Installing the DFC3 Daughter Card

Figure 13 Installing the SODIMM

Step 6

When the SODIMM is installed, check the two alignment holes, and ensure that the spring retainer is

visible. If it is not, the SODIMM is not seated properly. If any SODIMM appears misaligned, carefully

remove it and reseat it in the socket. Push the SODIMM firmly back into the socket until the retainer

springs snap into place.

Installing the DFC3 Daughter Card

This section contains two DFC3 installation procedures. One procedure covers installing the DFC3

daughter card on modules that are not equipped with stiffener brackets. A second procedure is included

that covers installing the DFC daughter cards on WS-X6748-GE-TX modules that are equipped with

stiffener brackets.

Installing the DFC3 Daughter Card on Modules Without Stiffener Brackets

To install the DFC3 on modules that do not have stiffener brackets, follow these steps:

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

Step 1 Attach an ESD grounding strap to your wrist and to ground. (If you are unsure about the correct way to

attach an ESD grounding strap, refer to the “Attaching Your ESD Grounding Strap” section on page 40

for instructions.)

Step 2 Remove the new DFC3 from the antistatic bag and the installation hardware from the bag.

Note The DFC3 daughter card is designed to be installed on different modules; therefore, there may

be more mounting holes on the DFC3 daughter card than there are standoffs on the module. Not

all mounting holes on the DFC3 daughter card will be used in all installations. Visually verify

that there are standoffs beneath the mounting holes before installing the securing screws.

Step 3 Align the mounting holes on the DFC3 daughter card (see Figure 14) with the male standoffs on the

module. (See Figure 15.) Make sure that the remaining mounting holes on the DFC3 daughter card are

aligned with the remaining standoffs on the module.
