Replacing a 7x20 Fan Module
![Caution Caution](graphics/caution.gif) | Caution -
Operating a controller for over 60 seconds with fans removed reduces the
effectiveness of the cooling system. For this reason, the replacement fan
should be unpacked in advance and ready to insert into the controller
chassis as soon as the faulted fan is removed.
|
Fan modules are hot-swappable and can be removed and installed while the
storage controller is running without affecting other hardware
capabilities.
7120 or 7320: The fan modules and status
indicators are hidden under a fan door in the 7120 and 7320 storage controllers.
Components may differ slightly between the 7120 and 7320, however service
procedures for each are identical. The illustration shows the 7320
controller.

The storage controller might overheat and shut down if the door is left
open for more than 60 seconds.
