QFX5200 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5200 device
FRUs are hot-insertable and hot-removable: you can remove and replace one of them without powering
off the switch or disrupting the switching function.
CAUTION: Replace a failed power supply with a new power supply within one minute
of removal to prevent chassis overheating. The switch continues to operate with only
one power supply running. Replace a failed fan module with a new fan module within
one minute of removal to prevent chassis overheating. Do not operate the switch with
missing FRUs for longer than one minute.
Table 2 on page 8 lists the FRUs for the QFX5200 device and actions to take before removing them.
