Note: Varium C1100 compute adaptor is designed to be installed into a data center server, where
controlled air flow provides direct cooling. If the cooling enclosure is removed from the adaptor and the
adaptor is powered-up, external fan cooling airflow MUST be applied to prevent over-temperature shut-
down and possible damage to the adaptor electronics. Removing the cooling enclosure voids the board
warranty.
