​​Core Hardware and Performance Specifications​​

The Cisco Catalyst C9300LM-24U-4Y-1A is a ​​24-port Layer 3 stackable switch​​ designed for high-density, high-speed enterprise networks. It features ​​24x 1G/10G Multi-Gigabit RJ45 ports​​ (supporting up to 5Gbps via NBASE-T) and ​​4x 25G SFP28 uplinks​​, enabling seamless integration with high-performance servers and storage systems. Built on Cisco’s ​​DNA architecture​​, it supports ​​SD-Access​​ for automated policy enforcement and ​​Cisco Umbrella​​ for cloud-delivered security.

Key specs include ​​200 Gbps switching capacity​​ and ​​StackWise-320 technology​​, allowing up to eight switches to operate as a single logical unit. The ​​1A​​ designation indicates a ​​front-to-back airflow design​​, optimized for hot/cold aisle containment in data centers.

​​Target Deployment Scenarios​​

This switch excels in ​​edge computing environments​​, ​​mid-sized data centers​​, and ​​enterprise branch offices​​ requiring high-speed uplinks in compact form factors. Its ​​energy-efficient design​​ reduces power consumption by up to 30% compared to traditional switches, while ​​PoE+ support​​ (on 16 ports) powers devices like wireless APs and IoT sensors.

​​Resolving Critical User Concerns​​

• ​​Q: How do the 25G uplinks benefit bandwidth-intensive applications?​​
  The ​​4x 25G SFP28 ports​​ provide low-latency connectivity for applications like AI/ML workloads, video analytics, and real-time databases, eliminating bottlenecks in data aggregation.

• ​​Q: Can it scale without disrupting operations?​​
  Yes—​​StackWise-320​​ enables non-disruptive stacking, allowing IT teams to add switches dynamically without downtime.

• ​​Q: Does it support advanced security for remote sites?​​
  Integrated ​​Cisco ISE​​ and ​​MACsec encryption​​ enforce zero-trust policies, securing traffic across distributed networks.

​​Licensing and Procurement Options​​
