HTTP or HTTPS, console access, CLI over SSH or Telnet, and SNMP versions 1, 2c and 3. Full and menu-based CLI options are available. Its original management integrations also included Cisco Small Business FindIT Network and Cisco OnPlus.
SF300-48PP-K9-NA provides a shared 375W PoE budget across 48 powered ports, with a 30W maximum on an individual PoE+ port. The aggregate budget prevents every port from delivering its individual maximum simultaneously. Add the planned simultaneous endpoint demand before deciding how many powered devices to connect.
SF300-48PP-K9-NA has two dedicated Gigabit copper uplinks and two Gigabit copper/SFP combo uplinks. Each combo pair operates through its copper connector or SFP cage, not both simultaneously. Supported Gigabit fiber options include MGBSX1 for multimode fiber and MGBLX1 for single-mode fiber; match the optic to the installed fiber.
The Small Business 300 switch supports static IPv4 routing between VLANs, with 512 static routes and 128 IP interfaces. This provides local subnet routing without a dynamic routing protocol. Before using the switch as a subnet gateway, confirm that its static route model matches the required network topology.
SF300-48PP-K9-NA is discontinued: Cisco sale ended May 10, 2018, and support ended May 31, 2023. Its immediate replacement, SF350-48P-K9-NA, and the subsequent CBS350-48P-4G-NA are also discontinued. The replacement chain now reaches C1300-48P-4G, which changes the access connections from Fast Ethernet to Gigabit Ethernet.
SF300-48PP-K9-NA replaces SRW248G4P-K9-NA, the earlier SF300-48P ordering identifier. The predecessor reached end of sale on April 27, 2015. For a legacy maintenance order, identify the complete existing part number and review the saved configuration rather than assuming the similar model names describe identical endpoint power capabilities.
SF300-48PP-K9-NA supports PoE+, whereas SRW248G4P-K9-NA provides PoE on its access ports. Both are discontinued, so this comparison concerns legacy inventory rather than a current-product recommendation. The PoE+ model addresses endpoints requiring the higher individual power class; the predecessor corresponds to an existing PoE-only hardware requirement.
SF300-48PP-K9-NA has 48 Fast Ethernet access ports, while SF300-24PP-K9 has 24. Both belong to the retired Small Business 300 family. For legacy sparing, the larger model corresponds to a higher connection count; the smaller model corresponds to installations retaining the lower access-port density.
SF300-48PP-K9-NA has 100 Mbps access ports, while C1300-48P-4G provides 48 Gigabit access ports. The former is discontinued, and the latter is the current successor reached through its replacement chain. Retaining the older model is a legacy-sparing decision; the successor addresses purchases requiring Gigabit endpoint connections.
ORM Systems offers SF300-48PP-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Every condition has 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty ended May 31, 2023, and Cisco service has ended.
