Cisco C9300-24U-M — Catalyst 9300 24-Port UPOE Switch with Modular Uplinks and Meraki Managed Software
What it is
C9300-24U-M is a Cisco Catalyst 9300 Series enterprise access switch with 24 × 1 Gigabit Ethernet UPOE-capable copper ports and a modular uplink slot.
The “-M” version is intended for Meraki cloud-managed operation, giving organizations Catalyst 9300 hardware with centralized Meraki dashboard management rather than a traditional standalone IOS XE deployment model.
Why buyers pick C9300-24U-M (plain English)
24 high-power PoE ports: Supports Cisco UPOE, making it suitable for devices that need more power than standard PoE+.
Built for higher-power endpoints: A good fit for wireless access points, PTZ cameras, phones, displays, and other devices that can require substantial PoE power.
Modular uplinks: You can choose the uplink module that best fits your network instead of being locked into fixed uplink ports.
Meraki cloud management: Centralized configuration, monitoring, firmware management, and troubleshooting through the Meraki dashboard.
Enterprise Catalyst hardware: Combines the robust Catalyst 9300 hardware platform with a simpler cloud-managed operational model.

Where it fits (and when to choose something else)
Perfect for:
- High-power wireless AP deployments
- PTZ camera networks
- IP phones and collaboration endpoints
- Digital signage
- Branch and campus access
- Organizations standardizing on Meraki cloud management
- Environments needing more power than standard PoE+
Choose something else if:
- You only need standard PoE+ → consider a C9300-24P model
- You need full traditional IOS XE management → choose the equivalent non--M Catalyst 9300 SKU
- You need 48 access ports → choose a 48-port Catalyst 9300 model
- You need multigigabit access ports → choose a C9300-24UX / C9300X model
- You do not need PoE → choose a data-only Catalyst 9300 model
TL;DR
C9300-24U-M is a Cisco Catalyst 9300 enterprise switch with 24 × 1G UPOE RJ-45 ports, modular uplinks, StackWise-480, StackPower, and Meraki cloud management — ideal for high-power enterprise access networks that want Catalyst hardware with centralized cloud-based operations.
