Step 6
Use a Phillips-head screwdriver to install the installation hardware:
a. For the DFC4-A and the DFC4-AXL daughter cards, install the 9 screws and the 2 standoffs. (See
Figure 17.)
b. For the DFC4-E and the DFC4-EXL daughter cards, install the 6 screws, 2 cap nuts, and 1 standoff.
(See Figure 18.)
Caution Yo u must install all of the installation hardware. The screws provide grounding between the DFC4
daughter card and the Ethernet module. Failure to install all of the screws will invalidate the safety
approvals and create a risk of fire and electrical hazard.
Note You should visually verify that there are standoffs beneath the mounting holes before installing
the installation hardware.
