C9300-48U-M is a Meraki-managed Layer 3 enterprise access switch with 48 Gigabit RJ-45 ports supplying UPOE in a 1U rack-mount chassis. Fiber uplinks require a separately ordered network module rather than using fixed, built-in uplink ports. The Catalyst 9300-M series serves campus and branch access where copper endpoints need connectivity and powered devices share the available power allocation. C9300-48P-M offers 30W PoE+ per port instead of this model's higher UPOE ceiling. Within the broader Catalyst 9000 family, this variant arrives with Meraki software for cloud management. The hardware configuration therefore combines Gigabit endpoint connections with an independently selected uplink arrangement, rather than bundling a fixed fiber-port configuration into the base unit.

256 Gbps switching capacity sets the standalone aggregate bandwidth ceiling for traffic planning. 190.48 Mpps forwarding is rated with 64-byte IPv4 packets, providing a separate packet-per-second measure for small-packet workloads. 822W of shared PoE capacity is available with the default PWR-C1-1100WAC-P supply; installing a second PWR-C1-1100WAC-P raises available endpoint power to 1800W. C9300-48U-M carries 8 GB of DRAM and 16 GB of flash for its software environment, separate from its 16 MB packet buffer. A MAC table holding 32000 entries defines hardware address scale, while the hardware IPv4 table accommodates 32000 total ARP and learned-route entries. Remote cable testing and packet capture complement dashboard configuration when troubleshooting endpoint connections. The 227410-hour MTBF is a reliability metric rather than an individual service-life commitment. Hardware-based IPsec acceleration is not supported by this hardware configuration.
ORM Systems supplies C9300-48U-M new sealed or Certified refurbished, with new-unit extended warranties up to 3 years, refurbished-unit warranties up to 1 year, and 30-day returns for either condition; terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and PoE output under load on every powered port, with firmware verified and configurations wiped to factory default. Specify condition, license, required accessories, and MA-PWR-CORD-US for US orders on the purchase order; Cisco's separate limited lifetime hardware warranty follows its own terms. POs are accepted, government buyers receive Net-30, and enterprise or volume orders can use RMA with advance replacement through UK, EU, US, and MEA regional stock and RMA.

When a powered-endpoint refresh includes devices drawing 60W, UPOE port capability is not the same as simultaneous power availability across all access ports. Build the endpoint power inventory from required device classes and concurrent loads, then specify the installed power configuration before issuing the purchase order.
During a multi-site rollout, configurations can be prepared before hardware arrives and templates can standardize the fleet through cloud management. That workflow depends on assigning the intended configuration rather than duplicating local device scripts. Confirm the receiving sites, template assignments, and predeployment settings before the purchase order.
When extending a stack that must share available power, data-stack connections and power-sharing connections are separate requirements. StackPower uses CAB-SPWR-30CM-M or CAB-SPWR-150CM-M to pool supply capacity across the stack. Check member placement and the required power-sharing cable length before adding accessories to the purchase order.
Multigigabit copper endpoint connections
C9300-48U-M limits copper access links to 1G. C9300-48UXM-M provides 36 ports at 2.5G plus 12 Multigigabit ports reaching 10G, while retaining 48-port density.
90W power for individual endpoints
C9300-48U-M stops at 60W UPOE per port. C9300X-48HX-M supports 90W UPOE+ and 48 Multigigabit access ports, so the alternative also changes downlink speed.
Fixed fiber uplinks in base unit
C9300-48U-M needs a separately ordered network module for fiber uplinks. C9300L-48PF-4X-M includes four 10G fixed uplinks but provides PoE+ rather than UPOE endpoint power.

C9300-48U-M identifies a Catalyst 9300 switch with 48 Gigabit copper UPOE ports, modular uplinks, and Meraki software. C9300 names the hardware family, 48 indicates the access-port count, U indicates UPOE, and M identifies Meraki mode. Enterprise or Advanced licensing is selected separately.
C9300-48U-M is managed through the Meraki dashboard, with configuration and monitoring performed natively in the cloud interface. Administrators can prepare configurations before delivery and use templates across a fleet. Dashboard troubleshooting includes remote cable testing, packet captures, and a dynamic network topology view.
Cisco has not announced an end-of-sale date for Catalyst 9300-M. C9300-48U-M continues to be offered as a Meraki-mode hardware configuration. Hardware lifecycle and cloud-license expiration are separate purchase considerations; selecting new or refurbished hardware does not remove the need for a dashboard license.
ORM Systems offers C9300-48U-M new sealed or Certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Cisco's separate limited lifetime hardware warranty follows its own terms. Returns are available for 30 days in either condition; terms apply.
C9300-48U-M supports Meraki co-term Enterprise or Advanced licenses and Meraki subscription Essentials or Advantage licenses, each starting at 1 year. Co-term options run for 1, 3, 5, 7, or 10 years; subscription terms range from 1 to 10 years. Hardware condition does not replace the dashboard licensing requirement.
C9300-48U-M provides a shared 822W PoE budget with its default PWR-C1-1100WAC-P supply, and 1800W with two PWR-C1-1100WAC-P supplies. UPOE supports 60W per port, but 48 ports at that level would require 2880W. Endpoint totals therefore need to be allocated within the installed power configuration.
Catalyst 9300-M accepts C9300-NM-8X-M for eight 1G/10G uplinks, C9300-NM-2Y-M for two 1G/10G/25G uplinks, and C9300-NM-2Q-M for two 40G uplinks. C9300-48U-M has no fixed fiber uplinks; the selected network module is ordered separately. Match the module interfaces to the required uplink speed before adding optics to the purchase order.
C9300-48U-M supports eight members in a StackWise-480 data stack with 480 Gbps stacking bandwidth. STACK-T1-50CM-M provides a 0.5 m data-stack connection. Catalyst 9300-M can stack with Catalyst 9300X-M at 480 Gbps, while fixed-uplink Catalyst 9300L-M models cannot join that modular-uplink stack.
Yes, Catalyst 9300-M is a 1U rack-mount switch, and rack-mount brackets are included in its base package. C9300-48U-M measures 44 mm high, 445 mm wide, and 488 mm deep with PWR-C1-1100WAC-P installed, and weighs 7.72 kg. Allow installation clearance beyond the chassis dimensions when specifying the rack.
C9300-48U-M supports 60W UPOE per port, while C9300-48P-M supports 30W PoE+ per port. Both are 48-port Gigabit Meraki-mode switches with modular uplinks. Choose the UPOE model for endpoints requiring the higher per-port ceiling; choose the PoE+ model when endpoint specifications stay within the lower ceiling.
C9300-48U-M uses Meraki software with a separately selected cloud license, while C9300-48U-E carries the perpetual Network Essentials license. The difference concerns the software entitlement supplied with the hardware. The M model suits a Meraki-mode order; the E model suits buyers specifying Network Essentials in their switching standard.
C9300-48U-M has 48 Gigabit UPOE access ports, while C9300-24U-M has 24. Both offer Meraki mode and modular uplinks. The 48-port model suits closets requiring greater copper-port density; the 24-port model suits an endpoint inventory that fits within the smaller port configuration without specifying additional access capacity.
No, C9300-48U-M does not provide hardware-based IPsec acceleration. The Catalyst 9300 modular-uplink hardware configuration lacks that capability regardless of the selected cloud license. Uplink-module selection and UPOE power allocation address separate requirements and do not add IPsec acceleration to this switch.
