SMBus Electrical Parameters
The SMBus interface operates only when 3.3V_AUX is supplied to the drive. When 3.3V_AUX and 12V are supplied to the
drive, the SMBus interface functions fully. When only 3.3V_AUX is supplied to the drive (12V off ), VPD data remains
accessible over the SMBus interface, but other functions are unavailable. No specific sequencing is needed for the 12V
and 3.3V_AUX input voltages.

Storage
You can store the drive for a maximum of 180 days in the original unopened Seagate shipping package or 60 days,
unpackaged, in the defined non-operating limits (See
Table 8, Temperature and Humidity
). You can extend storage to 1
year packaged or unpackaged under optimal environmental conditions (<40°C, <40% relative humidity non-
condensing, and non-corrosive environment).
NOTE
Specification does not cover connection issues that might result from testing at this
level.
Operating shock:
The drive, as installed for normal operation, operates
error free while subjected to intermittent shock not exceeding the
specification. Shock may be applied in the X, Y, or Z-axis. Shock is not to be
repeated more than once every 2 seconds.
Non-Operating shock:
The limits of non-operating shock apply to all
conditions of handling and transportation. This includes isolated drive and
integrated drives. Shock may be applied in the X, Y, or Z-axis.
