3.3.4 Electrical Characteristics
This subsection provides the power requirements for the MegaRAID 320
Storage Adapters.
Table 3.10 lists the maximum power requirements,
which include SCSI TERMPWR, under normal operation.
3.3.5 Thermal and Atmospheric Characteristics
For all MegaRAID 320 Storage Adapters, the thermal and atmospheric
characteristics are
•
relative humidity range: 5% to 90% noncondensing
•
maximum dew point temperature: 32
° C
•
airflow must be at least 300 linear feet per minute (LFPM) to keep
the LSI53C1020 and LSI53C1030 heat sink temperature below 80
° C
The following parameters define the storage and transit environment for
the MegaRAID 320 Storage Adapter
•
temperature range:
−40 ° C to +105 ° C (dry bulb)
•
relative humidity range: 5% to 90% noncondensing
