C9500-24Y4C-E is a high-performance managed Layer 3 switch built around 25G fiber aggregation rather than copper endpoint access. It provides 24 1/10/25G SFP28 ports with four fixed 40/100G QSFP28 uplinks, no PoE, and a rack-mount chassis in the Cisco Catalyst 9500 Series. The fixed uplink design removes the need to select a separate network module, so buyers specify optics, power supplies, and software entitlement around the chassis instead of an expansion bay. Network Essentials positions the platform for routed access, distribution, and core roles under Cisco IOS XE. Its all-fiber front panel suits aggregation designs that collect 10G or 25G handoffs and forward traffic into 40G or 100G backbone links. C9500-24Y4C-A is the closest sibling on the same hardware, with Network Advantage replacing this SKU's Network Essentials license.
2 Tbps switching capacity supports dense aggregation between access blocks, services devices, and upstream core links without moving to a modular chassis. 1 Bpps forwarding rate gives the platform packet-processing headroom for concentrated campus traffic, routed uplinks, and high-speed fiber handoffs. 435W power consumption gives facilities teams a conservative planning value when the switch is configured with supported power supply options. RIP, EIGRP Stub, OSPF up to 1000 routes, PBR, PIM Stub Multicast up to 1000 routes, VRRP, QoS, SSO, NETCONF, RESTCONF, gRPC, gNMI/gNOI, YANG, PnP agent, ZTP/Open PnP, and Guest Shell are documented in the Network Essentials feature set. CLI and WebUI management keep base administration local to the Network Essentials package, while Catalyst software or Cisco DNA subscriptions add broader operations workflows when ordered. C9500-24Y4C-E carries 16 GB DRAM and 16 GB flash for Cisco IOS XE operation, software storage, and management workflows. Its 82,000-entry MAC scale and 9,216-byte jumbo frame support align the switch with large VLAN domains, routed distribution blocks, and fiber-heavy enterprise aggregation.
C9500-24Y4C-E fits enterprise core and distribution tiers, connecting Catalyst access switches, server adapters, firewalls, load balancers, and other aggregation endpoints through supported SFP28 and QSFP28 optics or direct-attach cabling. Stacking is not part of the Network Essentials tier, so deployments use standalone switches in paired routing or link-aggregation designs instead of a switch stack. A single rack unit keeps the aggregation node compact while leaving space for fiber management, redundant power feeds, and adjacent service appliances. ORM Systems supplies this switch new and certified refurbished, with refurbished units checked for boot status, management access, optical port function, power module health, and fan operation before dispatch. Request a formal quote with condition, quantity, optics, power supply preference, and delivery location. Enterprise and volume buyers receive configuration-aware pricing for refresh projects, spares holdings, multi-site aggregation rollouts, and spare-unit planning.
C9500-24Y4C-E price is $8,348.00, a 68.2% saving from the Cisco list price of $26,251.00. C9500-24Y4C-E is in stock and available for next-day dispatch. (terms applied)

C9500-24Y4C-E sits at the campus core and terminates routed uplinks from distribution blocks on 24 1/10/25G SFP28 interfaces. Four fixed 40/100G QSFP28 ports carry northbound or cross-core connections into higher-capacity aggregation paths. Engineers place Layer 3 boundaries, route summarization, access control, QoS, and high-availability policies at this tier under the Network Essentials image. Paired Catalyst 9500 switches use StackWise Virtual when the design calls for a single logical control point. The result is a fixed-core layer with predictable 25G aggregation and 100G handoff capacity.
The switch occupies a distribution layer above Catalyst access blocks and collects fiber uplinks from wiring closets on 1G, 10G, or 25G SFP28 ports. Network teams map each closet or access stack to routed links, trunks, or port channels, then reserve the four QSFP28 uplinks for 40G or 100G paths toward the core. C9500-24Y4C-E keeps endpoint switching below the distribution layer while concentrating policy and route control in one fixed 1U platform. The result is clearer access-to-core traffic flow and fewer bandwidth pinch points at distribution.
C9500-24Y4C-E sits in a server access or services aggregation row where 10G and 25G SFP28 connections land from compute, appliance, firewall, or load-balancing devices. Engineers group links with EtherChannel, define routed handoffs or VLAN trunks, and use the 40/100G QSFP28 ports for upstream fabric or core connectivity. The Network Essentials bundle supports the base switching and routing role without turning the platform into a PoE access switch. The result is a compact aggregation point for high-speed service blocks with controlled uplink oversubscription.

C9500-24Y4C-E is a Cisco Catalyst 9500 Series high-performance Layer 3 switch for fixed core, distribution, and aggregation roles. It provides 24 SFP28 ports supporting 1G, 10G, or 25G Ethernet and four fixed QSFP28 uplink ports supporting 40G or 100G Ethernet. The -E bundle includes the Network Essentials license tier for Cisco IOS XE deployments.
The C9500 portion identifies the Cisco Catalyst 9500 Series fixed enterprise switching platform. The 24Y4C portion identifies 24 SFP28 downlink ports plus four QSFP28 uplink ports on the high-performance 25G model. The final E identifies the Network Essentials bundle, while the adjacent C9500-24Y4C-A uses the Network Advantage license tier.
C9500-24Y4C-E is a fixed-configuration managed Layer 3 switch, not a router module or transceiver. It is a complete 1U Cisco Catalyst chassis with SFP28 access or aggregation ports, QSFP28 uplink ports, field-replaceable power supplies, and Cisco IOS XE software. Optics, power redundancy choices, and software subscription items are ordered around the switch.
C9500-24Y4C-E sits in the Cisco Catalyst 9500 Series, Cisco's fixed enterprise core and aggregation switching family. It belongs to the high-performance 25G models rather than the older 10G C9500-16X or C9500-40X platforms. It suits networks that need 25G fiber handoffs and 40G or 100G aggregation without moving to a modular chassis.
C9500-24Y4C-E has 24 SFP28 ports that support 1/10/25-Gigabit Ethernet connectivity and four fixed QSFP28 uplink ports that support 40/100-Gigabit Ethernet connectivity. The 24 SFP28 ports handle downlinks, server access, or distribution handoffs, while the four QSFP28 ports provide high-speed uplinks toward core, aggregation, or data center fabrics.
C9500-24Y4C-E is listed by Cisco with up to 2.0 Tbps switching capacity and up to 1 Bpps forwarding rate. Those figures position it for dense routed aggregation, high-speed campus core links, and 25G server-facing designs. Actual usable design headroom depends on traffic profile, optical choices, software release, templates, and enabled features.
C9500-24Y4C-E does not provide PoE because its front-panel interfaces are SFP28 and QSFP28 fiber or DAC ports rather than copper access ports. It is designed for high-speed optical or twinax switching, not direct powering of phones, cameras, or access points. PoE endpoint access normally sits on Catalyst 9200, 9300, or similar copper access switches.
C9500-24Y4C-E is a managed Layer 3 switch running Cisco IOS XE with the Network Essentials bundle. It supports campus switching roles that use VLANs, trunks, routed interfaces, ACLs, QoS, and routing according to the licensed feature set and software release. The platform is commonly placed above access switches where routed aggregation and high-speed uplinks are required.
C9500-24Y4C-E is managed through Cisco IOS XE using CLI, Web UI, automation interfaces, and Cisco Catalyst Center workflows where deployed. Cisco also describes an operational choice of Cisco Catalyst Center or Meraki cloud monitoring for Catalyst 9500 Series switches. Existing monitoring platforms integrate through standard enterprise network management methods such as SNMP, syslog, and telemetry.
C9500-24Y4C-E supports Cisco StackWise Virtual system virtualization rather than traditional access-switch physical stacking. Two compatible Catalyst 9500 switches are deployed as a virtual switching system for higher availability and simpler logical operation. It is not used like a Catalyst 9300 access stack with multiple closet switches connected through stack cables.
C9500-24Y4C-E is used for high-speed campus core, distribution, aggregation, and server access designs. The 24 SFP28 ports aggregate 10G or 25G links from access, distribution, or compute layers, while four QSFP28 ports carry 40G or 100G uplinks. Network teams select it when a fixed 1U platform fits the topology better than a modular chassis.
C9500-24Y4C-E suits medium to large enterprise networks that need dense 25G fiber connectivity and multiple 100G uplinks in a fixed form factor. It is most relevant where access blocks, distribution switches, or server racks require higher bandwidth than 10G uplinks provide. Smaller sites with only copper endpoints usually fit Catalyst access switches better.
C9500-24Y4C-E fits routed aggregation, high-volume east-west traffic, collapsed core designs, and 25G handoffs from server or distribution layers. Its 2.0 Tbps switching capacity and 1 Bpps forwarding rate support designs with concentrated uplink traffic. The switch is not a PoE edge platform, so endpoint power and copper access remain separate design layers.
C9500-24Y4C-E works in redundant core and distribution designs when paired with compatible Catalyst 9500 hardware, dual uplinks, routing protocols, and high-availability design practices. The platform supports StackWise Virtual on Catalyst 9500 models, plus redundant power supply options and field-replaceable cooling. Engineers commonly use dual switches to avoid a single fixed chassis becoming the aggregation point of failure.
C9500-24Y4C-E uses SFP28 optics or DACs for the 24 1/10/25G ports and QSFP28 or compatible QSFP modules for the four 40/100G uplinks. Cisco directs buyers to the Transceiver Module Group compatibility matrix for current optic support. Common design choices include Cisco SFP-10G, SFP-25G, QSFP-40G, and QSFP-100G families where supported.
C9500-24Y4C-E integrates with the Cisco Catalyst 9000 ecosystem, including Catalyst 9200, Catalyst 9300, Catalyst 9400, Catalyst 9500, and Catalyst 9600 designs. It runs Cisco IOS XE and fits Cisco Catalyst Center operations. Authentication, segmentation, and policy workflows often involve Cisco ISE, while adjacent switching links use standards-based Ethernet, VLAN, routing, and EtherChannel designs.
C9500-24Y4C-E is relevant to Ethernet designs using 1G, 10G, 25G, 40G, and 100G interfaces, VLAN trunking, link aggregation, routing, QoS, and ACL-based policy. Its SFP28 and QSFP28 ports align with fiber and direct-attach cabling standards. Protocol availability should be checked against the chosen Cisco IOS XE release and Network Essentials feature set.
C9500-24Y4C-E supports two power supply slots and uses high-performance Catalyst 9500 power options such as C9K-PWR-650WAC-R, C9K-PWR-650WACL-R, and C9K-PWR-930WDC-R where appropriate. Cisco also lists C9K-T1-FANTRAY support for C9500-24Y4C. Rack kits, SSD options, optics, and power cords should be matched to the exact deployment and region.
C9500-24Y4C-E and C9500-24Y4C-A use the same 24-port 1/10/25G SFP28 hardware with four 40/100G QSFP28 uplinks. The key difference is licensing: C9500-24Y4C-E ships with Network Essentials, while C9500-24Y4C-A ships with Network Advantage. Buyers choose the -A model when the design requires Advantage-tier features and the matching software subscription.
C9500-24Y4C-E provides 24 SFP28 1/10/25G ports and four QSFP28 40/100G uplinks, while C9500-48Y4C-E doubles the SFP28 port count to 48 with the same four high-speed uplinks. The 24-port model fits lower-density aggregation or server access rows. The 48-port model fits designs where more 25G handoffs terminate in one fixed switch.
C9500-24Y4C-E focuses on 25G SFP28 downlinks with four 40/100G QSFP28 uplinks. C9500-32C-E focuses on 32 QSFP28 ports supporting 40G or 100G connectivity. The 24Y4C model fits mixed 10G/25G aggregation, while the 32C model fits dense 100G aggregation or core designs with more high-speed QSFP28 endpoints.
C9500-24Y4C-E is the higher-speed choice for 25G SFP28 access or aggregation with fixed 40/100G QSFP28 uplinks. C9500-40X-E is a 40-port 1/10G SFP/SFP+ Catalyst 9500 model with modular uplink options. The 40X model suits 10G fiber aggregation, while the 24Y4C model suits 25G refreshes and 100G uplink designs.
C9500-24Y4C-E pricing depends on condition, quantity, optics, power supplies, software subscription selection, warranty term, and current channel availability. ORM Systems typically quotes enterprise switching projects individually so buyers receive the correct hardware bundle rather than a generic list price. The most accurate price request should include required optics, country, delivery timeline, and quantity.
C9500-24Y4C-E is commonly sourced as new, refurbished, or surplus enterprise hardware depending on market supply at the time of quotation. Refurbished units are especially relevant for network expansions, spares, and like-for-like replacements. Buyers should specify acceptable condition, power supply type, rail kit needs, optics, and support expectations when requesting availability from ORM Systems.
C9500-24Y4C-E appears in current Cisco Catalyst 9500 ordering information and is listed with the Network Essentials bundle. Lifecycle status should still be checked at the time of purchase against Cisco lifecycle notices, because enterprise switching statuses change by region, software train, and support policy. ORM Systems can quote available condition options around current supply.
C9500-24Y4C-E lead time depends on current stock, required condition, optics, accessories, and destination. A simple switch-only order may move faster than a fully matched bundle with transceivers, redundant power supplies, rack kits, and software items. Buyers with project deadlines should include target delivery date and configuration details in the quote request.
Bulk pricing is relevant for C9500-24Y4C-E when a project needs multiple core or distribution switches, matching spares, or standardized 25G aggregation across several locations. ORM Systems can price quantities, condition mixes, optics, and warranty terms together. A consolidated request usually produces a clearer commercial comparison than separate one-unit quotes for each site.
C9500-24Y4C-E may be supplied with ORM Systems warranty options up to 3 years depending on condition and availability. Warranty coverage should be confirmed on the quotation because refurbished, surplus, and new-channel units can carry different support paths. Buyers should also decide whether Cisco Smart Net Total Care, Cisco CX support, or internal sparing is required.
Refurbished C9500-24Y4C-E switches should be tested for boot status, port operation, management access, fans, power supply behavior, and visible hardware condition before dispatch. For this SKU, checks should include SFP28 interfaces, QSFP28 uplinks, console access, IOS XE status, and accessory matching. Test records and serial details are useful for asset teams receiving refurbished enterprise switches.
C9500-24Y4C-E buyers normally review Cisco platform compliance for safety, electromagnetic compatibility, environmental rules, and regional power requirements. RoHS, EMC, and country-specific approvals should be validated through Cisco documentation and the exact shipment configuration. For regulated procurement, the quote pack should include SKU, serial details where available, condition, power cords, and warranty documentation.
C9500-24Y4C-E first-use configuration requires console or management access, an approved Cisco IOS XE image, interface planning, routing design, VLAN or Layer 3 handoff definitions, management IP addressing, and licensing readiness. Engineers also prepare optics, DACs, power supplies, rack mounting, and out-of-band access before production insertion. Configuration should follow the target core or distribution topology.
C9500-24Y4C-E includes the Network Essentials network stack bundle, and Cisco ordering guidance states that a matching Catalyst or Cisco DNA software subscription is mandatory for new orders. The exact term and subscription SKU should be aligned with procurement policy. Feature planning should confirm whether Network Essentials meets the design or whether C9500-24Y4C-A with Network Advantage is required.
C9500-24Y4C-E deployments commonly require compatible SFP28 and QSFP28 optics or DACs, fiber cabling, rack mounting hardware, power cords, optional redundant power supply, management cabling, and console access. Design teams should also prepare IP addressing, routing templates, monitoring targets, and maintenance windows. For high availability, paired switches and matching uplink optics are usually planned together.
C9500-24Y4C-E is available in the UK through ORM Systems for enterprise hardware buyers seeking Cisco Catalyst switching equipment. ORM Systems can quote the switch with new or refurbished condition options, compatible optics, accessories, and warranty coverage. UK buyers should request the exact C9500-24Y4C-E SKU so the Network Essentials bundle and port configuration are matched correctly.
ORM Systems supports international purchasing conversations for C9500-24Y4C-E, subject to product availability, export requirements, destination, service level, and logistics details. International buyers should provide delivery country, business details, required condition, power cord region, optics list, and target delivery date. A complete configuration helps avoid delays around customs paperwork, accessory matching, and freight selection.
