3.5 EAM Removal/Replacement
The MODULRAC/SIXRAC may remain powered while removing or installing a module.
3.5.1 Removal Procedure
1. As shown in Figure 2-7, pull open the bezel’s pivoted top and bottom handles to expose the module’s
slotted captive mounting screws. Loosen the screws.
2. Grasp the top and bottom handles and pull the module from the rack.
3. Place the module in a static shielding bag and package for return. Refer to section 3.10 for return
instructions.
3.5.2 Replacement Procedure
1. Remove the replacement EAM from its protective bag. The module may be safely handled, as the
circuit card is shielded from access by protective covers.
2. Insert the EAM in its MODULRAC slot. Firmly seat the module in the backplane and termination
board connectors. A properly seated module will have the rear of its bezel flush against the
MODULRAC housing rails.
A keyed module that is not matched to a slot will not engage the backplane or termination board
connectors or seat flush against the MODULRAC’s front rails.
3. As shown in Figure 2-7, pull open the bezel’s pivoted top and bottom handles to expose the module’s
slotted captive mounting screws and secure the module to the top and bottom rails. Close the bezel’s
handles when finished.
IMPORTANT
Do not use the captive mounting screws to seat the module. Damage to
the bezel can result.
