Environment

The following environmental specifications were type-tested under
controlled conditions. Hewlett-Packard maintains an active program of
auditing production products to make sure these specifications remain
true when products are retested under the same conditions. However, the
limits of these specifications do not represent the optimum for long,
trouble-free operation and specifically are not recommended for
maximum satisfaction. The recommended conditions are stated when
appropriate.

Altitude:
For continuous, trouble-free operation, the disk system should NOT be
operated at its maximum environmental limits for extended periods of
time. Operating within the recommended operating range, a less
stressful operating environment, ensures maximum reliability.
