SG500X-48MP-K9-NA combines 48 Gigabit PoE+ access ports with four fixed 10G SFP+ uplinks in a managed Layer 2+ switch. The 1U rack chassis belongs to the Cisco 500X Series within the Small Business switching family, connecting wired users and powered endpoints. The discontinued SG500X-48P-K9 is the lower-power PoE+ sibling, retaining the same access-port density and uplink format. Cisco SG500X-48MP supports voice-specific VLAN treatment for IP phones alongside traffic segmentation for other business devices. Its fixed uplink architecture requires no removable uplink card, keeping the chassis configuration consistent when matching retained equipment or assembling replacement hardware for an existing installation.

176 Gbps switching capacity supports wire-speed operation, while 130.95 Mpps forwarding handles minimum-size packets. Static IPv4 and IPv6 routing provide local subnet connectivity, and RIP v2 supplies dynamic route exchange; VRRP v2 and VRRP v3 support redundant default gateways. The IPv4 routing limit is 2048 static routes, with 256 IP interfaces available for segmentation. SG500X-48MP-K9-NA carries 256 MB of memory and 32 MB of flash for its embedded software and configuration storage. A 16384-entry MAC table accommodates learned endpoint addresses. STP/RSTP/MSTP control switching loops, while LACP supports aggregated links. Management includes a browser interface and command-line access, allowing configuration through graphical or text-based workflows. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection check addressing information against learned bindings. Four fans provide active cooling, so installation planning must accommodate a fan-cooled chassis rather than a silent desktop unit.
Specify SG500X-48MP-K9-NA in new sealed or certified refurbished condition on the PO, with the required connection accessories itemized. Certified refurbished units are inspected and bench-tested, with every port linked at rated speed, every powered port verified under load, firmware verified, and the configuration wiped to factory default. ORM's new-unit warranty is up to 3 years extended and certified refurbished warranty is up to 1 year; returns are 30 days on every condition, terms apply, while Cisco's original limited lifetime hardware warranty ended April 30, 2023. Enterprise and volume POs are accepted, with Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US, and MEA.

An existing Small Business 500 stack needs another member while retaining its management arrangement. Native 500X connections support 10G stacking, while mixed connections to SF500 or SG500 support 5G copper stacking. Ring and chain arrangements are available; verify partner families, connection speed, and topology before adding the unit to the PO.
A replacement hardware batch needs configuration work completed before shipment to individual sites. Dual software images support staged firmware handling, and configuration files can be edited as text before transfer. Include the required console connection in the staging plan, then specify firmware verification and factory-default delivery requirements on the purchase order.
A branch rollout needs separate address domains for business devices rather than a single flat network. Support for 4096 simultaneous VLANs provides segmentation capacity, while the embedded IPv4 DHCP server can assign addresses from multiple pools. Establish the VLAN plan and address scopes before specifying configuration work with the hardware order.
Active Cisco hardware support
Cisco support ended April 30, 2023, so manufacturer service is no longer available for this model. C1300-48FP-4X is the current destination of its replacement chain.
More than 30W per endpoint
Each powered RJ-45 port supplies a maximum of 30W. Endpoints requiring more power per connection exceed this switch's delivery capability, regardless of the remaining shared PoE allocation.
Fanless equipment operation
Four internal fans provide active cooling, so the chassis does not satisfy a fanless equipment requirement. Its published acoustic output is 46.4 dB.

SG500X-48MP-K9-NA identifies a Gigabit 500-family switch with 10G uplinks and 48 Max-PoE ports. S means switch, G means Gigabit, 500 identifies the family, X denotes 10G uplinks, and MP denotes Max-PoE. K9 identifies high encryption; NA specifies the Americas/Taiwan power-plug region, using Type A or Type B plugs.
SG500X-48MP-K9-NA supports an HTTP/HTTPS web interface, full or menu-based CLI through console, SSH or Telnet, and SNMP v1/v2c/v3. The browser interface includes a local system dashboard. Historical Cisco Small Business and Cisco OnPlus cloud integrations do not restore Cisco service coverage for this retired hardware.
SG500X-48MP-K9-NA is retired: end of sale was April 12, 2018, and Cisco support ended April 30, 2023. Manufacturer service has ended regardless of the original hardware warranty term. The replacement chain passes through discontinued 550X and Business 350 hardware to C1300-48FP-4X.
SG500X-48MP-K9-NA is offered new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. ORM Systems provides 30-day returns on either condition; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on April 30, 2023.
No, SG500X-48MP-K9-NA shares 740W across its 48 PoE+ ports, so every port cannot draw 30W simultaneously. A full 48-port allocation at 30W would require 1440W. Size the connected endpoint load against the shared budget rather than multiplying the per-port maximum into an available-power assumption.
Cisco SG500X-48MP supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber in its 10G SFP+ interfaces. SFP-10G-SR supports distances up to 400 m, while SFP-10G-LR supports 10 km. Specify the optic PID, fiber type, and required connection distance together when preparing the order.
SG500X-48MP-K9-NA supports hardware stacks of eight members with unified management. Ring and chain arrangements are available, and stack connections can use SFP-H10GB-CU1M, SFP-H10GB-CU3M, or SFP-H10GB-CU5M. The stacking interfaces share SFP+ resources with uplinks, so reserve those connections before committing the external uplink arrangement.
SG500X-48MP-K9-NA supports static IPv4 and IPv6 routing, RIP v2 dynamic routing, and VRRP v2/v3 gateway redundancy. IPv4 static routing supports 2048 routes and 256 IP interfaces; IPv6 static routing supports 2048 routes and 128 interfaces. These capabilities support subnet connectivity without implying a broader enterprise routing feature set.
SG500X-48MP-K9-NA provides a 740W PoE budget, while SG500X-48P-K9 provides 375W. The larger shared allocation accommodates a higher combined powered-endpoint load without changing the per-port PoE+ limit. Both are discontinued; the higher-budget model suits retained installations with greater power demand, while the lower-budget sibling fits smaller aggregate loads.
SG500X-48MP-K9-NA supplies 48 Gigabit access ports, whereas SG500X-24MPP-K9 supplies 24. Access-port density is the purchasing distinction when matching these discontinued models to an existing installation. The 48-port unit suits a larger wired endpoint count; the 24-port sibling suits an installation requiring fewer access connections.
SG500X-48MP-K9-NA has ended Cisco support, while C1300-48FP-4X is the current destination of its replacement chain. The original model is a retained-generation purchase rather than a route to renewed manufacturer coverage. Existing-equipment matching favors the legacy unit; a supported-generation refresh should specify the current successor instead.
