Installing and Connecting Components

Keep the chassis area clear and free of dust during and after installation.
Keep tools and chassis components away from walk areas.
Fasten your tie or scarf and roll up your sleeves. Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the chassis.

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 interface 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.
Never install telephone wiring during an electrical storm.

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 interface 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 interface 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 interface modules when you are installing them. These screws prevent accidental removal of the route processor and interface 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 ESD wrist strap to the ESD strap connection at the bottom of the chassis 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 CSR chassis, consider these factors for each type of interface:

Cabling required for each type (multimode 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 interface module is an RJ-45 receptacle. If you intend to build your own cables, refer to Table B-1 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, multimode 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. Table 2-1 lists the recommended maximum cable lengths.

Transceiver Speed	Cable Type	Maximum Distance Between Stations
10/100 Mbps	Category 5 UTP	328 ft (100 m)
100 Mbps	Multimode fiber	1640 ft (500 m)
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 interface 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 interface modules with the external connection. Figure 2-3 shows the fiber-optic connector (MT-RJ).

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

For 1000-Mbps fiber-optic traffic, use the SC-type connector to connect the Gigabit Ethernet interface modules with the external connection. Figure 2-4 shows this connector.

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

Installing the Route Processor or Switch Modules

This section describes how to install a route processor or switch modules 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 "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 filler plates 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.

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.

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

To install the route processor or switch modules, follow these steps:

Step 1 Turn off the Catalyst 8540 CSR chassis, 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 a route processor or switch module while the Catalyst 8540 CSR is operating causes the system to shut down and might damage the processor. Turn off the Catalyst 8540 CSR chassis 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.

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 release 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.

Figure 2-6: Route Processor Installation

Step 6 Use a 3/16-inch 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 to the interface ports.

Step 8 Turn on the Catalyst 8540 CSR chassis.

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 "Cable and Port Pinouts."

Ethernet Port Connections

Use a straight-through Ethernet cable with RJ-45 male connectors (see Figure 2-7) between the Ethernet port and an Ethernet network. Table B-1 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 connection) 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 DTE and DCE 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 lists the signals used on this port.

Note The console port is an asynchronous serial port; any device 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 PC Cards

This section describes how to install and remove Flash PC Cards. 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. 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 Layer 3 Switching 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 PC Cards. The Flash PC Card stores the system image and can also store software and microcode images for other systems.

Note You can install or remove a Flash PC Card with the power on.

To install a Flash PC Card, follow these steps:

Step 1 Face the front panel of the route processor (see Figure 2-10) 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 2-10a).

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).

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

Note

To remove a Flash PC Card, follow these steps:

Step 1 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 2 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 PC Cards. Refer to
the Layer 3 Switching Software Feature and Configuration Guide for
configuration instructions.

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

Installing and Removing Interface Modules

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

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

Note Wait at least one minute after removing an interface module before inserting a
new one.

Sample Console Display for Hot-Swapping Procedure

When you remove and replace interface 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 an interface module is removed from slot 3. When the interface module is reinserted, the system marks the module as ready again.

Interface 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 interface 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 interface module in the backplane. This ensures that the module connector mates with the backplane correctly. If you use the faceplate, the interface module might seat improperly.
Use the release levers and captive installation screws to insert an interface module, and be sure to push the release levers to the full 90-degree angle. 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 interface 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 interface 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 an interface module. Any interface module that is only partially connected to the backplane will halt the system.

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

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

Removing Interface Modules

This section explains the procedures for removing interface modules.

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

Follow these steps to remove an interface 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 interface module that is to be removed.

Caution Failure to disconnect cables could damage the interface module.

Step 2 Loosen the captive installation screws at the left and right sides of the interface 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 interface module from the backplane connector.

Step 4 Grasp the interface 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 interface module straight out of the slot carefully, placing one hand under the module to guide it. Keep the module at a 90-degree angle to the backplane.

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

Step 7 If the interface 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.

Note Wait at least one minute after removing an interface module before inserting a
new one.

Installing Interface Modules

You can install interface modules in any of the eight interface 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 interface module filler plates in empty slots to maintain consistent airflow through the module compartment.

Figure 2-12:
Interface Module Slot Numbers

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

Note Wait at least one minute after removing an interface module before inserting a
new one.

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

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

Step 2 Use a 3/16-inch flat-blade screwdriver to loosen the captive installation screws and remove the interface module filler plate (or the existing interface module) from the slot you want to use.

Step 3 Hold the interface 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.)

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

Step 5 Keep the interface module at a 90-degree angle 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 interface module is fully seated in the backplane connector.

Caution
Always use the release levers when installing or removing the interface module. Leaving an interface module only partially seated in the backplane causes the system to halt and subsequently crash. Use a screwdriver to tighten the captive installation screws on the left and right ends of the interface module.

Figure 2-13: Interface Module Installation

Step 7 Attach network interface cables to the interface ports.

Step 8 Check the status of the interfaces as follows:

If this installation is a replacement interface 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 Layer 3 Switching Software Feature and Configuration Guide for all software configuration instructions and information.

Catalyst 8540 Interface Names

The Catalyst 8540 CSR interface names identifies specify the actual physical location of each interface module port. (See Figure 2-14.) The interface name 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 interface module number. Within the Catalyst 8540 CSR chassis, this number is always 0, as there can only be one interface module per slot. The third number identifies the physical port number on the interface 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: Interface Name Examples

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

For example, on a 16-port 10/100 interface 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 interface 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 chassis. 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.

Interface Module Configuration

Interface modules support different media and interface types. The configuration commands used with these different interface modules vary according to interface module type. For complete interface module configuration information, refer to the Layer 3 Switching Software Feature and Configuration Guide.

Cabling the Interface Modules

This section describes contains information on cabling the Catalyst 8540 CSR interface 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 network requirements change, you might want to upgrade your system, add components, or change the initial configuration.

The Catalyst 8540 CSR interace modules use either UTP or fiber transmission cabling. You must use the appropriate interface cable to connect an interface module to an external network. (See Table 2-2.)

Interface Module	Cable Type	Number of Ports
Eight-port Gigabit Ethernet	Multimode fiber	8 fiber ports
Two-port Gigabit Ethernet	Multimode fiber	2 fiber ports
10/100BaseT	Category 5 UTP	16 UTP ports

Interface Module Cable Types

All Catalyst 8540 CSR interfaces are bidirectional. This section shows the required connection equipment and interface module network connections and LEDs. (See Figure 2-15.)

Figure 2-15: Interface Module Connections

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

The LEDs on the faceplate of the interface modules provide status information for the individual interface connections of the interface modules. Refer to the "Interface Module LEDs" section for more LED information.

Installing the ACL Daughter Card

You can install the ACL (access control list) daughter card on the 10/100BaseT, 100BaseFX, or the two-port Gigabit Ethernet interface module. This section describes the process for installing the ACL daughter card on an interface module when it is shipped as a spare unit.

Note The eight-port Gigabit Ethernet interface module does not support the ACL daughter card.

Ensure that the interface module meets the minimum hardware version necessary before you install the ACL daughter cards. (See Table 2-3.) Use the show hardware command at the IOS prompt to display the version.

Interface Module	Hardware Version
Two-port Gigabit Ethernet	Version 2.0 and above

ACL Hardware Requirements

You need the following parts and tools:

A 1/4-inch socket driver
A screwdriver
A set of 12-mm mounting standoffs
An ACL daughter card

Follow these steps to install an ACL daughter card onto an interface module.

Step 1 If necessary, remove the interface module from the Catalyst 8540 CSR chassis. See the "Installing and Removing Interface Modules" section for instructions.

Step 2 Place the interface module on an antistatic mat or bag.

Step 3 Remove the six M3x.5 screws on the interface module and replace them with the 12-mm mounting standoffs. (See Figure 2-16.) Use the 1/4-inch socket driver to install the 12-mm mounting standoffs.

Figure 2-16: Removing the Screws from the Interface Module

Step 4 Remove the ACL daughter card from the antistatic bag and position it correctly over the mounting standoffs. (See Figure 2-17.) Ensure that the mounting holes are aligned with the standoffs.

Figure 2-17: Proper Position of the ACL Daughter Card on the Interface Module

Step 5 Press down firmly on the ACL daughter card to properly seat the ACL daughter card onto the interface module. First press down in the center of the daughter card. (See Figure 2-18a.) Then press down evenly on the sides of the daughter card. (See Figure 2-18b.) When the ACL daughter card is seated fully onto the standoffs, proceed to the next step.
