QFX5140 Power System

The QFX5140 power system includes AC or DC power supply units (PSUs) with related power cords and cables. The PSUs operate within certain ranges and are equipped with status indicator LEDs.

The QFX5140 AC and DC models use two 1600-W PSUs with support for 1+1 redundancy. The PSUs are preinstalled at the factory. The PSUs in the QFX5140 are hot-insertable and hot-removable field-replaceable units (FRUs). If one PSU fails, you can replace it without powering off or disrupting the routing function. The other PSU balances the electrical load without interruption. A fan in each PSU provides cooling. The PSUs are located at the rear of the QFX5140.

CAUTION:

Avoid mixing:

  • AC and DC PSUs in the same chassis.

  • PSUs with different ratings in the same chassis.

  • PSUs with different airflow directions in the same chassis.

  • PSUs and fan modules with different airflow directions in the same chassis.

The maximum and typical power consumption of the system depends on the type of power supply.

Note:

Maximum power consumption is measured at 40°C ambient temperature with SR optics, and at 100% load with IMIX traffic. Typical power consumption is measured at 25°C ambient temperature with DACs, and at 50% load with IMIX traffic, excluding transceivers. Power consumption is subject to operating conditions and unit-to-unit variations.
