When replacing an existing SF550X-24MP-K9-NA installation, the Gigabit replacement changes the access connection speed from the predecessor’s 10/100 interfaces. Treat the discontinued hardware as a maintenance purchase rather than an open-ended standard, and confirm the intended replacement scope before issuing the purchase order.
Where an existing 550X installation needs another member, ring and chain arrangements provide different interconnection layouts. Reserve the required interfaces before allocating remaining connections to other equipment. Specify the existing member models, intended topology and interconnection media on the purchase request before finalizing the order.
Ongoing vendor software maintenance
Software maintenance ended on July 30, 2023. For a new installation requiring a current migration model, specify C1300-24FP-4X rather than this discontinued switch.
Four simultaneous copper 10G uplinks
Only two uplink connections offer copper interfaces. The remaining dedicated uplinks use SFP+ cages, so four simultaneous copper uplinks are not available.

SG550X-24MP-K9-NA identifies a Gigabit 550X switch: 24 denotes the access-port count, MP distinguishes the 382W PoE configuration, and NA selects the regional ordering form covering the United States, Canada, Mexico and other listed American markets.
SG550X-24MP-K9-NA supports HTTP/HTTPS browser management, console CLI, SSH, Telnet, SNMP, Smart Network Application, Cisco FindIT Network Manager and Active Advisor. The CLI supports scripting as well as full-command and menu interfaces.
SG550X-24MP-K9-NA is discontinued: end of sale was July 30, 2022, software maintenance ended July 30, 2023, and the last date of support is July 31, 2027. Purchases should account for these fixed lifecycle boundaries.
ORM offers SG550X-24MP-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are available for 30 days on every condition; terms apply. Cisco’s limited lifetime hardware warranty is bounded by July 31, 2027.
SG550X-24MP-K9-NA replaces SF550X-24MP-K9-NA, whose end-of-sale date was June 18, 2020. The predecessor provided 10/100 access connections; the replacement provides Gigabit access. Both models are discontinued, so this is a legacy migration relationship rather than a current-generation recommendation.
SG550X-24MP-K9-NA provides PoE, whereas SG550X-24-K9-NA does not. Both are discontinued. The powered model suits maintenance of installations supplying endpoint power through Ethernet; the non-PoE model suits legacy installations whose endpoints receive power separately.
SG550X-48P-K9-NA provides 48 Gigabit access ports, compared with 24 on SG550X-24MP-K9-NA. Both are discontinued. The former addresses higher connection density in an existing installation; the latter suits a legacy purchase requiring fewer access connections.
C1300-24FP-4X provides four 10G SFP+ uplinks, whereas SG550X-24MP-K9-NA combines dedicated SFP+ and copper/SFP+ combo uplinks. C1300-24FP-4X is the current migration endpoint; the discontinued 550X model addresses maintenance of existing installations.
The 550X 24-port MP switch supports 60W on eight selected ports and 30W on the remaining powered ports. The shared PoE budget limits simultaneous endpoint loading; 60W capability does not mean every port can supply that amount.
A 550X hardware stack contains a maximum of eight members. Standard fiber or copper connections provide the stack interconnects, and ring or chain topologies are supported. Allocate interconnection interfaces before assigning the remaining connections to other equipment.
