Cisco C9300-48P-A Access Campus Switch
The Cisco Catalyst 9300-48P-A is a 1 RU, fixed-access enterprise campus switch built for mission-critical U.S. networks—from Silicon Valley innovation labs to Wall Street trading floors.
As part of the Catalyst 9300 family, it delivers 48 auto-sensing 10/100/1000 RJ-45 PoE+ ports with a default 715 W platinum-rated AC power supply (optional 1,100 W PSU for expanded PoE), hot-swappable field-replaceable fans, and modular uplink flexibility via Cisco network modules.
Running Cisco IOS XE with the Network Advantage license, it offers advanced Layer 2/3 services, enterprise-grade security, and seamless integration with Cisco DNA Center or Meraki cloud monitoring.
