SG250-26HP-K9-NA is a Layer 2+ smart-managed Gigabit switch with 24 PoE+ access ports and two fixed Gigabit copper/SFP combo uplinks in a 1U rack chassis. The Cisco 250 Series Smart Switches serve small-business networks connecting computers, IP phones and wireless access points, with configurable switching features beyond unmanaged hardware. Each combo uplink supports either copper or fiber, but its copper connector and SFP slot cannot operate simultaneously. Compared with the discontinued SG250-26P-K9-NA and its 195W endpoint budget, this version accommodates a lower aggregate powered-device load. Voice VLAN support identifies telephone traffic separately, while configurable QoS assigns traffic priorities within a mixed endpoint network. The SG250-26HP combines those controls with fixed Gigabit connectivity rather than removable uplink cards or faster uplink interfaces.

52 Gbps switching capacity provides nonblocking switching, while 38.69 Mpps forwarding handles minimum-size packet traffic at wire speed. 100W of shared PoE capacity must be allocated across connected powered devices rather than treated as a full-power allowance for every port. Static IPv4 routing supports 32 routes and 16 IP interfaces for inter-VLAN communication; dynamic routing is not part of the feature set. SG250-26HP-K9-NA carries 512 MB of memory and 256 MB of flash, with 12 Mb of packet buffering shared across its ports. STP/RSTP/MSTP provide spanning-tree controls, and LACP supports four aggregation groups with eight active ports per group. Network segmentation can use 255 simultaneously active VLANs, while the MAC table accommodates 8000 addresses. Access control lists support 512 rules for filtering or rate limiting traffic, including time-based policies and application on ingress or egress. An IGMP querier can support a snooping domain when no multicast router is present.
SG250-26HP-K9-NA is available from ORM Systems new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units; returns are available for 30 days on every condition, terms apply. 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, quantity and required optics on the PO. For enterprise and volume orders, ORM accepts POs, offers Net-30 for government and provides RMA with advance replacement across UK, EU, US and MEA.

When a branch combines telephone, wireless and computer traffic, eight hardware queues support traffic prioritization with strict-priority or weighted round-robin scheduling. Auto Smartports can apply port roles using Cisco Discovery Protocol or LLDP-MED. Specify endpoint profiles, discovery settings and queue policies before releasing the purchase order.
For a repeatable multi-site rollout, text-editable configuration files can be transferred through SCP rather than recreated at each location. The scriptable Textview CLI supports privilege levels 1, 7 and 15. Specify configuration ownership, file-transfer access and the intended operator privileges before the purchase order.
When preparing a staged rollout or investigating application traffic, port mirroring can send four source ports to one destination port. Dual firmware images support upgrade staging while retaining another image. Include the analyzer connection, image selection and firmware acceptance checks in the staging plan before ordering the switch.
10G uplinks to distribution
The fixed copper/SFP combo uplinks operate at 1G. Installing a different optical transceiver does not turn these Gigabit interfaces into 10G uplinks.
More than 32 static IPv4 routes
IPv4 routing is limited to 32 static routes with 16 IP interfaces. A design exceeding either limit requires routing capacity beyond this switch.

SG250-26HP-K9-NA identifies a Gigabit Cisco 250 Series switch with 26 total ports: 24 PoE+ access ports and two copper/SFP combo ports. HP distinguishes the 100W version, and NA selects the Americas regional form, including the United States. K9 remains part of the complete ordering identifier.
SG250-26HP-K9-NA supports browser management over HTTP/HTTPS, Textview CLI over SSH or Telnet, and SNMP v1/v2c/v3. Additional management paths include Smart Network Application, Cisco FindIT Network Manager with an embedded FindIT Network Probe, and Cisco Active Advisor. Network Plug and Play supports automated provisioning rather than replacing local administration.
SG250-26HP-K9-NA provides a shared 100W PoE budget across 24 powered access ports, with a maximum of 30W on an individual port. The switch supports PoE+ and PoE endpoints. The shared budget prevents all powered ports from delivering their individual maximum simultaneously, so aggregate endpoint demand must be sized before ordering.
SG250-26HP-K9-NA has two fixed 1G copper/SFP combo uplinks, with only one medium active on each combo port. MGBSX1 supports multimode fiber connections, while MGBLX1 supports single-mode fiber connections. These are optical transceivers for fixed interfaces, not uplink expansion cards; order the required optics separately from the switch.
Cisco SG250-26HP supports static IPv4 routing with 32 routes and 16 IP interfaces, placing this configuration in the Layer 2+ category. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces. The routing feature set is static rather than a dynamic routing deployment.
SG250-26HP-K9-NA is discontinued: end of sale was October 30, 2021, and Cisco support ends October 31, 2026. Its named replacement, CBS250-24PP-4G-NA, is also discontinued, with end of sale on October 29, 2024. That replacement has no current migration product, so the replacement chain does not end at a current model.
ORM Systems offers SG250-26HP-K9-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is separate and bounded by the last support date, October 31, 2026.
SG250-26HP-K9-NA shares 100W across its PoE ports, whereas SG250-26P-K9-NA shares 195W. Both are discontinued models, so this distinction matters when matching a legacy spare. The lower-budget model fits smaller aggregate endpoint loads; the higher-budget version accommodates a larger total within its shared power allocation.
SG250-26HP-K9-NA uses an internal AC supply, while SG250-10P-K9 uses an external adapter and supports PoE input. Their powered access-port counts also differ: 24 versus eight. For legacy replacements, internal-power rack installations match the former configuration, while compact installations requiring external or PoE input match the latter.
SG250-26HP-K9-NA provides 24 Gigabit access ports, while SG250-50HP-K9-NA provides 48. Both retain two Gigabit copper/SFP combo uplinks and are discontinued. For legacy installations, the smaller configuration matches a 24-connection access requirement, while the larger chassis configuration suits buyers consolidating more copper endpoint connections into one switch.
Cisco SG250-26HP occupies one rack unit and measures 440 mm wide, 44 mm high and 257 mm deep, with a weight of 3.37 kg. A mounting kit is included in the original package. Check rack depth, cable clearance and required mounting hardware when specifying a replacement.
No, Cisco SG250-26HP uses one cooling fan rather than fanless cooling. Acoustic noise is 37.5 dB from 0°C to 30°C and 49.7 dB at 50°C. The operating temperature range is 0°C to 50°C, so account for fan noise when selecting an installation location near occupied work areas.
Cisco SG250-26HP requires 100-240V AC through its internal universal power supply, rather than an external adapter or PoE-powered uplink. Maximum consumption including PoE delivery is 135.2W at 110V. Use that whole-switch figure when planning AC circuits or backup power, rather than treating the endpoint power budget as total input demand.
