Fan Modules
The PowerEdge C8000 server enclosure includes three pairs of hot-swappable
fan modules that provide the system with redundant cooling source. Each fan
module contains two separate cooling fans. All three fan modules must be
installed at all times to ensure proper cooling.
NOTE: If a fan module is removed from the enclosure, all sleds in the enclosure will
be throttled until the fan module is replaced. If two fan modules fail at the same time
and are not replaced within 90 seconds, the enclosure will shutdown automatically.
For more information on troubleshooting a fan module(s), see the "Troubleshooting
Enclosure Fan Modules" on page 257.

CAUTION: To ensure proper airflow in the system, if a fan module is removed it
should be immediately replaced with another module.
