The fan tray operates as a single unit. If an individual fan in the tray fails, you must replace the enre fan
tray. However, the fan tray connues to operate indenitely and provides sucient cooling even when a
single fan rotor fails. The fan tray operates indenitely provided that the room temperature is within the
operang range.
If you want to replace an exisng fan tray while the router is running, remove only one fan tray. The
router connues to operate for a limited me with a single operang fan tray without triggering a
thermal alarm.
CAUTION: To avoid triggering a thermal alarm, remove only one fan tray while the
router is operang.
