SX350X-08-K9-NA is a managed 350X Series 10G copper switch for small-business racks that need Layer 2+ switching with static routing at the access or compact aggregation edge. The SX350X-08 hardware provides 6 fixed 10G RJ-45 access ports, 2 fixed 10G copper/SFP+ combo uplinks and a dedicated 1G out-of-band management port in a 1U chassis. The combo uplinks support copper or SFP+ media, with one side of each combo pair active at a time, so optics and direct-attach cables are planned separately. This 8 Port 10GBase-T Stackable Managed Switch is non-PoE and fits powered servers, storage, firewalls and upstream switch links rather than endpoint power delivery. SX350X-12-K9-NA raises the copper configuration to 12 10GBase-T ports while keeping two combo SFP+ ports.

160 Gbps switching capacity and 119.05 Mpps forwarding support wire-speed, nonblocking traffic across the 10G copper and combo uplink layout. Static IPv4 routing supports up to 990 routes, static IPv6 routing supports up to 245 routes, and Layer 3 interfaces can be configured on physical ports, LAGs, VLAN interfaces or loopback interfaces. The Cisco 350X Series Stackable Managed Switches support STP/RSTP/MSTP, LACP, VLANs, IGMP snooping, IGMP querier, UDLD, GVRP/GARP, Q-in-Q and Selective Q-in-Q for Layer 2 designs. SX350X-08-K9-NA carries 32000 MAC addresses, 512 MB memory, 256 MB flash and a 3 MB shared packet buffer. Management is available through the browser GUI, Smart Network Application, FindIT Network Manager and Probe, FindIT Discovery Utility, SNMPv3, SSH, Telnet, console and the dedicated OOB port. Hardware stacking supports 4 units and hybrid stacks across SG350X, SG350XG and SX350X models. Maximum system power consumption is 50.3W from internal universal AC power.
Order SX350X-08-K9-NA as new sealed hardware or certified refurbished inventory, matched to the condition requirement on the PO. Refurbished units are inspected and bench-tested; managed units are firmware verified, wiped to factory default, and checked for power-on and POST, 10G port links, optics bay recognition, fan status and PSU status. New units can carry up to a 3-year extended warranty, certified refurbished units can carry up to 1 year, and returns are 30 days on every condition with terms applying. PO is accepted, Net-30 is available for government accounts, RMA with advance replacement is available, and regional stock/RMA coverage includes UK, EU, US and MEA.

Replacement PID | CBS350-8XT-NA, no further migration |
A small rack with copper-attached servers or storage can use 6 fixed 10G RJ-45 access ports while reserving the 2 combo uplinks for copper or SFP+ handoff. Before the PO, specify the required SFP-10G-SR=, SFP-10G-LR= or direct-attach cable PIDs separately.
An installed 350X stack can add another 10G member when the design stays within the 4-unit hardware-stack limit and allows SG350X, SG350XG and SX350X mixing. Count the 10G interfaces assigned to stack interconnects before treating combo ports as available uplinks.
A site standardized on 350X firmware can keep a same-series spare for swap consistency before the 31 July 2027 Cisco support endpoint. Record the unit condition, firmware baseline and factory-default requirement on the PO so staging matches the installed stack.
PoE endpoint power
SX350X-08-K9-NA provides no PoE on its RJ-45 network ports. The 8-port PoE migration path ends at CBS350-8MP-2X-NA, which has no migration product.
Dynamic routing protocols
SX350X-08-K9-NA supports static IPv4 and IPv6 routing only. Use a Layer 3 platform when OSPF, BGP, EIGRP or IS-IS is required.
Dedicated SFP+ uplinks
The 2 SFP+ cages share combo ports with copper, with one side active per combo. The SX350X-52 path ends at discontinued CBS350-48XT-4X-NA with no migration product.
Redundant internal power
SX350X-08-K9-NA uses one internal universal AC power input and no redundant PSU. Select a platform with redundant supplies if power-supply resiliency is mandatory.

SX350X-08-K9-NA is the North America orderable PID for the SX350X-08 model in the 350X series. SX350X-08 identifies the 8-port 10GBase-T stackable managed switch, K9 is part of the product order ID, and -NA is the USA, Canada, Mexico, Colombia, Chile and rest-of-LATAM region suffix.
SX350X-08-K9-NA is managed through the browser GUI, Smart Network Application, FindIT Network Manager and Probe, FindIT Discovery Utility, SNMPv3, and CLI access over SSH or Telnet. It also has a Cisco standard RJ-45 console port and a dedicated 1G out-of-band management port.
SX350X-08-K9-NA is end-of-sale, with Cisco's last order date on 30 July 2022 and last date of support on 31 July 2027. Cisco names CBS350-8XT-NA as the replacement, and that replacement is also end-of-sale with no migration product available.
ORM Systems offers SX350X-08-K9-NA new sealed or certified refurbished. Cisco's limited lifetime hardware warranty is bounded by the 31 July 2027 last date of support; ORM offers up to 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns with terms applying.
SX350X-08-K9-NA has 6 fixed 10G copper access ports and 2 10G copper/SFP+ combo uplinks, plus a dedicated 1G out-of-band management port. The combo pairs share copper and SFP+ sides, so only one side of each combo port is active at a time.
No, SX350X-08-K9-NA does not provide PoE, PoE+ or 60W PoE on its RJ-45 network ports. Use this model for externally powered copper endpoints, servers or uplinks that do not need switch-supplied power, and choose a PoE model when endpoint power is required.
SX350X-08-K9-NA supports hardware stacking with up to 4 units in one stack. The 350X stack can mix SG350X, SG350XG and SX350X switches, and the stack uses 10G copper or fiber interfaces as the interconnect rather than dedicated stack ports.
SX350X-08-K9-NA is a Layer 2+ switch with static IPv4 routing up to 990 routes and static IPv6 routing up to 245 routes. OSPF, BGP, EIGRP and IS-IS are not part of its routed feature set, so dynamic routing should be handled elsewhere.
The 350X series combo SFP+ ports support 10G options including SFP-10G-SR=, SFP-10G-LR=, SFP-10G-SR-S=, SFP-10G-LR-S=, SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M=. Copper and SFP+ sides of a combo pair are shared, so plan either media type per combo.
SX350X-08-K9-NA is a rack-mount 1U switch with a 440 mm width, 44 mm height and 203 mm depth. A mounting kit is included with all 350X models, and the switch uses internal universal 100-240V AC power rather than an external adapter.
No, SX350X-08-K9-NA uses internal universal 100-240V AC power and no redundant PSU is provided. Its worst-case system power consumption is 50.3W at either 110V or 220V, with fan and PSU status included in managed refurbished-unit checks.
SX350X-12-K9-NA carries 12 10GBase-T copper ports where SX350X-08-K9-NA carries 8 10GBase-T copper ports. Choose SX350X-08-K9-NA for the smaller copper footprint, while SX350X-12-K9-NA fits an installed 350X rack needing four additional 10G copper connections.
SX350X-24F-K9-NA provides 24 SFP+ ports with 4 copper/SFP+ combo ports, while SX350X-08-K9-NA provides 8 10GBase-T copper ports with 2 SFP+ combo ports. Use SX350X-08-K9-NA for copper 10GBase-T runs and SX350X-24F-K9-NA for an installed 350X fiber-heavy rack.
CBS350-8XT-NA is the named replacement for SX350X-08-K9-NA and is described as an 8-port 10GE switch with 2 shared 10G SFP+ ports. SX350X-08-K9-NA fits installed 350X stack standardization, while CBS350-8XT-NA follows the migration path but is also discontinued.
