Operational Environment

A-3

A.2.1 Thermal, Atmospheric Characteristics

The board is designed to operate in an environment defined by the
following parameters:

Temperature range: 0–55

°

C (dry bulb)

Relative humidity range: 0–90% (noncondensing)

Maximum dew point temperature: 32

°

C

A.2.2 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 and CISPR Class B limits and
is marked with the FCC Self Certification logo. It also carries the CE
mark.

A.2.3 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.3 Operational Environment

The SYM22801 is designed for use in PCI computer systems with an
ISA/EISA bracket type. The Symbios SDMS™ (SCSI Device
Management System) software operates the board, but the design of the
board does not prevent the use of other software.

A.3.1 The PCI Interface

The PCI interface operates as a 32-bit DMA bus master. The connection
is made through the edge connector J1, which provides connections on
both the front and back of the board. The signal definitions and pin
numbers conform to the PCI Local Bus Specification Revision 2.1
standard. The following tables show the signal assignments.
