Installing the DFC3 Daughter Card

This section contains two DFC3 installation procedures. One procedure covers installing the DFC3 daughter card on modules that are not equipped with stiffener brackets. A second procedure is included that covers installing the DFC daughter cards on WS-X6748-GE-TX modules that are equipped with stiffener brackets.

Installing the DFC3 Daughter Card on Modules Without Stiffener Brackets

To install the DFC3 on modules that do not have stiffener brackets, follow these steps:

---

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

---

---

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 from the antistatic bag and the installation hardware from the bag.

---

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 will be used in all installations. Visually verify that there are standoffs beneath the mounting holes before installing the securing screws.

---

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 18 Seating the DFC3 Daughter Card on the Module

Step 7 Use a Phillips-head screwdriver to install the securing screws and the two cap nuts. (See Figure 19.)

---

Caution You must install screws in all available standoffs. The screws provide grounding between the DFC3 daughter card and the module. Failure to install all of the 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 19 Installing the Securing Screws and Cap Nuts

Step 8 Reinstall the Ethernet module in the chassis. (If you are unsure on the correct procedure for installing a module in the switch chassis, refer to the "Removing and Installing Modules in the Chassis" section for installation instructions.)

---

Installing the DFC3 Daughter Card on Modules Equipped with a Stiffener Bracket

---

Note Some early versions of the WS-X6748-GE-TX Ethernet modules have a stiffener bracket mounted across the top front part of the module, which requires a modified procedure to install the DFC 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 install the DFC daughter card on 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 "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 bag.

---

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 will be used in all installations. Visually verify that there are standoffs beneath the mounting holes before installing the securing screws.

---

Step 3 Position the DFC3 daughter card over the module, and slightly tilt the DFC3 daughter card so that the back end will clear the module connectors.

Step 4 Carefully slide the DFC3 under the two stiffener bracket tabs. (See Figure 20.) Verify that the DFC daughter card is under the two stiffener bracket tabs.

---

Caution You must position the DFC daughter card under the two stiffener bracket tabs. If you install the DFC daughter card above the two stiffener bracket tabs, you can permanently damage the DFC daughter card.

---

Step 5 Align the mounting holes on the DFC3 daughter card with the male standoffs on the module. (See Figure 20.) Make sure that the remaining mounting holes on the DFC3 daughter card are aligned with the remaining standoffs.

Caution Do not overtighten the screws and the cap nuts because you will damage the board.

---

Figure 22 Installing the Screws and Cap Nuts (WS-X6748-GE-TX Equipped with a Front Stiffener Bracket)

---

Caution You must install screws in all available standoffs. The screws provide grounding between the DFC3 daughter card and the module. Failure to install all screws will invalidate the safety approvals and pose 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 a module in the switch chassis, refer to the "Removing and Installing Modules in the Chassis" section for installation instructions.)

---

Removing and Installing Modules in the Chassis

This section describes how to correctly remove and install a 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 a Module from the Chassis

To remove a module from the chassis, perform these steps:

---

Step 1 Disconnect any network interface cables or console port cables attached to the module.

Step 2 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 3 Verify that the captive installation screws on all of the modules in the chassis are tight. This step assures 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 will push the modules toward the open slot, reducing the opening size and making it difficult to reinstall the module.

---

Step 4 Loosen the two captive installation screws on the 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, and simultaneously rotate the levers outward to unseat the module from the backplane connector.

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

Vertical slots

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

b. Grasp the edges of the module, and slide the module straight out of the slot. Do not touch the module circuitry.

Step 6 Place the module on an antistatic mat or antistatic foam.

---

To install a module in the chassis, perform 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 Verify that the captive installation screws are tightened on all modules installed in the chassis. This assures that the EMI gaskets on all modules are fully compressed in order to maximize the opening space for the new module or the replacement module.

---

Note If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, reducing the opening size and making it difficult to reinstall the module.

---

Step 3 Fully open both ejector levers on the module. (See Figure 23.)

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 module in the slot. (See Figure 23.) Make sure that you align the sides of the module carrier with the slot guides on each side of the slot.

b. Carefully slide the 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 closed to approximately 45 degrees with respect to the module faceplate. (See Figure 24.)

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 24.)

---

Caution Do not press down too hard on the levers. They will bend and be damaged.

---

d. While gently pressing down, simultaneously close the left and right ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 25.)

---

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

---

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

---

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

---

f. Verify that the 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.

Vertical slots

a. Position the module in the slot. (See Figure 26.) Make sure that you align the sides of the module carrier with the slot guides on the top and bottom of the slot.

b. Carefully slide the module into the slot until the EMI gasket along the right edge of the module 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 module faceplate. (See Figure 27.)

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 27.)

---

Caution Do not exert too much pressure on the ejector levers. They will bend and be damaged.

---

d. While gently pressing on the ejector levers, simultaneously close them to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 28.)

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

---

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

---

f. Verify that the 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 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 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 most FRUs 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 29):

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 29 Attaching the ESD Wrist Strap Clip to the System Ground Lug Screw

---

In addition, follow these guidelines when handling modules:

•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).

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
