3-8 Ultra320 SCSI Host Adapter Characteristics

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

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.
