When replacing an installed SLM2048T-NA, this model is a named migration option. Before issuing the purchase order, reconcile the existing port assignments, connection media, and configuration requirements against the replacement order rather than treating the older model number as sufficient purchasing detail.
For a replacement-stock purchase, distinguish the spare-unit quantity from equipment intended for immediate installation. ORM certified refurbished units are inspected and bench-tested. Specify the required condition, staging allocation, and delivery region on the purchase order so receiving can separate operational spares from deployment stock.
Power delivery to connected endpoints
SG250-50-K9-NA does not supply PoE. For a current replacement purchase requiring powered access ports, C1200-48P-4G provides 48 Gigabit PoE ports and four 1G SFP uplinks.
10G uplinks to distribution
SG250-50-K9-NA has Gigabit uplinks rather than 10G connections. C1200-48T-4X provides 48 Gigabit access ports and four 10G SFP+ uplinks as a current alternative.

SG250-50-K9-NA identifies the Gigabit smart-switch model with 50 logical ports. The NA regional suffix covers the United States, Canada, Mexico, Colombia, Chile, and other designated Latin American markets.
SG250-50-K9-NA supports browser management, CLI over SSH or Telnet, SNMP, Smart Network Application, Cisco FindIT Network Manager, an embedded FindIT Network Probe, and Cisco Active Advisor.
Yes, SG250-50-K9-NA reached end of sale on October 30, 2021. Software maintenance ended October 30, 2022, and the last date of Cisco support is October 31, 2026. Remaining reseller inventory does not extend those milestones.
ORM Systems offers SG250-50-K9-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions have 30-day returns, terms apply. Cisco's limited lifetime hardware warranty is bounded by its October 31, 2026 support cutoff.
SG250-50-K9-NA is a named replacement for SLM2048T-NA, the SG200-50 Gigabit Smart Switch. For a new-generation purchase rather than an installed-base replacement, the forward migration chain now ends at C1200-48T-4G.
SG250-50HP-K9-NA supplies PoE, whereas SG250-50-K9-NA does not. Both are discontinued. The former addresses powered-endpoint requirements; the latter addresses independently powered devices when maintaining an existing installation.
SG250-50-K9-NA provides 50 logical Gigabit ports, while SG250-26-K9-NA provides 26. Both are discontinued; the larger model addresses higher connection counts, while the smaller model addresses lower-density installed-base replacements.
C1200-48T-4G provides four dedicated 1G SFP uplinks, while SG250-50-K9-NA uses two shared Gigabit copper/SFP uplinks. The former is the current migration destination; the latter addresses replacement requirements for existing SG250 installations.
No, each Cisco 250 combo port permits only one active connection at a time: copper or SFP. Specify the intended connection media before ordering optics or allocating copper uplink cables.
SG250-50-K9-NA uses an internal AC supply accepting 100-240V AC. Include the appropriate regional power connection in the receiving checklist rather than planning to power this model through an Ethernet uplink.
