Warning:
If a lithium battery is installed in your system as a soldered part, only SGI

Octane III Cluster Server Cooling
The SGI Octane III server is cooled using 12 fans (six on the front and six on the rear). The six
front fans push air into the enclosure while the rear six fans pull it out the back.
The system fan assemblies are located behind the front and rear panels on the enclosure.
Figure 1-5 on page 12 illustrates the fan locations on the system.
