6 Drive mounting
MSST5/10-S drives can be mounted on the wide or narrow side of the chassis using #6 screws. If
possible, the drive should be securely fastened to a smooth, flat metal surface that will help con-
duct heat away from the chassis. If this is not possible, forced airflow from a fan may be required
to prevent the drive from overheating.
▪ Never use the drive in a space where there is no air flow or where the ambient temperature
exceeds 50ºC (120ºF).
▪ Never put the drive where it can get wet.
▪ Never allow metal or otherwise conductive particles near the drive.
