  • Page 5 Multiple component failures - The chance of a random compo- nent 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 single case where multiple IC failures were not caused by misuse or accident.
  • Page 6 Notice to user n 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 damaged if the right sequence of pins contacts as the card is pushed into the socket.
