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,... - Page 5 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...
- Page 6 Hot insertion - Plugging cards into the card cage with the power on will usually not cause a problem. (Octagon urges that you do not do this!) However, the card may be dam- aged if the right sequence of pins contacts as the card is pushed into the socket.
