field-replaceable units (FRUs), and spares
Always use an ESD wrist strap when handling modules or
coming into contact with internal components. Installation Guidelines
Observe the following cautions when upgrading the memory on a DFC:
Caution
Always use an ESD wrist strap when handling modules or
coming into contact with internal components.
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.
Caution
SODIMMs are sensitive components that are susceptible
to ESD damage. To prevent ESD damage, handle SODIMMs by the edges
only; avoid touching the memory modules, pins, or traces (the metal
fingers
along the connector edge of the SODIMM).
Caution
When inserting SODIMMs, use firm but not excessive
pressure. If you damage a socket, you will have to return the DFC
to the factory for repair.
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
You 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.
Verifying the DFC Memory
Table 1 lists the default memory configurations and available upgrades.
Table 1 Memory Configurations
To verify the memory configuration on the DFC, enter the remote command module mod show memory summary command, where mod is the module with an installed DFC. Add the processor and I/O totals to get the total memory for the DFC.
This example shows how to check the total memory on the DFC on a fabric-enabled module in slot 9:
Router# remote command module 9 show memory summary

The above example shows the total memory on the DFC is 256 MB.
Removing the DFC3 (WS-F6700-DFC3A, WS-F6700-DFC3B, WS-F6700-DFC3BXL Only)
For the WS-F6700-DFC3A, WS-F6700-DFC3B, and WS-F6700-DFC3BXL, the memory module is located on the base WS-X67xx module, under the DFC3. To upgrade the DFC3 memory, you must first remove the DFC3 from the module.
To remove a DFC3, follow these steps:
Warning Hazardous voltage or
energy is present on the backplane when the system is operating.
Use caution when servicing. Statement 1034
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.
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.
Step 3 Use a Phillips-head screwdriver to remove the securing
screws and the two cap nuts. (See Figure 1.)
Figure 1 Removing the Securing Screws and Cap Nuts
Step 4 Partially install the cap nut, as shown in Figure 2, about 3 turns so that there is a space of
about 1/8 inch (3.175 mm) between the bottom of the cap nut and the
top of the DFC3. The cap nut acts as a stop when you unseat the
connector so that the DFC3 does not move horizontally and cause
damage to the module.
Figure 2 Partially Installing the Cap Nut
Step 5 With your left hand, lift slightly at the location
shown in Figure 3. While lifting with your
left hand, rock the DFC3 up and down with your right hand, no more
than half an inch in either direction, to unseat the DFC3 from the
module.
Figure 3 Unseat the DFC3 from the Module
Step 6 Remove the cap nut.
Step 7 Hold the DFC3 with both hands, and gently lift the
DFC3 straight up from the module. (See Figure
4.)
Figure 4 Removing the DFC3 from the Module
Step 8 Place the removed DFC3 on an antistatic mat or
antistatic foam pad.
Step 9 Proceed to the "Removing the
SODIMM" section.
Removing the SODIMM
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 remove the existing SODIMM, follow these steps:
Step 1 Make sure that you take the necessary precautions to
prevent ESD damage.
Step 2 Remove the module with the DFC or DFC3A from the
system. (Refer to the Catalyst 6500 Series Module Installation Guide for
removal instructions.)
Step 3 Place the module on an antistatic mat or pad.
Step 4 Locate the SODIMM. (See Figure
5 for the WS-F6K-DFC, see Figure 6 for
the WS-F6K-DFC3A, and see Figure 7 for the
WS-X6700-DFC3A.)
Figure 5 Location of SODIMM on a WS-F6K-DFC
Figure 6 Location of SODIMM on a WS-F6K-DFC3A
Figure 7 Location of SODIMM on a WS-X67xx Module for the DFC3A, DFC3B, and DFC3BXL
Step 5 Release the spring clips from the SODIMM, and release
the SODIMM from the socket. (See Figure
8.)
Figure 8 Releasing the SODIMM Spring Clips
Step 6 When both ends of the SODIMM are released from the
socket, grasp the ends of the SODIMM with your thumb and
forefinger, and pull the SODIMM completely out of the socket.
SODIMMs are sensitive components that are susceptible
to ESD damage. To prevent ESD damage, handle SODIMMs by the edges
only; avoid touching the memory modules, pins, or traces (the metal
fingers along the connector edge of the
SODIMM). (See Figure 9.) Step 7 Place the SODIMM in an antistatic container to protect
it from ESD damage.
This completes the SODIMM removal procedure. Proceed to the "Installing the SODIMM" section to install the new SODIMM.
Installing the SODIMM
SODIMMs are sensitive components that are susceptible
to ESD damage. To prevent ESD damage, handle SODIMMs by the edges
only; avoid touching the memory modules, pins, or traces (the metal
fingers along the connector edge of the
SODIMM). (See Figure 9.) Figure 9 Handling a SODIMM
Follow these steps to install the new SODIMM:
Step 1 Remove a new SODIMM from the antistatic container.
Step 2 Hold the SODIMM with the component side up and with
the connector edge (the metal fingers) away from you.
Step 3 Hold the sides of the SODIMM between your thumbs and
forefingers. (See Figure 9.)
Step 4 Tilt the SODIMM to approximately the same angle as the
socket, and insert the connector edge into the socket.
When inserting SODIMMs, use firm but not excessive
pressure. If you damage a socket, you will have to return the DFC
to the factory for repair. Step 5 Press the SODIMM down until it is secured by the
spring clips. (See Figure 10.)
Figure 10 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.
Step 7 If you upgraded the memory on the WS-F6700-DFC3A,
WS-F6700-DFC3B, or WS-F6700-DFC3BXL, you need to reinstall the
DFC3. Proceed to the "Installing the DFC3
(WS-F6700-DFC3A, WS-F6700-DFC3B, WS-F6700-DFC3BXL Only)"
section to install the DFC3.
Otherwise, reinstall the module. (Refer to the Catalyst 6500 Series Module Installation Guide for removal instructions.)
Installing the DFC3 (WS-F6700-DFC3A, WS-F6700-DFC3B, WS-F6700-DFC3BXL Only)
To install the DFC3 on a WS-X67xx module, follow these steps:
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.
Step 1 Align the mounting holes on the DFC3 (see Figure 11) with the male standoffs on the module.
(See Figure 12.) Make sure that the
remaining mounting holes on the DFC3 are aligned with the remaining
standoffs.
Figure 11 Mounting Holes on the DFC3
Figure 12 Male Standoff Locations on the WS-X67xx Module
Step 2 Ensure that the connectors on the DFC3 are aligned
with the connectors on the module. Figure 13
shows the connectors on the underside of the DFC3.
Figure 13 DFC3A Connectors
Step 3 Apply pressure to the area shown in Figure 14 to seat the power connector.
Figure 14 Seating the Power Connector
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. Step 4 Apply pressure to the location shown in Figure 15 to fully seat the DFC3 on the module.
Figure 15 Seating the DFC3 on the Module
Step 5 Use a Phillips-head screwdriver to install the
securing screws and the two cap nuts. (See Figure 16.)
You 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.
Note You should visually verify that there are standoffs
beneath the mounting holes before installing the securing screws.
