The switch runs the industry-leading Cisco® NX-OS Software operating system, providing customers with comprehensive features and functions that are widely deployed globally. The Cisco Nexus 3548 contains no physical layer (PHY) chips, allowing low latency and low power consumption. This switch supports both forward and reversed airflow schemes and both AC and DC power inputs.

The Cisco Nexus 3548 has the following hardware configuration:

  • 48 fixed Enhanced Small Form-Factor Pluggable (SFP+) ports (1 Gbps or 10 Gbps)
  • Dual redundant, hot-swappable power supplies
  • Four individual, redundant, hot-swappable fans
  • One 1-PPS timing port, with the RF1.0/2.3 QuickConnect connector type
  • Two 10/100/1000 management ports
  • One RS-232 serial console port
  • One USB port
  • Locator LED
  • Locator LED button

Support for both forward (port-side exhaust) and reversed (port-side intake) airflow schemes is available. ‘Portside exhaust’ scheme would be used when the cold air flows in through the side having the fans (facing the cold aisle) and exhausts out of the side having the ports (facing the hot aisle). ‘Port-side intake’ scheme would be used when the air flows in through the ports (facing the cold aisle) and leaves through the side having the fans (facing the hot aisle).
