Powered Access for Small Business Wireless Networks

SG350X-12PMV-K9-EU puts multigigabit PoE+ access into a managed Layer 2+ switch for small-business networks. Twelve RJ-45 access ports support 100M, 1G, 2.5G, and 5G connections, while four fixed 10G uplinks comprise two dedicated SFP+ interfaces and two 10GBASE-T/SFP+ combo interfaces. Each combo interface uses either copper or fiber, not both simultaneously. The full-width 1U chassis belongs to the Cisco 350X Series and serves wireless access points, IP phones, and other powered endpoints without a removable uplink card. The discontinued SG350X-8PMD-K9-EU provides two 10G uplinks rather than four. Copper and fiber uplink choices let the purchase specification match existing distribution connections, while native intermediate access speeds distinguish this configuration from ordinary Gigabit access hardware.

Technical Details

200 Gbps switching capacity supports nonblocking forwarding at native port rates, and 148.8 Mpps forwarding with 64-byte packets defines the small-packet throughput limit. 375W of shared PoE power requires endpoint allocations to remain within the switch-wide budget, even though selected ports support 60W. Static IPv4 and IPv6 routing provides inter-VLAN forwarding without dynamic route exchange; 990 IPv4 static routes and 128 IP interfaces set the IPv4 limits. SG350X-12PMV-K9-EU combines 512 MB of memory, 256 MB of flash, and a 3 MB packet buffer shared across ports. The forwarding resources accommodate 16000 MAC addresses and 4094 active VLANs. STP/RSTP/MSTP handles Layer 2 topology control, while LACP aggregates links and DHCP snooping restricts untrusted address-server traffic. Browser and CLI administration keep this Cisco Small Business managed switch configurable locally, with SNMP available for monitoring. Image signing and Secure Boot apply to this model.

Ordering

SG350X-12PMV-K9-EU is offered new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and PoE output under load on every powered port, with firmware verified and configurations wiped to factory default. Specify condition and accessories on the PO: ORM provides up to 3-year extended warranty for new units, up to 1 year for certified refurbished, and 30-day returns on every condition; terms apply. Cisco's limited lifetime hardware warranty is bounded by July 31, 2027. Enterprise and volume orders support PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US, and MEA.

Buying Notes

Buying NotesKey Specs

Support window and migration

SG350X-12PMV-K9-EU requires a bounded support plan: sales ended July 30, 2022, and support ends July 31, 2027. Replacement CBS350-12NP-4X-EU is also discontinued, with no current successor.

Optics ordered with fiber

SG350X-12PMV-K9-EU fiber connections require separately ordered optics; choose SFP-10G-SR= for multimode fiber or SFP-10G-LR= for single-mode fiber, then match the fiber patching to the intended link.

Shared power allocation limit

SG350X-12PMV-K9-EU cannot allocate every port's maximum simultaneously: 8 x 60W + 4 x 30W = 600W exceeds the shared 375W budget. Size endpoint allocations before ordering.

Stack links consume interfaces

SG350X-12PMV-K9-EU stacking needs reserved 10G interfaces; include SFP-H10GB-CU1M= or SFP-H10GB-CU3M= for short interconnects. Ring and chain layouts require a port plan that also preserves the intended uplinks.

Best For

Branch Rollout Staging

A branch rollout that must reuse a common configuration can stage the 350X through Cisco Network Plug and Play and SCP configuration download. Dual firmware images keep two image choices available during preparation. Specify the baseline configuration, provisioning method, and acceptance checks before the PO.

Voice Endpoint Expansion

An office adding IP phones can use automatic voice VLAN assignment and Auto Smartports to apply endpoint-specific settings. Eight hardware queues provide separate traffic scheduling resources, while LLDP-MED supports voice endpoint discovery. Confirm the phone discovery method, voice VLAN configuration, and required QoS policy before specifying the order.

Stack Extension Planning

An existing SG350X installation needing another member can mix SG350X, SG350XG, and SX350X hardware in one stack. Cross-stack link aggregation supports connections across members, with eight aggregation groups available. Identify retained members and the cross-member link plan, then confirm the replacement unit's configuration before the PO.

Not Suitable If

60W power on every access port

SG350X-12PMV-K9-EU offers 60W on eight access ports and 30W on the remaining four. The shared 375W budget also prevents simultaneous maximum allocation across all twelve ports.

Dynamic routing between branch subnets

SG350X-12PMV-K9-EU supports static IPv4 and IPv6 routes, not dynamic route exchange. Automatic route-learning requirements must remain on a separate routing device rather than this access switch.

Fanless operation in occupied rooms

SG350X-12PMV-K9-EU uses three fans and produces 52.2 dB at 45°C. A zero-fan requirement cannot be met by this chassis; the cooling system is not fanless.

Manufacturer support beyond July 2027

SG350X-12PMV-K9-EU support ends July 31, 2027. Its discontinued CBS350-12NP-4X-EU replacement has no current successor, so the migration chain offers no current purchase alternative for longer-term manufacturer support.

Questions & Answers

What does the SG350X-12PMV-K9-EU part number identify?

SG350X-12PMV-K9-EU identifies the EU regional version of a 12-port 5G PoE stackable managed switch. SG350X identifies the family; 12 is the access-port count; PMV corresponds to the powered 5G configuration, including eight 60W-capable ports; EU selects the regional ordering version rather than a software license tier.

How is SG350X-12PMV-K9-EU managed?

SG350X-12PMV-K9-EU is managed through HTTP/HTTPS web UI, full or menu CLI over console, SSH or Telnet, and SNMP versions 1, 2 and 3. Network tools include Smart Network Application, FindIT Network Manager with the embedded Probe, FindIT Network Discovery Utility, Active Advisor, and Cisco Network Plug and Play with PnP Connect.

What is the PoE budget of SG350X-12PMV-K9-EU?

375W is the shared PoE budget of SG350X-12PMV-K9-EU across twelve powered access ports. Eight ports support 60W, while the remaining four support 30W. Endpoint allocations must remain within the total budget; individual port ratings do not guarantee simultaneous maximum power delivery from every powered port.

Which optics work with the 350X Series multigigabit switch?

SFP-10G-SR= and SFP-10G-LR= are supported 10G optics for the 350X Series, including SG350X-12PMV-K9-EU. SFP-10G-SR= uses multimode fiber, while SFP-10G-LR= uses single-mode fiber. Select the optic to match the fiber medium and link distance, and include matching optics and patching with the switch order.

How many uplinks does SG350X-12PMV-K9-EU have?

Four 10G uplink interfaces are built into SG350X-12PMV-K9-EU: two dedicated SFP+ interfaces and two 10GBASE-T/SFP+ combo interfaces. Each combo interface activates either its copper connection or its SFP+ connection. Copper and fiber connections on the same combo interface cannot operate simultaneously as separate uplinks.

How many switches can the 350X Series stack together?

Four members form one hardware stack in the 350X Series, with true horizontal stacking and single-system management. Ring and chain arrangements use 10G copper or fiber interconnects. Supported short copper interconnects include SFP-H10GB-CU1M= and SFP-H10GB-CU3M=; reserve the required interfaces when planning uplink connections.

Can SG350X-12PMV-K9-EU route between VLANs?

Yes, SG350X-12PMV-K9-EU routes IPv4 and IPv6 traffic using static routes. IPv4 limits are 990 static routes and 128 IP interfaces; IPv6 limits are 245 static routes and 106 interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces rather than dynamic route exchange.

Is the 12-port 5G PoE stackable managed switch rack-mountable?

Yes, the 12-port 5G PoE stackable managed switch is a full-width 1U rack-mount model, with mounting hardware in the standard package. SG350X-12PMV-K9-EU measures 440 mm wide, 44 mm high, and 257 mm deep, and weighs 4.24 kg. Confirm rack space and mounting hardware when specifying the order.

What power supply does SG350X-12PMV-K9-EU use?

SG350X-12PMV-K9-EU uses an internal universal 100-240V AC power supply rather than an external adapter. Worst-case consumption with PoE is 494.5W at 110V or 476.4W at 220V. The standard package includes a power cord; specify the regional cord and size the AC circuit for the powered configuration.

What is the lifecycle status of SG350X-12PMV-K9-EU?

SG350X-12PMV-K9-EU is discontinued: end of sale was July 30, 2022, and its last date of support is July 31, 2027. The last Cisco shipment milestone was October 28, 2022. Retention plans should distinguish remaining hardware support eligibility from the already completed end-of-sale milestone.

What condition and warranty options does ORM Systems offer for SG350X-12PMV-K9-EU?

SG350X-12PMV-K9-EU is offered new sealed or certified refurbished. ORM warranties are up to 3-year extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. Cisco's limited lifetime hardware warranty is subject to eligibility and bounded by July 31, 2027.

What is the difference between SG350X-12PMV-K9-EU and SG350X-48PV-K9-EU?

SG350X-12PMV-K9-EU has a 375W shared PoE budget, whereas SG350X-48PV-K9-EU has 740W. Both models are discontinued. For existing installations, SG350X-12PMV-K9-EU corresponds to lower aggregate endpoint-power allocations, while SG350X-48PV-K9-EU accommodates a larger shared allocation. The decision depends on total allocated endpoint power rather than individual port ceilings.

What is the difference between SG350X-12PMV-K9-EU and SG350X-8PMD-K9-EU?

SG350X-12PMV-K9-EU provides four 10G uplink interfaces, while SG350X-8PMD-K9-EU provides two. Both models are discontinued, and neither gains extra uplinks from a removable card. SG350X-12PMV-K9-EU fits existing designs needing four uplink interfaces; SG350X-8PMD-K9-EU corresponds to designs needing only two, before reserving interfaces for stacking.

What is the difference between SG350X-12PMV-K9-EU and SG350X-24PV-K9-EU?

SG350X-12PMV-K9-EU has twelve access ports, while SG350X-24PV-K9-EU has twenty-four. Both models are discontinued. SG350X-12PMV-K9-EU suits replacement requirements involving twelve physical endpoint connections; SG350X-24PV-K9-EU corresponds to an existing installation requiring twenty-four connections. Count retained endpoints before choosing the replacement unit for either installed configuration.

What replaced the 12-port 5G PoE stackable managed switch?

CBS350-12NP-4X-EU replaced the SG350X-12PMV-K9-EU 12-port 5G PoE stackable managed switch, but CBS350-12NP-4X-EU is also discontinued and has no current successor. Its end-of-sale date was May 30, 2024, and support ends May 31, 2029. The replacement chain therefore does not identify a current orderable migration model.
