Module Testing and Removal
Section 5: Module Testing and Removal
5.1 Module Lanyard Attachment
Daktronics recommends attaching a module lanyard (located in the spare parts box) whenever
removing a module. To attach a module lanyard:
1. Attach one end of the module lanyard to a lanyard attachment ring on the top of the of
the module.
2. Feed the lanyard over a wire rod or through a nearby upright. Do not anchor the module
to another module.
3. Attach the other end of the module lanyard to the lanyard attachment ring on the top of
the module.
5.2 Removing a Module from the Display Face (Front Access)
Required Tools:
1
/
8
" hex wrench, module lanyard (from the spare parts box)
To remove a module from the front:
1. With one hand on the module face, insert the
1
/
8
" hex
wrench into the bottom access hole. Refer to
2. Turn the latch release approximately a quarter-turn
counterclockwise.
3. Insert the
1
/
8
" hex wrench into the top access hole.
4. Turn the latch release approximately a quarter-turn
counterclockwise. You should feel the module release
from the display face.
5. Pull the module from the display face just far enough
to reach the back of the module.
6. Disconnect the power and SATA cables from the back of the module.
7. Gently place the module on a clean and dry surface.
Note: If there is no place to set the module, use a safety lanyard to hang the module
from the back of the display. Attach the safety lanyard in a way that takes up slack on
the lanyard. Carefully let the module hang while ensuring it does not damage LEDs or
louvers.
5.3 Reinstalling the Module (Front Access)
1. Reinstall the module by aligning it with the opening.
2. Reattach the power and SATA cables.
3. Carefully insert the module into the opening while verifying that SATA and power cables are
not being pinched between the module and display face.
4. Firmly press the lower half of the module against the display face.
