Removing a CFC or DFC Daughter Card
Note The MEM-XCEF720-1GB memory upgrade is required for the DFC3BXL upgrade only and is included
as part of the DFC3BXL daughter card kit only.
These tools and supplies are required to remove and install the DFC3 daughter card:
•Antistatic mat or foam pad to support the removed module and an antistatic bag to store the removed
Central Forwarding Card (CFC) or DFC daughter card
•Your own ESD-prevention equipment or the disposable grounding wrist strap included in the
upgrade kit
•Number 1 Phillips-head screwdriver for the DFC daughter card installation hardware
Removing a CFC or DFC Daughter Card
If your Ethernet module has either a CFC or a DFC daughter card installed, you must remove the old
CFC or DFC daughter card before installing the new DFC daughter card. The folowing procedures are
provided:
•Removing the CFC Daughter Card, page 9
•Removing the DFC3 Daughter Card, page 11
Note An additional procedure for removing DFC3 daughter cards is provided for daughter cards installed on
early versions of the WS-X6748-GE-TX Ethernet module that are equipped with stiffener brackets.
Removing the CFC 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 a CFC daughter card, 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 42 for instructions.
Step 2 Remove the 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 Ethernet Modules in the Chassis” section on page 34 for removal
instructions.
Step 3 Place the Ethernet module on an antistatic mat with the front of the module facing toward you.
Step 4 Use a Phillips-head screwdriver to remove the installation hardware, which consists of three securing
screws and the two cap nuts. (See Figure 1.)

Step 5 To unseat the CFC daughter card from the Ethernet module, hold each tab at the rear of the CFC daughter
card between your thumb and index finger, and gently press down on both tabs until the connectors are
unseated. (See Figure 2.)
Caution Do not apply too much pressure on the tabs because you might cause damage to the module.

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 that are not 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

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 34 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 your DFC daughter card has a small metal installation bracket as shown in Figure 3, 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 bracket, just remove the two cap nuts and the one screw.
Step 5 Remove the remaining installation hardware. (See Figure 3.)
Note The installation hardware shown in Figure 3 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.

Step 6 Partially reinstall the cap nut, rotating about 3 turns so that there is a space of about 1/8 inch (3 mm)
between the bottom of the cap nut and the top of the DFC3 daughter card, as shown in Figure 4. The cap
nut acts as a stop when you unseat the daughter card connector so that the DFC3 daughter card does not
move horizontally and cause damage to the base board.

Removing a CFC or DFC Daughter Card
To remove a DFC3 daughter card from a WS-X6748-GE-TX Ethernet module that is 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 42 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 Ethernet Modules in the Chassis” section on page 34 for removal
instructions.
Step 3 Place the module on an antistatic mat or antistatic 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 installation hardware. (See Figure 7.)

Upgrading the Ethernet Module Memory
When you upgrade your Ethernet module with either a DFC3BXL or DFC3CXL daughter card, you must
also install a 1-GB memory upgrade (part number MEM-XCEF720-1GB) on the Ethernet module. This
1-GB memory upgrade is included with your DFC3BXL or DFC3CXL upgrade kit and installs on the
Ethernet module in a small-outline dual-inline memory module (SODIMM) chip socket located
underneath the DFC daughter card.
Note You must perform the memory upgrade procedure after you remove the CFC or the DFC daughter card
from the Ethernet module and before you install either the DFC3BXL or DFC3CXL daughter card
upgrade.
