2. Product Overview

Cisco Catalyst C9300X-24HX-A is a 1U rack-mount high-density enterprise access switch built on upgraded UADP 2.0 ASIC and Cisco IOS XE OS, optimized for high-power Wi-Fi6/6E enterprise AP, high-end PTZ IP surveillance camera, smart building heavy-load IoT deployment, and campus access layer aggregation. Equipped with StackWise-1T high-speed stacking and StackPower+ intelligent cross-chassis power pooling architecture, supports SD-Access fabric, zero-trust security and full advanced routing natively via built-in Network Advantage license entitlement.

Port & UPOE+ Hardware Specifications

24×Smart Rate Multi-Gigabit RJ45 downlink ports, auto-negotiate 100Mbps/1G/2.5G/5G/10GBASE-T; every port supports IEEE802.3af(15.4W)/at(30W)/bt(Type4 90W) UPOE+, maximum 90W single-port power supply for high-power endpointsCisco
Default factory pre-installed single PWR-C1-1100WAC AC power supply; baseline PoE+ budget = 735W. Optional redundant second 1100WAC modular PSU expands total available PoE budget up to 1590W; StackPower+ enables cross-stack power resource pooling across stacked switches to allocate full 90W UPOE+ to all ports simultaneously
Single rear modular uplink expansion slot compatible with C9300X dedicated uplink modules: C9300X-NM-8X(8×10G SFP+), C9300X-NM-4Y(4×25G SFP28), C9300X-NM-2Q(2×40G QSFP+), C9300X-NM-1C(1×100G QSFP28), flexible uplink bandwidth from 1Gbps up to 100GbpsCisco
