Table 11. Temperature and humidity requirements (continued)
Condition
Parameter
Requirement
Relative humidity (no
condensation)
Operating range
20% to 80%
Storage range
10% to 93%
Transit range
5% to 95%
Maximum dew point
26° C (79° F)
Maximum gradient
10% per hour
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.
Table 12. DS5100 and DS5300 altitude ranges
Environment
Altitude
Operating
30.5 m (100 ft.) below sea level to 3048 m
(10,000 ft.) above sea level
Storage
30.5 m (100 ft.) below sea level to 3048 m
(10,000 ft.) above sea level
Transit
30.5 m (100 ft.) below sea level to 12,000 m
(40,000 ft.) above sea level
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.
