C9300X-48HX-A Overview
C9300X-48HX-A is a Cisco Catalyst 9300X managed Layer 3 stackable copper switch built for access networks that need dense multigigabit client ports and high-power PoE from one chassis. The fixed access side provides 48 10G/5G/2.5G/1G/100M RJ-45 multigigabit ports with Cisco UPOE+ for powered endpoints. Uplinks are handled by an empty modular bay, so uplink ports are added only after selecting a Catalyst 9300X network module such as C9300X-NM-8M, C9300X-NM-8Y, C9300X-NM-2C, or C9300X-NM-4C. The 1U Catalyst 9300X chassis ships with a 1100W default AC supply and Network Advantage licensing. Compared with C9300X-48HX-E, this SKU keeps the same 48-port 10G/mGig UPOE+ hardware and changes the order to Network Advantage. It targets closets replacing 1G access while keeping copper cabling and powered endpoint workflows intact.
1760 Gbps switching capacity gives the 48-port multigigabit access block backplane capacity for high-density endpoint and uplink designs before stacking. 2760 Gbps switching capacity with stacking raises the aggregate profile for StackWise-1T deployments that combine multiple Catalyst 9300X members. 1309 Mpps forwarding rate aligns the platform with campus access designs that carry Wi-Fi 6/6E access points, cameras, sensors, workstations, and local aggregation traffic. 590W available PoE from the default 1100W AC power supply supports UPOE+ endpoint planning, with higher budgets available when secondary supplies are added according to Cisco power tables. C9300X-48HX-A also carries 16 GB DRAM, 16 GB flash, a 32,000-entry MAC table, 32 MB packet buffer, Cisco IOS XE management, Smart Licensing, Catalyst Center workflows, and Meraki dashboard monitoring where the selected operating mode supports it. Network Advantage also brings advanced routing, segmentation, automation, resiliency, IoT integration, and MACsec-256 into the license tier, which matters when access switching participates in policy-driven campus designs and fabric operations planning.
This switch belongs at the enterprise access layer where high-speed copper ports feed powered Wi-Fi access points, collaboration devices, cameras, sensors, and workstation drops. StackWise-1T lets matching Catalyst 9300X members share one stack control plane, while the 1U rack design preserves cabinet space for patching, power, and uplink hardware. ORM Systems supplies C9300X-48HX-A in new and certified refurbished condition for access refreshes, spares, and staged rollouts. Refurbished units are checked for multigigabit link negotiation, UPOE+ delivery, modular-uplink detection, fan status, power-supply health, StackWise readiness, and IOS XE boot behavior before dispatch. Confirming secondary power supplies, rack airflow, and uplink optics during procurement helps avoid access-layer rework after staging and acceptance testing.

C9300X-48HX-A Use Case
High-Density Powered Access
C9300X-48HX-A sits in the powered access layer where 48 10G multigigabit RJ-45 ports feed Wi-Fi access points, collaboration endpoints, cameras, sensors, and workstations from one Catalyst 9300X stack member. Engineers map UPOE+ power classes, assign access VLANs, apply QoS for voice and wireless traffic, and reserve the modular bay for the selected upstream module. Network Advantage supports the routed access and segmentation features chosen for the site design. The access block gains dense copper speed, endpoint power, and consistent Catalyst policy enforcement across the wiring closet stack.
Access to Distribution Handoff
The switch operates as an access-to-distribution handoff when a wiring closet needs multigigabit copper at the edge and high-speed modular uplinks toward distribution. The 48 fixed ports absorb endpoint and AP connections, while C9300X-NM module selection defines the upstream path as 10G, 25G, 40G, or 100G. Engineers validate PoE allocation, VLAN trunks, routing adjacency, and StackWise-1T membership before production. This placement reduces access bottlenecks while keeping uplink media aligned with the campus aggregation design for each distribution-facing uplink group handoff.
Stack Refresh and Standardization
C9300X-48HX-A supports standardized stack refresh work where access closets move from 1G copper to 10G multigigabit service without changing the Catalyst operating model. Teams stage IOS XE, Smart Licensing, Catalyst Center discovery, StackWise cabling, and power-supply redundancy before replacing legacy access members. UPOE+ budgets are checked against wireless and device inventories, and refurbished units receive port, PoE, fan, PSU, and boot validation before shipment. The refresh delivers faster powered access with a manageable stack boundary while preserving familiar Catalyst change-control and support practices.
