Table 13 lists the KVA, watts, and Btu calculations for the DS5100 and DS5300.
These values assume the power supplies have a 73 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 DS5100 and DS5300 withstands the following shock.
Subjecting the equipment to a single shock pulse with the following characteristics
will simulate this level of shock:
v Velocity change = 20 inches per second
v Wave form = Triangular, 10g @3.75 ms
Operational Vibration (Random): While in its normal operating position, the
DS5100 and DS5300 continues operating when subjected to a random vibration
test using the criteria shown in Table 14 on page 29. This test uses a dwell time of
15 minutes at any frequency where vigorous or resonant excitation occurs.
