3.3.2 Thermal and Atmospheric Characteristics

The thermal and atmospheric characteristics for all Ultra320 SCSI host adapters 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

•host adapters using the LSI53C1020A do not require a heat sink

The following parameters define the storage and transit environment for the Ultra320 SCSI host adapters:

• temperature range: − 40 ° C to 105 ° C (dry bulb)

•relative humidity range: 5% to 90% noncondensing

3.3.3Safety Characteristics

All Ultra320 SCSI host adapters meet or exceed the requirements of UL flammability rating 94 V0. Each bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. Because these boards are installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.
