A.1.3 Thermal, Atmospheric Characteristics
The board is designed to operate in an environment, which is defined by
the following parameters:
Temperature range: 0
°
C to 55
°
C (dry bulb)
Relative humidity range: 5% to 90% noncondensing
Maximum dew point temperature: 32
°
C
The board is designed for a storage and transit environment, which is
defined by the following parameters:
Temperature range:
45
°
C to + 105
°
C (dry bulb)
Relative humidity range: 5% to 90% noncondensing
A.1.4 Electromagnetic Compliance
This board is tested to and meets class B regulatory requirements for
United States, Canadian, European, Japanese, and Australian markets
and carries the appropriate markings (FCC, CE, VCCI, C-Tick) indicating
such compliance.
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 SYM22902 is designed for use in PCI computer systems with either
a standard ISA/EISA or LPPCI bracket type. The SDMS software
operates the board, but the design of the board does not prevent the use
of other software. An on-board Flash memory device is provided to allow
BIOS code and open boot code support through PCI and a serial
EEPROM for each channel.
