3.3.2 Thermal and Atmospheric Characteristics
The thermal and atmospheric characteristics for all Ultra320 SCSI Host Adapter boards are:
• Temperature range: 0 ° C to 55 ° C (dry bulb)
•Relative humidity range: 5% to 90% noncondensing
•Maximum dew point temperature: 32 ° C
•Airflow must be sufficient to keep the LSI53C1020 and LSI53C1030 heat sink temperature below 80 ° C
The following parameters define the storage and transit environment for the Ultra320 SCSI Host Adapter boards:
• Temperature range: 40 ° C to 105 ° C (dry bulb)
•Relative humidity range: 5% to 90% noncondensing
