SG500X-48P-K9-NA is a managed, stackable Layer 2+ access switch with 48 Gigabit Ethernet PoE+ downlinks and four fixed 10G SFP+ connections in a 1U rack-mount chassis. The Cisco Small Business 500 family combines powered endpoint connectivity with faster aggregation links for small-business networks. IP phones, wireless access points, and surveillance cameras can use the powered connections, subject to the available power allocation. SG500X-48-K9 is the discontinued non-PoE sibling for installations where endpoints receive power separately. The SG500X-48P configuration uses built-in uplink cages rather than a removable uplink card, so no uplink expansion module is required. Local configuration remains available through the device's embedded management interfaces rather than depending on a hosted management service.

176 Gbps switching capacity supports the switching fabric, while 130.95 Mpps forwarding capacity defines the packet-handling ceiling. 375W of shared PoE power must be allocated across endpoint demand rather than treated as a maximum-power allowance for every port simultaneously. Static IPv4 and IPv6 routing plus RIPv2 support local routed segments; VRRP provides gateway redundancy. SG500X-48P-K9-NA carries 256 MB of DRAM and 32 MB of flash for embedded software and configuration storage. The 16384-entry MAC table bounds learned addresses. Support for 4096 VLANs and 3072 ACL rules establishes segmentation and packet-filtering limits. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection check address assignment and source bindings. The internal AC supply accepts 100–240V AC, and four fans provide active cooling rather than silent, fanless operation. Allow for 474W worst-case consumption when sizing rack power, not merely the endpoint power allocation.
ORM Systems offers SG500X-48P-K9-NA in new sealed and certified refurbished condition; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. Specify the required condition, included accessories, and quantities on the purchase order. ORM warranties provide up to 3-year extended coverage for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply, and Cisco service ended April 30, 2023. POs are accepted, government buyers can use Net-30, and enterprise or volume orders can include RMA with advance replacement across UK, EU, US, and MEA.

For an endpoint refresh retaining phones, wireless access points, or surveillance cameras, capture each device's requested power before committing the port schedule. Individual powered connections permit 30W, but that limit does not promise simultaneous maximum output. Size the combined endpoint load before completing the purchase order.
When extending an existing stack, reserve the two dual-purpose SFP+ connections for the intended stack topology instead of treating them as free uplinks. Ring and chain arrangements are supported. Add SFP-H10GB-CU1M, SFP-H10GB-CU3M, or SFP-H10GB-CU5M to the purchase order according to the required cable reach.
For a staged rollout across several locations, prepare a reference configuration and transfer it using SCP rather than rebuilding each switch manually. Text-editable configuration files support repeatable staging, while dual firmware images permit a retained software image. Specify the firmware baseline and configuration handling before ordering the batch.
Cisco-backed support for new deployments
Cisco service ended April 30, 2023, so this retired switch cannot satisfy an active manufacturer-support requirement. C1300-48P-4X is the current migration endpoint for replacement purchasing.
Multi-Gigabit copper endpoint connections
The copper downlinks stop at 1Gbps and cannot provide 2.5G or 5G access speeds. Faster uplink connections do not increase the native speed of those endpoint ports.
Fanless operation in occupied rooms
Four fans provide active cooling, so the chassis does not meet a fanless requirement for desks, meeting rooms, or other locations requiring passive cooling.

SG500X-48P-K9-NA identifies a 48-port Gigabit PoE+ stackable managed switch with four 10G SFP+ connections. SG500X identifies the Gigabit model group with 10G connections, 48 identifies the copper access-port count, and P identifies the powered configuration. Retain the complete K9-NA ending when specifying this exact item.
Cisco Small Business 500 management includes an HTTP/HTTPS web interface, Textview CLI through console or SSH/Telnet, and SNMP versions 1, 2c, and 3. FindIT provides device discovery, while legacy OnPlus integration is also present. The embedded web interface includes configuration, monitoring, maintenance, and a system dashboard.
SG500X-48P-K9-NA is retired, and Cisco support ended on April 30, 2023. The Small Business 500 family reached end of sale on April 12, 2018. A remaining-stock purchase therefore does not restore manufacturer support; condition and seller-backed coverage must be considered separately from the original product lifecycle.
ORM Systems offers SG500X-48P-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are 30 days for every condition; terms apply. Cisco's original limited lifetime hardware warranty no longer provides coverage: Cisco service ended April 30, 2023.
SG500X-48P-K9-NA provides a shared 375W PoE budget across 48 powered Gigabit ports, with a 30W maximum on an individual port. The shared allocation cannot supply every port at its individual maximum simultaneously. Add the intended endpoints' power requirements before assigning the final powered-port schedule.
SG500X-48P-K9-NA has four fixed 10G SFP+ connections, including two that can instead serve stacking. SFP-10G-SR and SFP-10G-LR provide multimode and single-mode fiber connections respectively. Reserve stacking connections before allocating uplinks, and include the required transceivers as separate purchase order lines rather than assuming optics are installed.
Cisco Small Business 500 hardware stacks support eight members with ring or chain topologies. Mixed SF500, SG500, and SG500X stacks are supported, with 5G copper connections between 500 and 500X members. For 10G copper connections between 500X members, select SFP-H10GB-CU1M, SFP-H10GB-CU3M, or SFP-H10GB-CU5M according to reach.
SG500X-48P-K9-NA supports static IPv4 and IPv6 routing, RIPv2 dynamic routing, and VRRP gateway redundancy. IPv4 static routing supports 2048 routes and 256 IP interfaces; IPv6 static routing supports 2048 routes and 128 interfaces. This combination provides routed access functionality without changing the physical Gigabit downlink configuration.
Yes, SG500X-48P-K9-NA uses a full-width rack-mount chassis measuring 440 mm wide, 44 mm high, and 350 mm deep. The unit weighs 5.74 kg and uses four fans. Its original package includes mounting hardware, a power cord, and a serial cable; specify required included items on the order.
SG500X-48P-K9-NA supplies PoE+ through its access ports, while SG500X-48-K9 does not supply endpoint power. Both belong to the discontinued Small Business 500 family. The powered model suits a legacy installation retaining Ethernet-powered endpoints; the non-PoE model suits equipment that already receives power independently of the network connection.
SG500X-48P-K9-NA provides 48 Gigabit copper access ports, whereas SG500X-24P-K9 provides 24. Both are discontinued powered models with fixed 10G SFP+ connections. The larger model addresses a legacy requirement for higher endpoint density; the smaller model fits an existing installation needing fewer copper access connections.
Cisco service for SG500X-48P-K9-NA ended April 30, 2023, while C1300-48P-4X is the current migration endpoint. The migration passes through discontinued CBS350-48P-4X hardware. Retain the older switch for a like-for-like legacy requirement; specify the current model when the purchase requires a supported replacement rather than retired equipment.
The Cisco Small Business 500 powered 500X configuration supports 4096 VLANs and 3072 ACL rules for segmentation and packet filtering. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection check address assignment and source bindings. RADIUS/TACACS+ authentication and protected management sessions provide additional controls for administrator access.
