SG300-20-K9-EU is a Cisco Small Business 300 managed access switch with 18 fixed 10/100/1000 copper ports, plus two copper/SFP combo 1G uplinks. The full-width 1U enclosure fits a small business access rack with an internal AC supply. Each combo position accepts a copper or fiber connection, with only one side active at a time. Static inter-VLAN routing gives the platform a Layer 2+ role without an enterprise license tier. The SG300-20 configuration serves existing Gigabit wiring while allowing a Gigabit distribution handoff. Endpoint power must come from another device or supply. The fixed uplink layout requires no network module purchase.

40 Gbps switching capacity is the model's published fabric figure, and 29.76 Mpps forwarding measures its small-packet rate. SG300-20-K9-EU has 128 MB of CPU memory, 16 MB of flash, and an aggregate packet buffer shared across active ports. The web interface, SSH or Telnet CLI, SNMP, VLAN configuration, STP/RSTP/MSTP, and LACP support day-to-day managed operation. Static IPv4 routing can connect configured VLANs; dynamic enterprise routing protocols are outside this platform role. Both copper/SFP combo uplinks accept documented MGBSX1 or MGBLX1 1G optics, with each optical interface sharing a logical position with its paired copper port. Fanless cooling removes a mechanical fan from the chassis. An internal universal AC supply powers the unit. Hardware stacking and a redundant internal supply bay are absent. Confirm that the Rack-Mount 1U installation has enough clearance for the chassis and that the local power connection matches Internal AC PSU. Keep the existing port map, VLAN plan, management settings, and configuration backup available while staging this exact replacement hardware for a production site.
ORM Systems offers SG300-20-K9-EU new sealed or certified refurbished and accepts purchase orders for either condition. Certified refurbished managed units are inspected and bench-tested, firmware verified, and wiped to factory default; every port is checked for a link at rated speed. SFP bay recognition is checked for the two combo positions. Confirm the Cisco ordering PID SRW2016-K9-EU, regional power connection, and any required MGBSX1 or MGBLX1 optics before releasing the PO. New stock has up to a 3-year extended ORM warranty, refurbished stock up to 1 year, and every condition has 30-day returns subject to terms. Volume orders may use PO acceptance, Net-30 for government, UK/EU/US/MEA stock, and RMA with advance replacement.

A site maintains 18 Gigabit endpoint links and needs a compatible managed switch for an existing Small Business 300 configuration. SG300-20-K9-EU provides two copper/SFP combo uplinks without a removable network module. Record the port plan, saved VLAN configuration, regional power connection, and chassis label before the purchase order.
A distribution handoff changes to fiber while the existing 18 copper access connections stay in service. SG300-20-K9-EU offers two 1G copper/SFP combo positions; each SFP excludes its paired RJ-45 connection. Specify MGBSX1 for multimode or MGBLX1 for single-mode fiber and record the cable type before the PO.
A multi-site small business keeps a spare for SG300-20 deployments after the 300 Series retirement. SG300-20-K9-EU uses the Cisco order number SRW2016-K9-EU for EU region. Confirm the chassis label, boot state, matching configuration, mounting hardware, and required power connection before the purchase order is released.
Ten gigabit distribution uplinks
SG300-20 has 1G copper/SFP uplinks and no built-in 10G port. Choose a currently supported switch with documented 10G uplinks when the distribution requirement is 10G.
Hardware stack as one chassis
SG300-20 has no dedicated hardware stacking capability. Specify a currently supported stackable switch where a single control plane across multiple chassis is required.
Active Cisco service coverage
Cisco places the Small Business 300 family among retired switches. Select a currently supported Cisco platform when vendor maintenance or security updates are mandatory.
Power delivered to access devices
The 18 copper access ports provide no PoE output. Select a current PoE model when connected endpoints require switch-supplied power.

SG300-20-K9-EU identifies the Cisco SG300-20 managed Gigabit switch with 18 copper access ports. Cisco's regional ordering PID is SRW2016-K9-EU; the catalog model spelling and ordering PID should be matched before purchase. The EU regional form concerns the sales and power connection, not a different Ethernet port layout.
SG300-20-K9-EU uses the Small Business 300 web user interface and command-line access over SSH or Telnet. SNMP monitoring, VLAN settings, and saved configurations are available on the managed platform. Keep a backup of the installed configuration and verify the software image before introducing a replacement unit.
SG300-20-K9-EU belongs to Cisco's retired Small Business 300 switch family. Cisco no longer supports products in that retired category. An installed unit can remain a replacement target, but purchasing should account for firmware availability, a tested spare, and an independent RMA path rather than assuming new Cisco service.
SG300-20-K9-EU is available from ORM Systems new sealed or certified refurbished. ORM Systems offers new sealed stock with up to a 3-year extended warranty or certified refurbished stock with up to 1 year; both carry 30-day returns subject to terms. Cisco lists the 300 Series as retired, so Cisco service and the original limited lifetime hardware coverage have ended.
SG300-20-K9-EU does not provide PoE on its 18 access ports. Phones, cameras, or wireless access points attached to it need a separate power source. The two copper/SFP combo uplinks and any dedicated Gigabit uplinks carry network traffic only; they do not add powered endpoint ports.
SG300-20-K9-EU has two 1G RJ-45/SFP combo positions. Each logical uplink can operate over copper or an installed SFP optic, with the unused medium inactive. MGBSX1 is a supported multimode option and MGBLX1 is a supported single-mode option; select fiber type and optics before ordering.
SG300-20-K9-EU supports static routing between VLANs as a Layer 2+ Small Business 300 switch. It does not require a Catalyst Network Essentials or Network Advantage license tier. Define the gateway interfaces and upstream route plan when moving a configuration from another switch, rather than treating management access as routing.
SG300-20-K9-EU cannot join a true hardware stack because the 300 Series model has no dedicated stack facility. Its uplink ports are ordinary Ethernet interfaces, and managing multiple units does not create one stack control plane. Record a separate configuration, power feed, and spare-unit plan for each chassis.
SG300-20-K9-EU supplies 18 fixed Gigabit access ports and 2 logical 1G uplink positions. Access ports reach 1G; the built-in uplinks also operate at 1G. No 10G uplink is built in. Match endpoints and distribution links to those published speed classes before purchase.
SG300-20-K9-EU uses an internal AC supply with a 100–240V AC input. The published 16.26W worst-case draw applies to the unpowered switch. There is no second internal hot-swappable PSU bay. Verify the included regional connection and available electrical capacity at the installation location.
