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 single case where multiple IC failures were not caused by misuse or accident. -
Page 5: Avoiding Damage To The Heatsink Or Cpu
Excessive signal lead lengths: Another source of failure that was identified years ago at Octagon was excessive lead lengths on digital inputs. Long leads act as an antenna to pick up noise. They can also act as unterminated transmission lines. When 5V is switched onto a line, it creates a transient waveform. -

Table 15–2 J9 – CPU fan connector J9 – CPU fan connector Pin # Pin Name tachometer control Integrated Conductive Cooling System (ICCS) The Integrated Conductive Cooling System provides a rugged passive cooling enclosure for the XE–900. The heat sink dissipates heat from the CPU throughout the all-aluminum assembly, ensuring that the temperature of the microprocessor stays close to that of the system environment. -

If video is present but is distorted, check the following: Make sure all PC/104 or PC/104-Plus expansion cards are removed from the XE–900 SBC. This ensures that other cards are not interacting with the XE– 900 SBC. Turn the “S” switch Off. ... -
Page 95: System Generates A Bios Message But Locks Up When Booting
System locks up on power-up; may or may not respond to reset switch A common cause is using a non-Octagon power supply such as a PC desktop supply. Most of these PC supplies are rated at 5V at 20A or more. Switching supplies usually requires a 20% load to operate properly, that is, 4A or more. -

This card is guaranteed to operate over the published temperature ranges and relevant conditions. However, sustained operation near the maximum temperature specification is not recommended by Octagon or the CPU chip manufacturer due to well known, thermal related, failure mechanisms. These failure mechanisms, common to all silicon devices, can reduce the MTBF of the cards. -
