16 PC/104-Plus – COM-1460 Module
1. Turn off power to the PC/104-Plus system or stack.
2. Select and install standoffs to properly position the module on the PC/104-Plus stack.
3. Touch a grounded metal part of the rack to discharge any buildup of static electricity.
4. Remove the module from its anti-static bag.
5. Check that keying pins in the bus connector are properly positioned.
6. Check the stacking order; make sure an XT bus card will not be placed between two AT bus cards or it
will interrupt the bus’s signals.
7. Hold the module by its edges and orient it so that the bus connector pins line up with the matching
connector on the stack.
8. Press the module evenly onto the PC/104-Plus stack.
9. Verify that all the connections are properly made
10. Switch on the power
If standard PC/104 modules are used in the stack, they must be the top module(s) because they will
normally not include the PCI bus.
The following picture shows an example of a module stack with 2 PC/104-Plus modules, 1 PC/104 16-BIT
module, and 1 PC/104 8-BIT module.
The maximum number of PC/104-Plus modules is 4 plus the (PC/104-Plus compliant) CPU board.
If standard PC/104 modules are used in the stack, they must be the top module(s) because they will
normally not include the PCI bus.
If the CPU is PC/104 compliant you can only stack PC/104 modules and use only the ISA buses
on the Backplane. If the CPU is PC/104-Plus compliant you can stack both PC/104 and PC/104-
Plus modules and use both PCI and ISA buses on the Backplane.

Figure 6. The Module Stack
Do not force the module onto the stack! Wiggling the module or applying too much pressure
may damage it. If the module does not readily press into place, remove it, check for bent pins
or out-of-place keying pins, and try again.
