Virtual Chassis Fabric Overview QFX5110 Hardware Models The QFX5110 switches have 32 or 48 port configurations. Both switches are available with either AC or DC power supply and with either airflow-in or airflow-out cooling. All models of the QFX5110, except the QFX5110-32Q_CHAS, ship with two power supplies and five fans installed by default.
Page 28: Functionality
Cooling system—All QFX5110 switches, except the QFX5110-32Q-CHAS, ship with five fan modules installed. If a fan module fails and is unable to keep the QFX5110 within the desired temperature thresholds, chassis alarms occur and the QFX5110 can shut down.
