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.

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



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.


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


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 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.


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). (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


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). (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.


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.

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:


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.


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


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.

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.)


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.


Note You should visually verify that there are standoffs beneath the mounting holes before installing the securing screws.
