System components
To locate the fan modules and their LEDs
1.

2.
Check the attention LED on each fan module to determine whether the fan module is working properly.
An amber LED light indicates a fan module failure:
3.
Hot swap the fan module as required.
The system fails to start if the controller does not detect the presence of the associated fan module. You must
replace a fan module within two minutes of removing it from the chassis to minimize disruption to the system's
airflow. If the fan module is not replaced within two minutes, the system shuts down to avoid overheating. For
information on replacing fan modules, see
“Hot-swapping controller fan modules” on page 67
.
Fan redundancy policy
The AltaVault system fan redundancy policy enables the system to continue operating with a single fan failure (one
fan failure in any one fan module). Each fan module has two fans.
The following events indicate fan failure:
The fans speed has fallen below the critical low threshold.
One or both fans in the fan module have stopped spinning.
