Altitude
Table 8 lists the acceptable altitudes for operating, storing, and shipping the DCS3700.
Table 8. DCS3700 altitude ranges
Environment Altitude
Operating 30.5 m (100 ft.) below sea level to 3000 m (9,840 ft) above
sea level
Storage 30.5 m (100 ft.) below sea level to 3000 m (9,840 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 13 shows the intended airflow for the DCS3700. 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.
Table 9 lists the KVA, watts, and Btu calculations. These values assume the power supplies have a 88
percent efficiency and a power factor of 0.99. These tabulated power and heat dissipation values are
typical for the storage subsystem. Maximum configuration units are typically operated at higher data
rates, have larger random access memory (RAM) capacities, or have different host interface boards.

Shock and vibration requirements
Operational shock and operational vibration requirements are shown in this section.
Operational Shock: The DCS3700 will be able to withstand the following shock. Subjecting the
equipment to a single shock pulse with the following characteristics will simulate this level of shock:
