Physical Environment A-3
Under abnormal conditions, such as a short on SCSI TERMPWR, +5 V
current may be higher. At temperatures of at least 25
°
C a current of
4 A is sustained no longer than 30 seconds before the self-resetting
TERMPWR short circuit protection device (F1) opens.
The PCI PRSNT1/ and PRSNT2/ pins are set to indicate a 15 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
°
C to 55
°
C (dry bulb)
•
Relative humidity range: 5% to 90% noncondensing
•
Maximum dew point temperature: 32
°
C
The LSIU160 is design for a storage and transit environment defined by
the following parameters:
•
Storage Temperature:
−
45
°
C to 105
°
C (dry bulb)
•
Relative Humidity Range: 5% to 90% noncondensing
A.1.4 Electromagnetic Compliance
The board is designed and implemented to minimize electromagnetic
emissions, susceptibility, and the effects of electromagnetic discharge.
The board carries the CE mark, VCCI, Canada mark, and meets the
requirements of FCC Class B. The board is marked with the FCC
self-certification logo.
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.
