SRW2048-K9-UK is a managed Layer 2+ Gigabit Ethernet switch with 48 copper access ports and four fixed Gigabit uplinks: two dedicated RJ-45 connections and two copper/SFP combo connections. This non-PoE configuration connects separately powered computers, printers, and other wired devices. Cisco Small Business 300 switching combines VLAN-based access with a 1U rack-mount chassis for small-business networks. Each combo connection activates either its copper interface or its SFP interface, so the two interfaces cannot operate independently. The SG300-52P-K9 adds 48 PoE+ ports and a shared 375W power budget, but that model is also discontinued. The SG300-52 designation identifies this configuration within the family, keeping replacement orders distinct from the earlier WebView hardware.

104 Gbps switching capacity supports the fixed port configuration, while 77.38 Mpps forwarding performance applies to 64-byte packets. 512 static IPv4 routes and 128 IP interfaces provide the limits for locally configured routed networks. Physical ports, link aggregation groups, VLAN interfaces, and loopbacks can carry routing interfaces. SRW2048-K9-UK uses 128 MB DRAM and 16 MB flash for its embedded software and saved configuration. STP/RSTP/MSTP provide spanning-tree operation, while LACP supports aggregated connections. Four hardware queues support traffic prioritization through strict-priority or weighted round-robin scheduling. The address table accommodates 16384 MAC entries, and jumbo frames reach 9216 bytes. IPv6 operates in host mode rather than providing equivalent routed forwarding. Two fans move air through the enclosure, which requires an operating environment between 0°C and 40°C. Maximum system consumption of 45.9W gives a ceiling for allocating electrical capacity without an endpoint-power allowance.
ORM Systems offers SRW2048-K9-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, and optics bay recognition, with firmware verified and configuration wiped to factory default. ORM warranty is up to a 3-year extended term for new units and up to 1 year for certified refurbished units; both conditions have 30-day returns, terms apply, while Cisco's former limited lifetime hardware warranty ended October 31, 2023. Specify condition and quantity, and confirm included power cord and mounting hardware before submitting the PO. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock/RMA coverage across UK, EU, US, and MEA.

When an installed SRW2048-UK needs replacement, matching the older WebView name is insufficient: the SG300-52 generation uses refreshed hardware and software. Treat the change as a switch migration, not a firmware conversion of the old chassis, and specify the complete regional ordering number before the PO.
When several sites need the same configuration baseline, text-editable configuration files and Secure Copy autoconfiguration let the Small Business 300 family reuse prepared settings. DHCP options also support configuration-file download. Prepare each site's addressing and file-transfer requirements before ordering quantities for a standardized rollout.
When a lab or staging bench needs traffic capture before equipment enters service, one mirroring session can send traffic from eight source ports to one destination port. Reserve the analyzer connection and decide which interfaces need capture before specifying the test setup and switch quantity.
10G uplinks to distribution
SRW2048-K9-UK limits its fixed uplinks to 1G. C1300-48T-4X retains 48 Gigabit access ports and provides four 10G SFP+ uplinks for a current-model refresh.
PoE-powered phones or access points
SRW2048-K9-UK supplies no Ethernet power. C1300-48P-4G offers 48 Gigabit PoE access ports with four 1G SFP uplinks when powered endpoints are a purchase requirement.

SRW2048-K9-UK is the UK regional ordering form of the Cisco SG300-52 managed Gigabit switch. SRW2048-K9 identifies the hardware model, while UK identifies the regional power and regulatory variant. The configuration provides 48 access connections plus four Gigabit uplinks; the K9 form is distinct from the older SRW2048-UK.
SRW2048-K9-UK is managed through HTTP/HTTPS web configuration, a full or menu-based CLI over console, SSH or Telnet, and SNMP v1/v2c/v3. The Small Business 300 software also includes Cisco Small Business FindIT Network discovery and Cisco OnPlus integration. SSH and HTTPS provide encrypted remote-management sessions.
SRW2048-K9-UK is discontinued: sales ended October 4, 2018, and Cisco support ended October 31, 2023. Its original replacement SG350-52-K9-UK and subsequent CBS350-48T-4G-UK are also discontinued. C1300-48T-4G is the current migration destination, rather than either intermediate model, for a refresh beyond the completed Cisco support period.
ORM Systems supplies SRW2048-K9-UK new sealed or certified refurbished. ORM warranty is up to a 3-year extended term for new units and up to 1 year for certified refurbished units; 30-day returns cover both conditions, terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on October 31, 2023.
SRW2048-K9-UK replaces SRW2048-UK, the earlier 48-port Gigabit WebView switch. SG300-52 is a hardware and software refresh rather than a firmware-only upgrade of that predecessor. For replacement planning, identify the installed label and prepare the new configuration against the SG300-52 management environment rather than assuming the two generations are interchangeable.
SRW2048-K9-UK has 48 Gigabit access ports, two dedicated Gigabit copper uplinks, and two Gigabit copper/SFP combo uplinks. Each combo pair shares one active connection: using its fiber interface does not add another independent uplink. Choose copper or fiber for each shared pair when preparing the connection schedule.
Yes, SRW2048-K9-UK supports static IPv4 routing with 512 routes and 128 IP interfaces, giving the configuration Layer 2+ capability. Interfaces can be assigned to physical ports, link aggregation groups, VLANs, or loopbacks. Use those limits when sizing inter-VLAN routing, and keep IPv6 host mode distinct from IPv4 routed forwarding.
MGBLX1 and MGBLH1 are supported 1G single-mode SFP choices for the Small Business 300 series, with maximum reaches of 10 km and 40 km respectively. Select MGBLX1 or MGBLH1 for the actual fiber path and matching far end; either occupies an existing fixed SFP cage rather than adding ports.
Yes, SRW2048-K9-UK fits a 1U rack position in a full-width chassis measuring 440 mm wide, 44.45 mm high, and 257 mm deep. Unit weight is 3.91 kg, and a mounting kit is part of the original package. Reserve clearance for cabling and airflow when confirming the cabinet layout.
SG300-52P-K9 adds 48 PoE+ access ports with a shared 375W budget, whereas SRW2048-K9-UK supplies no PoE. Both models are discontinued. The non-PoE configuration matches separately powered endpoints; the PoE+ version corresponds to legacy installations needing switch-provided endpoint power rather than a current-generation procurement standard.
SRW2048-K9-UK provides 48 Gigabit access ports, while SRW2024-K9 provides 24; both have four Gigabit uplinks. Both models are discontinued. The higher-density configuration fits legacy replacement plans with more copper endpoints, while the smaller configuration matches existing 24-port installations where maintaining that density is the procurement requirement.
C1300-48T-4G provides four dedicated 1G SFP uplinks, whereas SRW2048-K9-UK provides two copper uplinks and two copper/SFP combo uplinks. C1300-48T-4G is the current migration destination after the discontinued intermediate models. SRW2048-K9-UK matches exact legacy replacement requirements; C1300-48T-4G suits a refresh requiring four independent fiber uplinks.
No, SRW2048-K9-UK uses a single internal AC supply rather than redundant power modules. The universal input accepts 100-240V AC at 47-63 Hz, and maximum system consumption is 45.9W. Two fans provide cooling, so the enclosure is not fanless; account for its airflow requirements when planning the installation.
