SRW248G4-K9-NA is a fanless, managed access switch with 48 Fast Ethernet downlinks for 10/100 Mbps endpoints and four fixed Gigabit uplink connections. Two uplinks are dedicated copper ports; two are copper/SFP combo connections, with one medium active on each pair. The Layer 2+ design fits rack-based small-business installations without requiring a separate uplink card. The Cisco SF300-48 belongs to the Small Business 300 family and connects separately powered desktops, printers, and other wired equipment rather than supplying endpoint power. The discontinued SRW248G4P-K9-NA adds PoE to the corresponding access configuration. Copper and fiber connectivity are available through the built-in uplink interfaces, allowing the purchase configuration to follow the existing cabling and upstream connection requirements.

17.6 Gbps switching capacity supports aggregate traffic across the access and uplink connections. 13.1 Mpps forwarding throughput applies to 64-byte packets, making packet size relevant when assessing traffic requirements. Static IPv4 routing provides local subnet connectivity rather than a dynamic routing control plane. SRW248G4-K9-NA carries 128 MB of DRAM and 16 MB of flash for its embedded software and configuration storage. An 8000-entry MAC table bounds learned-address capacity. STP, RSTP, and MSTP provide loop-control choices, while LACP groups suitable links. Browser-based HTTP/HTTPS access, a console CLI, SSH/Telnet, and SNMP provide administration and monitoring paths. Four hardware queues support strict-priority or weighted round-robin scheduling. The internal AC input accepts 100–240V, while 29.2W maximum consumption provides an equipment-load allowance for power planning. Operating conditions span 0°C to 40°C, and the fixed internal supply does not provide a second PSU bay.
ORM Systems offers SRW248G4-K9-NA new sealed or certified refurbished; 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, with firmware verified and configurations wiped to factory default. Specify the required condition, quantity, and fiber accessories on the purchase order. ORM warranties provide 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; Cisco service and warranty ended August 31, 2023. POs are accepted, government buyers receive Net-30 terms, and enterprise or volume orders can include RMA with advance replacement across UK, EU, US, and MEA stock/RMA regions.

When several branch switches need the same baseline, text-editable configuration files and DHCP Options 66 and 67 support repeatable staging. The 300 Series accepts configuration downloads instead of requiring every setting to be entered separately. Define the approved configuration file, addressing requirements, and staging method before issuing the purchase order.
When reproducing a fault before replacing installed equipment, port mirroring can send traffic from eight source ports to one destination in a single session. Dual firmware images support staged maintenance work. Include the required test-unit quantity and define the intended firmware baseline before the purchase order is released.
Gigabit connections for every desktop
The 48 access ports stop at 100 Mbps. C1300-48T-4G is the current migration endpoint with 48 Gigabit access ports and four 1G SFP uplinks.
Ethernet power for connected endpoints
SRW248G4-K9-NA supplies data only and has no PoE output. Phones, cameras, and access points require separate power equipment rather than power from these Ethernet ports.
Native 10G uplink connections
The built-in uplinks are limited to Gigabit Ethernet, and the chassis has no removable uplink-card bay. A 10G uplink requirement needs different switching hardware.

SRW248G4-K9-NA identifies the SF300-48 managed switch, with 48 10/100 access ports and four Gigabit uplinks. SRW248G4-K9 is the hardware ordering identifier; -NA selects its regional form. Two uplinks use dedicated copper connections, while two offer shared copper/SFP media choices rather than additional independent fiber ports.
The Cisco SF300-48 supports browser-based HTTP/HTTPS management, CLI access through the console or SSH/Telnet, and SNMP monitoring. Administrators can use the web interface for configuration and maintenance, command-line access for direct administration, and SNMP versions 1, 2c, or 3 for integration with network monitoring systems.
SRW248G4-K9-NA is discontinued: end of sale was August 2, 2018, and Cisco service ended August 31, 2023. Software maintenance ended August 2, 2019. Orders for retained installations therefore require an independent maintenance plan rather than an assumption that Cisco support can be renewed.
ORM Systems offers SRW248G4-K9-NA 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 every condition, terms apply. Cisco's limited lifetime hardware warranty ended with service on August 31, 2023.
No, SRW248G4-K9-NA does not supply PoE on any access or uplink port. Connected phones, cameras, and access points need their own power source. The internal AC supply powers the switching hardware rather than delivering endpoint power through Ethernet cables, so endpoint power must be specified separately.
SRW248G4-K9-NA accepts MGBSX1 for multimode Gigabit fiber and MGBLX1 for single-mode Gigabit fiber in its two combo SFP interfaces. Each SFP interface shares operation with its corresponding copper connection. Select the transceiver against the existing fiber type and the optical interface at the opposite end.
Yes, the Cisco SF300-48 supports static IPv4 routing between local subnets. Routing configuration requires the appropriate IP interfaces and static routes; management connectivity alone does not establish inter-subnet forwarding. The routing feature is a static configuration capability rather than a dynamic routing control plane.
The Cisco SF300-48 is a full-width rack switch measuring 440 mm wide, 44.45 mm high, and 257 mm deep. Its 3.39 kg chassis fits a 1U rack position. Confirm available rack depth, cable clearance, and the mounting hardware included with the selected condition before ordering.
No, SRW248G4-K9-NA uses a fixed internal AC supply rather than dual redundant PSU modules. The input accepts 100–240V AC, and maximum system consumption is 29.2W. A deployment requiring independent power paths must address that requirement outside the chassis rather than adding a second internal supply.
SRW248G4P-K9-NA supplies PoE with a shared 375W budget, while SRW248G4-K9-NA provides no PoE output. Both are discontinued 48-port Fast Ethernet models with Gigabit uplinks. The non-PoE version matches separately powered endpoints; the PoE version matches existing installations that depend on switch-supplied endpoint power.
SRW248G4-K9-NA has 48 Fast Ethernet access ports, while SRW224G4-K9 has 24; both configurations include four Gigabit uplink connections. Both belong to the retired Small Business 300 family. The larger configuration matches a higher existing connection count, while the smaller configuration matches a 24-port replacement requirement.
C1300-48T-4G provides 48 Gigabit access ports, whereas SRW248G4-K9-NA provides 48 Fast Ethernet access ports. C1300-48T-4G is the current migration endpoint after the discontinued intermediate replacements. The older switch matches retained 100 Mbps installations; the current model suits replacement projects requiring Gigabit connections throughout the access layer.
