All dimensions are given in mm and inches.
The LSIU40SE maximum power requirements, including SCSI
TERMPWR, under normal operation are as follows:
+5 V DC 5%
+12 V 0.6 V
.
+3.3 V 0 3 V
Under abnormal conditions such as a short on SCSI TERMPWR, + 5 V
current may be higher. At temperatures of at least 25
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.
