SG355-10P-K9-UK is a fanless Layer 2+ managed switch with eight Gigabit Ethernet PoE+ access ports and two fixed Gigabit copper/SFP combo uplinks in a full-width 1U chassis. The Cisco 350 Series serves small-business networks connecting computers, IP phones, wireless access points and other Ethernet endpoints. Each combo uplink allows copper or fiber connectivity, with only one connection active per pair. The discontinued SG350-10P-K9-UK uses an external power adapter, whereas this model houses its AC supply internally. Voice VLAN assigns telephone traffic to a voice-specific VLAN, while configurable traffic priorities distinguish communications from ordinary data transfers. Browser configuration and command-line access support installations where administrators need direct control over port settings, network segmentation and endpoint access rather than an unmanaged Ethernet connection.

62W of shared PoE output requires endpoint allocations to stay within the aggregate allowance. 990 static IPv4 routes support routing between local subnets, while PBR directs selected traffic toward different next hops using access-control criteria. 83.5W maximum power consumption at 110V AC provides a reference for circuit loading when the switch supplies powered endpoints. SG355-10P-K9-UK combines 512 MB of memory with 256 MB of flash for its managed configuration and software. A shared 1.5 MB packet buffer serves traffic across the ports, and the MAC table holds 16000 addresses. STP/RSTP/MSTP provide spanning-tree options, while LACP supports negotiated link aggregation. Administrators can use HTTP/HTTPS browser access or the scriptable Textview CLI for configuration. Within the Cisco Small Business portfolio, this configuration provides static routed access rather than a hardware stack. DHCP snooping and Dynamic ARP Inspection add controls against unauthorized address assignment and inconsistent address bindings.
ORM Systems offers SG355-10P-K9-UK new sealed and certified refurbished; refurbished managed units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. Specify quantity, condition and delivery region before issuing the PO; ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns on every condition, terms apply. Cisco's separate limited lifetime hardware warranty and service end October 31, 2026. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA coverage across the UK, EU, US and MEA.

An office refresh that separates employee, voice and guest networks may require local routing rather than sending every inter-subnet connection upstream. The switch supports 128 IP interfaces, including interfaces on physical ports, VLANs and link aggregation groups. Confirm the required interface inventory and routing design before specifying the purchase quantity.
A rollout across several offices may require a common provisioning method before individual locations receive hardware. Cisco Network Plug and Play supports coordinated device provisioning, including Cisco PnP Connect. Establish the configuration ownership, provisioning workflow and destination-specific settings before the purchase order fixes quantities and regional delivery requirements.
A staging bench preparing switches before shipment needs a repeatable way to transfer configurations and software. The front USB Type-A connection supports file and image management, and dual software images support firmware upgrade preparation. Specify the staging configuration and acceptance checks before releasing the hardware purchase order.
10G uplinks to distribution
SG355-10P-K9-UK has 1G combo uplinks. C1300-8MGP-2X provides two 10G SFP+ uplinks but changes the access configuration to four 2.5G ports and four 1G ports.
30W simultaneously on every powered port
SG355-10P-K9-UK shares 62W across its powered ports, so all eight cannot draw 30W simultaneously. Specify a higher aggregate PoE budget for that endpoint requirement.

SG355-10P-K9-UK identifies the SG355-10P Gigabit PoE+ model with the UK regional suffix. The configuration comprises eight powered access ports and two Gigabit copper/SFP combo uplinks. UK covers the United Kingdom and several other markets; K9 remains part of the complete order identifier.
The Cisco 350 Series supports an HTTP/HTTPS web interface, console access and Textview CLI over SSH or Telnet. Additional paths include SNMP versions 1, 2c and 3, Smart Network Application, FindIT Network Manager and Probe, FindIT Network Discovery, Cisco Active Advisor and Network Plug and Play provisioning.
SG355-10P-K9-UK reached end of sale on October 30, 2021, and Cisco support ends October 31, 2026. Software maintenance ended October 30, 2022. The original migration model, CBS350-8P-2G-UK, is also discontinued; the forward migration chain now reaches C1300-8P-E-2G for buyers specifying replacement hardware.
SG355-10P-K9-UK is available new sealed or certified refurbished. ORM provides up to a 3-year extended warranty on new units and up to 1 year on refurbished units, plus 30-day returns in every condition; terms apply. Cisco's separate limited lifetime hardware warranty and service end October 31, 2026.
SG355-10P-K9-UK provides a 62W shared PoE budget with AC power, across eight PoE+ access ports. An individual powered port can supply 30W while aggregate allocations remain within that budget. Eight endpoints cannot all receive their per-port maximum simultaneously, so endpoint power requirements must be totaled before purchase.
The Cisco 350 Series supports MGBSX1 for multimode fiber connections to 500 m and MGBLX1 for single-mode fiber connections to 10 km. Each combo uplink uses either its copper connection or its SFP connection, not both simultaneously. Select the transceiver for the fiber type and required distance.
Yes, SG355-10P-K9-UK supports static IPv4 routing between network interfaces, with 990 static routes and 128 IP interfaces. PBR can direct selected traffic to different next hops using access-control criteria. This Layer 2+ configuration supports local subnet routing, so confirm route and interface requirements before assigning the switch that role.
Yes, SG355-10P-K9-UK can receive power through its copper uplinks from a compatible PoE source. Supported input options include PoE, PoE+ and 60W PoE. Working AC power takes priority; uplink power can act as backup, and downstream PoE availability changes with the selected input arrangement.
The Cisco SG355-10P uses a full-width Rack-Mount 1U chassis measuring 440 mm wide, 44 mm high and 203 mm deep. Its weight is 2.36 kg, and cooling is fanless. The internal AC supply keeps the power conversion hardware inside the chassis rather than in a separate adapter.
SG355-10P-K9-UK provides a 62W PoE budget, whereas SG350-10MP-K9-UK provides 124W. Both models are discontinued. For maintaining an existing installation, SG355-10P-K9-UK suits a lower aggregate endpoint load, while SG350-10MP-K9-UK accommodates a larger combined powered load within its own allowance; total endpoint demand before selecting either.
SG355-10P-K9-UK has an internal AC power supply, while SG350-10P-K9-UK uses an external AC adapter. Both models are discontinued. SG355-10P-K9-UK suits maintenance orders requiring power conversion inside the switch chassis; SG350-10P-K9-UK suits existing installations arranged around a separate adapter, whose inclusion should be confirmed with the hardware order.
SG355-10P-K9-UK is discontinued and reaches its Cisco support cutoff on October 31, 2026, while C1300-8P-E-2G is the current migration model at the end of its replacement chain. SG355-10P-K9-UK suits legacy maintenance requirements; C1300-8P-E-2G suits buyers moving beyond the discontinued SG355 and intermediate CBS350 generation.
