Step 2: Mount the Drive –
Minimum Requirements
This section describes the minimum requirements to mount the drive.
Minimum Mounting Clearances
Specified vertical clearance requirements are
intended to be from the drive to the closest
object that can restrict airflow through the drive
heat sink and chassis. The drive must be
mounted in a vertical orientation as shown, and
must make full contact with the mounting
surface. Do not use standoffs or spacers. In
addition, inlet air temperature must not exceed
the product specification.
