As expected virtually all the failures occur when bringing up the first system On subsequent systems the failure rate drops dramatically W Approximately 2096 of the returned cards are problem free These cards typically have the wrong jumper settings or the customer has problems with the software This causes frustration for the customer and incurs a testing charge from Octagon m Of the remaining 80 of the cards 9096 of these cards fail due to customer misuse and accident Customers often cannot pinpoint the cause of the misuse Therefore 72 of the returned cards are damaged through some type of misuse Of the remaining 896 Octagon is unable to determine the cause of the failure and repairs these cards at no charge if they are under warranty The most common failures on CPU cards are over voltage of the power supply static discharge and damage to the serial and parallel ports On expansion cards the most common failures are static discharge over voltage of inputs over current of outputs and misuse of the CMOS circuitry with regards to power supply sequencing In the case of the video cards the most common failure is to miswire the card to the flat panel display Miswiring can damage both the card and an expensive display m Multiple component failures The chance of a random component failure is very rare since the average MTBF of an Octagon card is greater than 11 years In a 7 year study Octagon has never found a

15. e the Chips amp Technolo gies video chip The problem is due to flat panels having connector pins that are not clearly marked and assumptions are made as to the location of pin 1 For example Sharp LM32008F and other Sharp Quarter VGA panels have this problem The silk screen for CN1 on these panels is placed next pin 12 This causes the user to assume that pin 12 is pin 1 and as a result the panel is wired backwards This in turn causes damage to the video chip Carefully read the flat panel documentation and diagrams which clearly identify the placement of pin 1 so that damage to the 5420 can be avoided Octagon assumes no responsibility for any damage caused to flat panel displays and or Micro PC video cards if the display is connected incorrectly CN1 This is PIN 1 Figure 4 LM32008F Quarter VGA Panel 5420 Super VGA Video Card 10 The following table lists the pin number and function for the flat panel connector at J 1 Flat Panel Connector J 1 Function 1 ACDCLK 3 FLM Gnd 5 LP Gnd 7 BLANK Gnd 9 SHFCLK Gnd 111 ENAVDD 12 Gna 13 PNL0 a 15 PNL1 16 27 PNL2 18 19 PNL3 20 Vdd 45V 2 Vdd 45V 22 Vee2 23 Vee2 24 Vee 25 Vee 26 PNL4 27 Gnd 28 PNL5 29 Gnd 30 PNL6 31 Gnd 32 PNL7 33 Gnd 34 PNL8 35 Gnd 36 PNL9 37 Gnd 38 PNL10 39 Gnd 40 PNL11 a Gnd 42 PNL12 a 44 PNL13 45 a P
