3.3.1 Electrical Characteristics
lists the maximum power requirements for standard Ultra320
SCSI to PCI-X host adapter boards, including SCSI TERMPWR, under
normal operation.
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
