15 Replacing Modules
A module can be removed and replaced in the field. This should be only carried out by a
competent person and all appropriate ESD precautions must be observed.
It is recommended to power down the unit before changing any card. A card can be
removed and replaced with power still applied to the unit without causing damage.
To replace a module first remove the two retaining screws. Carefully remove the board
using a flat blade screwdriver between the case and the back-panel side edges.
Remove card and place in antistatic bag.
To insert the new card, remove from antistatic bag and slide into the now vacant slot.
Carefully push home pressing on the rear metal of the module.
Use the retaining screws to secure the new card in the unit.
