INSTALLING THE UTILITYMODULE

Since the utilityModule uses a PC/104 stackthrough bus, the only hardware installation you will do

is placing the module to the PC/104 stack. To do this, you will connect the PC/104 bus connector

with the matching connector of another module.

Recommended Procedure

We recommend you follow the procedure below to ensure that stacking of the modules does not

damage connectors or electronics.

•

Turn off power to the PC/104 system or stack.

•

Select and install standoffs to properly position the utilityModule on the PC/104 stack.

•

Touch a grounded metal part of the stack to discharge any buildup of static electricity.

•

Remove the utilityModule from its anti-static bag.

•

Check that keying pins in the PC/104 bus connector are properly positioned.

•

Check the stacking order: make sure an XT bus card will not be placed between two AT bus

cards, or it will interrupt the AT bus signals.

•

Hold the utilityModule by its edges and orient it so the bus connector pins line up with the

matching connector on the stack.

•

Gently and evenly press the utilityModule onto the PC/104 stack.

CAUTION: Do not force the module onto the stack! Wiggling the module or applying too much

force 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.

Connecting the utilityModule

The following sections describe connectors of the utilityModule.

Finding Pin 1 of Connectors

A white area silk-screened on the PC board indicates pin 1 of connectors. A square solder pad

visible on the bottom of the PC board also indicates it.
