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.

To remove a module from the front complete the
following steps:
1� Insert the

″ hex head wrench into the top access
hole.
2� Turn the latch release approximately a quarter-turn
counterclockwise. You should feel the module release
from the display face.
3� Pull the module from the display face just far enough
to reach the back of the module.
4� Disconnect the power and SATA cables from the back of the module.
5� 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, louvers, or gasket.

1� Reinstall the module by aligning it with the opening.
2� Reattach the power and SATA cables.
3� Carefully hook the module into the module sheet and rotate the module top to the
module sheet. Verify that SATA and power cables are not being pinched between
the module and display face.
