Installing and Connecting Components

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Ensuring Safety with Electricity

The line modules and redundant (second) power supplies are designed for removal and replacement while the system is operating without presenting an electrical hazard or causing damage to the system.

Follow these guidelines when working with any electrical equipment:

Never install equipment that appears to be damaged.
Do not begin any procedures requiring access to the chassis interior before locating the emergency off switch for the room in which you are working.
Do not work alone when potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Do not begin any procedure before carefully examining your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

In addition, use the guidelines that follow when working with any equipment that is disconnected from a power source but still connected to telephone wiring or other
network cabling.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Use caution when installing or modifying telephone lines.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The route processor and line modules each consist of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use a preventive antistatic strap whenever you handle the route processor or line modules. Handle the modules by the edges only; never touch the cards or connector pins.

Caution Always tighten the captive installation screws on the route processor and line modules when you are installing them. These screws prevent accidental removal of the route processor and line modules, provide proper grounding for the system, and help to ensure that the bus connectors are properly seated in the backplane.

Follow these guidelines for preventing ESD damage:

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

Always handle modules by the faceplates and carrier edges only; avoid touching the card or any connector pins.

Always connect the equipment end of the strap to a grounding screw before removing any module. (See Figure 2-1.)

Figure 2-1: Placement of Electrostatic Discharge Wrist Strap

Always place the removed module with the components facing up on an antistatic surface or in a static shielding bag. If the module is to be returned to the factory, immediately place it in a static shielding bag.
Always avoid contact between the modules and clothing. The wrist strap protects only the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.

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

Preparing Network Connections

When preparing your site for network connections to the Catalyst 8540 device, consider these factors for each type of interface:

Cabling required for each type (fiber-optic or unshielded twisted-pair (UTP) cabling)
Distance limitations for each signal type
Additional interface equipment needed

Before installing the component, have all additional external equipment and cables on hand.

The UTP port on the Catalyst 8540 CSR 10/100BaseT Ethernet line module is an RJ-45 receptacle. If you intend to build your own cables, refer to Table B-1 in the appendix "Cable and Port Pinouts" for a list of the RJ-45 cable connector pinouts.

Distance Limitations

The length of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission media (the type of cabling used to transmit the signals). For example, fiber-optic cable has a greater channel capacity than UTP cabling.

Note The distances and rate limits in this chapter are the IEEE-recommended maximum speeds and distances for signaling. However, you can get good results at speeds and distances far greater than these if you understand the electrical problems that might arise and can compensate for them. However, do so at your own risk.

The following distance limits are provided as guidelines for planning your network connections before installation.

The maximum distances for network segments and connections depend on the type of transmission cable used, for example, UTP or multimode fiber-optic cable.

Networking standards set recommended maximum distances between stations using fiber-optic and UTP cable. The recommended maximum cable lengths are listed in Table 2-1.

Table 2-1: Maximum Transmission Distances

1000 Mbps	Multimode fiber	1640 ft (500 m)
1000 Mbps	Single mode fiber	16404 ft (5000 m)

Connection Equipment

All Catalyst 8540 interfaces can support full-duplex or half-duplex connections. You must use the appropriate interface cable to connect the multimode or UTP ports with an external network.

For 10-Mbps or 100-Mbps UTP traffic, use the RJ-45 connector (see Figure 2-2) to connect the line modules with the external switch.

Figure 2-2: RJ-45 Interface Cable Connector

For 100-Mbps fiber-optic traffic, use the MT-RJ connector to connect the line modules with the external connection. The fiber-optic connector (MT-RJ type) is shown in Figure 2-3.

Figure 2-3: Fiber-Optic Network Interface Connector (MT-RJ Type)

For 1000-Mbps fiber-optic traffic, use the SC-type connector to connect the Gigabit Ethernet line modules with the external connection. This connector is shown in Figure 2-4.

Figure 2-4: SC-Type Fiber-Optic Network Interface Connector

Installing the Route Processor or Switch Module

This section describes how to install a route processor or switch module in the Catalyst 8540 chassis.

Note The route processor ships installed in the Catalyst 8540 chassis, unless you order it as a spare or as part of an upgrade kit. To remove an existing route processor, refer to the chapter "Replacing Components."

The Catalyst 8540 chassis has 13 slots. Slots 4 through 8 are reserved for the route processor and switch modules, as shown in Figure 2-5.

Caution Make sure blank slot fillers cover all unused slots to ensure proper airflow within the chassis.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Figure 2-5: Route Processor and Switch Module Slot Numbers

To install the route processor or switch module, 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.

Step 1 Power off the device, but to channel ESD voltages to ground, do not disconnect the power cable.

Caution The route processor and switch modules are required system components. Removing or installing a route processor or switch module while the Catalyst 8540 CSR is operating causes the system to shut down and might damage the processor. Power down the Catalyst 8540 CSR before removing or installing a route processor or switch module.

Step 2 Hold the route processor or switch module faceplate with one hand, and place your other hand under the processor card. Avoid touching the components on top of the card. (See Figure 2-6.)

Caution Handle the route processor or switch module only by the edges to prevent ESD damage.

Figure 2-6: Route Processor Installation

Step 3 Align the route processor or switch module with the rails on the inside of the chassis.

Step 4 Carefully slide the route processor or switch module into the appropriate slot (slot 4 for the route processor or slot 5 or 7 for the switch module) until the route processor or switch module stops and the release levers are protruding outward.

Step 5 Put your thumbs on the left and right release levers and simultaneously push inward on the levers to seat the route processor or switch module in the backplane connector.

Caution Always use the ejector levers when installing or removing the route processor or switch module. A processor or module partially seated in the backplane can cause the system to halt and subsequently crash.

Step 6 Use a flat-blade screwdriver to tighten the captive installation screws on the left and right sides of the route processor or switch module.

Step 7 Attach network interface cables or other devices to the interface ports.

Step 8 Power up the device.

To check the installation, enter the show hardware privileged EXEC command to verify that the system has acknowledged and brought up the new interfaces.

Connecting the Route Processor to a Network

This section describes how to connect the route processor to a network.

Before connecting the route processor to a network, consider the following:

Type of cable required for each interface:
- Straight-through Ethernet for the 10BaseT RJ-45 Ethernet port

Note

Straight-through EIA/TIA-232 for the console port

Distance limitations for each signal type
Any additional interface equipment you need

Before making the connections, have all additional external equipment and cables on hand. For ordering information, contact a customer service representative. To build your own cables, refer to the cable pinouts in the appendix "Cable and Port Pinouts."

Ethernet Port Connections

Use a straight-through Ethernet cable with RJ-45 male connectors (see Figure 2-7) to connect between the Ethernet port and an Ethernet network. Table B-1 in the appendix "Cable and Port Pinouts" lists the Ethernet cable connector pinouts.

Figure 2-7: RJ-45 Ethernet Cable Connector

Console Port Connections

The route processor includes an EIA/TIA-232, data communications equipment (DCE) console port (see Figure 2-8). This port provides access to the device either remotely (with a DTE device) or locally (with a console terminal). This section describes important cabling information to consider before connecting a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port.

Figure 2-8: Console Port

EIA/TIA-232 supports unbalanced circuits at signal speeds of up to 64 kbps. Figure 2-9 shows the connectors at the network end of the adapter cable for DCE and DTE connections.

Figure 2-9: EIA/TIA-232 Adapter Cable Connectors, Network End

The console port on the route processor is a female, EIA/TIA-232, DCE, DB-25 receptacle. Both data set ready (DSR) and data carrier detect (DCD) activate when the system is running. The Ready To Send (RTS) signal tracks the state of the Clear To Send (CTS) input. The console port does not support modem control or hardware flow control. The console port requires a straight-through EIA/TIA-232 cable. Table B-2 in the appendix "Cable and Port Pinouts" lists the signals used on this port.

Note The console port is an asynchronous serial port; any devices connected to this port must be capable of asynchronous transmission. (Asynchronous devices are the most common type of serial device.)

Before connecting to the console port, check your terminal's documentation to determine the baud rate. The baud rate of the terminal must match the default baud rate (9600 baud) of the port you use. Set up the terminal as follows:

9600 baud
8 data bits
No parity
1 stop bit

Installing and Removing Flash Memory Cards

This section describes how to install and remove Flash memory cards. Flash memory cards ship either installed in a device or as a spare part. When the Flash memory card is shipped installed in a device, the card contains a system image. When the card is shipped as a spare part, it is unformatted; you must format the card before you use it.

Note For formatting instructions, refer to the Catalyst 8540 Software Feature and Configuration Guide.

The route processor includes two Flash PC card slots--slot 0 and slot 1--that accept 8-MB, 16-MB, or 20-MB Series 2+ Flash memory cards. The Flash memory card stores the system image and can also store software and microcode images for other systems.

Note You can install or remove a Flash memory card with the power on.

To install and remove a Flash memory card, follow these steps:

Step 1 Face the front panel of the route processor (see Figure 2-10) and hold the Flash memory card with the connector end of the card toward the slot. The label on the Flash memory card should face up (see Figure 2-10a).

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 2-10b). Note that the card does not insert all the way inside the route processor; a portion of the card remains outside of the slot.

Caution Do not attempt to force the card past this point.

Note

Figure 2-10: Installing and Removing the Flash Memory Card

Step 3 To eject the card, press the EJECT button until the card is free of the connector at the back of the slot. (See Figure 2-10c.)

Step 4 Remove the card from the slot and place it in an antistatic bag to protect it from ESD damage.

This concludes the procedure for installing and removing Flash memory cards. Consult the Catalyst 8540 Campus Switch Router Software Feature and Configuration Guide for configuration instructions.

Removing and Installing Line Modules

All line modules support hot swapping, which means you can install, remove, replace, and rearrange the line modules without turning off the power for the Catalyst 8540 CSR. When the system detects that a line module is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the line module, and resumes system operation without any operator intervention.

Caution Although line modules support hot swapping, the route processor and switch modules do not. The route processor and switch modules are required system components, and removing any of them while the device is operating causes the system to shut down and can damage the processor.

Sample Console Display for Hot-Swapping Procedure

When you remove and replace line modules, the system provides status messages on the console screen. The messages are for information only. In the following sample display, you can follow the events logged by the system when a line module is removed from slot 3. When the line module is reinserted, the system marks the module as ready again.

Line Module Installation Guidelines

The release levers and captive installation screws (see Figure 2-11) align and seat the module connectors in the backplane.

Figure 2-11: Release Levers and Captive Installation Screws

Follow the installation and removal instructions carefully, paying special attention to the following practices:

Use the release levers and captive installation screws to guide the line module into the slot. Using the faceplate to force or slam the module can damage the pins on the module connectors.
Use the release levers or captive installation screws to seat the line module in the backplane. This ensures that the module connector mates with the backplane correctly. If you use the faceplate, the line module might seat improperly.
Use the release levers and captive installation screws to insert a line module, and be sure to push the release levers to the full 90-degree position. If you use the faceplate or leave the levers in the wrong position, some of the connector pins might mate to the backplane, which suspends the system.
Insert the line module firmly to ensure that all three layers of pins mate with the backplane. Inserting the module too slowly (for example, leaving a component partially inserted) could cause the system software to time out and fail to recognize the installed component. If that happens, disconnect and reinsert the line module.

To ensure that the module connector pins disconnect from the backplane in the sequence expected by the system, use the release levers and captive installation screws to remove a line module. Any line module that is only partially connected to the backplane will halt the system.

You need a 3/16-inch flat-blade screwdriver to remove any filler line modules and to tighten the captive installation screws that secure the line modules in their slots. Whenever you handle line modules, you should use a wrist strap or other grounding device to prevent ESD damage. See the section "Preventing Electrostatic Discharge Damage."

The following section contains detailed steps for removing and replacing line modules and successfully performing hot swapping.

Removing Line Modules

This section explains the procedures for removing line modules.

Note A line module is a hot-swappable device. It can be removed or installed in a running chassis. The Catalyst 8540 device automatically recognizes the line module and its interfaces.

Follow these steps to remove a line module:

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.

Step 1 Disconnect all cables from the line module that is to be removed.

Caution Failure to disconnect cables could damage the line module.

Step 2 Loosen the captive installation screws at the left and right sides of the line module with a screwdriver.

Step 3 Place your thumbs on the left and right release levers and simultaneously push the left lever to the left and the right lever to the right to release the line module from the backplane connector.

Step 4 Grasp the line module 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 module components.

Step 5 Pull the line module straight out of the slot carefully, placing one hand under the module to guide it. Keep the module at a 90-degree orientation to the backplane.

Step 6 Place the removed line module on an antistatic mat or antistatic foam, or immediately install it in another slot.

Step 7 If the line module slot is to remain empty, install a module filler plate to keep dust out of the chassis and maintain proper airflow through the module compartment.

Installing Line Modules

You can install line modules in any of the eight line module slots 0 through 3 and 9 through 12 from top to bottom when viewing the chassis from the front. (See Figure 2-12.) Slots 4 through 8 are reserved for the route processor and switch modules, which are required system components. Install blank line module filler plates in empty slots to maintain consistent airflow through the module compartment.

Figure 2-12: Line Module Slot Numbers

Follow these steps to install a line module. All line modules support hot swapping and can be removed or installed while the system is operating.

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.

Caution To prevent ESD damage, handle the line module by the edges only.

Step 1 Ensure that there is enough clearance to accommodate any interface equipment that you connect to the line module ports. If possible, install line modules next to empty slots that contain only module filler plates.

Step 2 Use a 1/4-inch flat-blade screwdriver to loosen the captive installation screws and remove the line module filler plate (or the existing line module) from the slot you want to use.

Step 3 Hold the line module faceplate with one hand, and place your other hand under the module and guide it into the slot. Avoid touching the module components. (See Figure 2-13.)

Figure 2-13: Line Module Installation

Step 4 Place the back of the line module in the slot and align the notch on each side of the module with the groove in the slot.

Step 5 Keep the line module at a 90-degree orientation to the backplane; carefully slide it into the slot until the faceplate makes contact with the release levers.

Step 6 Use the thumb and forefinger of each hand to simultaneously push the left lever and the right lever in until the line module is fully seated in the backplane connector.

Caution Always use the release levers when installing or removing the line module. Leaving a line module only partially seated in the backplane causes the system to halt and subsequently crash.

Step 7 Use a screwdriver to tighten the captive installation screws on the left and right ends of the line module.

Step 8 Attach network interface cables or other devices to the interface ports.

Step 9 Check the status of the interfaces as follows:

If this installation is a replacement line module, enter the show configuration or show interface [slot_num/mod_num/port_num] command to verify that the system has acknowledged the new interfaces and has brought them up.
See the Catalyst 8540 Campus Switch Router Software Feature and Configuration Guide for all software instructions and information.

Catalyst 8540 Port Addresses

Each interface (or port) in the Catalyst 8540 CSR is designated by several different types of addresses. The physical interface address is the actual physical location (module/submodule/port) of the interface connector within the chassis. The system software uses the physical addresses to control activity within the device and to display status information. These physical module/submodule/port addresses are not used by other devices in the network; they are specific to the individual device and its internal components and software.

The following sections describe how the Catalyst 8540 CSR assigns and controls both the physical (module/submodule/port) and Media Access Control (MAC)-layer addresses for interfaces within the chassis.

Port IDs

The Catalyst 8540 CSR device port IDs specify the actual physical location of each line module port on the front of the chassis. (See Figure 2-14.) The address is composed of a three-part number in the format module/submodule/port.

The first number identifies the slot in which the module is installed. Module slots are numbered 0 to 12 from top to bottom, with slots 0 through 3 and 9 through 12 available for use. The second number identifies the submodule or line module number. For this device, this number is always 0, as there can only be one line module per slot. The third number identifies the physical port number on the line module. The port numbers always begin at 0 and are numbered from the left port to the right port, facing the front of the chassis. The number of additional ports (/1, /2, and so on) depends on the number of ports available on the module.

Figure 2-14: Port ID Address Examples

Interface ports maintain the same port ID regardless of whether other modules are installed or removed. However, when you move a module to a different slot, the first number in the address changes to reflect the new slot number.

For example, on a 16-port 10/100 UTP line module in chassis slot 1, the address of the left port is 1/0/0 and the address of the right port is 1/0/15. If you remove the line module from slot 1 and install it in slot 3, the addresses become 3/0/0 and 3/0/15.

You can identify module ports by physically checking the module/submodule/port location on the front of the chassis. You can also use software commands to display information about a specific interface, or all interfaces, in the device. To display information about every interface, enter the show interface command without parameters. To display information about a specific interface, enter the show interface command with the interface type and port address in the format show interface ethernet module/submodule/port.

Line Module Configuration

The line modules support different media and interface types. The configuration commands used with these different line modules vary according to line module type. For complete line module configuration information, refer to the Catalyst 8500 Campus Switch Router Software Feature and Configuration Guide.

Cabling the Line Modules

This section describes cabling for the Catalyst 8540 CSR line modules. When your Catalyst 8540 CSR leaves the factory, it is configured as specified in your order and is ready for installation and startup. As your communication requirements change, you might want to upgrade your system, add components, or change the initial configuration.

The following line modules are described in this section:

10/100BaseT Ethernet (16 UTP ports)
100BaseFX Ethernet (16 fiber ports)
Gigabit Ethernet (2 fiber ports)

Software and upgrades require specific document part numbers and other frequently updated information. Detailed instructions are included in the Catalyst 8500 Campus Switch Router Software Feature and Configuration Guide.

All Catalyst 8540 interfaces are bidirectional. You must use the appropriate interface cable to connect a line module interface to an external network.

This section shows the required connection equipment and line module network connections and LEDs.

The Catalyst 8540 line modules can support interfaces that connect to Layer 2 or Layer 3. (See Figure 2-15.)

Figure 2-15: Line Module Connections

Note To connect a Catalyst 8540 device to a router (such as the Cisco 7500 router) with a UTP cable, use a straight-through cable. To connect the device to a switch (such as the Catalyst 5500 switch), use a crossover cable.

The LEDs on the faceplate of the line modules provide status information for the individual interface connections of the line modules.

The Catalyst 8540 CSR fiber line module LEDs are shown in Figure 2-16 and described in Table 2-2.
