Removing the DFC3 Daughter Card

To remove a DFC3 daughter card from a WS-X6748-GE-TX Ethernet module equipped with a stiffener

bracket, follow these steps:

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 WS-X6748-GE-TX Ethernet module from the Catalyst 6500 series switch. (If you are

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

“Removing and Installing Modules in the Chassis” section on page 32 for removal instructions.)

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

Step 4 If your DFC daughter card has a small metal installation bracket as shown in Figure 7, use a No.1

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

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

Step 5 Use a Phillips-head screwdriver to remove the remaining securing screws. (See Figure 7.)
