• Forward and reversed airflow schemes
• Forward airflow: Port-side exhaust (air enters through fan-tray and power supplies and exits
through ports)
• Reversed airflow: Port-side intake (air enters through ports and exits through fan tray and
power supplies)
• Single fan tray with redundant fans
• Hot swappable (must swap within 1 minute)
