SRW248G4-K9-UK is a fanless, managed Layer 2+ switch with 48 non-PoE 10/100 access ports and four fixed Gigabit uplinks in a 1U rack chassis. Two uplinks are dedicated copper connections; the remaining two provide shared copper/SFP connections, allowing the uplink medium to match existing cabling. The Cisco SF300-48 belongs to the Small Business 300 family and connects desktop computers, printers, and other separately powered Ethernet equipment. Its access ports remain Fast Ethernet even when the uplinks operate at Gigabit speed. The discontinued SRW248G4P-K9-UK adds PoE for powered endpoints. This non-PoE configuration serves an existing Fast Ethernet installation where endpoint power comes from another source and the purchase requirement is managed connectivity rather than Gigabit speed at every desk.

17.6 Gbps switching capacity accommodates the fixed access and uplink connections, while 13.1 Mpps forwarding performance describes operation with 64-byte packets. Static IPv4 routing supports communication between VLANs; this is separate from the physical speed of the access interfaces. An 8000-entry MAC address table supports address learning across the connected network. SRW248G4-K9-UK combines 128 MB of memory with 16 MB of flash for switch operation and software storage. Browser-based administration provides a graphical configuration path, while a serial console and remote CLI access support command-driven administration. HTTPS protects browser sessions, and SSH provides encrypted remote access. STP, RSTP, and MSTP provide spanning-tree options for redundant Ethernet connections. Access control lists provide traffic filtering. A 24.8W maximum published draw at 220V provides a power-planning reference, and the 0°C to 40°C operating range sets the installation temperature boundary.
ORM Systems supplies SRW248G4-K9-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested for rated-speed port links, optics bay recognition, and clean boot, with firmware verified and configuration wiped to factory default. Specify the condition, matching optics, and quantities on the PO. New units carry up to a 3-year extended warranty and certified refurbished units up to 1 year, with 30-day returns on every condition, terms apply; Cisco's original limited lifetime coverage ended August 31, 2023. POs are accepted for single-unit and volume orders, with Net-30 for government, regional stock and RMA across the UK, EU, US, and MEA, and RMA with advance replacement.

When preparing replacement configurations before installation, aggregation settings need validation against the neighboring equipment rather than simply copying individual port assignments. LACP supports eight aggregation groups. Record the intended member ports, remote configuration, and required cabling, then include the staging configuration requirements with the hardware order.
When a branch installation carries voice alongside ordinary desktop traffic, queue assignments and traffic classification need to be established before cutover. Four hardware queues provide the scheduling structure. Identify the required voice VLAN and classification settings, then specify configuration staging and the endpoint power arrangements before issuing the PO.
Gigabit connectivity at every access port
SRW248G4-K9-UK limits its 48 access ports to 100 Mbps. C1300-48T-4G provides 48 Gigabit access ports and is the current endpoint of the replacement chain.
Power delivery to connected endpoints
SRW248G4-K9-UK provides non-PoE access connections and cannot supply Ethernet power to phones, cameras, or access points. Connected equipment requires a separate source of power.

SRW248G4-K9-UK identifies the Cisco SF300-48 managed switch, with 48 10/100 access ports and four Gigabit uplink connections, including two shared copper/SFP combinations. The SF300-48 model name and complete ordering PID identify the same configuration; this is not a switch with 48 Gigabit access ports.
SRW248G4-K9-UK supports browser-based management and CLI access through a serial console, SSH, or Telnet. HTTPS encrypts browser sessions, while SSH protects remote command access. Specify the administration connection during staging and retain console access for initial configuration or recovery work.
SRW248G4-K9-UK is discontinued: Cisco end of sale was August 2, 2018, and Cisco support ended August 31, 2023. Software maintenance ended August 2, 2019. Purchasing new sealed stock or refurbished hardware does not restart those manufacturer service milestones or create a new Cisco support period.
ORM Systems offers SRW248G4-K9-UK new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Every condition has 30-day returns, terms apply. Cisco's original limited lifetime coverage ended with Cisco support on August 31, 2023.
SRW248G4-K9-UK provides four Gigabit uplink connections: two dedicated copper ports and two combo connections with copper and SFP interfaces. Each combo connection permits one medium to operate at a time. Installing an SFP therefore changes the connection medium rather than adding another independently usable uplink.
Yes, SRW248G4-K9-UK supports static IPv4 routing between VLANs. Routed interfaces and static routes must be configured for the intended subnets, rather than assuming VLAN creation alone establishes the required forwarding. Include the subnet addressing and routing requirements in the configuration scope when ordering a staged unit.
SRW248G4-K9-UK is fanless and has published worst-case consumption of 24W at 110V and 24.8W at 220V. Its internal power supply accepts 100-240V AC. Use the applicable consumption figure when allocating electrical capacity; endpoint power is separate because this configuration does not provide PoE.
SRW248G4-K9-UK provides no endpoint power, whereas the discontinued SRW248G4P-K9-UK provides PoE with a 375W shared budget. The non-PoE model suits separately powered endpoints; the PoE model was the powered alternative. Both are discontinued, so choosing between them does not restore an active Cisco product lifecycle.
SRW248G4-K9-UK provides 48 Fast Ethernet access ports, while SRW224G4-K9-UK provides 24. Both configurations include two dedicated Gigabit copper uplinks and two Gigabit combo connections. The larger unit suits a higher endpoint count; the smaller unit suits fewer connections. Both models are discontinued.
C1300-48T-4G provides 48 Gigabit access ports, while SRW248G4-K9-UK provides 48 Fast Ethernet access ports. The Catalyst 1300 model is the current endpoint of the migration chain through the discontinued SF350 and CBS350 models. The older switch serves legacy matching; the newer model serves Gigabit access requirements.
SRW248G4-K9-UK replaced SRW248G4-UK, the earlier WebView switch with 48 10/100 ports and four Gigabit connections, including two combo SFP positions. The newer unit is the SF300-48 managed model. Treat the older and newer complete PIDs as different products when matching an installed spare.
SRW248G4-K9-UK uses a 1U rack enclosure measuring 440 mm wide, 44.45 mm high, and 257 mm deep, with a weight of 3.39 kg. Allow additional installation space for connected cables and access to the interfaces, and confirm the mounting hardware required for the intended cabinet.
