Switch Fabric Overview Switch Fabric Overview The switch fabric for the Cisco 12010, Cisco 12410, and Cisco 12810 Router consists of two clock and scheduler cards (CSCs) and five switch fabric cards (SFCs) installed in the switch fabric and alarm card cage. One CSC and four SFCs are required for an active switch fabric; the second CSC and the fifth SFC provide redundancy. Note Two alarm cards are also located in the switch fabric and alarm card cage. These cards are not a part of the switch fabric.
Switch Fabric Overview Note • Enhanced 10-Gbps switch fabric (200-Gbps switching system bandwidth) used in the Cisco 12410 Router—Consists of the 12410E-CSC and the 12410E-SFC fabric sets. Each SFC or CSC card provides a 10-Gbps full-duplex connection to each line card in the system. Thus, for a Cisco 12410 Router with 10 line cards with 2 x 10 Gbps (full duplex), the system switching bandwidth is 10 x 20 Gbps = 200 Gbps.
Alarm Card and Alarm Display Overview The SFC contains only the switch fabric circuitry, which carries user traffic between line cards or between the RP and the line cards. The SFC receives scheduling information and the system clock sent from the CSC. LEDs on the faceplate of the external alarm display card display the status of the cards in the switch fabric and alarm card cage.

Preparing for Installation • Do not work alone if potentially hazardous conditions exist. • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. • Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Preparing for Installation Preventing Electrostatic Discharge Damage Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as 30V, while static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures.

Removing and Installing a CSC or SFC Removing and Installing a CSC or SFC The switch fabric and alarm card cage is located below the line card and RP card cage, behind the air filter door on the front of the chassis. (See Figure 5.) The switch fabric and alarm card cage has seven keyed, vertical card slots for the clock and scheduler cards (CSCs) and switch fabric cards (SFCs).

Removing and Installing a CSC or SFC Installing a Card in the Switch Fabric and Alarm Card Cage To install a CSC or an SFC, follow these steps: Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD sockets on the front of the chassis or to a bare metal surface. (See Figure 4 on page 9.) Step 2 Remove the replacement card from its antistatic bag or ESD-preventive container.
Removing and Installing a CSC or SFC Caution All four sides of the air filter door are lined with EMI-preventive gaskets consisting of many raised, conductive contacts. Align and seat the door carefully to avoid damaging the EMI-preventive gasket contacts. A damaged gasket can result in reduced EMI performance. Step 2 Push firmly on the air filter door until it is seated in the opening of the switch fabric and alarm card cage, then tighten the two captive screws in each.
Removing and Installing the Alarm Card Removing and Installing the Alarm Card Procedures for removing and installing the alarm card are described in the following sections: • Upgrading the Mbus ROM, page 15 • Removing an Alarm Card, page 15 • Installing an Alarm Card, page 17 Note Caution One alarm card can be replaced while the system is running, but you must do this quickly because the normal cooling process is interrupted when the air filter door is open.

Removing and Installing the Alarm Card Step 3 Grasp the sides of the air filter door front cover and carefully pivot the door down, away from the switch fabric and alarm card cage (Figure 8). The alarm cards are the two right-most cards in the switch fabric and alarm card cage. They are labeled Alarm.
Removing and Installing the External Alarm Display Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both ejector levers might bind when you attempt to close the ejector levers, damaging or breaking one or both ejector levers. Step 6 Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the tabs on each side of the card cage slot.
Upgrading the Switch Fabric Installing the External Alarm Display To replace an external alarm display assembly, follow these steps: Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD sockets on the front of the chassis or to a bare metal surface (see Figure 4 on page 9). Step 2 Secure the replacement external alarm display assembly to the chassis with the two panel screws.
Upgrading the Switch Fabric Upgrade Requirements Before proceeding, review the following upgrade requirements: 1. You must have a complete switch fabric card set. You cannot intermix 2.5-, 10-, and 40-Gbps CSCs and SFCs. 2. When upgrading to a 10-Gbps switch fabric with a GRP installed, the Flash memory card must be loaded with Cisco IOS Release 12.0(16)S or later. 3. When upgrading to a 10-Gbps switch fabric with a PRP installed, the Flash memory card must be loaded with Cisco IOS Release 12.
Upgrading the Switch Fabric Step 10 Note See the next section, Verifying the Upgrade. Additional information is available on the Cisco TAC website. Refer to the Cisco 12000 Series Internet Router Upgrade Procedure document. Verifying the Upgrade To verify that the upgraded switch fabric is operating properly, follow these steps: Step 1 Perform all the steps listed in the “Upgrading the Switch Fabric” section on page 19.
Troubleshooting the Switch Fabric Post-Upgrade Considerations After performing an upgrade and verifying its installation, there are some post-upgrade considerations. • Cisco 12000 Series routers include a label on the side of the chassis that indicates the model of the router. The switch fabric upgrade kit does not include a new label to identify the upgraded router model.
Troubleshooting the Switch Fabric Step 5 Gather the output and proceed to the Analyzing the Data section. Analyzing the Data Switch fabric problems can occur due to failures in any of the following components: • RP • Line card hardware • Backplane • CSCs/SFCs When troubleshooting switch fabric errors, you need to look for patterns with regard to which components are reporting errors.
Troubleshooting the Switch Fabric In the sample output below, you can see the status of the line card in slot 2. The crc16 data line is underlined and is showing errors from sfc1. Remember to use the attach command (not the execute-on command) to access the line cards.
Troubleshooting the Switch Fabric This table indicates that more than one line card is reporting errors coming from SFC 1. Therefore, the first step is to change this SFC. Each time a replacement is recommended, first verify that the card is correctly seated. You should always reseat the corresponding card to ensure it is correctly seated. If, after reseating the card, the CRCs still increase, then replace the part. See the “Properly Seating Switch Fabric Cards” section on page 26.

Grant errors on more than one line card: a. Replace the CSC (see the note below to know which one should be swapped) b. Replace the backplane 2. Grant errors on one line card: a. Replace the line card a.
