Patent ID: 7316606

Claim:
A system comprising: a frame comprising at least one chassis; an airflow path through said chassis including an intake region and an exhaust region; at least one circuit board configured to be coupled to said at least one chassis, said at least one circuit board including at least one heat generating component; a primary cooling system including at least one fan configured to provide a first airflow through said airflow path to convectively cool said at least one heat generating component of said at least one circuit board; a selectively deployable fan assembly comprising at least one fan; and a drive system configured to move said at least one fan assembly between a stowed configuration wherein said fan assembly is at least partially retracted into and removed from said airflow path to permit airflow through said airflow path and a deployed configuration wherein said fan assembly is positioned adjacent to said intake region and is configured to provide a second airflow through said airflow path to convectively cool said at least one heat generating component of said at least one circuit board.
