Internal Connectors

The RASCard has several internal connectors, which are described from front to back.

J20 CPU Fan

This is the 5 VDC power connector for the CPU’s cooling fan.

J12 Power Switch

This is the connector for the power switch.

J8 Speaker

This connector can be used to connect a speaker to the RASCard. However, it is normally not used when more than one RASCard is installed in the CommPlete chassis.

J1, J10 E1 Card

This connector provides power, ground, and data connections for the optional E1 daughter card. It is not used on a RASCard with a PRI card.

J6 Internal Hard Disk Drive

This IDE connector provides control and data signals, power, and ground for the RASCard’s 2.5-inch hard disk drive. The control and data lines are shared with J21. Therefore, if you connect a second hard disk drive or an IDE CD-ROM drive to J21, you must configure it to slave mode by setting its jumper accordingly.

J21 IDE Drive

This connector can be used to connect a second IDE hard disk drive or a CD-ROM drive to the RASCard. The IDE control and data lines are shared with J6. There is no secondary IDE controller; if you install two hard disk drives, you must configure the second one to slave mode by setting its jumper accordingly.

J27 Floppy Drive

This connector can be used to connect a floppy disk to the RASCard, e.g., for software updates. Normally, it is not used.

J13 Drive Power

This connector can be used to supply standard voltages to a disk drive or CD-ROM drive. Normally, it is not used.

J4, J7 Bus Connectors

These two connectors connect the RASCard to the CommPlete chassis’ control, data, E1, and Ethernet busses.
