SG250-50HP-K9-NA is a smart-managed Layer 2+ switch with 48 Gigabit PoE+ access ports and two fixed Gigabit copper/SFP combo uplinks. Each combo connection uses either copper or fiber, not both simultaneously. The rack-mount 1U chassis belongs to Cisco 250 Series Smart Switches and serves small-business computers, phones, wireless access points, and surveillance endpoints. The discontinued SG250-50P-K9-NA sibling provides a larger 375W endpoint power allocation. The SG250-50HP combines powered access connections with traffic segmentation and prioritization rather than an enterprise chassis or interchangeable uplink cards. Browser-based configuration and network-level management tools support administration of the business network, while the fixed uplink arrangement determines the media to specify for connections beyond the local access ports.

100 Gbps switching capacity provides nonblocking forwarding across the installed connections. 74.41 Mpps forwarding performance is rated with 64-byte packets. 192W of shared PoE power limits the combined allocation to connected endpoints, independently of the number of powered ports in use. Static IPv4 routing supports 32 routes and 16 IP interfaces for communication between configured network segments; dynamic routing is outside this static-routing feature set. SG250-50HP-K9-NA has 512 MB of DRAM and 256 MB of flash for its embedded software and configuration storage, with a dynamically shared 24 Mb packet buffer across the ports. STP/RSTP/MSTP handle spanning-tree operation, while LACP supports four aggregation groups with eight active ports per group. Segmentation supports 255 simultaneously active VLANs. Eight hardware queues provide traffic prioritization through strict-priority or weighted round-robin scheduling. IPv6 access controls can drop or rate-limit traffic, and multicast snooping restricts delivery to requesting receivers.
ORM Systems offers SG250-50HP-K9-NA new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year; Cisco's limited lifetime hardware warranty is subject to eligibility and ends by October 31, 2026. Refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links, clean boot, PoE output under load on every powered port, optics recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify condition, quantity, and optics on the PO; both conditions carry 30-day returns, with terms applying. For enterprise and volume orders, ORM accepts POs, provides Net-30 for government, and offers RMA with advance replacement across UK, EU, US, and MEA.

When replacing discontinued SLM2048PT-NA hardware, this model follows the original migration path for the older Gigabit PoE smart switch. The predecessor reached end of sale on October 4, 2018. Reconcile the installed regional identifier and existing connection media, then specify the replacement condition and required accessories on the purchase order.
When several business sites need a common configuration, text-editable configuration files and SCP autoconfiguration support a repeatable staging workflow. DHCP options 12, 66, 67, 129, and 150 support centralized provisioning tasks. Identify the site-specific addressing and provisioning parameters, then specify the configuration handling required before shipment.
When a purchase includes hardware for software validation, dual firmware images and the front-panel USB Type-A connection support image and configuration handling during staging. CLI privilege levels 1, 7, and 15 separate operator access. Define the candidate image, retained configuration, and administrator access requirements before issuing the purchase order.
10G uplinks to distribution
The fixed combo uplinks operate at 1G. C1200-48P-4X provides 48 Gigabit access ports and four 10G SFP+ uplinks for a purchase requiring faster upstream connections.
Endpoint loads above the shared budget
The combined endpoint power allocation stops at 192W, despite PoE+ support across the access ports. A higher aggregate powered-device load cannot be specified against this switch's available PoE allocation.
Dynamic routing between business networks
IPv4 routing supports 32 static routes and 16 IP interfaces. A deployment requiring dynamically exchanged routes exceeds the static-routing capability of this switch.

SG250-50HP-K9-NA identifies a Gigabit smart switch in the 250 family: 50 total network ports, the HP PoE+ configuration with a 192W budget, and the NA regional variant. K9 remains part of the complete ordering identifier. NA covers the United States, Canada, Mexico, Colombia, Chile, and remaining Latin America.
SG250-50HP-K9-NA supports browser management through HTTP/HTTPS, a full or menu-based CLI over SSH/Telnet, and SNMP versions 1, 2c, and 3. Network-level tools include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, FindIT Network Discovery Utility, and Cisco Active Advisor.
SG250-50HP-K9-NA is discontinued: Cisco end of sale was October 30, 2021, and the last date of support is October 31, 2026. Software maintenance ended October 30, 2022. Purchasing remaining new or refurbished hardware does not restart the manufacturer's maintenance or support schedule.
ORM Systems offers SG250-50HP-K9-NA new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions carry 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is subject to eligibility and bounded by October 31, 2026, with 1-year fan and power-supply coverage.
SG250-50HP-K9-NA replaced discontinued SLM2048PT-NA, also sold as SG200-50P, whose end-of-sale date was October 4, 2018. The older unit's Cisco support ended October 31, 2023. Match the complete regional part number when reconciling installed inventory or specifying a replacement against an existing purchase-order line.
SG250-50HP-K9-NA provides a shared 192W PoE budget across 48 powered access ports, with a maximum of 30W available to an individual port. All powered endpoints draw from the same allocation. The switch cannot supply every powered port at its individual maximum simultaneously, so endpoint demand must be sized collectively.
SG250-50HP has two fixed 1G copper/SFP combo uplinks, with one medium active per combo connection. MGBSX1 supports multimode fiber links to 500 m, while MGBLX1 supports single-mode fiber links to 10 km. Order the chosen transceivers separately and match the fiber type and remote connection.
The 250 smart switch supports static IPv4 routing between configured network segments, with 32 static routes and 16 IP interfaces. Routing interfaces can use a physical port, aggregation group, VLAN interface, or loopback interface. DHCP relay is also supported; a design requiring dynamic route exchange exceeds this static-routing feature set.
SG250-50HP-K9-NA uses an internal universal AC supply accepting 100-240V at 50-60 Hz. The package includes a power cord and mounting kit. Worst-case consumption with PoE is 267.2W at 110V or 263.5W at 220V, so reserve AC capacity for the complete powered system rather than only the endpoint budget.
SG250-50HP-K9-NA was replaced by CBS250-48PP-4G-NA, but that replacement is also discontinued and has no current migration product. CBS250-48PP-4G-NA reached end of sale on October 29, 2024, with support ending October 31, 2029. A new hardware requirement therefore needs a separate selection rather than treating the historical successor as current.
SG250-50P-K9-NA provides a 375W PoE budget, whereas SG250-50HP-K9-NA provides 192W. Both variants are discontinued. For existing hardware standards, the P model accommodates a larger aggregate powered-device load; the HP model suits an endpoint inventory that remains within its smaller shared allocation.
SG250-26HP-K9-NA has 24 dedicated Gigabit access ports, whereas SG250-50HP-K9-NA has 48. Both are discontinued members of the 250 family. The 24-port model addresses smaller legacy port inventories; the 48-port version suits purchase orders requiring higher endpoint density without dividing the access connections across additional switches.
SG250X-48P-K9-NA provides four 10G uplinks, comprising two copper connections and two SFP+ connections, whereas SG250-50HP-K9-NA provides two 1G combo uplinks. Both models are discontinued. The X model serves an existing 10G upstream requirement; the HP model fits legacy connections that remain at Gigabit speed.
