A.1 Environmental Stabilization
To ensure proper operation of Digital storage devices, the StorageWorks building
block (SBB) temperature must be within 18–29°C (65–85°F). Table A–1 specifies
the time required to thermally stabilize SBBs based on the ambient shipping
temperature.

CAUTION
Always stabilize storage devices in the operating environment prior to
installation or operation. Otherwise, the media or associated electronics
may be damaged when power is applied to the unit.
If condensation
is visible
on the outside of the storage device:
Stabilize the device and the SBB in the operating environment for 6 hours or
until the condensation is no longer visible, whichever is longer. Do not insert
the storage device into the shelf until it is fully stabilized.
If condensation
is not visible
on the outside of the storage device:
Thermally stabilize the device for the amount of time specified in Table A–1.
