SF350-48 is a fanless Layer 2+ managed switch with 48 Fast Ethernet access ports for independently powered endpoints. Four fixed Gigabit uplinks combine two dedicated SFP interfaces with two copper/SFP combo interfaces; each shared interface uses only one medium at a time. The 1U rack-mount chassis belongs to the Cisco 350 Series Managed Switches family and serves small-business networks requiring configurable switching rather than unmanaged connectivity. The discontinued SF350-48P adds PoE+ for installations retaining Ethernet-powered devices. The non-PoE configuration here does not supply power to phones or access points, and its uplink architecture has no removable network-module bay.

17.6 Gbps switching capacity provides nonblocking forwarding across the installed interfaces. 13.09 Mpps forwarding supports wire-speed processing of 64-byte packets. Static IPv4 routing enables inter-VLAN forwarding, while PBR selects next hops using IPv4 or IPv6 ACLs. STP/RSTP/MSTP control Layer 2 loop behavior, and LACP combines configured links into aggregate connections. SF350-48 carries 512 MB of DRAM, 256 MB of flash, and a 3 MB packet buffer shared across its ports. Address learning uses a 16000-entry MAC table, separate from the routing limits of 990 static routes and 128 IP interfaces. Eight hardware queues support strict-priority or weighted round-robin scheduling; ingress policing and egress shaping apply rate controls to traffic policies. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection enforce address bindings at the edge. An RJ-45 console provides local administrative access, while the front-panel USB Type-A interface handles file and image transfers without occupying an Ethernet connection.
SF350-48 can be ordered new sealed or certified refurbished; specify condition, quantity, and the North American regional code SF350-48-K9-NA on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, and PSU status; firmware is verified and configurations are wiped to factory default. ORM warranties are up to a 3-year extended term for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement across the UK, EU, US, and MEA.

When several small-business sites require the same configuration baseline, text-editable configuration files and SCP autoconfiguration support preparation of a repeatable rollout. CLI privilege levels 1, 7, and 15 separate administrative access roles. Specify the configuration baseline, credential handling, and per-site staging quantities before releasing the purchase order.
When a maintenance lab needs packet captures before a replacement goes live, port mirroring supports eight source ports directed to one destination port in a single session. Keep the capture requirement separate from production connections, and specify analyzer connectivity, the capture session, and the staging configuration before ordering.
When a branch requires local address assignment, the embedded IPv4 DHCP server supports multiple pools and configurable DHCP options. Layer 2 DHCP relay also supports Option 82 for relaying client information. Define which device owns each address scope, then specify pool definitions, relay requirements, and the branch configuration before the PO.
Gigabit speed on every access port
SF350-48 access connections are limited to 10/100 Mbps. C1300-48T-4G provides 48 Gigabit access ports and four 1G SFP uplinks as the current migration model.
Power for phones and access points
SF350-48 does not deliver endpoint power over Ethernet. C1300-48P-4G is the current 48-port Gigabit PoE migration option, with four 1G SFP uplinks.
10G connectivity to upstream switches
SF350-48 uplinks are fixed at 1G, with no removable uplink-module bay for a 10G upgrade. A requirement for 10G upstream connections falls outside this hardware configuration.

SF350-48 identifies a Cisco 350 Series Fast Ethernet model with 48 non-PoE access ports. The SF350 segment identifies the Fast Ethernet family, while 48 gives the access-port count. Gigabit uplinks are included, and the North American regional ordering code is SF350-48-K9-NA.
Cisco 350 Series switches support browser HTTP/HTTPS, console CLI, SSH/Telnet CLI, SNMP, and embedded Smart Network Application management. Legacy integrations include FindIT Network Manager and Cisco Active Advisor. SNMP supports versions 1, 2c, and 3; the web UI offers simple and advanced configuration modes.
SF350-48 is discontinued; North American sales ended July 30, 2022, and Cisco support ends July 31, 2027. Software maintenance ended July 30, 2023. Its immediate replacement, CBS350-48T-4G-NA, is also discontinued; the migration chain now ends at C1300-48T-4G for a current-generation replacement purchase.
ORM Systems offers SF350-48 new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Every condition has 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is subject to eligibility, with Cisco service ending July 31, 2027 for North American units.
SF350-48 replaced SRW248G4-K9-NA, the discontinued SF300-48 regional order code. Other regional predecessors are SRW248G4-K9-AR, SRW248G4-K9-BR, SRW248G4-K9-CN, SRW248G4-K9-EU, and SRW248G4-K9-UK. SF350-48 is also discontinued, so a new-generation purchase should follow the migration chain to C1300-48T-4G rather than stopping at the discontinued CBS350-48T-4G-NA.
SF350-48 has four Gigabit uplinks: two dedicated SFP ports and two copper/SFP combo ports. Each combo port uses either its RJ-45 connector or its SFP cage, not both simultaneously. These uplinks are fixed, so adding a transceiver does not create a removable uplink-module bay.
Yes, SF350-48 supports static IPv4 routing between VLANs, with 990 static routes and 128 IP interfaces. PBR can steer traffic toward different next hops using IPv4 or IPv6 ACLs. Specify the routed interfaces and next-hop plan before ordering; this is static routed access rather than a dynamic-routing design.
SF350-48 uses an internal AC power supply accepting 100-240V AC at 50-60 Hz. Maximum system consumption is 24.2W. The fixed supply does not provide an internal redundant-PSU option, so specify the regional power cord and external power-protection requirements alongside the switch quantity on the purchase order.
No, the Cisco 350 Series does not provide hardware stacking for SF350-48. Smart Network Application supplies network-level discovery, monitoring, configuration, and firmware management across individual switches rather than combining their forwarding hardware. Orders for multiple units should retain separate device configurations and a physical inter-switch cabling plan.
SF350-48P supplies PoE+ with a shared 382W budget, while SF350-48 does not power endpoints over Ethernet. Both models have 48 Fast Ethernet access ports and are discontinued. SF350-48 suits like-for-like sparing for independently powered devices, while SF350-48P suits existing installations that require switch-supplied endpoint power.
SF350-48 has 48 Fast Ethernet access ports, while SF350-24 has 24. Both models are discontinued, and the difference is access-port density rather than a higher access speed. SF350-48 fits like-for-like replacement of a denser installation; SF350-24 fits maintaining an existing lower-port-count installation.
C1300-48T-4G has 48 Gigabit Ethernet access ports, while SF350-48 has 48 Fast Ethernet access ports. C1300-48T-4G is the current migration endpoint after the discontinued CBS350-48T-4G-NA. SF350-48 serves existing 10/100 installations; C1300-48T-4G suits a migration requiring Gigabit speed on every access connection.
