  • Page 22: Safety Precautions

    Safety Precautions Warning! Always completely disconnect the power cord from your chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card.

  • Page 23: Jumper Settings

    A pair of needle-nose pliers may be useful when setting jumpers. 1.8.2 CMOS clear (J1) The PCA-6276 CPU card contains a jumper that can erase CMOS data and reset the system BIOS information. Normally this jumper should be set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed.
