C9500X-28C8D-A is a managed Layer 3 core switch built for high-density 100G and 400G aggregation, with 28 fixed 40/100G QSFP28 ports and 8 fixed 40/100/200/400G QSFP-DD ports. Its uplinks are fixed front-panel interfaces rather than an empty modular bay, and the platform is Non-PoE in a Rack-Mount 1U chassis within the Cisco Catalyst 9500X series. The fiber-only layout suits buyers standardizing on QSFP optics for collapsed core, distribution aggregation, or high-capacity service insertion, while the fixed design keeps the port map consistent across every unit ordered under this part number. Buyers comparing licensing should note that C9500X-28C8D-E uses the same 28x100G plus 8x400G hardware layout but differs by shipping with Network Essentials instead of the Network Advantage software image. This SKU targets refreshes that need native 400G handoff without moving into a modular chassis.
12 Tbps switching capacity supports dense aggregation between campus core, distribution, and high-speed routing domains. 8 Bpps forwarding rate keeps the Q200 ASIC profile aligned with heavy Layer 3 traffic, multicast replication, and large routed fabrics. N/A PoE budget reflects a fiber-only Non-PoE design, so power planning centers on the chassis and redundant power supplies instead of endpoint delivery. BGP, EIGRP, HSRP, IS-IS, OSPF, PIM SM, PIM SSM, VXLAN, LISP, MPLS, and BGP-EVPN support the Network Advantage feature set for advanced enterprise routing and segmentation. C9500X-28C8D-A carries 32 GB DRAM and 32 GB flash, while 256000 MAC address scale and 4094 VLAN IDs support large Layer 2 and Layer 3 domains without shifting platform families. 90-264V AC / -40 to -72V DC input options and 1182W power consumption shape rack-level electrical planning for redundant core deployments. Fiber media support keeps production interfaces on pluggable optics or DAC paths, which is useful when standardizing 100G breakout and 400G interconnect designs.
In enterprise core and distribution tiers, this switch connects 100G aggregation peers, 400G spine or core links, routers, firewalls, service nodes, and high-speed server access platforms. StackWise Virtual forms a two-unit logical system for resilient multichassis designs, and the 1U rack footprint keeps paired deployments compact in standard cabinets where port density and airflow planning matter. Matching license level, model, software version, and SDM template across paired units keeps high-availability prerequisites predictable during implementation. ORM Systems offers C9500X-28C8D-A new and certified refurbished, with refurb validation focused on QSFP port recognition, power-supply health, fan operation, and orderable-part accuracy. Request pricing with quantity, optics, airflow, and license-term requirements; ORM Systems supports enterprise and volume buyers building staged core refreshes, sparing pools, or standardized high-speed switch inventories across multiple sites. Larger orders align chassis availability, optics sourcing, and lifecycle planning under one procurement motion.

C9500X-28C8D-A occupies the campus core and terminates 40G or 100G routed links from distribution blocks on 28 QSFP28 ports. Eight QSFP-DD ports carry 100G, 200G, or 400G connections toward peer cores, shared services, or upstream routing. Engineers apply Network Advantage routing, VRF segmentation, QoS, multicast, telemetry, and MACsec policies through Cisco IOS XE, then align optics and MTU settings across every handoff. The 1RU platform consolidates high-speed distribution traffic into a compact routed core while preserving clear policy and failure boundaries.
C9500X-28C8D-A sits at the aggregation tier between access distribution systems and centralized network services. Its QSFP28 interfaces collect 40G and 100G trunks or routed links, while QSFP-DD interfaces provide higher-capacity paths toward the core or service edge. Engineers use EtherChannel, BGP, OSPF, IS-IS, VLANs, and VRFs to separate failure domains and control route exchange. Supported breakout modes adapt selected ports to lower-speed handoffs where the cabling plan requires them. The resulting topology concentrates mixed high-speed connections without introducing a modular chassis.
Two C9500X-28C8D-A switches form a StackWise Virtual core pair with designated high-speed links and a separate dual-active detection path. Both chassis forward traffic while the active control plane manages Layer 2 and Layer 3 protocols across the virtual system. Engineers dual-home downstream distribution switches through multichassis EtherChannel, split upstream paths across both members, and match IOS XE releases, licenses, optics, airflow, and power feeds. Stateful Switchover preserves control-plane continuity during a member failure, leaving the network with redundant forwarding and one operational management domain.

C9500X-28C8D-A is a fixed 1RU Cisco Catalyst 9500X core and aggregation switch supplied with the Network Advantage perpetual license tier. Its front panel provides 28 QSFP28 ports for 40G or 100G links and eight QSFP-DD ports for 40G, 100G, 200G, or 400G links. Cisco positions the platform for high-density enterprise campus core and distribution designs.
The C9500X-28C8D-A identifier specifies a Catalyst 9500X platform with 28 native QSFP28 positions, eight native QSFP-DD positions, and the Network Advantage license tier. The suffix distinguishes it from C9500X-28C8D-E, which uses the same hardware port layout with Network Essentials. The SKU identifies the licensed base configuration, while optics, subscription term, power options, and accessories require separate confirmation.
C9500X-28C8D-A is a managed Layer 2 and Layer 3 Ethernet switch, not a router appliance, modular chassis, access point, or optical transceiver. It runs Cisco IOS XE and uses a fixed-port 1RU chassis based on the Cisco Silicon One Q200 ASIC. The unit targets fiber-heavy core and aggregation roles where high-speed routed and switched interfaces are required.
C9500X-28C8D-A sits at the high-density end of Cisco's fixed Catalyst 9500 enterprise core and aggregation portfolio. It provides native 400G QSFP-DD connectivity above the 100G-focused C9500 high-performance models, while retaining the fixed 1RU form factor. Within the Catalyst 9500X pair, it emphasizes 100G and 400G density, whereas C9500X-60L4D-A emphasizes 10G, 25G, and 50G SFP56 density.
C9500X-28C8D-A provides 36 native front-panel data ports: 28 QSFP28 positions supporting 40G or 100G modules and eight QSFP-DD positions supporting 40G, 100G, 200G, or 400G modules. Cisco also supports 10G through a QSA on these port groups. Breakout support applies to odd-numbered QSFP28 ports and all QSFP-DD ports, subject to IOS XE and cable compatibility.
C9500X-28C8D-A is specified by Cisco with up to 12 Tbps of platform switching capacity and an 8 Bpps forwarding rate. Its Cisco Silicon One Q200 ASIC is described as a 12.8 Tbps full-duplex architecture, so those figures should not be treated as interchangeable test conditions. Actual traffic performance depends on packet size, port mode, breakout configuration, software release, and enabled services.
C9500X-28C8D-A does not provide PoE, PoE+, or UPOE output. Its QSFP28 and QSFP-DD interfaces are high-speed optical or direct-attach network ports rather than powered copper access ports. Devices such as wireless access points, phones, and cameras require separate PoE access switches or injectors. The two power-supply slots power the chassis and do not create an endpoint PoE budget.
C9500X-28C8D-A supports enterprise Layer 2 switching and Layer 3 routing through Cisco IOS XE, including VLANs, EtherChannel, spanning tree, IPv4 and IPv6 routing, BGP, OSPF, IS-IS, multicast, QoS, ACLs, and segmentation features according to the licensed release. Network Advantage adds the higher software tier, but exact feature availability remains tied to the installed IOS XE version and subscription entitlement.
C9500X-28C8D-A supports local administration through the Cisco IOS XE CLI, console interfaces, SSH, SNMP, NETCONF, RESTCONF, and model-driven telemetry. Cisco Catalyst Center provides centralized discovery, automation, assurance, and lifecycle workflows with the appropriate subscription. Cisco also lists Meraki cloud monitoring as an operational option, although feature support varies by platform and software release and should be checked before design approval.
C9500X-28C8D-A supports Cisco StackWise Virtual rather than physical StackWise stacking cables used by many access switches. Two compatible switches form one logical control and management system across designated StackWise Virtual Links, with Stateful Switchover and multichassis EtherChannel designs available under supported IOS XE releases. Both members require compatible hardware, matching software, licensing, optics, and a planned dual-active detection method.
C9500X-28C8D-A is used as a high-capacity campus core, distribution aggregation point, or routed handoff platform. Its 28 QSFP28 ports aggregate 40G and 100G links from distribution blocks, while eight QSFP-DD ports provide 100G, 200G, or 400G paths toward peer cores, services, or upstream routing. Network Advantage supports designs requiring advanced routing, segmentation, telemetry, and high-availability functions.
C9500X-28C8D-A suits large or bandwidth-intensive enterprise networks that already require multiple 40G, 100G, 200G, or 400G fiber links. A smaller environment with mostly 1G, 10G, or 25G endpoints usually gains better port economics from another Catalyst model. The switch fits designs where a compact 1RU core must consolidate many high-speed distribution or aggregation connections without a modular chassis.
C9500X-28C8D-A fits east-west and north-south traffic aggregation for high-density campus backbones, large routed domains, service blocks, and high-speed connections to compute or network services. The 8 Bpps forwarding rate and 100G/400G interface mix suit traffic consolidation rather than direct user access. Workload planning should include route scale, buffer profile, oversubscription, optics, redundancy, and IOS XE feature requirements.
C9500X-28C8D-A works in a redundant fixed-core design when two compatible units are configured with StackWise Virtual, redundant power, separate upstream paths, and multichassis EtherChannel where appropriate. The active and standby control roles use Stateful Switchover while both chassis forward traffic. A complete design also assigns resilient StackWise Virtual Links, dual-active detection, matched IOS XE releases, and tested failure procedures.
C9500X-28C8D-A accepts Cisco-supported QSFP28 modules on its 28 40G/100G ports and QSFP-DD modules on its eight 40G/100G/200G/400G ports. Supported breakout cables convert eligible 100G ports to four 25G or 10G lanes, while QSA adapters enable selected 10G SFP+ use. Exact optic, DAC, AOC, wavelength, reach, and breakout support must match Cisco's current transceiver compatibility matrix.
C9500X-28C8D-A integrates with Cisco Catalyst 9300 and 9400 distribution or access platforms, Catalyst 9500 peers, and Catalyst 9600 core systems through standards-based Ethernet links. Common integrations use 802.1Q trunks, LACP EtherChannel, OSPF, BGP, IS-IS, VRFs, IPv4, IPv6, multicast, and MACsec. Link speed, optics, MTU, routing policy, and software interoperability require validation on both endpoints.
C9500X-28C8D-A runs Cisco IOS XE and integrates with Cisco Catalyst Center for inventory, automation, software lifecycle, assurance, and policy workflows under the correct subscription. Cisco Smart Software Manager handles license reporting through a Smart Account. Standards-based systems also integrate through SNMP, NETCONF, RESTCONF, YANG models, syslog, and streaming telemetry. Supported functions depend on the IOS XE release and controller compatibility matrix.
C9500X-28C8D-A occupies 1RU and ships within Cisco's C9500X mechanical ecosystem, including 19-inch or 23-inch rack accessory kits and optional four-point mounting hardware. The chassis has two power-supply slots and supports matched Cisco C9500X AC or DC power options listed for the platform. Airflow direction, fan type, input power, circuit capacity, cords, and redundant-feed design must align across the ordered configuration.
C9500X-28C8D-A and C9500X-28C8D-E use the same 28-port QSFP28 plus eight-port QSFP-DD hardware layout. The difference is the embedded network license tier: the -A SKU carries Network Advantage, while the -E SKU carries Network Essentials. C9500X-28C8D-A fits designs needing the higher routing and segmentation feature tier; the -E model suits requirements covered by Essentials.
C9500X-28C8D-A prioritizes 100G and 400G density with 28 QSFP28 and eight QSFP-DD ports. C9500X-60L4D-A instead provides 60 SFP56 ports for 10G, 25G, or 50G and four QSFP-DD ports up to 400G. Both use the Catalyst 9500X architecture and Network Advantage tier, but C9500X-60L4D-A better fits dense lower-speed aggregation while C9500X-28C8D-A fits a faster core.
C9500X-28C8D-A adds eight native QSFP-DD interfaces up to 400G alongside 28 QSFP28 ports, while C9500-32C-A supplies 32 QSFP28 ports focused on 40G and 100G. The 9500X model uses Cisco Silicon One Q200 and offers higher forwarding scale; C9500-32C-A uses UADP 3.0. The older 32-port model remains relevant where 400G is unnecessary and a 100G-focused design is preferred.
C9500X-28C8D-A is not a direct port-for-port replacement for C9500-48Y4C-A. The C9500-48Y4C-A provides 48 SFP28 ports for 1G, 10G, or 25G access to services plus four 40G/100G uplinks. C9500X-28C8D-A starts at QSFP-class 40G/100G density and adds 400G. Migration requires a new optics, breakout, cabling, port-density, power, and software design rather than a chassis swap.
C9500X-28C8D-A may be sourced in new or refurbished condition through ORM Systems, subject to current channel and tested-stock availability. A quotation should identify condition, serial status, included power supplies and fans, airflow direction, rack kit, software entitlement, subscription requirements, warranty term, and optics. Buyers should not assume that a bare hardware listing includes transceivers, power cords, Smart Net, or a subscription license.
C9500X-28C8D-A pricing is quotation based because condition, quantity, license term, power configuration, support, optics, and destination materially affect the total. The base SKU includes the Network Advantage tier, but Cisco requires a matching Catalyst Software Subscription or Cisco DNA subscription on new orders. ORM Systems can price the chassis alone or build a bill of materials that separates required and optional components.
C9500X-28C8D-A is not listed in Cisco's current Catalyst 9500 hardware end-of-sale notices reviewed for this content. Cisco documentation continues to list the model in the active Catalyst 9500X portfolio and ordering tables. Software releases have separate lifecycle notices, so production status should not be confused with an individual IOS XE train reaching end of support. Current status should be reconfirmed at quotation time.
C9500X-28C8D-A lead time depends on condition, quantity, regional stock, license selection, airflow direction, power supplies, optics, rack accessories, and delivery destination. A complete bill of materials generally receives a more reliable estimate than a chassis-only request. ORM Systems should confirm allocation and dispatch timing in the quotation, especially when multiple matched units are required for StackWise Virtual or a staged core migration.
Bulk quotation pricing is available from ORM Systems for multi-unit C9500X-28C8D-A requirements, although the discount depends on quantity, condition, configuration, and sourcing. Project buyers should specify switch count, license tier and term, power redundancy, airflow, optics, rack kits, support, delivery sites, and required dates. A standardized bill of materials helps avoid price comparisons between incomplete chassis listings and deployment-ready configurations.
Warranty coverage for C9500X-28C8D-A depends on the quoted condition and support package. ORM Systems states that brand-new and factory-refurbished goods carry the applicable manufacturer's warranty, while used goods carry a 30-day seller warranty under its published terms. The order should record the exact warranty duration, replacement process, exclusions, serial eligibility, and whether Cisco support or a separate reseller warranty applies.
Refurbished C9500X-28C8D-A stock should be validated for successful boot, Cisco IOS XE operation, fan and power-supply health, console and management access, interface recognition, link stability, alarms, and physical condition before dispatch. Testing should also verify the ordered airflow direction and included components. The quotation should state the refurbishment grade, test coverage, software image, serial status, warranty, and any excluded optics or accessories.
C9500X-28C8D-A supports standards-based Ethernet and is listed by Cisco against relevant safety requirements including EN, UL, CAN/CSA, IEC, and AS/NZS 62368-1. The platform also supports technologies such as IEEE 802.1Q, link aggregation, IPv4, IPv6, and 256-bit MACsec under supported software. Procurement teams should request the exact regional declarations and regulatory documents required for the destination country.
Initial deployment starts by installing matched power supplies and fans, racking the 1RU chassis, connecting console or management access, and loading a supported Cisco IOS XE release. Engineers then assign management addressing, credentials, AAA, NTP, logging, routing, VLANs, interface speeds, and security policy. Before production cutover, the configuration should validate optics, breakout modes, MTU, licensing, redundancy, telemetry, and saved startup configuration.
C9500X-28C8D-A includes the perpetual Network Advantage network stack tier and runs Cisco IOS XE. Cisco's current ordering model also requires a matching Catalyst Software Subscription or Cisco DNA Advantage subscription for a 3, 5, or 7-year term on new purchases. License administration uses a Cisco Smart Account and Smart Software Manager. Exact features remain dependent on entitlement and the selected IOS XE release.
A deployable C9500X-28C8D-A configuration needs compatible power supplies, fan airflow, power cords, rack hardware, supported QSFP28 or QSFP-DD optics or cables, fiber plant, and a management connection. StackWise Virtual adds peer links and dual-active detection planning. Engineers also need a supported IOS XE image, Smart Account, matching subscription, addressing plan, console access, configuration backup, and validated interoperability with every connected platform.
UK buyers can request C9500X-28C8D-A pricing from ORM Systems through ormsystems.com. The request should include quantity, new or refurbished preference, Network Advantage subscription term, AC or DC power, airflow direction, optics, rack accessories, warranty, support, and delivery postcode. A written quote should identify VAT treatment, availability, lead time, included components, and whether the proposed configuration is Cisco-original and deployment ready.
ORM Systems supports international delivery for C9500X-28C8D-A and publishes global shipping options, including Delivered Duty Paid service for eligible orders. Shipping terms depend on destination, shipment value, unit count, weight, insurance, import rules, and local service coverage. The quotation should confirm Incoterms, duties and taxes, carrier, transit estimate, packaging, export restrictions, warranty return route, and delivery responsibility before the order is placed.
