Cisco C9300-48H-A — Catalyst 9300 48-Port UPOE+ Switch with Modular Uplinks and Network Advantage
What it is
C9300-48H-A is a Cisco Catalyst 9300 Series enterprise access switch designed for campus and branch networks that need 48 × 1 Gigabit Ethernet copper ports with UPOE+, modular uplinks, high stacking bandwidth, and advanced Layer 3 capabilities.
It provides 48 × 10/100/1000Base-T RJ-45 UPOE+ ports, supports up to 90W per port on compatible powered devices, and includes the Network Advantage software tier.
Why buyers pick C9300-48H-A (plain English)
48 high-power PoE ports: All 48 copper ports support Cisco UPOE+, making the switch suitable for high-power access points, PTZ cameras, displays, collaboration devices, and other demanding endpoints.
Up to 90W per port: UPOE+ provides significantly more power than standard PoE+ for devices that need more than 30W.
822W PoE budget with standard PSU: With the standard 1100W AC power supply, the switch provides up to 822W of available PoE power.
Modular uplinks: The uplink module is selected separately, so you can choose the fiber or high-speed connectivity that best fits your network.
Network Advantage licensing: Provides broader Layer 3 routing, segmentation, resiliency, and enterprise capabilities than Network Essentials.

Choose something else if:
- You only need Network Essentials → choose C9300-48H-E
- You only need standard PoE+ → consider C9300-48P-A
- You need multigigabit access speeds → choose C9300-48UN-A, C9300-48UXM-A, or a Catalyst 9300X model
- You do not need PoE → choose a data-only Catalyst 9300 model
- You need fixed uplinks → consider a Catalyst 9300L model
TL;DR
C9300-48H-A is a Cisco Catalyst 9300 enterprise switch with 48 × 1G UPOE+ RJ-45 ports, up to 90W per port, an 822W PoE budget with the standard 1100W PSU, modular uplinks, StackWise-480, StackPower, Cisco IOS XE, and Network Advantage licensing — ideal for high-density, high-power enterprise access networks.
