6.4.1 Fault finding Philosophy

The objective of this chapter is to provide sufficient information to enable the operator to rectify apparent faults or else to identify where the suspect fault might be. It is assumed that fault-finding has already been performed at a system level.

Warning: Do not remove the covers of this equipment. Hazardous voltages are present within this equipment and may be exposed if the covers are removed. Only Network trained and approved service engineers are permitted to service this equipment.

Caution: Unauthorised maintenance or the use of non-approved replacements may effect the equipment specification and invalidate any warranties.

This manual does not provide any maintenance information or procedures which would require to removal of covers.

If the following information fails to clear the abnormal condition, please contact your local reseller or Network customer care.

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:

oCheck 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.

oConfirm that the equipment hardware configuration is suitable for the purpose and has been correctly connected.

oConfirm that inappropriate operator action is not causing the problem, and that the equipment software set-up is capable of performing the required functionality.

oCheck 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.
