Extending the hard drive drawer
1. Ensure that all I/O bays contain either an I/O module or an I/O blank. The hard drive drawer
does not open if I/O bays are empty.
2. Ensure that the I/O modules or I/O blanks are fully seated and their handles are in the locked
position. The hard drive drawer does not open if I/O modules or I/O blanks are not fully
seated with their handles in the locked position.
WARNING!
To reduce the risk of personal injury or damage to the equipment:
• Do not extend the hard drive drawers beyond the supporting surface when the unit is
not installed in a rack.
• Ensure that only one hard drive drawer is extended at a time.
3. Extend the hard drive drawer.
WARNING! Pinch hazard—Keep hands out of front and rear of chassis when closing hard
drive drawers.
CAUTION: To prevent improper cooling and thermal damage, do not operate the D6020
for more than 10 minutes with the drawer open. If the drawer is extended more than 10
minutes while the system is powered on, the system could shut down unexpectantly even
though internal fans maximize their speed in attempt to cool down the system.
