Power sequencing The major failure of 1 O chips is caused by the external application of input voltage while the Micro PC power is off If you apply 5V to the input of a TTL chip with the power off nothing will happen Applying a 5V input to a CMOS card will cause the current to flow through the input and out the 5V power pin This current attempts to power up the card Most inputs are rated at 25 mA maximum When this is exceeded the chip may be damaged Failure on power up Even when there is not enough current to destroy an input described above the chip may be destroyed when the power to the card is applied This is due to the fact that the input current biases the IC so that it acts as a forward biased diode on power up This type of failure is typical on serial interface chips Serial and parallel Customers sometimes connect the serial and printer devices to the Micro PC while the power is off This can cause the failure mentioned in the above section Failure upon power up Even if they are connected with the Micro PC on there can be another failure mechanism Some serial and printer devices do not share the same power AC grounding Theleakage can causethe serial or parallel signals to be 20 40V above the Micro PC ground thus damaging the ports as they are plugged in This would not be a problem if the ground pin is connected first but there is no guarantee of this Damagetothe printer port chip will cause the serial ports
3. In a 7 year study Octagon has never found a single case where multiple IC failures were not caused by misuse or accident It is very probable that multiple component failures indicate that they were user induced Testing dead cards For a card that is completely nonfunctional there is a simple test to determine accidental over voltage reverse voltage or other forced current situations Unplug the card from the bus and remove all cables Using an ordinary digital ohmmeter on the 2 000 ohm scale measure the resistance between power and ground Record this number Reverse the ohmmeter leads and measure the resistance again If the ratio of the resistances is 2 1 or greater fault conditions most likely have occurred A common cause is miswiring the power supply 2430 Super VGA Video Card 3 Improper power causes catastrophic failure f a card has had reverse polarity or high voltage applied replacing a failed component is not an adequate fix Other components probably have been partially damaged or a failure mechanism has been induced Therefore a failure will probably occur in the future For such cards Octagon highly recommends that these cards be replaced Other over voltage symptoms n over voltage situations the programmable logic devices EPROMs and CPU chips usually fail in this order The failed device may be hot to the touch It is usually the case that only one IC will be overheated at a time
