A-2 Technical Specifications
Figure A.1 LSIU40HVD Mechanical Drawing
A.1.2 Electrical Characteristics
The LSIU40HVD maximum power requirements, including SCSI
TERMPWR, under normal operation are as shown in
Table A.1 .
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 opens.
The PCI PRSNT1/ and PRSNT2/ pins are set to indicate a 15 W
maximum configuration.
