Relative Humidity; Effective Altitude (Sea Level); Shock And Vibration - Seagate ST400FM0323 Product Manual

6.3.2

Relative humidity

The values below assume that no condensation on the drive occurs.
a. Operating
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
b. Non-operating
5% to 95% non-condensing relative humidity.
6.3.3

Effective altitude (sea level)

a. Operating
–1000 to +10,000 feet (–304.8 to +3048 meters)
b. Non-operating
–1000 to +40,000 feet (–304.8 to +12,192 meters)
6.3.4

Shock and vibration

Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an
enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure resulting in
drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize
drive movement.
The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods
shown in Figure 18, and in accordance with the restrictions of Section 10.3.
6.3.4.1 Shock
a. Operating—normal
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:
• 1000 Gs at a maximum duration of 0.5ms (half sinewave)
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.
Note.
This specification does not cover connection issues that may result from testing at this level.
b. Non-operating
The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes both isolated drives
and integrated drives.
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device damage or perfor-
mance degradation.
• 1000 Gs at a maximum duration of 0.5ms (half sinewave)
Shock may be applied in the X, Y, or Z axis.
c. Packaged
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM standards. Volume fin-
ished drives will be shipped from Seagate factories on pallets to minimize freight costs and ease material handling. Seagate fin-
ished drive bulk packs may be shipped individually. For less than full shipments, instructions are printed on the bulk pack carton
for minimum drive quantities and proper drive placement.
