Installing a DFC4 Daughter Card
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly
touch the backplane with your hand or any metal tool, or you could shock yourself.
Statement 94
To install a DFC4 daughter card on an Ethernet module, follow these steps:
Step 1 Attach an ESD grounding strap to your wrist and to ground.
Step 2 Remove the new DFC4 daughter card and the mounting hardware from the packaging.
Note The DFC4 daughter card is designed to be installed on different modules; therefore, there may
be more mounting holes on the DFC4 daughter card than there are standoffs on the module. Not
all mounting holes on the DFC4 daughter card are used in all installations. Visually verify that
there are standoffs beneath the mounting holes before installing the mounting hardware.
Step 3 Align the mounting holes on the DFC4 daughter card (see Figure 13) with the male standoffs on the
module. (See Figure 14.) Make sure that the remaining mounting holes on the DFC4 daughter card are
aligned with the remaining standoffs on the module.
