IBM CMX58886CX user manual Jumper Settings and Locations

Jumper Settings and Locations

Many cpuModule options are configured by positioning jumpers. Jumpers are labeled on the board as JP followed by a number.

Some jumpers have three pins, allowing three settings:

• Pins 1 and 2 connected (indicated as “1–2”)

• Pins 2 and 3 connected (indicated as “2–3”)

• No pins connected

1 2 3

Some jumpers have two pins, allowing two settings:

• Pins 1 and 2 connected (indicated as “closed”)

• Pins 1 and 2 unconnected (indicated as “open”)

1 2

Solder jumpers are located on the cpuModule’s bottom side. Solder blobs are factory-set and rarely changed. Contact RTD Technical Support for further information.

Figure 6 shows the jumper and solder blob locations that are used to configure the cpuModule. In both top and bottom figures, the PC/104 bus connector is at the six o'clock position. Table 57 lists the jumpers and their settings. Table 58 lists the solder blobs and their settings.
