Cooling system fans
The Altos G900 server accommodates six hot-swap fan modules.
Caution! Don't remove a fan module while the server is powered on unless you have a replacement unit available. Once you remove a fan module from the system, replace it within five minutes. Vacant spaces alter airflow patterns in the server system and can cause overheating and damage to system components.
Checking a fan status indicator
Fault LED indicators for each fan module are located on the fan board. The indicators are visible through a cutout in the housing of each module.
