An HP AB312-3405A air baffle is provided to improve air flow over HP AM225A, AM232A, and

Installing the air baffle
To install the air baffle, follow these steps:

2. Determine the correct orientation of the air baffle. The thicker end tab must be installed between
the PCI bay’s blue lockers; the thinner end tab must be installed facing the fan bay.
