C9300-48U-A combines Cisco UPOE access power with the Network Advantage software tier in a managed Layer 3 switch for enterprise wiring closets. The switch provides 48 fixed 1GbE RJ-45 downlink ports, and its uplink position is an empty modular bay that accepts RJ-45, SFP, SFP+, SFP28, and QSFP network module options rather than a preinstalled uplink set. Cisco UPOE support supplies powered access for higher-draw endpoints from a rack-mount 1U member of the Cisco Catalyst 9300 Series. It fits copper access closets where standard 1G endpoint cabling stays in place while the power class, routed access policy, and software tier move beyond PoE+ or Network Essentials access builds without changing the access switching series. The closest license sibling, C9300-48U-E, keeps the same 48-port 1G UPOE hardware profile but carries Network Essentials instead of Network Advantage.
256 Gbps switching capacity delivers wire-speed access aggregation for the fixed Gigabit Ethernet downlinks before traffic moves through the selected uplink module. 190.48 Mpps forwarding rate supports campus endpoint traffic at Layer 2 and routed access boundaries. 822W PoE budget is shared across the 48 powered ports, so access point, phone, camera, and client loads should be allocated against the installed power design. 736 Gbps stacked switching capacity supports larger access blocks when compatible Catalyst 9300 members operate as one stack. OSPF, BGP, EIGRP, HSRP, IS-IS, VRF, VXLAN, LISP, TrustSec, SGT, MPLS, and mVPN align the Network Advantage image with advanced campus routing and segmentation. C9300-48U-A also carries 8 GB DRAM, 16 GB flash, a 32000-entry MAC table, IOS XE management, NETCONF, RESTCONF, gRPC, YANG, PnP Agent, and ZTP/Open PnP automation support. The hardware platform supports StackPower planning for shared power resources across compatible modular uplink stack members.
At the enterprise access tier, C9300-48U-A connects IP phones, wireless access points, surveillance cameras, badge readers, printers, and workstations while handing uplink traffic toward distribution through the chosen module. StackWise-480 stacking expands the closet into a single control plane, and the 1U chassis preserves rack density for repeated access-layer builds across multiple floors or sites. ORM Systems supplies this model new and certified refurbished, with refurbished units checked for port link, UPOE delivery, fan status, power supply health, module recognition, and clean configuration state before dispatch. Request a quote for unit pricing, matched power supplies, uplink modules, stacking accessories, and volume supply planning. Enterprise buyers gain a clearer path to standardised Catalyst 9300 sourcing across refresh, expansion, spare-stock requirements, serial tracking, consistent configuration, staged deployments, and long-term maintenance planning.
C9300-48U-A price is $2,293.00, a 81.7% saving from the Cisco list price of $12,518.00. C9300-48U-A is in stock and available for next-day dispatch. (terms applied)

C9300-48U-A sits in a wiring closet and terminates copper runs from phones, cameras, workstations, badge readers, and access points on 48 1G Cisco UPOE ports. Engineers assign VLANs, 802.1X controls, QoS markings, and PoE policies at the edge, then hand traffic northbound through a selected Catalyst 9300 network module. The 822W default PoE budget supports dense powered endpoint groups when loads are calculated during design. The access layer gains predictable endpoint power and policy enforcement without replacing copper cabling.
The switch operates as a routed access boundary where endpoint VLANs terminate close to the closet instead of stretching across distribution. Network teams use the C9300-48U-A Network Advantage tier for advanced routing and segmentation services such as OSPF, BGP, VRF, VXLAN, LISP, TrustSec, and SGT where the campus design requires them. UPOE access ports keep powered endpoints on the same policy edge as routing decisions. The network gains tighter failure domains, cleaner route ownership, and clearer segmentation between access blocks.
Multiple Catalyst 9300 modular uplink switches form a StackWise-480 access block when a closet needs more 1G powered ports under one control plane. C9300-48U-A contributes 48 Cisco UPOE ports per member, while StackPower planning pools power supplies across compatible stack members for redundancy or supplemental power. Engineers place uplinks on different stack members and align IOS XE releases, license levels, stack cables, and power budgets before production cutover. The closet gains higher access density with consistent management and resilient uplink placement.

Cisco C9300-48U-A is a Catalyst 9300 Series stackable enterprise access switch with 48 1G copper ports, Cisco UPOE, modular uplinks, and the Network Advantage license tier. It is designed for campus access closets that need dense powered Ethernet for phones, wireless access points, cameras, and other endpoints while keeping uplink selection separate through optional network modules.
C9300 identifies the Cisco Catalyst 9300 modular uplink switch family, 48 indicates 48 downlink ports, U indicates Cisco UPOE support, and A indicates the Network Advantage license tier. For ordering, C9300-48U-A refers to the 48-port 1G copper UPOE model rather than the PoE+, data-only, multigigabit, or Meraki-managed variants in the same family.
C9300-48U-A is a managed Layer 2 and Layer 3 Ethernet switch for enterprise access networks. It is not a router, firewall, wireless access point, or standalone PoE injector. The switch terminates copper endpoint connections at the access layer, applies campus switching policy, and forwards traffic toward distribution or core switches through a separately ordered Cisco Catalyst 9300 network module.
C9300-48U-A sits in the Catalyst 9300 modular uplink access switching lineup, above fixed-uplink Catalyst 9300L models and below newer Catalyst 9300X platforms for higher multigigabit and 90W UPOE+ density. It suits networks that need 48 1G UPOE access ports, StackWise-480 stacking, StackPower, and Network Advantage software features without moving to a 9300X chassis.
C9300-48U-A has 48 copper downlink ports for 10/100/1000 Ethernet access connections with Cisco UPOE power support. The base switch uses modular uplinks rather than fixed uplinks, so the uplink interfaces depend on the selected Catalyst 9300 network module. Common choices include C9300-NM-4G, C9300-NM-8X, C9300-NM-2Q, and C9300-NM-2Y modules.
C9300-48U-A provides 256 Gbps switching capacity and 190.48 Mpps forwarding rate as a standalone switch. In a stacked design, Cisco lists 736 Gbps switching capacity with stacking and 547.62 Mpps forwarding rate with stacking for the C9300-48U platform. These figures help size access closets where powered endpoints aggregate toward higher speed distribution uplinks.
C9300-48U-A supports Cisco UPOE across 48 1G copper access ports. With the default PWR-C1-1100WAC-P power supply, Cisco lists 822W of available PoE power for the C9300-48U platform. Additional or higher-capacity power supplies change the available power budget, so access point, camera, phone, and thin client loads should be calculated before ordering.
C9300-48U-A ships with the Network Advantage tier, which supports advanced switching, routing, and segmentation functions beyond the Network Essentials tier. Cisco lists Network Advantage support for features such as BGP, EIGRP, HSRP, IS-IS, OSPF, VRF, VXLAN, LISP, Cisco TrustSec, SGT, MPLS, and mVPN on Catalyst 9300 Series switches where the design uses those services.
C9300-48U-A runs Cisco IOS XE and fits into standard Catalyst management workflows. Network teams manage it through the IOS XE CLI, SNMP monitoring, syslog, NETCONF or RESTCONF automation, and Cisco Catalyst Center for controller-based campus operations. The Network Advantage tier also aligns with policy, segmentation, and software-defined access designs that require deeper campus feature coverage.
C9300-48U-A supports StackWise-480 as part of the Catalyst 9300 modular uplink family. Up to eight compatible Catalyst 9300 switches form a single logical stack with 480 Gbps stacking bandwidth, shared management, and distributed forwarding. The platform also supports Cisco StackPower for power pooling across compatible modular uplink stack members when the proper StackPower cables and power design are used.
C9300-48U-A is used for enterprise access switching where a wiring closet needs many powered 1G copper connections. It commonly aggregates IP phones, Wi-Fi access points, surveillance cameras, badge readers, printers, and workstations into VLANs and routed access designs. Its UPOE budget and modular uplinks make it useful when endpoint power demand and upstream bandwidth must be planned together.
C9300-48U-A fits medium to large campus access environments that standardize on Cisco Catalyst switching and need 48 powered copper ports per rack unit. A single unit serves one dense closet, while StackWise-480 designs scale port count across multiple switches under one management plane. The switch is strongest where policy, PoE power, and routed access features matter more than multigigabit downlinks.
C9300-48U-A suits endpoint access workloads that combine data, power, segmentation, and predictable uplink handoff. It is appropriate for Wi-Fi 5 or Wi-Fi 6 access points using 1G uplinks, Cisco IP phones, security cameras, compact clients, and mixed office endpoints. Network Advantage features also support routed access, VRFs, and policy-based designs in larger campus architectures.
C9300-48U-A works in routed access designs when the network team uses the Network Advantage feature set for advanced routing and segmentation. The switch places Layer 3 boundaries close to endpoint closets, applies VLAN and policy controls at the edge, and hands summarized or routed traffic northbound through the chosen uplink module. This reduces Layer 2 stretch across distribution blocks.
C9300-48U-A uses Cisco Catalyst 9300 modular uplink slots and supports Catalyst 9300 network modules such as C9300-NM-4G for 4x 1G, C9300-NM-8X for 8x 10G or 1G, C9300-NM-2Q for 2x 40G, and C9300-NM-2Y for 2x 25G, 10G, or 1G. Catalyst 9300X-only modules should not be treated as direct replacements for this model.
C9300-48U-A integrates with Cisco Catalyst Center, Cisco IOS XE operational tooling, Cisco Identity Services Engine for 802.1X and TrustSec policy, and Catalyst 9300 StackWise-480 designs. It also supports standards-based interoperability through Ethernet, VLAN trunks, EtherChannel, SNMP, syslog, RADIUS, TACACS+, NETCONF, RESTCONF, and routing protocols used in enterprise campus networks.
C9300-48U-A stacks with compatible Catalyst 9300 modular uplink models using StackWise-480 when license levels and hardware requirements are aligned. Cisco documents mixed stacking among Catalyst 9300 variants such as data, PoE+, UPOE, fiber, and multigigabit models. Stack members should be planned with matching software releases, stack cables, power supplies, and uplink redundancy across different physical switches.
C9300-48U-A supports common enterprise Ethernet and campus control standards, including VLANs, 802.1X, QoS, EtherChannel, IPv4 and IPv6 forwarding, MACsec-128 in the base feature table, and advanced routing and segmentation under Network Advantage. Cisco lists Network Advantage support for BGP, EIGRP, OSPF, IS-IS, VRF, VXLAN, LISP, TrustSec, SGT, MPLS, and mVPN.
C9300-48U-A and C9300-48U-E use the same 48-port 1G Cisco UPOE hardware profile with modular uplinks and a 1100W AC default power supply. The difference is software tier: C9300-48U-A includes Network Advantage, while C9300-48U-E uses Network Essentials. The Advantage SKU fits designs needing advanced routing, segmentation, and SD-Access-oriented features.
C9300-48U-A provides 48 1G copper ports with Cisco UPOE, while C9300-48P-A provides 48 1G copper ports with PoE+. Both are Catalyst 9300 modular uplink switches with Network Advantage. C9300-48U-A is the stronger match where endpoints need higher power delivery than PoE+ budgets normally support, such as power-hungry access points or specialized edge devices.
C9300-48U-A is the 48-port 1G Cisco UPOE model, while C9300-48H-A is the 48-port 1G Cisco UPOE+ model with Network Advantage. Both use modular uplinks and a 1100W AC default supply. C9300-48H-A targets higher 90W UPOE+ endpoint density, while C9300-48U-A suits 60W Cisco UPOE access designs.
C9300-48U-A provides 48 1G copper UPOE ports, while C9300-48UXM-A adds multigigabit access capability with 36 ports at 100M, 1G, or 2.5G and 12 ports up to 10G, 5G, 2.5G, 1G, or 100M. Both use Network Advantage and modular uplinks. C9300-48UXM-A fits higher speed access point refreshes, while C9300-48U-A fits 1G powered edge refreshes.
C9300-48U-A is typically sourced through enterprise reseller channels in new, surplus, and refurbished condition depending on market availability. ORM Systems listings and quotes should identify the supplied condition before purchase. Refurbished units are usually selected for cost-sensitive Catalyst refreshes, spare stock, or lifecycle extension where the required 48-port UPOE hardware remains architecturally correct.
C9300-48U-A pricing is affected by condition, included license entitlement, power supply configuration, uplink module selection, stacking accessories, warranty term, and order quantity. New units normally price differently from refurbished or excess stock. Buyers comparing quotes should confirm whether the switch includes only the base chassis or also optics, network modules, stack cables, StackPower cables, and support coverage.
C9300-48U-A still appears in Cisco Catalyst 9300 Series ordering information as the 48-port 1G copper UPOE modular uplink switch with Network Advantage. Lifecycle status should be checked against Cisco notices at the time of purchase, because availability and software milestones change. The product remains relevant for Catalyst 9300 access refreshes and sparing plans.
C9300-48U-A lead time depends on live reseller stock, requested condition, configuration, testing queue, and destination. Refurbished or in-stock surplus units usually move faster than back-to-back new procurement, while bulk orders need additional allocation checks. A quote should confirm dispatch timing, included accessories, serial-number requirements, and any staging or testing requested before shipment.
Bulk pricing is commonly requested for C9300-48U-A when multiple access closets, stack members, or spare units are being purchased together. Volume quotes should align the switch condition, license tier, uplink modules, power supplies, stack cables, and warranty terms across all units. Consistent configuration reduces deployment variance and makes receiving, staging, and support easier for network operations teams.
ORM Systems warranty coverage for C9300-48U-A should be confirmed on the quote because term and coverage can vary by condition and supply route. The meta guidance for switch pages allows up to 3-year warranty language where applicable. Buyers should verify whether warranty covers hardware replacement only, advance replacement, accessories, power supplies, network modules, and refurbished testing documentation.
Refurbished C9300-48U-A units should be tested for boot status, port operation, PoE delivery, fan and power supply health, module bay recognition, stacking interfaces, and cosmetic grade before dispatch. For deployment confidence, buyers should request confirmation of IOS XE version, erased configuration, serial numbers, included power supplies, and any optional uplink or stacking accessories supplied with the unit.
C9300-48U-A belongs to the Cisco Catalyst 9300 Series, which Cisco documents with safety and compliance information for enterprise switching deployments. Exact regulatory markings can vary by region and revision, so buyers should validate the Cisco compliance table, country requirements, power cord type, and import documentation before shipment. The switch uses enterprise Ethernet standards rather than carrier chassis certification assumptions.
C9300-48U-A first-use configuration requires console or management access, an IOS XE image appropriate for the environment, management IP settings, admin credentials, VLANs, trunks or routed interfaces, PoE policies, and uplink module configuration. Stack deployments also require compatible StackWise-480 cables, stack numbering, software alignment, and planned uplink placement across stack members.
C9300-48U-A is ordered with Network Advantage as the permanent network stack tier, and Cisco Catalyst or DNA software subscription requirements should be validated for the intended management and feature model. Designs using SD-Access, advanced assurance, or subscription-enabled software services should confirm the correct Cisco licensing before purchase. The A suffix should not be treated as a standalone DNA subscription term.
C9300-48U-A accessory planning should include the correct AC power cords, optional second power supply, Catalyst 9300 uplink network module, optics or DAC cables for uplinks, StackWise-480 cables, StackPower cables, rack ears, console access, and any spare fans or power supplies. Ordering these items with the switch avoids staging delays in access closet refresh projects.
C9300-48U-A can be bought in the UK through ORM Systems as a B2B IT hardware reseller for Cisco enterprise networking equipment. Buyers should request a quote that specifies condition, price, warranty, lead time, license tier, included power supply, and whether uplink modules or stacking accessories are bundled. This keeps the comparison between new and refurbished options clear.
ORM Systems can quote international supply for C9300-48U-A subject to destination, export requirements, carrier service, stock condition, and documentation needs. International buyers should confirm Incoterms, shipping cost, lead time, power cord type, import duties, warranty handling, and whether accessories such as uplink modules, optics, StackWise cables, or second power supplies are included in the same shipment.
