Cisco Catalyst C9300X-24T-E, 1RU stackable Layer3 Gigabit copper aggregation switch, 24-port 10/100/1000BASE-T RJ45 data-only downlinks with 1 modular high-speed uplink slot, pre-installed permanent Network Essentials IOS XE license, StackWise-1T 1Tbps stacking support, factory single 350W AC power supply, managed via local CLI and basic Cisco Catalyst Center for entry-level campus workstation aggregation and branch office wired networks with limited routing demands.

3. Complete Product Overview Paragraph

The Cisco Catalyst C9300X-24T-E is a fixed-form-factor all-copper stackable Layer 3 enterprise switch within the Catalyst 9300X series, designed for cost-effective Gigabit desktop aggregation, small campus distribution closets and entry-level branch wired environments without PoE endpoints. It features 24 standard Gigabit RJ45 copper ports plus one dedicated hot-swappable C9300X-NM uplink slot for flexible 10G/25G/40G/100G fiber uplink expansion. Powered by UADP 2.0sec ASIC and running native IOS XE with permanent Network Essentials license, this chassis delivers foundational switching and constrained Layer 3 functionality, while advanced enterprise capabilities such as full BGP routing, SD-Access fabric integration, TrustSec zero-trust segmentation and Encrypted Traffic Analytics are unavailable. It supports StackWise-1T stacking to combine up to 8 identical C9300X switches into a single logical stack with 1 Tbps aggregate stacking bandwidth and sub-50ms stack failover convergence. Dual redundant AC power slots and field-replaceable variable-speed fans remove single points of hardware failure. Managed locally via console CLI, SNMPv3 or limited Catalyst Center integration rather than Meraki cloud, it includes basic zero-touch provisioning and sampled traffic monitoring suitable for mid-size copper-heavy networks without advanced security or routing requirements.

8. IOS XE License Tier Comparison for C9300X On-Prem Switches

Network Essentials (-E, Base Tier, This Unit)

Complete Layer 2 toolkit, capped OSPF route entries (1,000 max), baseline port security, sampled flow monitoring and basic zero-touch provisioning. Advanced routing, micro-segmentation, ETA and 256-bit MACsec are disabled.
Network Advantage (-A, Full Premium Tier)

Unlimited routing scale, TrustSec SGT segmentation, full unsampled telemetry, ETA analytics, full SD-Access integration and 256-bit MACsec encryption.

Key difference vs Meraki C9300X-M cloud models: C9300X-E/-A use permanent on-prem IOS XE perpetual licenses managed via CLI/Catalyst Center; C9300X-M requires renewable Meraki cloud subscriptions and Meraki Dashboard control. All stack members must match identical license tiers for full interoperability.
