SG350-28P-K9-NA is a managed Gigabit PoE+ switch with fixed uplinks for small-business networks. The 350 Series combines endpoint connectivity with configuration controls rather than requiring an unmanaged deployment. Specify the regional part number exactly on the purchase order, and distinguish access connections from shared copper/fiber uplink positions when preparing the port schedule.
SG350-28P-K9-NA price for new stock is is available on request. Get immediate quote. SG350-28P-K9-NA refurb price is $1,472.73.

56 Gbps switching capacity and 41.66 Mpps forwarding rate provide separate bandwidth and packet-processing limits. SG350-28P-K9-NA supports static routing and PBR; size the routing requirement before choosing this switch for inter-VLAN connectivity. Treat endpoint power allocation and electrical input demand as separate checks when preparing the installation.
Specify SG350-28P-K9-NA, quantity and new sealed or certified refurbished condition on the purchase order; refurbished units are inspected and bench-tested, every powered port has PoE output verified under load, and firmware is verified with configuration wiped to factory default. ORM Systems provides up to a 3-year extended warranty for new hardware, up to 1 year for certified refurbished hardware, and 30-day returns on every condition; terms apply. Cisco's separate limited lifetime warranty is bounded by October 31, 2026, so reseller coverage must not be mistaken for continuing Cisco service. For enterprise and volume orders, PO acceptance, Net-30 for government and RMA with advance replacement are available.

When an existing installation needs replacement stock, separate the required hardware condition from the quantity of operational spares. ORM Systems offers RMA with advance replacement and regional stock/RMA coverage across the UK, EU, US and MEA. Specify the destination, condition and spare quantity before issuing the purchase order.
When a government branch rollout requires purchase-order procurement, establish the delivery destinations and condition requirements before consolidating the order. ORM Systems accepts POs and offers Net-30 for government. Identify each site's required quantity and whether new sealed or certified refurbished hardware is required before submitting the purchase order.
Cisco support beyond October 2026
Cisco support ends October 31, 2026. For a replacement purchase requiring a current model, specify C1300-24P-4G rather than the discontinued intermediate successor CBS350-24P-4G-NA.
10G uplinks to distribution
The fixed uplinks are limited to Gigabit Ethernet. A requirement for 10G distribution connections falls outside this switch's uplink capabilities and must be resolved before ordering.

SG350-28P-K9-NA identifies the 28-port Gigabit PoE managed model; NA is its regional ordering suffix, including the United States. Keep the complete identifier on the PO rather than substituting a shortened model name.
The Cisco 350 Series supports a web UI, Textview CLI, SSH, Telnet, SNMP and Smart Network Application, plus FindIT Network Manager and Cisco Active Advisor integration. Select the intended administration method during staging.
SG350-28P-K9-NA reached end of sale October 30, 2021. Software maintenance ended October 30, 2022, and the last date of Cisco support is October 31, 2026. A reseller order does not restart those milestones.
ORM Systems offers SG350-28P-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty for new hardware and up to 1 year for refurbished hardware. Both conditions have 30-day returns; terms apply. Cisco's separate limited lifetime warranty is bounded by the October 31, 2026 support deadline.
SG350-28P-K9-NA replaces SG300-28PP-K9-NA. For an existing installation, confirm the required configuration and connected equipment before treating the newer hardware as an interchangeable spare. Keep both identifiers in the migration record to distinguish the retired unit from its replacement.
C1300-24P-4G has four dedicated 1G SFP uplinks, whereas SG350-28P-K9-NA includes shared copper/SFP uplink positions. The former is the current forward replacement; the latter is discontinued. Specify the uplink arrangement explicitly when choosing between maintaining an existing configuration and ordering its successor.
SG350-28P-K9-NA provides a shared 195W PoE budget. Prepare an endpoint power schedule before ordering; a powered-port count alone does not establish that every connected device can receive its maximum requested power simultaneously.
No, SG350-28P-K9-NA has fixed 1G uplinks. Do not specify this model against a purchase requirement for 10G distribution connectivity; resolve the uplink requirement before finalizing the equipment order.
C1300-24P-4G is the current forward replacement for SG350-28P-K9-NA. The original replacement, CBS350-24P-4G-NA, reached end of sale October 29, 2024. Avoid treating that discontinued intermediate model as the endpoint of a new replacement plan.
No, buying remaining new SG350-28P-K9-NA stock does not extend Cisco's October 31, 2026 support deadline. Separate the reseller's order coverage from manufacturer lifecycle support when reviewing the PO, and plan any required manufacturer-supported replacement independently of the hardware condition purchased.
