C9300-48UXM-E is a Cisco Catalyst 9300 Series managed Layer 3 access switch built for multigigabit copper edge ports with Cisco UPOE. It provides 48 fixed RJ-45 downlinks: 36 ports support 100M, 1G, and 2.5G, while 12 multigigabit ports support 100M, 1G, 2.5G, 5G, and 10G. The uplink bay is modular and ships without a network module installed; supported Cisco Catalyst 9300 module options include RJ-45 multigigabit, SFP, SFP+, SFP28, and QSFP uplink types through C9300-NM family modules. The 1U rack-mount chassis uses AC power, dual redundant power supply support is optional, and the port layout targets access closets where standard 2.5G endpoints and higher-speed wireless devices share the same switch. C9300-48UXM-A is the closest hardware sibling, with the documented difference that it ships with Network Advantage instead of Network Essentials.
580 Gbps switching capacity supports dense access aggregation across the mixed 2.5G and 10G copper downlink set. 431.54 Mpps forwarding rate keeps packet handling aligned with the fixed access port profile, while 1060 Gbps stacked switching capacity applies when compatible Catalyst 9300 members operate as a StackWise-480 stack. 490W PoE budget is available with the default 1100W AC power supply, so engineers allocate Cisco UPOE power across endpoints according to device draw rather than assuming every port consumes the maximum at once. C9300-48UXM-E includes 8 GB DRAM, 16 GB flash, a 32,000-entry MAC table, an RJ-45 Ethernet management interface, RJ-45 console access, USB storage support, and SNMPv1, SNMPv2c, and SNMPv3 management. Network Essentials documents routed access with static routing, RIPv1, RIPv2, RIPng, OSPF for 1000 routes, EIGRP Stub, PBR, and PIM Stub Multicast. STP/RSTP/MSTP, LACP, PVLAN, VRRP, CDP, QoS, 802.1X, MACsec-128, CoPP, SXP, and SSO sit within the switch fundamentals feature set.
C9300-48UXM-E fits the enterprise access tier for wiring closets serving Wi-Fi access points, powered cameras, collaboration endpoints, workstations, and other copper edge devices that benefit from 2.5G or 10G speeds. StackWise-480 supports eight-switch stacks, and the 44 mm rack-mount body occupies 1U in standard equipment racks, leaving uplink selection to the chosen network module. ORM Systems supplies this switch new and certified refurbished, with refurbished units checked for boot status, port negotiation, UPOE delivery, fan health, power supply status, stacking readiness, and module recognition before dispatch. Request a quote from ORM Systems with target condition, quantity, power supply, regional power cord, StackWise cable, and uplink module requirements. Enterprise and volume buyers receive matched configurations, consistent accessory selection, warranty coverage, and delivery planning across multi-closet Catalyst refreshes, staged upgrades, and spare-unit requirements. Quote scope includes lifecycle replacement planning for sibling Network Essentials units and standardized labeling for access closet rollout records.
C9300-48UXM-E price is $3,556.00, a 76.2% saving from the Cisco list price of $14,914.00. C9300-48UXM-E is in stock and available for next-day dispatch. (terms applied)

C9300-48UXM-E sits in an access closet and terminates copper runs from Wi-Fi access points, workstations, cameras, collaboration endpoints, and other powered devices. Engineers place standard endpoints on the 36 ports that support 100M, 1G, and 2.5G, then reserve the 12 multigigabit ports for devices requiring 5G or 10G copper. Cisco UPOE policies, VLANs, QoS, and authentication controls operate at this edge, with Network Essentials providing the base campus switching tier. The network gains denser powered access while matching port speed to endpoint demand.
The switch anchors the access layer and hands aggregated endpoint traffic northbound through a selected Catalyst 9300 network module. Engineers match C9300-48UXM-E with C9300-NM-8X, C9300-NM-2Q, C9300-NM-2Y, or another supported module according to the distribution design, optics plan, and oversubscription target. Downlinks remain fixed as 36 2.5G capable ports plus 12 10G multigigabit ports while uplinks change with the module, so distribution refresh plans stay decoupled from endpoint cabling. The network gains a cleaner refresh path without replacing copper endpoint cabling.
Several compatible Catalyst 9300 Network Essentials switches form a StackWise-480 block when a wiring closet needs more powered multigigabit ports under one control plane. C9300-48UXM-E contributes 48 Cisco UPOE access ports per member, a default 1100W AC power supply, and modular uplink selection for distribution connectivity. Engineers standardize stack cables, power supplies, network modules, VLAN templates, software releases, and Smart Licensing registration before adding members to the closet stack. The operation gains unified switch administration, coordinated uplink redundancy, and predictable growth across the access closet.

C9300-48UXM-E is a Cisco Catalyst 9300 Series stackable enterprise access switch with 48 Cisco UPOE copper ports, modular uplinks, and Network Essentials licensing. Its downlink mix includes 36 ports supporting 100M, 1G, and 2.5G, plus 12 multigigabit ports supporting 100M, 1G, 2.5G, 5G, and 10G for high bandwidth access endpoints.
C9300 identifies the Cisco Catalyst 9300 modular uplink family, 48 indicates 48 access ports, UXM identifies the multigigabit Cisco UPOE hardware variant, and E indicates Network Essentials. For C9300-48UXM-E, the hardware combines 36 2.5G capable copper ports with 12 ports that scale to 10G multigigabit speeds.
C9300-48UXM-E is a managed Ethernet access switch, not a standalone router, firewall, or wireless access point. It operates in Cisco Catalyst campus switching designs, terminates wired copper endpoints, powers Cisco UPOE devices, supports Layer 2 and Layer 3 switching functions, and uses optional Catalyst 9300 network modules for uplink connectivity.
C9300-48UXM-E sits in the Catalyst 9300 modular uplink access switching family, above fixed uplink Catalyst 9300L models and below newer higher performance Catalyst 9300X variants. It is designed for access closets that need Cisco UPOE, multigigabit copper, StackWise-480 stacking, and Network Essentials rather than Network Advantage licensing.
C9300-48UXM-E has 48 copper access ports. Cisco specifies 36 ports supporting 100M, 1G, and 2.5G, plus 12 multigigabit ports supporting 100M, 1G, 2.5G, 5G, and 10G. This port mix suits access designs that combine ordinary wired endpoints with higher speed access points, workstations, or uplinked edge devices.
C9300-48UXM-E provides 580 Gbps switching capacity and a 431.54 Mpps forwarding rate in standalone operation. With stacking, Cisco lists 1060 Gbps switching capacity and 788.69 Mpps forwarding rate. These figures place the model in the multigigabit Catalyst 9300 access class, where copper port speed and stack bandwidth both matter.
C9300-48UXM-E supports Cisco UPOE across its 48 copper access ports. The default PWR-C1-1100WAC-P power supply provides 490W available PoE, and additional or upgraded power supplies increase the available PoE budget. Cisco also lists support for 60W Cisco UPOE and IEEE 802.3bt Type 3 power profiles for the UPOE model class.
C9300-48UXM-E uses the Network Essentials perpetual license tier, which covers core Catalyst switching fundamentals, management automation, troubleshooting, and base Layer 2 and Layer 3 access switching functions. It runs Cisco IOS XE and fits campus access designs using VLANs, trunks, EtherChannel, QoS, ACLs, routing features, and Cisco Catalyst Center based operations.
C9300-48UXM-E runs Cisco IOS XE and fits Catalyst management workflows through CLI, SNMP, NETCONF, RESTCONF, YANG models, streaming telemetry, Cisco Smart Software Manager, and Cisco Catalyst Center. Cisco also lists Meraki software options for certain Catalyst 9300 models, but C9300-48UXM-E is the Network Essentials ordering SKU for traditional Catalyst licensing.
C9300-48UXM-E supports Cisco StackWise-480 as a Catalyst 9300 modular uplink model. Up to eight compatible C9300 switches with the same license level form a stack using dedicated StackWise cables. The stack operates with a single management and control plane, which simplifies access closet expansion and supports cross-stack operational consistency.
C9300-48UXM-E is used for high density access switching where endpoints need more than 1G copper or higher PoE power. It suits wiring closets serving Wi-Fi 6 or 802.11ac Wave 2 access points, powered cameras, thin clients, building systems, collaboration devices, and workstations that benefit from 2.5G or 10G multigigabit copper access.
C9300-48UXM-E fits enterprise campus and branch access environments that need 48 powered copper ports per switch and stackable expansion across a wiring closet. StackWise-480 supports up to eight compatible C9300 members, so operations teams use it where port density, common policy, redundant uplinks, and central switch administration are required.
C9300-48UXM-E matches access workloads that mix standard endpoint traffic with higher bandwidth or higher power requirements. The 36 2.5G capable ports handle dense wired access, while the 12 10G multigigabit ports serve faster edge devices or access points. Cisco UPOE supports powered endpoints without separate local power injectors.
C9300-48UXM-E works in stacked Catalyst 9300 access deployments using StackWise-480 cables. A stack of compatible C9300 models with the same license level presents one management plane, one control plane, and coordinated uplink planning. This deployment style reduces per-switch administration while expanding powered multigigabit copper capacity in repeated closet builds.
C9300-48UXM-E supports Catalyst 9300 modular uplink network modules such as C9300-NM-4G, C9300-NM-4M, C9300-NM-8X, C9300-NM-2Q, and C9300-NM-2Y. Cisco notes that Catalyst 3850 and Catalyst 9300 network modules are supported on Catalyst 9300 models, while C9300X network modules are only for Catalyst 9300X models, keeping module selection tied to the correct chassis generation.
C9300-48UXM-E uses StackWise cables for Catalyst 9300 modular uplink models, including STACK-T1-50CM, STACK-T1-1M, and STACK-T1-3M. These cables connect the rear stacking ports to form a StackWise-480 ring. C9300L stack kits are not the correct accessory family for modular uplink C9300 models, because fixed uplink models use different stacking hardware.
C9300-48UXM-E ships with a 1100W AC power supply, and Cisco lists PWR-C1-1100WAC-P as the default Platinum-rated option for this model class. It also supports dual redundant power supplies, with secondary or upgraded supplies increasing available PoE power for Cisco UPOE endpoint deployments and improving access closet power resilience.
C9300-48UXM-E fits Cisco Catalyst 9000 campus switching, Cisco IOS XE operations, Cisco Catalyst Center management, Cisco Smart Licensing, StackWise-480, StackPower, Cisco UPOE, PoE, PoE+, IEEE 802.3bt Type 3, VLAN, QoS, EtherChannel, NETCONF, RESTCONF, YANG, and streaming telemetry based operations. It is also ENERGY STAR certified as a C9300-48UXM model.
C9300-48UXM-E and C9300-48UXM-A use the same 48-port multigigabit Cisco UPOE hardware, including 36 2.5G capable ports and 12 10G multigigabit ports. The difference is licensing: C9300-48UXM-E ships with Network Essentials, while C9300-48UXM-A ships with Network Advantage for designs needing the Advantage feature set and matching DNA Advantage subscriptions.
C9300-48UXM-E provides 36 ports up to 2.5G plus 12 ports up to 10G, while C9300-48UN-E is listed as a 48-port 5G copper UPOE model with modular uplinks. C9300-48UN-E suits more uniformly high multigigabit access, while C9300-48UXM-E suits mixed 2.5G and 10G access requirements with Network Essentials licensing.
C9300-48UXM-E adds multigigabit copper access, with 36 ports up to 2.5G and 12 ports up to 10G. C9300-48U-E is the 48-port 1G copper Cisco UPOE Network Essentials model. The UXM model is the better match when powered access points or edge devices need copper speeds above 1G.
C9300-48UXM-E is a modular uplink Catalyst 9300 model with StackWise-480 and selectable uplink modules. C9300L-48UXG-4X-E is a fixed uplink Catalyst 9300L model with 12 multigigabit ports, 36 1G ports, and 4x 10G/1G SFP+ uplinks. C9300-48UXM-E fits designs that require modular uplink flexibility and higher stacking bandwidth.
C9300-48UXM-E is commonly sourced through enterprise hardware resellers in new, refurbished, or surplus condition depending on market supply. ORM Systems can position the SKU for buyers comparing factory sealed stock, tested refurbished units, and budget sensitive refresh options, while the technical requirement remains the same 48-port multigigabit Cisco UPOE Network Essentials switch.
C9300-48UXM-E price depends on condition, quantity, power supply configuration, included network module, licensing status, warranty term, and current channel availability. A unit with an uplink module, power cords, StackWise accessories, and tested refurbished warranty coverage prices differently from a bare chassis or new channel configuration.
C9300-48UXM-E belongs to the Cisco Catalyst 9300 Series, and Cisco publishes lifecycle notices by exact product or software item rather than one universal family date. Buyers should verify the exact SKU status at quote time. The current Cisco data sheet still lists C9300-48UXM-E in the ordering information for Network Essentials.
C9300-48UXM-E lead time depends on stock condition, configuration, testing queue, quantity, and destination. Refurbished stock is often faster when available because the base hardware already exists, while new or specific accessory bundles can require additional sourcing. ORM Systems quotes lead time against the requested condition and configuration.
Bulk pricing for C9300-48UXM-E is relevant when a refresh requires multiple access closet switches, consistent power supplies, matching network modules, and StackWise cables. Volume orders allow ORM Systems to source matched units, align testing and warranty terms, and quote a lower per-unit position when market availability supports it.
ORM Systems typically offers warranty options for enterprise networking hardware such as C9300-48UXM-E, with coverage depending on condition, availability, and order terms. Cisco also lists the Catalyst 9300 Series with Enhanced Limited Lifetime hardware warranty for eligible original purchases. Reseller warranty terms should be confirmed on the quote for each unit.
Refurbished C9300-48UXM-E units should be tested before dispatch for boot status, port operation, power supply health, fan operation, stacking readiness, and uplink module recognition when modules are included. This testing is especially important for multigigabit copper ports and Cisco UPOE delivery because access deployments rely on stable speed negotiation and power behavior.
C9300-48UXM-E is part of the Cisco Catalyst 9300 Series, and Cisco marks the C9300-48UXM model as ENERGY STAR certified. The platform also aligns with Ethernet and PoE standards used in enterprise access networks, including Cisco UPOE, PoE, PoE+, IEEE 802.3bt Type 3 power profiles, and standard VLAN and Ethernet switching protocols.
C9300-48UXM-E is normally staged through Cisco IOS XE with management IP addressing, administrator access, VLANs, trunks, access port templates, PoE policies, QoS, routing settings, and optional StackWise configuration. Engineers also verify the installed power supplies, network module, software release, Smart Licensing registration, and endpoint speed negotiation before production handoff.
C9300-48UXM-E includes the Network Essentials perpetual network license tier, and Cisco states that Catalyst 9300 models ordered with Network Essentials or Network Advantage also require a Cisco Catalyst or Cisco DNA subscription term license at configuration time. License planning should include Smart Account readiness, renewal dates, and the intended Catalyst Center feature set.
C9300-48UXM-E deployment commonly requires a compatible Catalyst 9300 network module, optics or DACs for uplinks, power cords for the installation region, optional secondary power supply, rack mounting hardware, StackWise cables for stacking, and console or management access. Cisco lists regional power cords such as CAB-TA-UK for United Kingdom installations.
Businesses can buy C9300-48UXM-E in the UK through ORM Systems as an enterprise hardware reseller supplying Cisco networking equipment. The quoting process should specify condition, required power supply, uplink module, accessories, warranty term, destination, and quantity so the switch arrives aligned to the access deployment plan.
ORM Systems supports international supply for enterprise IT hardware, including Cisco Catalyst switching SKUs such as C9300-48UXM-E, subject to stock, export rules, courier service, and destination requirements. International buyers should align power cords, warranty expectations, customs documentation, and accessory bundles before shipment to avoid deployment delays.
