If the memory module appears misaligned, carefully remove it and reseat it in the socket. Push the memory module firmly back into the socket until the spring clips snap into place.


Installing the DFC3B and DFC3C Daughter Cards

This section contains two DFC3 installation procedures:

Installing the DFC3B, DFC3BXL, DFC3C, and DFC3CXL Daughter Cards on Ethernet Modules without Stiffener Brackets

Installing the DFC3B, DFC3BXL DFC3C, and DFC3CXL Daughter Cards on Ethernet Modules Equipped with a Stiffener Bracket

The first procedure describes how to install the DFC3 daughter card on Ethernet modules that are not equipped with a stiffener bracket. The second procedure describes how to install the DFC daughter cards on early versions of the WS-X6748-GE-TX Ethernet module that are equipped with stiffener brackets.


Note If you are installing either a DFC3BXL or DFC3CXL daughter card, you must also upgrade the Ethernet module memory to 1 GB. You must perform this memory upgrade procedure before you install the DFC3BXL or DFC3CXL daughter card.



Note Not all WS-X6748-GE-TX Ethernet modules will have the stiffener bracket installed.


Installing the DFC3B, DFC3BXL, DFC3C, and DFC3CXL Daughter Cards on Ethernet Modules without Stiffener Brackets


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 install the DFC daughter cards on Ethernet modules that do not have stiffener brackets, 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 for instructions.

Step 2 Remove the new DFC3 daughter card from the antistatic bag and the installation hardware from the packaging.


Note The DFC3 daughter card is designed to be installed on different modules; therefore, there may be more mounting holes on the DFC3 daughter card than there are standoffs on the module. Not all mounting holes on the DFC3 daughter card are used in all installations. Visually verify that there are standoffs beneath the mounting holes before installing the installation hardware.


Step 3 Align the mounting holes on the DFC3 daughter card (see Figure 14) with the male standoffs on the module. (See Figure 15.) Make sure that the remaining mounting holes on the DFC3 daughter card are aligned with the remaining standoffs on the module.

Figure 14 Mounting Holes on the DFC3 Daughter Card

Figure 15 Male Standoff Locations on the WS-X67xx Modules

Step 4 Ensure that the connectors on the DFC3 are aligned with the connectors on the module. Figure 16 shows the connectors on the underside of the DFC3.

Figure 16 DFC3 Daughter Card Connectors (Underside of DFC Daughter Card Shown)

Step 5 Apply pressure to the area shown in Figure 17 to seat the power connector.

Figure 17 Seating the Power Connector


Caution Use care not to damage the connectors on the module. If you damage a connector, you will need to return the module to Cisco for repair.

Figure 24 Installing the DFC3C and DFC3CXL Installation Hardware (WS-X6748-GE-TX Equipped with a Front Stiffener Bracket)


Caution You must install all of the installation hardware. The screws provide grounding between the DFC3 daughter card and the module. Failure to install all of the screws invalidates the safety approvals and presents a risk of fire and electrical hazard.

Step 10 Reinstall the Ethernet module in the chassis.

If you are unsure about the correct procedure for installing the Ethernet module in the switch chassis, refer to the "Installing an Ethernet Module in the Chassis" section for installation instructions.


Removing and Installing Ethernet Modules in the Chassis

This section describes how to correctly remove and install an Ethernet module in a Catalyst 6500 series switch chassis slot.


Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the card.


Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 272


Removing an Ethernet Module from the Chassis

To remove an Ethernet module from the chassis, perform these steps:


Step 1 Disconnect any network interface cables attached to the Ethernet module.

Step 2 Attach an ESD grounding strap to your wrist and to a proper ground.

If you are unsure about the correct way to attach an ESD grounding strap, refer to the "Attaching Your ESD Grounding Strap" section for instructions.

Step 3 Verify that the captive installation screws on all of the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.


Note If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on the installed modules expand and push the modules toward the open slot, which reduces the opening size and makes it difficult to reinstall the module.


Step 4 Loosen the two captive installation screws on the Ethernet module.

Step 5 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of substeps:

Horizontal slots

a. Place your thumbs on the left and right ejector levers located on the left and right sides of the module faceplate, and simultaneously rotate the levers outward to unseat the Ethernet module from the chassis backplane connector.

b. Grasp the front edge of the Ethernet module and slide the module part of the way out of the slot. Place your other hand under the Ethernet module to support the weight of the module. Do not touch the module circuitry.

c. Place the removed Ethernet module on a properly grounded antistatic mat or antistatic foam.

Vertical slots

a. Place your thumbs on the ejector levers located at the top and bottom of the Ethernet module, and simultaneously rotate the levers outward to unseat the Ethernet module from the chassis backplane connector.

b. Grasp the front edge of the Ethernet module and slide the module part of the way out of the slot. Place your other hand under the Ethernet module to support the weight of the module. Do not touch the module circuitry.

c. Place the removed Ethernet module on a properly grounded antistatic mat or antistatic foam.

Caution To prevent ESD damage, handle modules by the carrier edges only and wear grounding wrist straps.


Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051


To install a module in the chassis, perform these steps:


Step 1 Verify that an ESD grounding strap is attached to your wrist and to proper ground.

If you are unsure about the correct way to attach an ESD grounding strap, refer to the "Attaching Your ESD Grounding Strap" section for instructions.

Step 2 Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step assures that the EMI gaskets on all of the installed modules are fully compressed in order to maximize the opening space for the Ethernet module.


Note If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on the installed modules expand and push the modules toward the open slot, which reduces the opening size and makes it difficult to reinstall the module.


Step 3 Fully open both ejector levers on the Ethernet module. (See Figure 25.)

Step 4 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of substeps:

Horizontal slots

a. Position the Ethernet module in the slot. (See Figure 25.) Make sure that you align the edges of the module carrier with the slot guides on each side of the slot.

b. Carefully slide the Ethernet module into the slot until the EMI gasket along the top edge of the module makes contact with the module in the slot above it and both ejector levers have engaged and closed to approximately 45 degrees with respect to the Ethernet module faceplate. (See Figure 26.)

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create a small (0.040 inch [1 mm]) gap between the module's EMI gasket and the module above it. (See Figure 26.)


Caution Do not press down too hard on the levers because they can bend and be damaged.

d. While gently pressing down, simultaneously close the left and right ejector levers to fully seat the Ethernet module in the chassis backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 27.)


Note Failure to fully seat the module in the chassis backplane connector can result in error messages.


e. Tighten the two captive installation screws on the Ethernet module.


Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.


f. Verify that the Ethernet module STATUS LED is lit. Check the STATUS LED periodically. If the STATUS LED changes from orange to green, the module has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the module has not successfully completed the boot process and may have encountered an error.

Figure 27 Ejector Lever Closure in a Horizontal Slot Chassis

Vertical slots

a. Position the Ethernet module in the slot. (See Figure 28.) Make sure that you align the edges of the module carrier with the slot guides on the top and bottom of the chassis slot.

b. Carefully slide the Ethernet module into the slot until the EMI gasket along the right edge of the module faceplate makes contact with the module in the slot adjacent to it and both ejector levers have closed to approximately 45 degrees with respect to the Ethernet module faceplate. (See Figure 29.)

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and exert a slight pressure to the left, deflecting the module approximately 0.040 inches (1 mm) to create a small gap between the module's EMI gasket and the module adjacent to it. (See Figure 29.)


Caution Do not exert too much pressure on the ejector levers because they can bend and be damaged.

d. While gently pressing on the ejector levers, simultaneously close them to fully seat the Ethernet module in the chassis backplane connector. The ejector levers are fully closed when they are flush with the Ethernet module faceplate. (See Figure 30.)

e. Tighten the two captive installation screws on the Ethernet module.


Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.


f. Verify that the Ethernet module STATUS LED is lit. Check the STATUS LED periodically. If the STATUS LED changes from orange to green, the module has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the module has not successfully completed the boot process and may have encountered an error.

Attaching Your ESD Grounding Strap

Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD grounding strap attached to a properly grounded bare metal surface when handling modules.

Follow these guidelines for preventing ESD damage:

Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All Catalyst 6500 series chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the chassis front panel.

If you have an older Catalyst 6500 series chassis equipped with a plastic banana plug connector, we recommend that you use either the supplied ESD grounding wrist strap (with a metal clip) or an ESD grounding wrist strap equipped with an alligator clip.

If you have a newer Catalyst 6500 series chassis that has a bare metal hole as the banana plug connector (also identified by the ground symbol next to the connector), we recommend that you use a personal ESD grounding strap equipped with a banana plug.

If you choose to use the disposable ESD wrist strap supplied with the chassis or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.


Note This system ground is also referred to as the network equipment building system (NEBS) ground.


If your chassis does not have the system ground attached, you must install the system ground lug. Refer to the online Catalyst 6500 Series Switches Installation Guide for the procedure.


Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis.


After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:


Step 1 Attach the ESD wrist strap to bare skin as follows:

a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.

b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows (See Figure 31):

a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.


Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.


b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.

Figure 31 Attaching the ESD Wrist Strap Clip to the System Ground Lug Screw


When handling modules, follow these additional guidelines:

Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.

Never attempt to remove the printed circuit board from the metal carrier.


Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).
