AS1020C-3 User's Manual

3rd Power Supply Fail Signal Enable/Disable

The system can notify you in the event of a power supply failure. This feature assumes that three redundant power supply units are installed in the chas- sis. If you only have one or two power supplies installed, you should disable the function with the J3P header to pre- vent false alarms. See the table on the right for jumper settings.

I2C to PCI Enable/Disable

The JI2C1/2 pair of jumpers allows you to connect the System Management Bus to any one of the PCI expansion slots. The default setting is closed (on) for both jumpers to enable the connec- tion. Both connectors must be set the same (JI2C1 is for data and JI2C2 is for the clock). See the table on right for jumper settings

Compact Flash Master/Slave

The JCF1 jumper allows you to assign either master or slave status to an installed compact fl ash card. See the table on the right for jumper settings.

VGA Enable/Disable

JPG1 allows you to enable or disable the VGA port. The default position is on pins 1 and 2 to enable VGA. See the table on the right for jumper set- tings.
