Removing a Fan Tray from an EX4500 Switch
An EX4500 switch has a single fan tray. The fan tray is a hot-removable and hot-insertable

is running without turning off power to the switch or disrupting switching functions.
CAUTION:
Do not remove the fan tray unless you have a replacement fan
tray available.
