C9300-24U-A Switch

1. Product Overview & Suffix Definition

Cisco Catalyst C9300-24U-A is high-power stackable Layer3 enterprise UPOE access switch within Catalyst 9300 IBN (Intent-Based Networking) portfolio, powered by UADP 2.0 ASIC and Cisco IOS XE OS, optimized for high-power IoT terminals, digital signage, Wi-Fi 6 AP, VDI thin-client deployment.

• U: 24×10/100/1000BASE-T RJ45 ports with Cisco UPOE (Universal PoE, up to 60W per single port, IEEE802.3bt compatible); far higher power output than standard IEEE802.3at PoE+ (30W).
• A: Preinstalled perpetual top-tier Network Advantage permanent license, full complete routing & advanced security feature set (full BGP, MPLS, MACsec, ETA, TrustSec unavailable on -E Essentials model).
• Supports StackWise-480 stacking (max 8 switches per logical stack, total 480Gbps stacking bandwidth) and StackPower cross-chassis pooled power sharing among stacked devices.

2. Port Configuration

• 24 fixed auto-sensing 10/100/1000BASE-T RJ45 downlink ports with full UPOE capability; factory default single 1100W AC modular PSU delivers total UPOE budget:830W, expandable PoE capacity by installing redundant secondary AC/HVDC power supply.
• 1 rear hot-swappable modular network module slot, compatible with C9300-NM-4G / C9300-NM-8X / C9300-NM-2Q / C9300-NM-4M modules for flexible 1G/10G/25G/40G fiber uplink expansionCisco.
• RJ45 serial console + Mini-USB out-of-band local management port for emergency maintenance access.
• Exclusive rear dedicated StackWise-480 stacking interfaces for inter-switch physical stacking cablingCisco.

3. Core Hardware Performance Parameters

4. Power & Thermal Specifications

• Factory preinstalled single hot-swappable modular 1100W AC power supply (PWR-C1-1100WAC), vacant second PSU slot supports redundant power upgrade for power redundancy & extra UPOE power budget expansion.
• Universal input AC range:100–240V 50/60Hz; fully compliant with StackPower dynamic cross-stack power resource allocation.
• Cooling setup:3 field-replaceable variable-speed hot-swappable fan modules with N+1 redundant thermal regulation, auto-adjust fan speed for energy saving under different ambient temperature.
• Native Perpetual PoE & Fast PoE function to sustain continuous power supply for critical high-power UPOE endpoints during transient power dip.

5. Mechanical & Installation Spec

• Form Factor: Standard 1RU 19-inch EIA rack mount chassis
• Overall Dimension: H:44mm × W:445mm × D:445mm / 1.73in ×17.5in ×17.5in
• Approximate net weight: ~7.42KG (16.33 lbs)
• Supported deployment: Standard 19-inch cabinet rack installation or optional desktop flat placement.

6. Software Feature Set (Full Network Advantage Top-Tier License, core advantage vs -E/-M variants)
