Installing a Power Supply in a QFX3600 or QFX3600-I Device

 

The QFX3600 and QFX3600-I devices are shipped from the factory with two 650 W power supplies pre-installed. Each power supply is a hot-removable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power supplies on the rear panel without powering off the device or disrupting the switching function.

Before you install a power supply in a QFX3600 device, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

Ensure that you have the following parts and tools available to install a power supply in a QFX3600 device:

  • ESD grounding strap

To install a power supply in a QFX3600 device (see Figure 1):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Taking care not to touch power supply components, pins, leads, or solder connections, remove the power supply from its bag.
  3. Using both hands, place the power supply in the power supply slot on the rear panel of the device and slide it in until it is fully seated and the locking lever slides into place.
