SG350X-8PMD-K9-UK provides multigigabit powered access for small business networks, combining eight 100M/1G/2.5G copper access ports with two fixed 10G combo uplinks in a desktop chassis. This managed, Layer 2+ switch belongs to the Cisco 350X Series and connects wireless access points, IP phones, and surveillance cameras. PoE+ operates across the access ports, with four selected ports also supporting 60W delivery for compatible higher-draw devices. The discontinued SG350X-24P-K9-UK instead distributes 195W of PoE across 24 Gigabit access ports. Each combo uplink provides a choice between 10GBASE-T copper and SFP+ fiber connectivity, with only one medium active per logical port. The uplinks are built in rather than added through an expansion card.

80 Gbps switching capacity handles traffic across the local switching fabric, while 29.76 Mpps forwarding supports 64-byte packets. 240W of shared PoE capacity requires endpoint power allocation rather than independent maximum-power reservations on every port. Static IPv4 and IPv6 routing enables inter-subnet forwarding without dynamic routing protocols; the IPv4 limit is 990 routes, while IPv6 supports 245 static routes and 106 interfaces. SG350X-8PMD-K9-UK combines 512 MB of memory with 256 MB of flash for control software and image storage. The SG350X-8PMD shares a 1.5 MB packet buffer across all ports rather than assigning a fixed buffer to each endpoint. STP/RSTP/MSTP controls Layer 2 loops, and LACP supports configured link aggregation groups. Management options include an HTTP/HTTPS web interface, CLI access over SSH or Telnet, SNMP, Smart Network Application, and FindIT Network Manager with an embedded probe. A separate RJ-45 console connection provides local administrative access when network management connectivity is unavailable.
Specify SG350X-8PMD-K9-UK in new sealed or certified refurbished condition, and put the quantity, regional power lead, and required SFP-10G-SR= or SFP-10G-LR= optics on the PO. Refurbished units are inspected and bench-tested, including PoE output under load on every powered port, with firmware verified and configuration wiped to factory default. ORM coverage is up to a 3-year extended warranty for new units and up to 1 year for refurbished units, plus 30-day returns on every condition, terms apply; Cisco's separate limited lifetime hardware warranty ends July 31, 2027. Enterprise and volume orders support POs, Net-30 for government, and RMA with advance replacement through UK, EU, US, and MEA regional stock/RMA.

When an existing 350X stack needs another member, the switch can join a hybrid stack with SG350X, SG350XG, or SX350X units. Ring and chain layouts use network interfaces rather than a separate stacking module. Specify SFP-H10GB-CU1M= for a 1 m copper interconnect and reserve the required links before the PO.
When standardizing SG350X-8PMD-K9-UK replacements across regional sites, the UK ordering variant covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia. Country selection is a procurement detail rather than a different access-port configuration. Confirm each shipment's destination and required mains lead, then identify the regional variant explicitly on the purchase order.
When staging SG350X-8PMD-K9-UK units before deployment, dual software images allow an alternate image to remain available while firmware is prepared. The front USB Type A slot supports file and image handling without using an uplink. Specify the intended firmware image and configuration handoff before releasing the staging purchase order.
60W power on every access port
Only four access ports support 60W; the other four support 30W, and all powered ports share 240W. Simultaneous 60W delivery across every access port exceeds these limits.
Silent fanless operation
Active cooling uses one fan, with 41.3 dB acoustic noise at 25°C. This switch cannot satisfy a fanless requirement for an occupied desk or noise-restricted installation.
Cisco support beyond July 2027
Cisco service ends July 31, 2027. The discontinued migration model, CBS350-8MP-2X-UK, has no current successor in its migration chain and is not a current replacement option.

SG350X-8PMD-K9-UK identifies the 350X stackable managed switch with eight multigigabit PoE+ access ports. The 8PMD configuration supplies 100M/1G/2.5G access, including four 60W-capable ports, plus two 10G combo uplinks. K9 is retained in the complete order identifier, while UK selects the regional ordering variant covering the United Kingdom and associated markets.
SG350X-8PMD-K9-UK is managed through an HTTP/HTTPS web UI, an RJ-45 console, CLI over SSH or Telnet, SNMP, Smart Network Application, and FindIT Network Manager with an embedded probe. The web UI includes a customizable dashboard and simple or advanced configuration modes; FindIT Network Discovery Utility also provides browser-based device discovery.
SG350X-8PMD-K9-UK provides a shared 240W PoE budget across eight powered access ports, with four ports supporting 60W and the remaining four supporting 30W. The per-port ceilings do not represent simultaneous available output. Endpoint allocations must remain within the common budget, particularly when higher-draw devices occupy the 60W-capable connections.
SG350X-8PMD-K9-UK has two 10G combo uplinks, each sharing a 10GBASE-T connector with an SFP+ cage; only one side of each pair can be active. SFP-10G-SR= supports multimode fiber, and SFP-10G-LR= supports single-mode fiber. These fixed uplinks accept transceivers rather than removable uplink cards, so specify the chosen optics rather than a network module.
Cisco 350X Series switches support true horizontal stacking with four members, including mixed SG350X, SG350XG, and SX350X models. Interconnects use 10G copper or fiber interfaces. Compatible copper options include SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M=; select the cable length and ring or chain layout while reserving interfaces for the stack connections.
The SG350X-8PMD supports static IPv4 and IPv6 routing, with 990 IPv4 static routes and 128 IPv4 interfaces, plus 245 IPv6 static routes and 106 IPv6 interfaces. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopbacks. Dynamic routing is not included, so route changes require static configuration.
The SG350X-8PMD uses a desktop chassis measuring 344.4 mm wide, 44 mm high, and 252.5 mm deep, with a weight of 2.74 kg. A mounting kit is included with the original package despite the narrower chassis width. Confirm the mounting hardware supplied on the quoted order before planning installation.
SG350X-8PMD-K9-UK accepts 100-240V AC through an internal universal supply, with worst-case total draw of 312.4W at 110V or 307.3W at 220V when PoE is included. These figures include endpoint power; the 240W PoE allowance is not total AC demand. Use the full input draw when allocating UPS or circuit capacity.
SG350X-8PMD-K9-UK is discontinued, with end of sale on July 30, 2022 and final Cisco support on July 31, 2027. Software maintenance ended July 30, 2023. Its designated migration model, CBS350-8MP-2X-UK, is also discontinued and has no current onward migration product, so that model is not a current successor.
ORM Systems offers SG350X-8PMD-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. Returns are available for 30 days in either condition; terms apply. Cisco's separate limited lifetime hardware warranty is bounded by the last date of support, July 31, 2027.
SG350X-8PMD-K9-UK shares 240W of PoE power, while SG350X-24P-K9-UK shares 195W across 24 Gigabit access ports. Both are discontinued 350X models, making this a legacy replacement comparison. The eight-port model suits multigigabit endpoints; the 24-port model serves larger Gigabit endpoint counts with a lower shared power allocation.
SG350X-8PMD-K9-UK has two 10G combo uplinks, whereas SG350X-12PMV-K9-UK has four 10G uplinks comprising two combo connections and two dedicated SFP+ connections. Both models are discontinued. For legacy requirements, the eight-port model provides the smaller uplink allocation, while the 12-port model accommodates more separate upstream or stacking connections.
SG350X-8PMD-K9-UK provides eight 2.5G access ports, whereas SG350X-24PD-K9-UK provides 24 access ports comprising four 2.5G and 20 Gigabit connections. Both are discontinued. The eight-port model suits legacy installations needing multigigabit speed on every access connection; the 24-port model suits higher endpoint density with only four multigigabit connections required.
