SG500X-48-K9 provides 48 Gigabit Ethernet access ports and four fixed 10G SFP+ connections in a managed, non-PoE, rack-mounted switch. The 500X combines Layer 2 switching with static routing and RIP v2, placing it in the Layer 2+ category rather than a full enterprise routing tier. Two SFP+ connections can serve as stacking links, so the uplink allocation depends on whether the unit operates independently or joins a stack. The Cisco 500 Series Stackable Managed Switches family targets small-business networks needing centralized configuration across multiple switches. The discontinued SG500X-48P-K9 differs by adding PoE+ with a shared 375W endpoint-power budget; this model instead serves equipment with separate power. Fixed uplinks mean the purchase does not require a removable network card to provide the optical connections.

176 Gbps switching capacity accommodates traffic across the access and uplink interfaces, while 130.95 Mpps forwarding applies to 64-byte packets. Static IPv4 routing and RIP v2 handle routed connectivity; VRRP v2/v3 provides virtual gateway redundancy. Dynamic routing is limited to RIP v2. SG500X-48-K9 carries 256 MB of DRAM and 32 MB of flash for its embedded software and configuration. A 16384-entry MAC table supports address learning across connected networks. STP, RSTP and MSTP control Layer 2 forwarding paths, with 16 MSTP instances available for separate spanning-tree arrangements. LACP supports 32 aggregation groups with eight active ports per group. Browser administration uses HTTP/HTTPS, and Textview CLI supports full and menu-based operation. SNMP v1/v2c/v3 provides management-system integration. Hardware stacking groups eight members under a single logical system, rather than merely collecting independent devices in a dashboard.
Specify SG500X-48-K9 in new sealed or certified refurbished condition, with the required quantity and accessories identified on the purchase order. Certified refurbished units are inspected and bench-tested for power-on, POST, clean boot, rated-speed port links, optics bay recognition and fan status; firmware is verified and configuration is wiped to factory default. New units carry up to 3-year extended warranty, certified refurbished units carry up to 1-year warranty, and every condition includes 30-day returns with terms applying; Cisco warranty and service ended April 30, 2023. PO orders are accepted, government buyers have Net-30 terms, and enterprise or volume orders can specify regional stock and RMA requirements across the UK, EU, US and MEA, including advance replacement.

When expanding an existing stack, the 500X can share a stack with 500-family switches, but mixed-family connections use different link speeds from an all-500X arrangement. SFP-H10GB-CU1M supports a 1m copper connection. Specify the cable length and confirm the intended stacking mode before placing the purchase order.
When consolidating networks that currently rely on separate gateways, the switch supports routed interfaces on physical ports, aggregation groups, VLANs and loopbacks. Its IPv4 interface limit is 256. Count the required gateway interfaces and identify which networks remain on an external router before specifying the configuration on the purchase order.
When adding a staging unit for configuration rehearsals, dual firmware images allow separate images to reside on the switch. Editable text configurations support preparing settings before deployment. Include the required condition on the order, then specify the intended firmware image and configuration baseline before moving the unit into service.
Power delivery to connected endpoints
SG500X-48-K9 supplies no PoE to connected equipment. C1300-48P-4X provides the current migration option with powered access ports, retaining 48 Gigabit ports and four 10G SFP+ uplinks.
Current Cisco service eligibility
Cisco service for SG500X-48-K9 ended April 30, 2023. The replacement chain leads to C1300-48T-4X rather than the discontinued 550X and Business 350 intermediate families.
Fanless operation in occupied spaces
SG500X-48-K9 uses two fans and has a published acoustic level of 41.1 dB. A requirement for silent, fanless operation excludes this hardware configuration.

SG500X-48-K9 identifies a managed Gigabit switch with 48 access ports and four 10G SFP+ connections. SG500X identifies the Gigabit model group with 10G connections, and 48 identifies the access-port count. K9 remains part of the complete ordering identifier; this configuration has no powered access ports.
SG500X-48-K9 is managed through an HTTP/HTTPS web interface, Textview CLI using console or SSH/Telnet access, and SNMP v1/v2c/v3. Cisco OnPlus integration provides another monitoring path. Full and menu-based CLI modes support configuration, and stacked switches can be administered through a single IP address.
SG500X-48-K9 belongs to a retired family whose end-of-sale date was April 12, 2018, and whose Cisco support ended April 30, 2023. The 550X replacement family is also discontinued. Following the subsequent Business 350 migration leads to C1300-48T-4X for the corresponding non-PoE configuration.
ORM offers SG500X-48-K9 new sealed with up to 3-year extended warranty or certified refurbished with up to 1-year warranty. Both conditions include 30-day returns; terms apply. Cisco's original Limited Lifetime hardware warranty has ended with Cisco service on April 30, 2023. Refurbished units are inspected, bench-tested, firmware verified and factory-reset.
SG500X-48-K9 provides four fixed 10G SFP+ connections, including two that can also serve as stacking connections. Compatible optical choices include SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. Select the optical PID and allocate stacking connections before determining how many uplinks remain available.
A 500X hardware stack contains eight members and supports ring or chain arrangements with master and backup control. Compatible copper connections include SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M. Mixed stacks with 500-family switches use different connection speeds, so member compatibility and operating mode must be checked together.
SG500X-48-K9 supports static IPv4 and IPv6 routing, plus RIP v2 for dynamic routing. IPv4 static routing supports 2048 routes and 256 IP interfaces. VRRP v2/v3 provides virtual gateway redundancy. Routed interfaces can be configured on physical ports, aggregation groups, VLANs and loopbacks without implying broader enterprise routing protocols.
SG500X-48-K9 uses an internal AC supply accepting 100-240V AC at 47-63 Hz, with a published worst-case consumption of 60.3W. The supply powers the switch itself rather than connected endpoints. This configuration does not provide internal redundant power modules or a PoE budget for attached equipment.
The 48-port Gigabit SG500X-48-K9 is a 1U rack-mount switch measuring 440 mm wide, 44 mm high and 257 mm deep. Its weight is 4.01 kg, and cooling uses two fans. Operating temperature is 0°C to 40°C, so rack placement must accommodate ventilation and ambient temperature.
SG500X-48P-K9 adds PoE+ on 48 access ports with a shared 375W budget, whereas SG500X-48-K9 provides no endpoint power. Both configurations are discontinued. For matching existing hardware, the powered model serves endpoints requiring switch-delivered power, while the non-PoE model serves separately powered equipment.
SG500X-48-K9 provides 48 Gigabit access ports, while SG500X-24-K9 provides 24; both have four 10G SFP+ connections and no PoE. Both models are discontinued. Existing-hardware requirements favor the larger model for higher connection counts and the smaller model when only 24 access connections are required.
SG500X-48-K9 has passed its Cisco support end date, while C1300-48T-4X is the current endpoint of the replacement chain. The newer model retains 48 Gigabit ports and four 10G SFP+ uplinks. Existing retired-hardware matching favors the older unit; migration purchasing points to the current model.
