6. EXPANSION MODULE INSTALLATION

The Ashly 24.24M can be ordered from the factory with expansion modules pre-installed to suit the application, or

as a 4 x 4 base unit. Should the need arise to add input or output capacity at a later time, additional four channel input

or output modules can be purchased and easily installed in the field.

There are a total of four expansion slots available, and each slot accepts either an input or an output module. The

24.24M as well as Protea System Software autodetect if a slot has been filled, and whether it is an input or output. The

software interface automatically updates to reflect the current 24.24M expansion slot configuration.

Please note that while field installation is not complicated, there is a risk of ESD (electrostatic discharge) damage

to circuit board components if the board is improperly handled.

To install an additional expansion module, refer the following procedure to a qualified service technician:

1.) Remove AC power cord from back of unit and place unit on grounded work surface.

2.) Remove the seven top cover screws and remove cover. Remove expansion slot covers from back panel.

3.) Discharge any personal static by touching a grounded object. Carefully remove the new expansion card and

flat cable from the ESD protective bag.

4.) Follow the instructions in the above drawing for installing expansion modules. Ashly recommends placing

input expansion modules starting with EXP1, and placing output expansion modules starting from EXP 4 and working

backwards. This way input and output channels are continuously numbered up from channel 1.

6.) In some cases it may be necessary to remove an existing expansion card before installing an new adjacent one.

Certain motherboard flatcable headers may be inaccessible with modules installed above them.

7.) Make sure all hardware is secure, then replace top cover.

For further information on expansion module assembly or proper ESD protection, please contact the Ashly service

department at 1-800-828-6308.
