SRW2048-K9-EU is a managed, non-PoE Gigabit switch with 48 RJ-45 access ports, two additional copper Gigabit ports, and two copper/SFP combo uplinks. The fixed uplink design operates at 1G; each combo connection uses either its copper interface or its SFP slot, not both simultaneously. Layer 2+ static routing extends the Small Business 300 family beyond VLAN bridging for small-business networks. Cisco SG300-52 is the model identity behind this regional ordering number and uses a full-width 1U rack chassis. The discontinued SRW2024-K9 reduces connection density to 28 logical ports while retaining the non-PoE Gigabit configuration. Attached phones, access points, and cameras require their own power arrangements rather than drawing power from these Ethernet ports.

104 Gbps switching capacity accommodates simultaneous switching across the available interfaces without oversubscribing the switching fabric. 77.38 Mpps forwarding performance specifies packet handling with 64-byte packets, separately from aggregate bandwidth. 45.9W maximum power consumption provides the upper published figure for electrical planning; the corresponding figure at 220V is 45.3W. STP/RSTP/MSTP provide spanning-tree controls for redundant Ethernet paths. Port security limits learned addresses, while RADIUS/TACACS+ support centralized authentication. SRW2048-K9-EU supports browser-based administration over HTTP/HTTPS, with SSH available for protected management access and TextView CLI for command-based configuration. Text-editable configuration files can be downloaded to another switch when preparing consistent settings. Jumbo frames accommodate frame sizes up to 10 KB. Energy Detect reduces port power when a copper link is down, and short-reach detection adjusts signaling for cables shorter than 10 m. These controls address interface operation rather than providing power to connected equipment.
ORM Systems supplies SRW2048-K9-EU new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify the required condition and accessories on the PO; returns cover 30 days on every condition, terms apply, while Cisco's original limited lifetime hardware warranty ended October 31, 2023. For enterprise and volume orders, POs are accepted, with Net-30 for government and RMA with advance replacement.

When a branch moves inter-VLAN forwarding onto local switching, Layer 3 system mode changes which traffic controls remain available. VLAN rate limiting and QoS policers are not operational in that mode. Check existing traffic policies and confirm the intended operating mode before specifying the configuration on the PO.
When several parallel connections must terminate on one managed device, link aggregation supports 8 groups with 8 active ports per group and 16 candidate ports for dynamic selection. Inventory the peer-side aggregation configuration and physical connections, then specify the required link count before ordering the switching hardware.
Switch-powered phones or access points
SRW2048-K9-EU supplies Ethernet data but no PoE output. Endpoints that depend on power through their network cable require a separate power arrangement; connecting them does not enable switch-delivered power.
10G connections to distribution
SRW2048-K9-EU limits its copper and combo uplinks to 1G. The SFP connections do not provide 10G operation, and the fixed uplink architecture has no removable uplink card.
Active Cisco service coverage
Cisco service for SRW2048-K9-EU ended October 31, 2023. C1300-48T-4G is the current migration destination, retaining 48 Gigabit copper ports while providing four dedicated Gigabit SFP uplinks.

SRW2048-K9-EU identifies the regional EU ordering form of the Cisco SG300-52 managed Gigabit switch. SRW2048-K9 is the hardware ordering name, while EU distinguishes the regional form. The configuration has 50 copper connections plus two copper/SFP combo connections; SRW2048-EU without K9 identifies an older, different switch.
SRW2048-K9-EU supports browser-based configuration, TextView CLI, and console-based access, with HTTP/HTTPS and SSH available for management connections. Telnet functionality is also available. Configuration files can be edited as text and transferred between switches, so administrative access and configuration handling should be included in the staging plan.
Yes, SRW2048-K9-EU reached end of sale on October 4, 2018, and its last date of Cisco support was October 31, 2023. Cisco service has ended. Software maintenance ended October 4, 2019, so an order for this model should not assume continuing manufacturer software maintenance or support.
ORM Systems offers SRW2048-K9-EU new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year. Returns cover 30 days on every condition, terms apply. Cisco's original limited lifetime hardware warranty and service ended October 31, 2023; certified refurbished units are inspected and bench-tested.
SRW2048-K9-EU replaces the discontinued SRW2048-EU 48-port Gigabit WebView switch. The replacement uses the SG300-52 model identity and is not simply another regional spelling of the older part number. When matching an installed unit, distinguish the complete K9 ordering number from the earlier SRW2048-EU hardware name.
Cisco SG300-52 provides two additional Gigabit copper connections and two Gigabit copper/SFP combo connections alongside its access ports. Each combo connection activates either copper or fiber, not both simultaneously. MGBSX1 and MGBLX1 are compatible transceiver choices for multimode and single-mode fiber respectively; the uplinks do not support 10G.
Yes, SRW2048-K9-EU supports static IPv4 routing when configured in Layer 3 system mode. The switch can therefore forward between IP networks rather than operating solely as a VLAN-aware bridge. VLAN rate limiting and QoS policers are unavailable in that mode, so existing traffic-control requirements need checking before changing operation.
SRW2048-K9-EU uses an internal universal AC power supply accepting 100-240V AC. Maximum published consumption is 45.9W at 110V and 45.3W at 220V. These figures describe the switch's own electrical consumption, not an endpoint power budget; the model has no PoE output for connected devices.
SRW2048-K9-EU provides 52 logical Gigabit connections, whereas SRW2024-K9 provides 28, making connection density the principal difference. Both belong to the discontinued Small Business 300 family. SRW2048-K9-EU suits higher-density legacy replacements; SRW2024-K9 suits smaller legacy installations where the lower connection count matches the existing requirement.
C1300-48T-4G provides four dedicated Gigabit SFP uplinks, whereas SRW2048-K9-EU combines two copper uplinks with two copper/SFP combo uplinks. The migration chain ends at C1300-48T-4G after discontinued intermediate replacements. SRW2048-K9-EU suits matching an existing legacy installation; C1300-48T-4G suits purchasing the current migration model with dedicated fiber uplinks.
No, SRW2048-K9-EU does not provide PoE output on its Ethernet ports. The SG300-52 configuration carries network traffic without supplying endpoint power. Phones, wireless access points, and cameras therefore need their own power arrangements; the presence of Gigabit interfaces or SFP connections does not change that limitation.
Cisco SG300-52 provides 104 Gbps switching capacity and 77.38 Mpps forwarding performance for 64-byte packets. Switching capacity describes aggregate bandwidth, while the forwarding figure describes packet processing. Both figures apply to this model and should be considered separately when matching an existing switch or sizing its intended traffic load.
