C9500-48Y4C-A Description
C9500-48Y4C-A is a Cisco Catalyst 9500 High Performance enterprise core and aggregation switch built for organizations that need large-scale 25G access density and native 100G backbone connectivity in a fixed 1RU platform.
With 48 multi-rate 1G / 10G / 25G SFP28 ports and 4 fixed 40G / 100G QSFP28 uplinks, this model is commonly selected for campus core refresh, collapsed-core designs, data-intensive enterprise networks, high-density distribution layers, and large server aggregation environments.
For buyers comparing long-term infrastructure ROI, C9500-48Y4C-A is often preferred over legacy 10G platforms because it enables immediate reuse of 10G optics while creating a clear path toward 25G edge migration and 100G core growth.

Selection Guide
1. Choose C9500-48Y4C-A for high-density enterprise growth
If many 25G ports are needed now or soon, start with 48-port density.
2. Choose C9500-48Y4C-E if software cost matters more
Same hardware platform with lower feature tier.
3. Choose C9500-24Y4C-A when 24 ports are enough
Good option for smaller core or aggregation environments.
4. Choose C9600 if modular expansion is required
If future line card growth is critical, modular chassis may be better.
