2.2.4 Power Connectors for Peripherals (CN1 and CN2)
The CN1 and CN2 connectors provide power to the peripherals, such as hard disk drives
or floppy disk drives.
2.2.5 V I/O Voltage Selection (T1 ~ T3 )
This jumper is used to select the V I/O voltage. MIB- 3081A allows V I/O to be set to
either 5 V or 3.3 V. Since the MIB- 3081A default is configured for use with 5 V
CompactPCI boards (blue k eyed connectors), once the jumper is set to 3.3 V, the
CompactPCI keys must be changed to 3.3 V at the same time (as yellow keyed
connectors).
2.2.6 Power Switch ( CN4)
This connector provides power on/off control of the ATX power supply or the plug- in
power module. If the CompactPCI chassis provides a 2-pin power switch cord, connect
this cord to the CN4 connector and users can control the power on/off by the power
switch. Or users can directly short this connector by a jumper and control the power
on/off by the ATX power supply switch.
2.2.7 LED Status Connector ( JP1)
This connector provides digital outputs for the alarm module (MIC- 3924) to the chassis
front panel notification used. Three alarm LED (red) and one power status LED (green)
is included for Fan_fail, Power_fail, and Temp_fail for alert notification.
