This chapter describes how to install the switch route processor in the five-slot chassis, and includes the following sections:
| Warning Read the installation instructions before you connect the system to its power source. |
| Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. |
This section includes information about the following preinstallation requirements:
| Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
| 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 Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. |
| Warning This device might have more than one power cord. To reduce the risk of electric shock, disconnect the two power-supply cords before servicing the device. |
| Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
| Warning Do not work on the device or connect or disconnect cables during periods of lightning activity. |
Follow these guidelines when working with any electrical equipment:
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.
| Caution Always tighten the captive installation screws on the switch route processor and line modules when you are installing them. These screws prevent accidental removal of the switch 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:
| Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms). |
Before installing the device, have all additional external equipment and cables on hand.
The unshielded twisted-pair (UTP) port on the Catalyst 8510 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," which lists the signals for the RJ-45 cable connector.
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.
| Transceiver Speed | Cable Type | Maximum Distance Between Stations |
|---|---|---|
10/100 Mbps | Category 5 UTP | 328 feet (100 meters) |
100 Mbps | Multimode fiber | 1640 feet (500 meters) |
1000 Mbps | Multimode fiber | 1640 feet (500 meters) |
For fiber-optic traffic, use the SC-type connector to connect the line modules with the external connection. This connector is shown in Figure 2-2.
| Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. |
For UTP traffic, use the RJ-45 connector (Figure 2-3) to connect the line modules with the external switch.
The Catalyst 8510 uses a five-slot modular chassis. Slot 2 is reserved for the switch route processor, as shown in Figure 2-4. The other four slots are used for line modules.
| Caution Make sure blank slot fillers cover all unused slots to ensure proper airflow within the chassis. |
To install the switch route processor, follow these steps:
Step 1 Turn off the device, but to channel ESD voltages to ground, do not disconnect the power cable.
| Caution The switch route processor is a required system component. Removing or installing a switch route processor while the device is operating causes the system to shut down and might damage the processor. Turn off the device before removing or installing the switch route processor. |
Step 2 Hold the switch route processor faceplate with one hand, and place your other hand under the processor. Avoid touching the components on top of the processor. (See Figure 2-5.)
| Caution Handle the switch route processor only by the edges to prevent ESD damage. |
Step 3 Align the switch route processor with the rails on the inside of the chassis.
Step 4 Carefully slide the switch route processor into slot 2 (or slot 13 of the Catalyst 5500 switch) until the switch route processor stops and the ejector levers are protruding outward.
Step 5 Put your thumbs on the left and right ejector levers and simultaneously push inward on the levers to seat the switch route processor in the backplane connector.
| Caution Always use the ejector levers when installing or removing the switch route processor. A processor 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 switch route processor.
Step 7 Attach network interface cables or other devices to the interface ports.
Step 8 Turn on the device.
This section describes how to connect the switch route processor to a network:
Before connecting the switch route processor to a network, consider the following:
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."
Use a straight-through Ethernet cable with RJ-45 male connectors (see Figure 2-6) 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.
The switch route processor includes one EIA/TIA-232, data terminal equipment (DTE) auxiliary port and one EIA/TIA-232, data communications equipment (DCE) console port (see Figure 2-7). These ports provide 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 DTE device to the auxiliary port or a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port.
The console and auxiliary ports differ in that the auxiliary port supports hardware flow control and modem control, and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, the sending device receives a message to suspend transmission until the data in the buffers is processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.
EIA/TIA-232 supports unbalanced circuits at signal speeds of up to 64 kbps. Figure 2-8 shows the connectors at the network end of the adapter cable for DCE and DTE connections.
The auxiliary port on the switch route processor is a male, EIA/TIA-232, DTE, DB-25 plug. Attach a device to access the Catalyst 8510 from the network. The asynchronous auxiliary port supports hardware flow control and modem control. The auxiliary port requires a null-modem EIA/TIA-232 cable. Table B-2 in the appendix "Cable and Port Pinouts" lists the signals used on this port.
The console port on the switch 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-3 in the appendix "Cable and Port Pinouts" lists the signals used on this port.
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:
The switch route processor includes two Personal Computer Memory Card International Association (PCMCIA) card slots---slot 0 and slot 1---that accept 8-MB, 16-MB, or 20-MB Series 2+ Flash memory cards purchased from Cisco. The Flash memory card is used to store the system image, and can also be used to store software and microcode images for other systems.
To install and remove a Flash memory card, follow these steps:
Step 1 Face the front panel of the switch route processor (see Figure 2-9) 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 2-9a).
Step 2 Insert the card into the appropriate 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 2-9b). Note that the card does not insert all the way inside the switch route processor; a portion of the card remains outside of the slot. Do not attempt to force the card past this point.
Step 3 To eject the card, press the EJECT button corresponding to the slot until the card is free of the connector at the back of the slot. (See Figure 2-9c.)
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 8510 Campus Switch Router Software Feature and Configuration Guide for configuration instructions.
| Caution Although line modules support hot swapping, the switch route processor does not. The switch route processor is a required system component, and removing it while the device is operating causes the system to shut down and can damage the processor. |
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.
Router# %OIR-6-REMCARD: Card removed from slot 3/0, interfaces disabled %LINK-5-CHANGED: Interface 3/0, changed state to administratively down %LINK-5-CHANGED: Interface 3/0, 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, changed state to up %LINK-5-CHANGED: Interface 3/0, changed state to up Router#
The ejector levers and captive installation screws (Figure 2-10) align and seat the module connectors in the backplane.
Follow the installation and removal instructions carefully, paying special attention to the following practices:
To ensure that the module connector pins disconnect from the backplane in the sequence expected by the system, use the ejector 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. Detailed steps for correctly performing hot swapping are included in the following procedures for installing and removing line modules.
Following are detailed steps for removing and replacing line modules and successfully performing hot swapping.
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."
This section explains the procedures for removing line modules.
Follow these steps to remove a line module:
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 ejector 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, keeping your other 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.
| Caution Always install line module filler plates in empty slots to maintain the proper flow of cooling air across the modules. |
You can install line modules in any of the four line module slots numbered 0 through 4 from top to bottom when viewing the chassis from the front. (See Figure 2-11.) The middle slot (number 2) contains the switch route processor, which is a required system component. Blank line module fillers are installed in empty slots to maintain consistent airflow through the module compartment.
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.
| Caution Handle the line module by the edges only to prevent ESD damage. |
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 (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 2-12.)
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 and carefully slide it into the slot until the faceplate makes contact with the ejector 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 ejector 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:
The following sections describe how the Catalyst 8510 assigns and controls both the physical (module/submodule/port) and Media Access Control (MAC)-layer addresses for interfaces within the chassis.
In the Catalyst 8510, port IDs specify the actual physical location of each line module port on the front of the chassis. (See Figure 2-13.) 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 4 from top to bottom. 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.
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 an eight-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 1/0/7. If you remove the line module from slot 1 and install it in slot 4, the addresses of those same ports become 4/0/0 and 4/0/7.
The following line modules are described in this section:
Software and upgrades require specific document part numbers and other frequently updated information. Detailed instructions are included in the Catalyst 8510 Campus Switch Router Software Feature and Configuration Guide.
This section shows the required connection equipment and line module network connections and LEDs.
The Catalyst 8510 line modules can support interfaces that connect to Layer 2 or Layer 3. (See Figure 2-14.)
The LEDs on the faceplate of the line modules provide status information for the individual interface connections of the line modules. The LEDs for a UTP Ethernet line module are shown in Figure 2-15.
The Catalyst 8510 Ethernet line module LEDs show the illumination conditions described in Table 2-2.
| LED | Description |
|---|---|
RX (Receive) | When a port is receiving a packet, the LED is green for approximately 50 ms; otherwise, it is off. |
TX (Transmit) | When a port is transmitting a packet, the LED is green for approximately 50 ms; otherwise, it is off. |
LINK | If the port is operational (a signal is detected), the LED is green. |
100 Mbps | When green, the port is operating at 100 Mbps. If the LED is off, the port is operating at 10 Mbps. |
The Gigabit Ethernet line module LEDs are depicted in Figure 2-16 and described in Table 2-3.
| LED | Description |
|---|---|
RX-SYNC | This LED reflects the synchronization of the link negotiation process. It is steadily on when there is a gigabit connection. |
TX (Transmit) | When a port is transmitting a packet, the LED is green for approximately 50 ms; otherwise, it is off. |
RX-LOSS | This LED indicates the detection of an optical signal from another Gigabit Ethernet device. It is steadily on when there is a gigabit connection. |
LINK-ON | If the port is operational (a signal is detected), the LED is green. |
RX (Receive) | When a port is receiving a packet, the LED is green for approximately 50 ms; otherwise, it is off. |
RX-FULL | This LED is on when the port is operating in full-duplex mode, which is always the case for an operational Gigabit Ethernet port. |
