Field-Replaceable Units in a QFX3500 Device
Field-replaceable units (FRUs) are components that you can replace at your site. The
QFX3500 device FRUs except the management board are hot-insertable and
hot-removable: you can remove and replace them without powering off the device or
disrupting the switching function.
CAUTION: Replace a failed power supply with a blank panel or new power
supply within 1 minute of removal to prevent chassis overheating. Replace a
failed fan tray with a new fan tray within 1 minute of removal to prevent
chassis overheating.
Table 9 on page 63 lists the FRUs for the QFX3500 device and actions to take before
removing them.
