Powered Access Networking for Small Business Offices

SG250-26P-K9-NA is a Layer 2+ smart managed switch with 24 Gigabit Ethernet PoE+ access ports and two fixed 1G copper/SFP combo uplinks in a 1U rack-mount chassis. Each combo connection supports either copper or fiber, with one medium active at a time; the uplink architecture does not include a removable network card. Part of Cisco 250 Series Smart Switches, this model connects and powers business endpoints including IP phones, wireless access points, and IP cameras. The discontinued SG250-26HP-K9-NA sibling carries a lower 100W PoE budget, distinguishing otherwise similar legacy installations. Separate access and combo uplink connections let the purchase order distinguish powered endpoint cabling from the network's copper or fiber handoff.

Technical Details

52 Gbps switching capacity provides nonblocking switching across the installed interfaces. 38.69 Mpps forwarding performance applies to 64-byte packets, providing a separate packet-processing measure for traffic sizing. 195W of shared PoE power must cover the connected endpoint load; individual powered ports support 30W until that allocation is reached. Static IPv4 routing supports 32 routes, setting the boundary for local inter-VLAN routing rather than dynamic route exchange. SG250-26P-K9-NA combines 512 MB of memory with 256 MB of flash for configuration and software operation. A dynamically shared 12 Mb packet buffer serves traffic across the ports. The 26-port Gigabit PoE switch also provides STP/RSTP/MSTP and LACP for loop control and aggregated links. HTTPS browser access and Textview CLI provide configuration paths, while SNMP v3 supports monitoring. An embedded FindIT Network Probe supports network management without requiring a separate probe host.

Ordering

ORM Systems offers SG250-26P-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition, terms apply. Certified refurbished 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 the condition and required optics on the purchase order. 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.

Buying Notes

Buying NotesKey Specs

Support window limits planning

SG250-26P-K9-NA requires support-limited procurement: sales ended October 30, 2021, and Cisco support ends October 31, 2026. C1200-24P-4G is the current successor; the intermediate CBS250-24P-4G-NA is also discontinued.

Optics require separate selection

Fiber connections require separately selected optics for SG250-26P-K9-NA. Specify MGBSX1 for multimode links up to 500 m or MGBLX1 for single-mode links up to 10 km, matching the remote interface.

Allocate endpoint power first

Endpoint power must be allocated before ordering SG250-26P-K9-NA: 24 × 30W equals 720W, exceeding the shared 195W budget. Specify each endpoint's maximum demand rather than assuming simultaneous full-power operation.

Best For

Routed Office Expansion

An office expansion that adds separate workgroups can use local static routing rather than sending every inter-VLAN exchange through an external router. The switch supports 16 IP interfaces, which constrains the routed interface plan independently of the physical connections. Check the required interface inventory before specifying the switch on the purchase order.

Voice Endpoint Rollout

A phone rollout creates a configuration requirement alongside the endpoint hardware order. Automatic voice VLAN functions and eight hardware queues support differentiated handling of voice traffic. Define the voice VLAN and traffic-priority policy before staging, then include the required endpoint configuration requirements with the purchase order.

Configuration Staging

A staging purchase for multiple locations can use text-editable configurations and SCP file downloads to prepare consistent settings before shipment. CLI privilege levels 1, 7, and 15 provide separate administrative access levels. Specify the configuration template, access credentials, and required staging checks before releasing the purchase order.

Not Suitable If

Four dedicated fiber uplinks

SG250-26P-K9-NA has two shared copper/SFP uplinks. C1200-24P-4G provides four 1G SFP uplinks while retaining 24 Gigabit access ports for a current-generation purchase.

Silent fanless operation

SG250-26P-K9-NA uses two cooling fans; installations requiring a chassis with no moving cooling components need a fanless switch instead.

Questions & Answers

What does the SG250-26P-K9-NA part number mean?

SG250-26P-K9-NA identifies a Cisco 250 Series Gigabit smart switch: 26 covers 24 access ports plus two combo uplinks, and P selects the 195W PoE+ configuration. NA is the regional suffix for the USA, Canada, Mexico, Colombia, Chile, and the rest of Latin America.

How are Cisco 250 Series Smart Switches managed?

Cisco 250 Series Smart Switches support HTTP/HTTPS web management, Textview CLI over SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager, embedded FindIT Network Probe, FindIT Network Discovery Utility, and Cisco Active Advisor. The CLI includes full and menu-based modes; browser management includes configuration wizards, monitoring, and a system dashboard.

Is SG250-26P-K9-NA end of sale?

Yes, SG250-26P-K9-NA reached end of sale on October 30, 2021, and its last date of Cisco support is October 31, 2026. Software maintenance ended October 30, 2022. Purchases should distinguish remaining hardware availability from the separate deadlines for software maintenance and eligible Cisco service.

What condition and warranty options does ORM Systems offer for SG250-26P-K9-NA?

ORM Systems offers SG250-26P-K9-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days for either condition; terms apply. Cisco's limited lifetime hardware warranty is bounded by October 31, 2026; fans and power supplies have a 1-year limited warranty.

How much PoE power does SG250-26P-K9-NA provide?

SG250-26P-K9-NA provides a shared 195W PoE budget across 24 PoE+ access ports, with a 30W maximum on an individual powered port. The budget does not support all powered ports drawing their individual maximum simultaneously. Endpoint power requirements must therefore be totaled before the switch is specified.

Which fiber uplinks can the Cisco SG250-26P use?

Cisco SG250-26P provides two 1G SFP connections that share their interfaces with copper combo ports. MGBSX1 supports multimode fiber up to 500 m, while MGBLX1 supports single-mode fiber up to 10 km. Only one medium per combo interface operates at a time, so copper and fiber are alternatives rather than additional simultaneous links.

Can SG250-26P-K9-NA route between VLANs?

Yes, SG250-26P-K9-NA supports static IPv4 routing between VLANs, with 32 static routes and 16 IP interfaces. Its routing capability is Layer 2+ rather than a dynamic-routing feature set. Check the required routes and routed interface count independently when planning how much local routing the switch will perform.

What power input and consumption does SG250-26P-K9-NA have?

SG250-26P-K9-NA uses an internal 100-240V AC power supply and reaches a maximum consumption of 262W at 110V with PoE load. Maximum consumption at 220V is 254.5W. These input-power figures include the powered configuration and should not be confused with the separate allocation available to endpoints.

Is the Cisco SG250-26P rack-mountable?

Yes, Cisco SG250-26P is a 1U rack-mount switch measuring 440 mm wide, 44 mm high, and 257 mm deep, with a weight of 3.81 kg. A mounting kit is included in the original package. Check rack depth and the mounting hardware included with the selected condition before ordering.

What is the difference between SG250-26P-K9-NA and SG250-26HP-K9-NA?

SG250-26P-K9-NA supplies a 195W PoE budget, compared with 100W on SG250-26HP-K9-NA. Both configurations have 24 Gigabit PoE+ access ports and two Gigabit combo uplinks. Both are discontinued: the first suits legacy requirements needing the larger power allocation, while the second matches existing lower-budget installations.

What is the difference between SG250-26P-K9-NA and SG250-50P-K9-NA?

SG250-26P-K9-NA has 24 Gigabit access ports, whereas SG250-50P-K9-NA has 48. Both models are discontinued and include two Gigabit copper/SFP combo uplinks. The smaller model matches lower-density legacy requirements; the larger model addresses installations that need more physical endpoint connections within the same switch purchase.

What is the difference between SG250-26P-K9-NA and C1200-24P-4G?

SG250-26P-K9-NA has two shared Gigabit copper/SFP uplinks, while C1200-24P-4G has four Gigabit SFP uplinks. C1200-24P-4G is the current successor after the discontinued CBS250-24P-4G-NA. The older switch matches exact legacy replacement requirements; the current successor suits buyers requiring four fiber uplinks without shared copper interfaces.
