SG550X-48MP-K9-NA combines 48 Gigabit PoE+ access ports with four fixed 10G uplinks in a managed, stackable switch. Two uplink positions offer shared 10GBASE-T/SFP+ connections, while two provide dedicated SFP+ connections; each shared position uses either copper or fiber at one time. The Cisco 550X Series serves small and medium businesses connecting powered endpoints and aggregating access traffic. Its Layer 2+ capabilities add inter-VLAN routing to Ethernet switching, and the 1U chassis includes a mounting kit for an equipment rack. Compared with the discontinued SG550X-48P-K9-NA, this model provides a larger allocation for endpoint power. An internal universal AC supply powers the chassis, while an external RPS2300 system provides the supported power-redundancy approach rather than a second internal supply.

176 Gbps switching capacity supports nonblocking forwarding across the access and uplink interfaces. 130.94 Mpps forwarding handles 64-byte packets at the published maximum rate. 740W of shared PoE capacity must accommodate the connected endpoint load: sixteen powered ports support 60W, and the remaining powered ports support 30W, subject to that total allocation. Static routing, RIP v2, VRRP v2/v3 and PBR provide routing and gateway-control functions without an enterprise network-license tier. SG550X-48MP-K9-NA combines 512 MB of DRAM with 256 MB of flash for control-plane operation and software storage. A dynamically shared 3 MB packet buffer accommodates traffic bursts across the ports. The forwarding resources include 16000 MAC entries and 7168 IPv4 routes. Administrators can configure the switch through its HTTP/HTTPS interface or Textview CLI, with SSH available for remote command-line sessions. STP/RSTP/MSTP and LACP provide loop control and link aggregation, while eight hardware queues support traffic scheduling.
Specify SG550X-48MP-K9-NA in new sealed or certified refurbished condition, with the required optics and quantities on the purchase order.

When adding routed interfaces to an existing access network, the 256 IPv4 interface limit affects how VLAN interfaces, physical interfaces and aggregated links are assigned. Inventory the interfaces required by the planned configuration before selecting quantities, and include the interface allocation and gateway configuration requirements with the purchase order.
When extending an existing 550X stack, cable reach and front-panel port allocation need review before another member is ordered. SFP-H10GB-CU3M provides a supported 3 m direct-attach connection. Choose the ring or chain arrangement, reserve the interconnect ports, and specify the required cable quantities alongside the switch.
During a multi-site standardization purchase, policy templates need to fit the switch's 3000 ACL entries. Text-editable configuration files and SCP downloads support reuse across sites, but rule counts still need review for each location. Include the approved configuration baseline and site-specific ACL requirements with the hardware purchase order.
Maximum power on every port simultaneously
SG550X-48MP-K9-NA shares 740W across its powered ports, so every port cannot deliver its individual maximum simultaneously. Endpoint demand and power priorities must fit the aggregate budget.
Dedicated out-of-band Ethernet management
SG550X-48MP-K9-NA has an RJ-45 console connection but no dedicated out-of-band Ethernet management port. Remote network management uses the switching interfaces rather than a separate management interface.
Hardware still orderable directly from Cisco
SG550X-48MP-K9-NA ended sale on July 30, 2022. C1300-48FP-4X is the current successor, retaining 48 Gigabit powered access ports and four 10G SFP+ uplinks.

SG550X-48MP-K9-NA identifies a 550X managed Gigabit switch: SG550X identifies the Gigabit model group, 48 identifies the access-port count, and MP selects the PoE+ configuration with a 740W budget. NA identifies the regional version for the United States, Canada, Mexico, Colombia, Chile and remaining Latin America.
SG550X-48MP-K9-NA supports an HTTP/HTTPS web interface, Textview CLI through console, SSH or Telnet, SNMP, Smart Network Application, and FindIT Network Manager with an embedded FindIT Network Probe. FindIT Network Discovery Utility supports discovery, and Active Advisor is also supported. The CLI offers full and menu interfaces.
SG550X-48MP-K9-NA reached end of sale on July 30, 2022, and its last date of support is July 31, 2027. Software maintenance releases ended on July 30, 2023. Purchases therefore need to distinguish remaining hardware availability from ongoing software maintenance and the remaining Cisco support period.
ORM Systems offers SG550X-48MP-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. Both conditions include 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is bounded by July 31, 2027, the last date of support.
SG550X-48MP-K9-NA replaces the discontinued SF550X-48MP-K9-NA, which reached end of sale on June 18, 2020. The older model provides 48 Fast Ethernet access ports, whereas the replacement provides Gigabit access ports. Match the existing installation's copper access-speed requirements when identifying the replacement hardware for an older deployment.
SG550X-48MP-K9-NA provides a shared 740W PoE budget across 48 powered access ports, including sixteen ports capable of 60W and thirty-two capable of 30W. Individual port maxima remain subject to the total budget. Size the connected endpoint load and assign power priorities before assuming all powered devices can operate together.
SG550X-48MP-K9-NA provides four 10G uplink positions: two dedicated SFP+ connections and two shared 10GBASE-T/SFP+ connections. A shared position activates only one medium at a time. Supported fiber options include SFP-10G-SR for multimode links and SFP-10G-LR for single-mode links; specify optics separately from the chassis.
Cisco 550X hardware stacking supports eight members managed as one system, using standard 10G copper or fiber interfaces rather than dedicated stack connectors. Ring and chain arrangements are supported. Compatible direct-attach cables include SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M; allocate ports for stacking before assigning uplinks.
The Cisco 550X Series provides IPv4 routing, IPv6 static routing, RIP v2, VRRP v2/v3 and PBR. The IPv4 routing capacity is 7168 routes with 256 IP interfaces, while IPv6 static routing supports 1792 routes. Treat routing-table capacity and interface capacity as separate limits when preparing the configuration.
SG550X-48MP-K9-NA provides a 740W PoE budget, while SG550X-48P-K9-NA provides 382W. Both models are discontinued and have 48 Gigabit powered access ports. The MP configuration suits an existing installation requiring a larger endpoint-power allocation; the P configuration corresponds to installations sized around the smaller shared budget.
SG550X-48MP-K9-NA has 48 Gigabit access ports, while SG550X-24MP-K9-NA has 24 Gigabit access ports. Both models are discontinued. The 48-port chassis matches denser existing access installations, while the 24-port chassis matches smaller port requirements; use this comparison to identify the required density when matching installed 550X hardware.
SG550X-48MP-K9-NA has two dedicated SFP+ uplinks and two shared copper/SFP+ uplinks, while C1300-48FP-4X has four SFP+ uplinks. The discontinued 550X model corresponds to existing deployments using its shared-media connections. C1300-48FP-4X is the current successor for buyers standardizing on four optical uplink positions in a new purchase.
