Fan Modules
The fan modules in EX4600 switches are hot-insertable and hot-removable eld-replaceable units
(FRUs). These fan modules are designed for one of the two available airow direcons airow in (AIR IN)
or airow out (AIR IN)) and are the same fan modules used in the QFX5100 switches. Some modules are
also color-coded for the indicaon of the airow direcon. The fan modules are installed in the fan
module slots on the FRU end of the switch, next to the power supplies. The fan module slots are
numbered 0 through 4 from le to right. Each slot has a fan icon next to it.
