Adding and Removing Modules

Preparing your system

Be sure you have a small flat-head screwdriver before you attempt to remove or install options. You also need a screwdriver to connect cables to the back of the system unit.

Before you install or remove any module, you must take the following steps to prevent circuit damage.

• Turn off the control computer and all peripheral devices
• Turn off the system unit
• Wait about one minute. This allows time for the power supply capacitors to safely discharge.
• Remove all cables and power cords from the back of the system unit

Installing a module card

• Be sure that the system preparation tasks are complete
• Remove the screws from the front of the system unit that hold the filler plate. Save the filler plate in case you remove the module later.
• Insert the module connector into the open slot at the front of the system unit. Handle modules by their edges only.
• Firmly press the module onto the backplane connector.
• Tighten the screws that hold the module in place.
• Connect external cables if required.

Removing a module card

• Be sure that the system preparation tasks are complete.
• Loosen the screws that hold the module in place.
• Pull the module off the backplane connector and out. Handle modules by their edges only.
• Insert the filler plate and attach with two or four screws. (For factory installed optional modules filler plate is not provided.)

NOTE: In case you remove the TRNDR unit first remove the vent cover on the left. After reinstalling the TRNDR unit also insert the vent cover on the left.
