SF350-48MP-K9 is a Layer 2+ managed switch with 48 Fast Ethernet PoE+ access ports and four fixed Gigabit uplink connections in a 1U rack-mount chassis. Two dedicated SFP slots and two copper/SFP combo connections provide the uplink architecture, with each combo connection using either copper or fiber at a time. The Cisco 350 Series configuration serves small-business voice, wireless, and IP surveillance endpoints whose wired connections fit 10/100 Mbps access speeds. Compared with the discontinued SF350-48P-K9 and its 382W endpoint power allocation, this model carries the higher-power configuration. Within the Cisco Small Business family, the fixed chassis combines powered endpoint connectivity with local configuration and network segmentation rather than removable uplink cards.

17.6 Gbps switching capacity provides nonblocking switching across the installed interfaces. 13.09 Mpps forwarding performance applies to 64-byte packets, separating packet-processing throughput from link bandwidth. 740W of shared PoE power must cover the combined allocation to powered endpoints rather than every port’s maximum simultaneously. 990 static IPv4 routes and 128 IP interfaces support configured paths between network segments; dynamic routing is not part of this configuration. SF350-48MP-K9 uses 512 MB of DRAM and 256 MB of flash for control software and configuration storage. A 3 MB packet buffer is dynamically shared across ports. STP/RSTP/MSTP handle spanning-tree operation, while LACP supports aggregated connections. Browser configuration, CLI access, SNMP, and FindIT Network Manager provide local and network-level administration. 866.7W worst-case consumption with PoE establishes the load to allow for when sizing upstream power and backup capacity. Four fans cool the chassis, and the operating range extends from 0°C to 50°C, requiring ventilation appropriate to the installed environment.
ORM Systems offers SF350-48MP-K9 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units; returns are 30 days on either condition, terms apply. 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. Specify condition, quantity, and required optics on the purchase order; Cisco's limited lifetime hardware warranty is bounded by July 31, 2027, when Cisco service ends. POs are accepted, government orders qualify for Net-30, and enterprise or volume purchasing includes RMA with advance replacement across UK, EU, US, and MEA regional stock and RMA operations.

When a branch adds IP phones alongside guest devices, automatic voice VLAN assignment and private VLAN edge isolation separate endpoint roles. Combine 802.1X authentication with the planned voice policy, then specify phone discovery settings and the upstream voice VLAN configuration before releasing the purchase order.
When several offices need repeatable configurations, editable configuration files and scriptable CLI access provide a common staging workflow. CLI privilege levels 1, 7, and 15 separate administrative access. Define the approved configuration file, administrator permissions, and secure transfer method before ordering the site quantities.
When an existing installation retains a long-distance single-mode fiber connection, MGBLH1 provides Gigabit connectivity over distances reaching 40 km. The optic must match the installed fiber and the equipment at the opposite end. Specify MGBLH1, compatible fiber cabling, and the remote-end connection before issuing the purchase order.
Gigabit speeds for every endpoint
SF350-48MP-K9 limits access connections to 100 Mbps. The current replacement, C1300-48FP-4G, provides 48 Gigabit Ethernet access ports while retaining the same endpoint connection count.
10G uplinks to distribution
SF350-48MP-K9 provides fixed Gigabit uplinks, not 10G interfaces. Installing a different transceiver cannot turn these SFP cages into 10G uplink ports.

SF350-48MP-K9 identifies a 350 Series Fast Ethernet managed switch with 48 PoE+ access ports and a 740W shared power budget. SF350 identifies the series and access-speed family; 48 identifies the access-port count; MP distinguishes the higher-power configuration. The K9 suffix remains part of the complete manufacturer ordering identifier when specifying the unit.
The Cisco 350 Series supports an HTTP/HTTPS web interface, full or menu-based CLI over console, SSH or Telnet, SNMP versions 1, 2c and 3, Smart Network Application, and FindIT Network Manager with an embedded Probe. Cisco Active Advisor and Network Plug and Play provide additional network-level services and provisioning paths.
SF350-48MP-K9 is discontinued: North American end of sale was July 30, 2022, and the last date of support is July 31, 2027. The immediate replacement, CBS350-48FP-4G-NA, is also discontinued. The current replacement chain ends at C1300-48FP-4G, which changes endpoint connections from Fast Ethernet to Gigabit Ethernet.
SF350-48MP-K9 is offered new sealed or certified refurbished. ORM provides up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days for either condition; terms apply. Cisco's limited lifetime hardware warranty is bounded by July 31, 2027, when Cisco service ends.
SF350-48MP-K9 shares 740W across 48 PoE+ ports, with eight ports supporting 60W PoE and the other powered ports supporting 30W maximum. The shared budget limits simultaneous allocation, so port count does not guarantee maximum power everywhere. Confirm each endpoint's demand and high-power compatibility before assigning the eight 60W-capable ports.
The SF350-48MP configuration has four Gigabit uplink connections: two dedicated SFP slots and two copper/SFP combo ports. Each combo connection allows only one medium at a time. MGBSX1 supports multimode fiber, while MGBLX1 provides single-mode connectivity; specify compatible optics separately from the switch and match the equipment at the opposite end.
Yes, SF350-48MP-K9 supports static IPv4 routing between configured network interfaces, with 990 static routes and 128 IP interfaces available. Layer 3 interfaces can be assigned to physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. Specify the required static route entries and interface assignments before staging the switch.
The SF350-48MP configuration requires 1U of rack space and measures 440 mm wide, 44 mm high, and 350 mm deep, with a weight of 5.61 kg. A mounting kit accompanies the base package. Confirm rack depth, cable clearance, and mounting hardware for the selected condition before issuing the purchase order.
SF350-48MP-K9 uses an internal 100-240V AC power supply rather than an external adapter or PoE-powered uplink. The configuration does not provide an internal redundant PSU option. Worst-case consumption including PoE is 866.7W at 110V, so upstream power and backup capacity must account for the complete powered load.
SF350-48MP-K9 provides 740W of shared PoE power, while the discontinued SF350-48P-K9 provides 382W. Both carry 48 Fast Ethernet PoE+ access ports, making aggregate endpoint power the distinguishing specification. The MP configuration fits higher combined endpoint demand; the P variant is a lower-budget reference for existing installations with the same connection count.
SF350-48MP-K9 provides 48 Fast Ethernet access ports, while the discontinued SF350-24MP-K9 provides 24. Both remain Fast Ethernet models, so the density difference does not introduce Gigabit endpoint speeds. A 48-port requirement fits the former; the 24-port configuration matches fewer endpoint connections in existing installations.
C1300-48FP-4G provides 48 Gigabit Ethernet access ports, whereas SF350-48MP-K9 provides 48 Fast Ethernet access ports. C1300-48FP-4G is the current endpoint of the replacement chain, beyond the discontinued CBS350 intermediate. The older model serves same-model sparing; C1300-48FP-4G suits a refresh that requires Gigabit connections at the endpoints.
