C9500X-28C8D-E is a managed Layer 3 Catalyst 9500X core switch built for high-density fiber aggregation in enterprise campus networks. The fixed hardware provides 28 QSFP28 ports for 40G or 100G links and 8 QSFP-DD ports for 40G, 100G, 200G, or 400G uplinks, with no empty modular bay to populate. Non-PoE operation keeps the platform focused on optical core, distribution, and aggregation traffic rather than powered endpoint access. Its front panel suits dense fiber handoff designs where distribution switches, service edges, or high-speed access blocks require native 100G paths and consolidated 400G uplink capacity. The 1U rack-mount chassis belongs to the Cisco Catalyst 9500X Series and uses the Network Essentials software image. C9500X-28C8D-A is the closest confirmed sibling, with the same 28x100G plus 8x400G port layout but a Network Advantage license instead of Network Essentials.
12 Tbps switching capacity delivers the fabric scale required for multiple 100G distribution links and fixed 400G uplink paths. 8 Bpps forwarding rate supports high-volume routed and switched traffic across the Catalyst 9500X forwarding architecture. Non-PoE design removes endpoint power allocation from the chassis plan, while routed access features in Network Essentials include RIP, EIGRP Stub, and OSPF up to 1000 routes, with PBR and PIM Stub Multicast also documented for the tier. 128000 default MAC addresses and 4094 VLAN IDs support large Layer 2 domains where the switch sits above dense access or distribution blocks. C9500X-28C8D-E includes 32 GB DRAM and 32 GB flash, alongside 80 MB of dedicated low-latency buffer and up to 8 GB of HBM buffer for deep packet buffering. Minimum IOS XE Software Release 17.7.1 anchors software planning. Cisco IOS XE management covers CLI, WebUI, NETCONF, RESTCONF, gRPC, gNMI/gNOI, YANG models, PnP, ZTP, telemetry, SPAN, and RSPAN.
Core and distribution deployments place C9500X-28C8D-E between downstream Catalyst aggregation switches, high-speed server access blocks, WAN edge devices, and upstream optical transport or data center handoff links. QSFP28 and QSFP-DD transceiver selection should match Cisco compatibility guidance, while StackWise Virtual is not included with Network Essentials, so paired-core designs use the licensed feature set actually ordered. Rack space remains 1U, with dual power-supply bays, optional redundant AC or DC supplies, and selectable Catalyst 9500X airflow direction supporting dense network rooms. ORM Systems supplies this switch new and certified refurbished. Refurbished units are checked for boot state, port recognition, fan health, power-supply status, and chassis condition before dispatch. Enterprise buyers receive a clear bill of materials for optics, power, and support alongside the chassis.

C9500X-28C8D-E sits at the campus core and aggregates high-speed fiber links from distribution blocks over 28 QSFP28 ports operating at 40G or 100G. Engineers reserve the 8 QSFP-DD ports for 100G, 200G, or 400G uplinks toward peer core switches, data center handoffs, or upstream network services. Cisco IOS XE carries routed core policy, telemetry, and operational controls under the Network Essentials license design. Power and fan redundancy support planned maintenance in core racks. The network gains a compact 1RU core switch with predictable high-speed aggregation and fewer uplink bottlenecks.
The switch occupies a distribution layer and terminates high-speed fiber from access aggregation, building distribution, or server access blocks. C9500X-28C8D-E maps 28 QSFP28 interfaces to 40G or 100G downlinks and uses the QSFP-DD ports for consolidated 400G paths toward the core. Engineers configure routed links, EtherChannel, telemetry, and management access through Cisco IOS XE before moving traffic. The 1RU form factor keeps the handoff compact in distribution racks. The design reduces separate aggregation devices and gives the distribution layer a clearer path into the core.
Two Catalyst 9500X switches form a StackWise Virtual core pair on supported IOS XE releases, with multichassis EtherChannel links carrying traffic from downstream distribution switches. C9500X-28C8D-E contributes dense QSFP28 and QSFP-DD fiber capacity to the pair while the Network Essentials ordering level anchors the base software entitlement. Engineers align software releases, optics, power redundancy, and airflow before enabling the virtual system. The 1RU chassis keeps paired deployments practical in constrained core cabinets. The network gains dual-switch resiliency with simplified core operations and controlled failure domains.

Cisco C9500X-28C8D-E is a Catalyst 9500X fixed core switch for high-density campus core and distribution designs. It provides 28 QSFP28 ports for 100G or 40G connectivity and 8 QSFP-DD ports for 400G, 200G, 100G, or 40G connectivity. The SKU ships with the Network Essentials license level.
C9500X identifies the Cisco Catalyst 9500X platform, 28C8D identifies the 28 QSFP28 plus 8 QSFP-DD port layout, and the E suffix identifies Network Essentials. For ordering, C9500X-28C8D-E separates this SKU from the C9500X-28C8D-A version, which uses the Network Advantage license level for broader software entitlement.
C9500X-28C8D-E is a fixed enterprise Ethernet switch, not a line card, router, or removable network module. It is designed for core and distribution switching roles where dense 100G and 400G fiber ports are required in a 1RU Catalyst 9500X chassis with redundant power-supply capability and Cisco IOS XE software.
C9500X-28C8D-E sits in the Cisco Catalyst 9500X family, above lower-speed Catalyst 9500 high-performance models such as C9500-48Y4C-E and C9500-32C-E. It targets campus core, distribution, and aggregation designs that need 100G QSFP28 density plus 400G QSFP-DD uplinks on the Cisco Silicon One Q200 ASIC platform within Cisco campus switching.
C9500X-28C8D-E has 36 front-panel high-speed Ethernet ports. The port layout is 28 QSFP28 ports for 40G or 100G operation and 8 QSFP-DD ports for 40G, 100G, 200G, or 400G operation, depending on optics, cabling, configured interface mode, and optical module support.
Cisco lists the C9500X-28C8D platform with up to 12 Tbps switching capacity and an 8 Bpps forwarding rate. The Catalyst 9500X family uses Cisco Silicon One Q200 silicon, which is built for high-speed core and edge switching with full routing and switching functions on the platform.
C9500X-28C8D-E does not provide PoE because it is a fiber core and distribution switch with QSFP28 and QSFP-DD ports. It connects aggregation, distribution, data center edge, or high-speed access blocks rather than powering phones, cameras, or wireless access points directly over copper Ethernet. Power planning focuses on chassis supplies, not endpoint budgets.
C9500X-28C8D-E operates as a managed Catalyst switch for Layer 2 switching and Layer 3 routing designs under Cisco IOS XE. The platform supports scalable routing and switching tables, IPv4 and IPv6 routing, multicast features, and segmentation features, with entitlement depending on the installed Network Essentials and DNA licensing.
C9500X-28C8D-E is managed through Cisco IOS XE using CLI, model-driven telemetry, programmable interfaces such as NETCONF and RESTCONF, and Cisco Catalyst Center workflows where licensed and deployed. It also fits Cisco cloud monitoring options for Catalyst environments that use supported IOS XE releases and Cisco management integrations.
C9500X-28C8D-E is not an access-layer stack member in the Catalyst 9200 or 9300 style. The Catalyst 9500X platform supports Cisco StackWise Virtual for two-switch system virtualization on supported IOS XE releases, allowing paired core or distribution switches to operate with a shared control-plane design and multichassis EtherChannel links.
C9500X-28C8D-E is used for high-speed campus core, distribution aggregation, and fiber handoff designs. Network teams deploy it where many 40G or 100G downstream links need to aggregate into 100G, 200G, or 400G uplinks without moving to a modular chassis architecture. The fixed 1RU format simplifies rack planning.
C9500X-28C8D-E fits large campus networks, collapsed core designs, and aggregation layers that already use high-speed optical links. Its 28 QSFP28 and 8 QSFP-DD ports suit environments where multiple distribution, server access, or WAN edge blocks require dense fiber interconnection and predictable high-throughput switching across a compact core footprint.
C9500X-28C8D-E suits east-west aggregation, routed campus core traffic, high-bandwidth inter-building links, and 100G distribution uplinks. It is also appropriate for designs using 400G QSFP-DD links to reduce uplink count while preserving high-speed fiber capacity between core, distribution, and edge switching layers. Telemetry-heavy operations also fit the IOS XE platform.
C9500X-28C8D-E works in collapsed core deployments where the same switch pair handles core routing and distribution aggregation. The 28 QSFP28 ports provide dense 100G or 40G handoffs, while the 8 QSFP-DD ports support higher-speed uplinks for interconnect, aggregation, or upstream network services. StackWise Virtual designs should use supported IOS XE releases.
C9500X-28C8D-E runs Cisco IOS XE, with Cisco listing IOS XE Software Release 17.7.1 as the minimum software requirement for the C9500X-28C8D model. This makes the SKU part of the programmable Catalyst switching ecosystem that supports telemetry, automation interfaces, patching workflows, and operational tooling around IOS XE.
C9500X-28C8D-E uses QSFP28 optics or cables on its 28 high-speed ports and QSFP-DD optics or cables on its 8 highest-speed ports. Cisco directs buyers to its Transceiver Module Group compatibility resources for the latest supported optics, so exact modules should be checked against the intended IOS XE release.
C9500X-28C8D-E fits Cisco Catalyst Center environments because it runs Cisco IOS XE and belongs to the Catalyst 9500 switching family. Network teams use Catalyst Center for inventory, monitoring, configuration workflows, assurance, and automation when the software release, licensing, and campus architecture align with Cisco’s supported feature matrix.
C9500X-28C8D-E integrates through Ethernet optical standards, Cisco IOS XE management protocols, routing protocols, and security capabilities such as MACsec-256 and WAN MACsec where supported. Designs commonly validate IPv4, IPv6, multicast, routed uplinks, EtherChannel, telemetry, and optical compatibility before placing the switch into a production core.
C9500X-28C8D-E and C9500X-28C8D-A use the same 28x100G QSFP28 plus 8x400G QSFP-DD hardware layout. The main ordering difference is licensing: C9500X-28C8D-E is listed with Network Essentials, while C9500X-28C8D-A is listed with Network Advantage for buyers that require the higher license tier. The physical deployment requirements remain identical.
C9500X-28C8D-E provides 28 QSFP28 ports and 8 QSFP-DD ports, while C9500X-60L4D-A provides 60 SFP56 ports and 4 QSFP-DD ports. The 28C8D model better fits dense 100G and 400G aggregation, while the 60L4D model better fits larger counts of 10G, 25G, or 50G fiber links overall.
C9500X-28C8D-E is a Catalyst 9500X model with 28 QSFP28 ports, 8 QSFP-DD ports, and Cisco Silicon One Q200 architecture. C9500-32C-E is a Catalyst 9500 high-performance model with 32 QSFP28 ports for 40G or 100G. Buyers choose between 400G uplink density and simpler 32-port 100G density.
C9500X-28C8D-E targets 100G and 400G fiber aggregation with QSFP28 and QSFP-DD ports. C9500-48Y4C-E targets 1G, 10G, and 25G distribution links using 48 SFP28 ports plus 4 QSFP uplinks. The better fit depends on whether the design needs high port count at 25G or fewer, faster core links.
C9500X-28C8D-E is typically sourced by enterprise resellers in new, refurbished, or excess-stock condition depending on market availability. Buyers should match condition to budget, lead-time, warranty, and support requirements, especially when the switch is being deployed into a core network role with strict maintenance expectations and spare planning.
C9500X-28C8D-E price depends on condition, regional supply, included power supplies, fan airflow direction, optics, software term, warranty length, and order quantity. The Network Essentials hardware PID is only one part of the total purchase, because optics, power cords, licenses, and support coverage often change the final project cost.
C9500X-28C8D-E appears in current Cisco Catalyst 9500 ordering and software documentation used for this content in validated Cisco sources. Buyers should still verify Cisco lifecycle notices before purchase, because end-of-sale and last-support dates are controlled by Cisco and affect long-term maintenance planning for core switching deployments.
C9500X-28C8D-E lead time depends on live stock, requested condition, accessory bundle, destination, and whether optics or license terms are ordered with the switch. Refurbished or channel-stock units often move differently from factory-new supply, so procurement teams should request a dated quote before scheduling deployment work.
Bulk pricing for C9500X-28C8D-E is usually evaluated by quantity, condition mix, warranty term, and accessory requirements. Multi-site refreshes, paired core deployments, and standardized spares planning often justify volume pricing because the order may include multiple switches, matching airflow, redundant power supplies, optics, and support coverage.
ORM Systems refurbished supply for C9500X-28C8D-E should include functional checks appropriate for a managed fiber switch before dispatch. Testing normally focuses on boot health, port recognition, power-supply status, fan status, software state, serial identity, and visible hardware condition so buyers receive a unit suitable for installation planning.
C9500X-28C8D-E warranty terms from ORM Systems depend on condition, quote details, and selected coverage. Buyers should confirm whether the order includes reseller warranty, extended hardware cover, Cisco support eligibility, or separate Smart Net style support, because a core switch usually requires clear replacement and escalation expectations.
C9500X-28C8D-E should be assessed against Cisco’s official safety, electromagnetic, environmental, and regulatory documentation for the Catalyst 9500X platform. Procurement teams often request confirmation for regional power cords, AC input range, rack installation requirements, RoHS status, and country-specific compliance before approving shipment into controlled infrastructure environments.
C9500X-28C8D-E is first configured through Cisco IOS XE using console access, management Ethernet, or approved automation workflows. Engineers normally confirm software release, licensing state, management IP addressing, AAA, routing templates, interface speed settings, optics recognition, logging, time synchronization, and redundant core design settings before production traffic is migrated.
C9500X-28C8D-E is listed with Network Essentials as the default license level, and Cisco DNA term licenses may be selected during ordering. The exact entitlement should match the intended feature set, management platform, and deployment role, because advanced segmentation, automation, and assurance workflows depend on Cisco licensing rules.
C9500X-28C8D-E deployments should plan for compatible QSFP28 and QSFP-DD optics or cables, power cords with the correct regional connector, rack rails, airflow direction, redundant power supplies, management cabling, console access, and approved IOS XE software. Fiber patching and upstream port capability should be validated before installation.
Buyers can purchase C9500X-28C8D-E in the UK through ORM Systems as a Cisco enterprise networking reseller. The quote should specify condition, warranty, included power supplies, airflow, software and license terms, optics, delivery location, and any bulk project requirements so the supplied switch matches the intended core design.
ORM Systems can quote C9500X-28C8D-E for international buyers subject to stock, export rules, courier availability, destination restrictions, and requested condition. International orders should confirm power cords, warranty handling, customs documentation, delivery terms, whether optics or accessories ship with the same consignment, and dispatch planning.
