Environmental recovery
If the system exceeds the maximum ambient temperature by approximately 10°C
(18°F), the SP assemblies in the system begin an orderly shutdown that saves cached
data, and then shut themselves down. Link control cards (LCCs) in each DAE in the
system power down disks but remain powered on.
If the system detects that the temperature has dropped to an acceptable level, it
restores power to the DPEs and the LCCs restore power to their disks.
Shipping and storage requirements
Systems and components must not experience changes in temperature and humidity
that are likely to cause condensation to form on or in that system or component. Do
not exceed the shipping and storage temperature gradient of 45°F/hr (25°C/hr).
Table 13 Shipping and storage requirements
Requirement Description
Ambient temperature -40° F to 149°F (-40°C to 65°C)
Temperature gradient 45°F/hr (25°C/hr)
Relative humidity 10% to 90% noncondensing
Elevation -50 to 35,000 ft (-16 to 10,600 m)
Storage time (unpowered) Recommendation Do not exceed 6 consecutive months of
unpowered storage.
Shock and Vibration
Products have been tested to withstand the shock and random vibration levels. The
levels apply to all three axes and should be measured with an accelerometer on the
equipment enclosures within the cabinet and shall not exceed:
Platform condition
Response measurement level
Non operational shock 10 G’s, 7 ms duration
Operational shock 3 G’s, 11 ms duration
Non operational random vibration 0.40 Grms, 5–500 Hz, 30 minutes
Operational random vibration 0.21 Grms, 5–500 Hz, 10 minutes
