3.3.2 Thermal and Atmospheric Characteristics
The thermal and atmospheric characteristics for all Ultra320 SCSI host
adapters are:
• temperature range: 0 °Cto55°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
3.3.3 Safety 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.
