problem persists, consult the Altus Technical Support.
Symptom
Possible Cause
Solution
Does not
power on
Lack of power
supply or incorrectly
powered
Check if the CPU is properly connected in the rack.
Power off and take off all modules from the bus, but the
CPU and the power supply.
Power on the bus and check the power supply functioning,
both external and the one connected to the rack.
Check if the supply voltage gets to the Hadron Xtorm power
supply contacts and if is correctly polarized.
Does not
communicate
Bad contact or bad
configuration
Check all the connections of the communication cables.
Check the serial and Ethernet interfaces configuration in the
MasterTool Xtorm software.
Does not
recognize the
memory card
Bad connection or
not mounted
Check if the memory card is properly connected in the
compartment.
Check if the memory card is in the right side, as indicated
on the CPU frontal panel.

Preventive Maintenance
It must be annually verified if the interconnection cables are firmly connected, without dust
accumulation, mainly the protection devices.
In environments likely to excessive contamination, the equipment must be periodically cleaned
from dust, debris, etc.
The TVS diodes used for transient protection caused by atmospheric discharges must be
periodically inspected, as they might be damaged or destroyed in case the absorbed energy is
above limit. In many cases, the failure may not be visual. In critical applications, it is
recommended the periodic replacement of the TVS diodes, even if they do not show visual
signals of failure.
Bus tightness and cleanness every six months.
