Installing and Removing ModulesThis chapter describes how to install and remove modules in the switch router and includes the following sections:
Safety RecommendationsThe port adapters, interface modules, and redundant (second) route processors, switch processors, and power supplies are designed for removal and replacement while the system is operating without presenting an electrical hazard or causing damage to the system. Read the Site Preparation and Safety Guide, and follow these guidelines when working with any electrical equipment:
Guidelines for Installing and Removing ModulesThis section describes how to use the release levers and captive installation screws to properly install and remove the modules in the system chassis. This section also includes a list of the tools required for module installation and removal. Release levers and captive installation screws align and seat the module connectors in the backplane. (See Figure 2-1.) Figure 2-1: Release Levers and Captive Installation Screws
Follow the installation and removal instructions carefully, paying special attention to the following practices:
Hot SwappingPort adapters, carrier modules, and interface modules support hot swapping, so you can install, remove, and rearrange these modules without turning off the system power. When the system detects that a port adapter, carrier module, interface module, or switch processor is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the module, and resumes system operation without any operator intervention.
When you remove and replace modules, the system provides status messages on the console screen. These messages are for information only. In the following sample displays, you can follow the events logged by the system when a Layer 3 interface module is removed from slot 3 in a Catalyst 8540 CSR. When the interface module is reinserted, the system marks the module as ready again. Catalyst 8540 CSR Router# %OIR-6-REMCARD: Card removed from slot 3/0/0, interfaces disabled %LINK-5-CHANGED: Interface 3/0/0, changed state to administratively down %LINK-5-CHANGED: Interface 3/0/0, changed state to administratively down Router# %OIR-6-INSCARD: Card inserted in slot 3/0, interfaces administratively shut down %LINK-5-CHANGED: Interface 3/0/0, changed state to up %LINK-5-CHANGED: Interface 3/0/0, changed state to up Router# Tools RequiredYou need the following tools and equipment to install port adapters, carrier modules, interface modules, and switch processors in the chassis:
Installing and Removing Port AdaptersThis section describes how to install and remove port adapters. You can install up to two half-width port adapters onto one carrier module, which can then be installed in one slot of an ATM switch router. Table 1-2 lists slot assignments for port adapters. Also see Figure 1-5 and Figure 1-6. See the "Installing and Removing Modules" section for more information about carrier modules. Installing Port Adapters
To install a port adapter in a carrier module, follow these steps: Step 1 Choose a port adapter slot in a carrier module and ensure that there is enough clearance to accommodate any interface equipment that you connect directly to the port adapter. (See Figure 2-2A.) If possible, place port adapters between empty slots that contain only port adapter filler plates. Step 2 Place the back of the port adapter in the slot and align the notch on the sides of the module carrier with the groove in the slot. (See Figure 2-2B.) Step 3 Hold both sides of the port adapter and guide it into the slot. Avoid touching the port adapter components. Figure 2-2: Installing a Port Adapter in a Carrier Module
Step 4 Keep the port adapter at a 90-degree orientation to the backplane and carefully slide the port adapter into the slot until the faceplate makes contact with the carrier module faceplate. Step 5 Use a 3/16-inch flat-blade screwdriver to tighten the captive installation screw in the center of the port adapter faceplate. Draw the port adapter into the carrier module connector until the port adapter faceplate is flush with the carrier module faceplate and the carrier module is fully seated in the connector. Step 6 Attach network interface cables or other devices to the interface ports.
Step 7 Use the show interfaces command to check the status of the interfaces. If this installation is a replacement interface module, use the show configuration or show interface atm [card/subcard/port] command to verify that the system acknowledged the new interfaces and brought them up. Refer to your software publications for complete software configuration and command syntax information. Removing Port Adapters
To remove a port adapter from a carrier module, follow these steps: Step 1 Disconnect all network interface cables from the port adapter.
Step 2 Use a 3/16-inch flat-blade screwdriver to loosen the captive installation screw in the center of the port adapter. As you loosen the captive installation screw in the port adapter, it disengages from the carrier module interface at the rear of the module. (See Figure 2-3A.) Step 3 Pull the port adapter straight out of the carrier module slot carefully, keeping your other hand under the carrier to guide it. Keep the module at a 90-degree orientation to the backplane. (See Figure 2-3B.) Step 4 Store the port adapter in an antistatic bag or immediately install it in another carrier module. Figure 2-3: Removing a Port Adapter
Installing and Removing ModulesThis section describes how to install and remove route processors, switch processors, carrier modules, and interface modules in the switch router. For slot assignments for modules, see Table 1-2, Figure 1-5 on page 1-11, and Figure 1-6 on page 1-12.
Installing Modules
To install a route processor, switch processor, carrier module, or interface module, follow these steps: Step 1 Ensure that there is enough clearance to accommodate any interface equipment that you connect directly to the module ports. If possible, install modules between empty slots that contain only module filler plates. Step 2 Hold the module faceplate with one hand, and place your other hand under the carrier and guide it into the slot. Avoid touching the module components. (See Figure 2-4A.) Step 3 Place the back of the module in the slot and align the notch on each side of the carrier module with the groove in the slot. (See Figure 2-4B.) Step 4 Keep the module at a 90-degree orientation to the backplane and carefully slide it into the slot until the faceplate makes contact with the release levers. Step 5 Use the thumb and forefinger of each hand to simultaneously push the left lever and the right lever in until the carrier module is fully seated in the backplane connector. (See Figure 2-4C.)
Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the captive installation screws on the left and right ends of the module. (See Figure 2-4D.)
Step 7 Attach network interface cables or other devices to the interface ports.
Step 8 Turn the power on. Refer to your hardware installation poster or the Catalyst 5000 Family Installation Guide. Step 9 Verify that the system has acknowledged the new interface and has brought it up, as follows:
Refer to your software publications for complete software configuration and command syntax information. Figure 2-4: Installing a Route Processor, Switch Processor, Carrier Module, or Interface Module
Removing ModulesTo remove route processors, switch processors, carrier modules, or interface modules, follow these steps: Step 1 Disconnect all network interface cables from the module that will be removed.
Step 2 Loosen the captive installation screws on the left and right sides of the module with a flat-blade screwdriver. (See Figure 2-5A.)
Step 3 Place your thumbs on the left and right release levers and simultaneously push the left lever left and the right lever right to release the carrier module from the backplane connector. (See Figure 2-5B.) Step 4 Grasp the faceplate with one hand and place your other hand under the module to support and guide the module out of the slot. Avoid touching the card. (See Figure 2-5C.) Step 5 Pull the module straight out of the slot carefully, keeping your other hand under the module to guide it. Keep the module at a 90-degree orientation to the backplane. (See Figure 2-5C.) Step 6 Place the removed module on an antistatic mat or antistatic foam, or immediately install it in another slot. Step 7 Install a filler plate to keep dust out of the chassis and to maintain proper airflow through the module compartment if the slot will remain empty.

Installing and Removing Flash Memory SIMMsThe Flash memory single in-line memory module (SIMM) stores the system and microcode images. The default Flash memory configuration is 16 MB. The size of the system image and the cumulative size of any additional files stored in Flash memory determine the amount of Flash memory required on the route processor. When purchasing a new Flash memory SIMM, make sure it meets the following specifications:
Parts and Tools RequiredYou need the following parts and tools:
Installing Flash Memory SIMMsFollow these steps to install a Flash memory SIMM: Step 1 Place the route processor so that the edge connector is facing away from you and the faceplate is towards you. Step 2 Remove the new Flash memory SIMM from its antistatic bag. Step 3 Hold the SIMM component side up with the connector edge (the edge with metal fingers) facing downward (see Figure 2-6).
Figure 2-6: Handling the Flash Memory SIMM
Step 4 Make sure the polarization notch is at the right side (see Figure 2-7). Insert the new Flash memory SIMM by sliding the end with the metal fingers into the SIMM socket at a slight angle. Figure 2-7: Inserting the Flash Memory SIMM
Step 5 Rotate the SIMM gently down into place until the spring clips on both sides snap into place. (See Figure 2-8.) Figure 2-8: Securing the Flash Memory SIMM in a SIMM Socket
Step 6 Reinstall the route processor in the chassis. (For more information, see the "Installing and Removing Modules" section.) Step 7 Use a flat-blade screwdriver to tighten the captive installation screws at the left and right sides of the route processor. Step 8 Turn on the system. If the chassis fails to boot properly, or if the console terminal displays a checksum or memory error, make sure that:
If after several attempts the chassis fails to restart properly, contact a customer service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve Removing Flash Memory SIMMsFollow these steps to remove the current Flash memory SIMM: Step 1 Enter the copy flash tftp EXEC command to back up the system image if you are storing the system image on the internal Flash memory SIMM. The system image is lost when you replace the SIMM with another one. If you are storing the system image on a Flash PC Card in Flash PC Card slot 0 or 1, skip this step and proceed to the next step. Step 2 Turn off the chassis, but to channel ESD voltages to ground, do not disconnect the power cable.
Step 3 Attach an ESD-preventive wrist strap to your wrist and the ESD strap connection at the bottom of the chassis. Step 4 Disconnect all cables from the route processor. Step 5 Use a flat-blade screwdriver to loosen the captive installation screws at the left and right sides of the route processor. Slide it out of the chassis. For more information, see the "Installing and Removing Modules" section. Step 6 Place the route processor on an antistatic mat or bag. Step 7 Position the route processor so that the edge connector is away from you and the faceplate is toward you. (See Figure 2-9.) Step 8 Locate the Flash memory SIMM at the front right corner of the route processor. (See Figure 2-9.) Figure 2-9: Locating the Flash Memory SIMM
Step 9 Place your index fingers on the sides of the SIMM socket and your thumbs on the spring clips, as shown in Figure 2-10. Step 10 Press outward on the spring clips with your thumbs to release the Flash memory SIMM from the SIMM socket. (See Figure 2-10.) Figure 2-10: Releasing the Flash Memory SIMM
Step 11 Tilt the Flash memory SIMM upward and remove it from the SIMM socket. Step 12 Place the Flash memory SIMM in an antistatic bag to protect it from ESD damage. Step 13 Restore any files you copied to a TFTP server earlier by entering the copy tftp flash privileged EXEC command. Installing and Removing Flash PC CardsThis section describes how to install and remove a Flash PC Card. Flash PC Cards ship either installed in a route processor or as a spare part. When the Flash PC Card is shipped installed in a route processor, the card contains a system image. A spare card ships unformatted; you must format the card before you can use it. Refer to your software configuration guide for fomatting instructions. The route processor includes two Flash PC Card slotsslot 0 and slot 1that accept 8-MB, 16-MB, or 20-MB Series 2+ Flash PC Cards. The Flash PC Card stores the system image and can also store software and microcode images for other systems.
Installing a Flash PC CardFollow these steps to install a Flash PC Card: Step 1 Face the front panel of the route processor (see Figure 2-11) and hold the Flash PC Card with the connector end of the card toward the slot. The label on the Flash PC Card should face up. (See Figure 2-11A.) Step 2 Insert the card into the slot until the card is completely seated in the connector at the back of the slot and the eject button pops out toward you. (See Figure 2-11B.) Do not attempt to force the card past this point.
Removing a Flash PC CardFollow these steps to remove a Flash PC Card: Step 1 Press the eject button until the card is free of the connector at the back of the slot. (See Figure 2-11C.) Step 2 Remove the card from the slot and place it in an antistatic bag to protect it from ESD damage. Figure 2-11: Installing and Removing the Flash PC Card
Guidelines for Installing and Removing GBICsA Gigabit Interface Converter (GBIC) is a hot-swappable input/output transceiver that plugs into the interface module, enabling the module to link with a Gigabit Ethernet network using fiber-optic cable. (See Figure 2-12.) The following GBIC types are supported:
Figure 2-12: Gigabit Interface Converter
Follow these guidelines to ensure the performance of your GBIC:
Figure 2-13: GBIC Optical Bore and Ferrule
Patch CordWhen using the 1000BaseLX/LH GBIC with 62.5-micron diameter multimode fiber (MMF), you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. You need the patch cord for link distances greater than 984 feet (300 meters). For link spans less than 300 meters, you can omit the patch cord. The patch cord must comply with IEEE standards. The IEEE found that link distances did not meet with certain types of fiber-optic cable because of a problem in the center of some fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center by using the patch cord. At the output of the patch cord, the 1000BaseLX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BaseLX. For a detailed description of this problem, refer to the "Differential Mode Delay" section.
Plug the end of the patch cord labeled "To equipment" into the GBIC. (See Figure 2-14.) Plug the end labeled "To cable plant" into the patch panel. The patch cord is 9.84 feet (3 meters) long and has duplex SC-type male connectors at each end. Figure 2-14: Installing the Patch Cord
Differential Mode DelayWhen an unconditioned laser source (1000BaseLX/LH GBIC) designed for operation on single-mode fiber (SMF) cable is directly coupled to an MMF cable, differential mode delay (DMD) can occur. DMD can degrade the modal bandwidth of the fiber-optic cable causing a decrease in the link span (the distance between the transmitter and the receiver) that is reliably supported. The Gigabit Ethernet specification (IEEE 802.3z) outlines parameters for Ethernet communications at a gigabits per second rate. The specification offers a higher speed version of Ethernet for backbone and server connectivity using existing deployed MMF cable. To accomplish this, the specification defines the use of laser-based optical components to propagate data over MMF cable. Lasers function at the baud rates and longer distances required for Gigabit Ethernet. The IEEE 802.3z Gigabit Ethernet Task Force has identified the DMD condition that occurs in certain circumstances with particular combinations of lasers and MMF cable. The resulting characteristics create an additional element of "jitter" that limits the reach of Gigabit Ethernet over MMF cable. With DMD, a single laser light pulse excites a few modes equally within an MMF cable. These modes, or light pathways, then follow two or more different paths. These paths may be of different lengths and have different transmission delays as the light travels through the cable. With DMD, a distinct pulse propagating down the cable no longer remains a distinct pulse or, in extreme cases, can become two independent pulses. Strings of pulses tend to interfere with each other making it difficult to recover data in a reliable fashion. DMD does not occur in all deployed fibers. It occurs with certain combinations of worst-case fibers and worst-case transceivers. Gigabit Ethernet is the first technology to experience this problem because of its very high baud rate and its long MMF cable lengths. SMF cable and copper cable are not affected by DMD. MMF cable has only been tested for use with LED sources. LEDs create a condition within a fiber-optic cable referred to as an overfilled launch condition. The overfilled launch condition describes the way LED transmitters couple light into the fiber-optic cable in a broad spread of modes. Similar to a light bulb radiating light into a dark room, the generated light shines in multiple directions that "overfill" the existing cable space and "excites" a large number of modes. (See Figure 2-15). Figure 2-15: LED Transmission Compared to Laser Transmission
Lasers launch light in a more concentrated fashion. Typically, a laser transmitter couples light into only a fraction of the existing modes or optical pathways in the fiber-optic cable. (See Figure 2-15.) The solution to DMD is to condition the laser light launched from the source (transmitter) so it spreads the light evenly across the diameter of the fiber-optic cable making the launch look more like an LED source to the cable. The objective is to scramble the modes of light to distribute the power more equally in all modes. This prevents the light from being concentrated in just a few modes. This is in contrast to an unconditioned launch, which, in the worst case, might concentrate all of its light in the center of the fiber-optic cable, thereby exciting only two or more modes equally. A significant variation in the amount of DMD is produced from one MMF cable to the next. No reasonable test can be performed to survey an installed cable plant to assess the effect of DMD. Therefore, you must use the mode-conditioning patch cords for all 1000BASE-LX/LH GBICs using MMF when the link span exceeds 984 feet (300 meters). For link spans less than 300 meters, you can omit the patch cord. Installing and Removing GBICsThis section describes how to install and remove a Gigabit Interface Converter (GBIC) in the Gigabit Ethernet interface modules. The Gigabit Ethernet modules ship without GBICs installed. GBICs are hot-swappable in the Gigabit Ethernet modules. Installing GBICsTo install a GBIC, follow these steps: Step 1 Remove the GBIC from its protective packaging. Step 2 Verify that the GBIC is the correct type for your network by checking the part number. The number indicates whether it is 1000BASE-SX, 1000BASE-LX, or 1000BASE-ZX. Step 3 If you are installing the GBIC into a two-port enhanced Gigabit Ethernet interface module or a two-port Gigabit Ethernet interface module with built-in ACL functionality, turn the GBIC so that the cable slots are facing up, and insert the GBIC into the interface module. For all other interface modules, make sure that the GBIC cable slots are facing down and insert the GBIC into the interface module. (See Figure 2-16.) Figure 2-16: GBIC Cable Slots
Step 4 Slide the GBIC into the slot until you hear a click. The click indicates the GBIC module is locked into the slot. (See Figure 2-17.) Figure 2-17: Installing a GBIC Module
Step 5 Remove the plug from the GBIC and save it for future use. (See Figure 2-17.) Step 6 Attach the fiber-optic cable. Removing GBICsTo remove a GBIC, follow these steps: Step 1 Disconnect the fiber-optic cable from the GBIC SC-type connector. Step 2 Release the GBIC from the slot by simultaneously squeezing the plastic tabs (one on each side of the GBIC). Step 3 Slide the GBIC out of the slot. Step 4 Install the plugs in the GBIC optical bores, and place the GBIC in protective packaging. Installing and Removing an ACL Daughter CardThis section describes how to install and remove an access control list (ACL) daughter card onto an interface module. You can install the ACL daughter card on the following interface modules:
Parts and Tools RequiredTo install or remove an ACL daughter card, you need the following parts and tools:
Installing an ACL Daughter CardTo install an ACL daughter card onto an interface module, follow these steps: Step 1 Remove the interface module from the chassis. See the "Removing Modules" section for instructions. Step 2 Place the interface module on an antistatic mat or bag. Step 3 Remove the M3x.5 screws on the interface module and replace them with the 12-mm mounting standoffs. (See Figure 2-18 for the Catalyst 8540 CSR. For the Catalyst 8510 CSR, see Figure 2-19.) Use the 1/4-inch socket driver to install the 12-mm mounting standoffs. Figure 2-18: Removing the Screws from the Catalyst 8540 CSR Interface Module

Step 6 Remove the mounting standoffs and save them for future use. Step 7 Store the ACL daughter card in an antistatic bag. Step 8 Reinstall the interface module in the chassis or install a new ACL daughter card. See the "Installing and Removing Modules" section or the "Installing an ACL Daughter Card" section for further information. Figure 2-29: Removing an ACL Daughter Card (Catalyst 8510 CSR)
Confirming the InstallationProblems with the initial startup are often caused by a module or power supply that has become dislodged from the backplane or chassis power connector. Although over-temperature conditions rarely occur at initial startup, the environmental monitoring functions are included because they also monitor DC line interface voltages. At the initial system boot, verify the following:
When these conditions are met, the hardware installation is complete. If the startup sequence fails before these conditions are met, use these procedures to isolate and, if possible, resolve the problem. If you are unable to solve a problem, contact a customer service representative for assistance and further instructions. Before you call, gather the following information:
