Condition
Relative humidity (no
condensation)
Notes:
1. The non-operating environment must not exceed the operating environment
limits for longer than 60 days.
2. The storage environment must not exceed the operating environment limits for
longer than one year.
3. Substantial deviations from the suggested operating range, in either direction, if
sustained for extended periods of time, will expose the unit to greater risk of
failure from external causes.

Altitude

Table 12 lists the acceptable altitudes for operating, storing, and shipping the
DS5100 and DS5300.

Airflow and heat dissipation

Figure 11 on page 28 shows the intended airflow for a DS5100 and DS5300. Allow
at least 30 inches in front of the storage subsystem and at least 24 inches behind
the storage subsystem for service clearance, proper ventilation, and heat
dissipation.
