SF350-48P-K9 provides 48 10/100 Mbps PoE+ access ports for small-business endpoints that do not require Gigabit desktop connections. This managed Layer 2+ switch combines fixed Gigabit uplinks with a 1U rack-mount chassis in the Cisco 350 Series. Two dedicated SFP slots and two copper/SFP combo interfaces provide the uplink choices; each combo interface uses either its copper connector or its SFP cage. IP phones, wireless access points and other compatible powered devices connect through the access ports, with power drawn from a shared allocation. The discontinued SF350-48MP-K9 sibling increases the PoE budget to 740W. This 48-port Fast Ethernet PoE+ switch separates endpoint connectivity from faster upstream connections, so the purchase specification should distinguish access speed from uplink speed.

17.6 Gbps switching capacity provides nonblocking forwarding across the installed interfaces. 13.09 Mpps forwarding at 64-byte packet size describes small-packet handling rather than uplink speed. 382W of shared PoE power sets the allocation limit for connected powered devices. Static IPv4 and IPv6 routing support communication between local network segments, with 990 IPv4 static routes and 128 IP interfaces; PBR directs matching traffic to selected next hops. SF350-48P-K9 has 512 MB of DRAM and 256 MB of flash for operating software and configuration storage. A 3 MB packet buffer is dynamically shared across ports to absorb traffic bursts. The Cisco Small Business switch supports STP, RSTP and MSTP for loop control, while LACP combines eligible links into aggregation groups. Browser-based configuration and a scriptable CLI provide administration. Three fans cool the internal AC-powered hardware.
Specify SF350-48P-K9 as new sealed or certified refurbished, and state condition and quantity on the purchase order. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. New units carry up to a 3-year extended ORM warranty; certified refurbished units carry up to 1 year, and every condition has 30-day returns, terms apply; Cisco's limited lifetime hardware warranty ends January 31, 2028, subject to eligibility. ORM Systems accepts volume POs, offers Net-30 for government and provides RMA with advance replacement across UK, EU, US and MEA.

An endpoint refresh that includes higher-draw devices needs a port-by-port power schedule. Eight selected access ports support 60W PoE, while other powered access ports support 30W. Record each device's negotiated requirement and simultaneous startup demand, then specify its intended port assignment before the purchase order.
A repeat branch purchase requires the correct regional electrical configuration rather than only the base product identifier. SF350-48P-K9-NA is the North American ordering variant. Keep each site's power-cord region and quantity on the same purchase order, and confirm the regional suffix before approving a multisite release.
A staging program that loads a common configuration across several units can use text-editable configuration files and secure file transfer. The front-panel USB Type-A slot also supports image and configuration handling. Specify the staging baseline, configuration ownership and required console access before releasing the equipment purchase order.
Gigabit connectivity for every endpoint
SF350-48P-K9 access ports are limited to 10/100 Mbps. C1300-48P-4G provides 48 Gigabit access ports and is the current migration option for endpoint connections requiring 1G.
Fanless operation in occupied rooms
SF350-48P-K9 uses three cooling fans, with acoustic noise of 42.5 dB at 0°C to 25°C and 55 dB at 50°C. Fanless operation is unavailable.

SF350-48P-K9 identifies the SF350 Fast Ethernet managed switch with 48 PoE+ access ports and fixed Gigabit uplinks. SF350 names the switch family, 48 is the access-port count, and P identifies the powered model. North American orders use the regional identifier SF350-48P-K9-NA.
The Cisco 350 Series is managed through HTTP/HTTPS web interfaces, console CLI, SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager, FindIT Network Discovery Utility and Cisco Active Advisor. Browser configuration provides simple and advanced modes, while the CLI supports scripting. Choose the administration method and access credentials before configuration staging.
SF350-48P-K9 North American models are discontinued, with end-of-sale on January 29, 2023 and last support on January 31, 2028. Software maintenance ended January 29, 2024. The direct replacement CBS350-48P-4G-NA also reached end-of-sale on October 29, 2024; the current migration endpoint is C1300-48P-4G.
ORM Systems offers SF350-48P-K9 new sealed or certified refurbished. ORM warranties are up to a 3-year extended term for new units and up to 1 year for refurbished units. Every condition has 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is subject to eligibility and ends January 31, 2028.
SF350-48P-K9 replaces the discontinued SF300-48PP-K9-AU, SF300-48PP-K9-BR, SF300-48PP-K9-EU, SF300-48PP-K9-NA and SF300-48PP-K9-UK variants, whose end-of-sale date was May 10, 2018. Regional replacement suffixes match the older units' ordering regions. For a current-generation purchase, the migration chain continues to C1300-48P-4G rather than stopping at this discontinued model.
SF350-48P-K9 offers a shared 382W PoE budget across 48 powered access ports, with eight selected ports supporting 60W and the remaining powered access ports supporting 30W. These are per-port limits, not simultaneous full-load guarantees. Add the devices' concurrent requirements before assigning the powered-port schedule.
The Cisco 350 Series supports MGBSX1 for 1G multimode links to 500 m and MGBLX1 for 1G single-mode links to 10 km. SF350-48P-K9 uses fixed SFP cages, including two shared copper/SFP interfaces. Order compatible optics separately and match the fiber type to the installed link.
No, SF350-48P-K9 cannot form a hardware stack; network-level monitoring and management do not combine its forwarding hardware into one stacked switch. Smart Network Application can discover and manage multiple switches. Treat each unit as an independently configured device when preparing replacement quantities and management addressing.
Yes, SF350-48P-K9 supports static IPv4 and IPv6 routing between network segments, including VLAN interfaces. The IPv4 scale is 990 static routes with 128 IP interfaces. PBR can select next hops using IPv4 or IPv6 access control rules, so define the route plan before ordering.
SF350-48P-K9 uses an internal AC power supply accepting 100-240V AC at 50-60 Hz, without a redundant supply option. Maximum input consumption with PoE is 464.3W at 110V. Size the power feed and UPS for the maximum loaded value, not merely the power allocated to connected devices.
SF350-48MP-K9 has a 740W PoE budget, compared with 382W on SF350-48P-K9. Both are discontinued models, so this comparison concerns existing installations and replacement spares. SF350-48P-K9 suits device schedules within its lower allocation; SF350-48MP-K9 suits otherwise comparable installations needing the larger shared budget.
SF350-24P-K9 has 24 Fast Ethernet access ports, while SF350-48P-K9 has 48. Both models are discontinued; neither comparison changes the fixed access-speed class. The smaller model fits an existing 24-port replacement requirement, while the 48-port model fits a higher-density legacy port plan.
C1300-48P-4G provides 48 Gigabit Ethernet access ports, while SF350-48P-K9 provides 48 Fast Ethernet access ports. The migration chain passes through the discontinued CBS350-48P-4G-NA. SF350-48P-K9 is for maintaining a matching legacy installation; C1300-48P-4G is the current migration model for buyers requiring Gigabit endpoint connections.
