Safety Overview
DFC3A, DFC3B, DFC3BXL Hardware and Software Requirements
To install and use the DFC3A, DFC3B, or DFC3BXL, you need the following:
•Catalyst 6500 series switch (Catalyst 6503, 6506, 6509, 6509-NEB, or 6513) or Cisco 7600 series
router (Cisco 7603, 7606, 7609, or 7613)
•Supervisor Engine 720 with MSFC3 running Cisco IOS software on the Supervisor Engine 720 and
MSFC3
Note You cannot have a DFC3A, DFC3B, or DFC3BXL in a system with a Supervisor Engine 2.
•Fabric-enabled module
Note Supervisor Engine 720 supports a DFC3A, DFC3B, or DFC3BXL on these WS-X6516-GBIC hardware
revisions:
•Lower than 5.0
•5.4 and higher
Supervisor Engine 720 does not support a DFC3A, DFC3B, or DFC3BXL on WS-X6516-GBIC
hardware revisions 5.0 through 5.3. With a Supervisor Engine 720 and with a DFC3A, DFC3B, or
DFC3BXL installed, WS-X6516-GBIC hardware revisions 5.0 through 5.3 do not power up.
Without a DFC3A, DFC3B, or DFC3BXL, WS-X6516-GBIC hardware revisions 5.0 through 5.3 operate
in bus mode.

Removing the DFC
Caution Use care not to damage the connectors on the module. If you damage a connector, it will be
necessary to return the module to Cisco for repair.
Caution Yo u must install screws in all available standoffs. The screws provide grounding between the
DFC3 and the module. Failure to install all screws will invalidate the safety approvals and
pose a risk of fire and electrical hazard.
Removing the DFC
Note Throughout this publication, unless otherwise noted, the term DFC refers to the DFC, DFC3A, DFC3B,
and DFC3BXL.
Note The figures in this procedure show the DFC. The procedure is the same for the DFC, DFC3A, DFC3B,
and DFC3BXL.
Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the module. Do not directly
touch the backplane with your hand or any metal tool, or you could shock yourself.
To remove the DFC, perform these steps:
Step 1 Remove the module from the Catalyst 6500 series switch. (Refer to the Catalyst 6500 Series Switch
Module Installation and Verification Note for removal instructions.)
Step 2 Place the module on an antistatic mat or foam, with the front of the module facing toward you.
Step 3 Use a Phillips-head screwdriver to remove the securing screws and the two cap nuts from the DFC.
(See Figure 1.)

Installing the DFC
Installing the DFC
Note Throughout this publication, unless otherwise noted, the term DFC refers to the DFC, DFC3A, DFC3B,
and DFC3BXL.
Note The figures in this procedure show the DFC. The procedure is the same for the DFC, DFC3A, DFC3B,
and DFC3BXL.
Caution 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.
To install the DFC on a fabric-enabled module, follow these steps:
Step 1 Remove the module from the Catalyst 6500 series switch. (Refer to the Catalyst 6500 Series Module
Installation Guide for removal instructions.)
Step 2 Place the module on an antistatic mat or foam, with the front of the module facing toward you
(see Figure 6).
Step 3 Remove the DFC from its antistatic bag.
Step 4 Align the two mounting holes on the DFC (see Figure 5) with the two male standoffs on the module
(see Figure 6). Make sure that the remaining mounting holes on the DFC are aligned with the remaining
standoffs.
Note The DFC is designed to be installed on different modules; therefore, there may be more
mounting holes on the DFC than there are standoffs on the module. Not all mounting holes on
the DFC will be used in all installations. Visually verify that there are standoffs beneath the
mounting holes before installing the securing screws.

Step 6 Apply pressure to the area shown in Figure 8 to seat the power connector.
Figure 8 Seating the Power Connector
Caution The following step shows how to preseat the DFC on the module. Preseating the DFC allows you to
verify that the keys on the connectors are properly aligned. Fully seating the DFC when the connectors
are not aligned will damage the connectors on both the DFC and the module. If you damage a connector,
you will have to return the module to Cisco for repair. It is important that the DFC is preseated prior to
being fully seated.
Step 7 With your left hand, apply firm pressure at the location shown in Figure 9. While applying pressure with
your left hand, move the DFC up and down with your right hand, no more than half an inch in either
direction, to preseat the DFC on the module.

Step 8 Verify that the keys on the connector are aligned and that the gap between the key and the opposing
connector is no more than 1/16 inch (1.6 mm) before fully seating the module (see Figure 10):
•If the keys are not aligned, remove the DFC and repeat Step 4 through Step 7.
•If the keys are not seated far enough, repeat Step 7.

Installing the DFC
Figure 11 Seating the Distributed Forwarding Card on the Module
Note The DFC is fully seated when there is no gap between the connector keys, and the bottom of the
DFC is in contact with the tops of the standoffs (see Figure 10).
Caution Using the screws to seat the DFC could warp the card. Before you install and tighten the securing screws,
ensure that the DFC is fully seated by visually verifying that there is no gap between the male and female
keys on the connectors and that the bottom of the DFC is in contact with the tops of the standoffs
(see Figure 10).
Step 10 Use a Phillips-head screwdriver to install the two screws at the front of the DFC and the one screw at the
power connector in the order shown in Figure 12.
Note You should visually verify that there are standoffs beneath the mounting holes before installing the
securing screws.

Catalyst 6500 Series DFC, DFC3A, DFC3B, and DFC3BXL Installation Note
78-11627-04
Installing the DFC
Step 12 Use a Phillips-head screwdriver to install the remaining screws (see Figure 14).
Caution Yo u must install screws in all available standoffs. The screws provide grounding between the DFC and
the module. Failure to install all screws will invalidate the safety approvals and pose a risk of fire and
electrical hazard.
Note You should visually verify that there are standoffs beneath the mounting holes before installing the
securing screws.
Figure 14 Installing the Remaining Screws
Step 13 Install the module in the Catalyst 6500 series switch.
Refer to the Catalyst 6500 Series Module Installation Guide for installation instructions.
Step 14 Power up the switch.
If the switch comes online, the system acknowledges the module and the DFC. The switch brings the
module and DFC online.
