the suspect fault might be. It is assumed that fault-finding has already
been performed at a system level.

voltages are present within this equipment and may be exposed if the

6.4.2
Preliminary Checks
Always investigate the failure symptoms fully, prior to taking remedial
action. The operator should not remove the cover of the equipment to
carry out the fault diagnosis. The following fault-finding tasks can be
carried out:
o
Check that the PSU LED is lit. If this is not lit, replace external
equipment, power source and cables by substitution to check that
they are not defect.
o
Confirm that the equipment hardware configuration is suitable for
the purpose and has been correctly connected.
o
Confirm that inappropriate operator action is not causing the
problem, and that the equipment software set-up is capable of
performing the required functionality.
o
Check that the fans are unobstructed and working correctly.
When the fault condition has been fully investigated, and the symptoms
are identified, proceed to fault-finding according to the observed
symptoms. If the fault persists, and can not be rectified using the
instructions given in this manual, contact Network Customer Support.
Switch off the equipment if it becomes unusable, or to protect it from
further damage.
