Cooling system—All models of the QFX10002 have three fan modules. Each fan module
is a redundant unit containing two fans. If a fan module fails and is unable to keep the
QFX10002 within the desired temperature thresholds, chassis alarms occur and the
QFX10002 device might shut down.
Field-replaceable units (FRUs) are components that you can replace at your site. The
QFX10002 FRUs are hot-removable and hot-insertable: you can remove and replace
them without powering off the switch or disrupting the switching function.
CAUTION: Replace a failed fan module with a new fan module within one
minute of removal to prevent chassis overheating.
Table 7 on page 26 lists the FRUs for the QFX10002-72Q and actions to take before
removing them.
