Removing a CFC or DFC3 Daughter Card

Removing the DFC3 Daughter Card

If your WS-X67xx Ethernet module is equipped with a DFC3 daughter card, you must remove it before

you install the 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 remove the DFC3 daughter card from modules, follow these steps:

Step 1 Attach an ESD grounding strap to your wrist and to ground.

Step 2 Remove the Ethernet module from the chassis.

If you are unsure about the correct procedure for removing a module from the switch chassis, refer to

the “Removing an Ethernet Module from the Chassis” section on page 28 for removal instructions.

Step 3 Place the Ethernet module on an antistatic mat with the front of the module facing toward you.

Step 4 If you are upgrading a WS-X6748-GE-TX Ethernet module with a DFC4 daughter card and your

WS-X4748-GE-TX module is equipped with a stiffener bracket that goes across the top of the heat sinks

at the front of the module (see Figure 1), you must first remove the stiffener bracket before continuing

with the CFC daughter card removal procedure. To remove the bracket, follow these substeps:

a. Loosen and remove the six phillips-head screws that secure the bracket to the module.

b. Carefully lift and remove the bracket from the module.

Caution Do not reinstall the stiffener bracket. After upgrading the WS-X6748-GE-TX Ethernet module with a

DFC4 daughter card, the bracket can be discarded.

Step 5 If your DFC daughter card has a small metal installation bracket as shown in Figure 4, use a No.1

Phillips-head screwdriver to remove the two cap nuts and the one screw securing the bracket. Set them

aside along with the bracket. If there is no bracket, just remove the two cap nuts and the one screw.

Step 6 Remove the remaining installation hardware. (See Figure 4.)

Note The installation hardware shown in Figure 4 is for a DFC3B or DFC3BXL daughter card. The

installation hardware for a DFC3C or a DFC3CXL daughter card consists of 6 screws, 2 cap nuts,

and 1 standoff.
