Operational Environment A-3
The PCI PRSNT1/ and PRSNT2/ pins are set to indicate a 7.5 W
maximum configuration.
A.1.3 Thermal, Atmospheric Characteristics
The board is designed to operate in an environment defined by the
following parameters:
• Temperature range: 0 °Cto55°C (dry bulb)
• Relative humidity range: 5% to 90% noncondensing
• Maximum dew point temperature: 32 °C
• Storage Temperature: − 45 °Cto+105°C (dry bulb)
A.1.4 Electromagnetic Compliance
The board is designed and implemented to minimize electromagnetic
emissions, susceptibility, and the effects of electromagnetic discharge.
The board meets the requirements of FCC Class B and CISPR 22 limits
and is marked with the FCC Class B Declaration of Conformity Symbol.
It also carries the CE mark.
A.1.5 Safety Characteristics
The bare board meets or exceeds the requirements of UL flammability
rating 94 V0. The bare board is also marked with the supplier’s name or
trademark, type, and UL flammability rating. Since this board is installed
in a PCI bus slot, all voltages are below the SELV 42.4 V limit.
A.2 Operational Environment
The SYM8953U host adapter is designed for use in PCI computer
systems. SDMS operates the board, but the design of the board does
not prevent the use of other software.
