Product Description Product Description This section provides a description of Ethernet theory and of the EIP features and functions. Ethernet Overview The term Ethernet is commonly used for all carrier sense multiple access/collision detection (CSMA/CD) local area networks (LANs) that generally conform to Ethernet specifications, including IEEE 802.3. Ethernet Version 2 and IEEE 802.3 were based on, and developed shortly after, Ethernet Version 1. The slight differences between Ethernet and IEEE 802.
Product Description Ethernet is most similar to IEEE 802.3 10Base5. Both of these protocols specify a bus topology network with a connecting cable between the end stations and the actual network medium. Both protocols require a device that acts as an interface between the end stations in this case, the EIP) and the actual network medium (cable). The Ethernet specifications call this device a transceiver and it is connected to the station with a transceiver cable. The IEEE 802.
Product Description Table 2 lists the signals for the 15-pin Ethernet connector used on the EIP ports.
Product Description EIP Microcode The EIP microcode (firmware) is a software image that provides card-specific software instructions. A ROM component in socket U101 of the EIP module card contains the default EIP microcode. The router supports downloadable microcode, which enables you to upgrade microcode versions by downloading new microcode images, storing them in Flash memory, and instructing the system to load an image from Flash instead of the default ROM image.
Product Description Figure 3 shows an example of a typical Ethernet AUI connection. Figure 3 Ethernet Cable Connection To network EIP AUI or transceiver cable H1353a MAU or Ethernet XCVR Ethernet Connector Locks Ethernet ports use either slide-type locks (as shown in Figure 4) or screw-type locks (shown in Figure 5) to secure the cable to the port and provide strain relief. The slide-type lock is most common and is used on the EIP ports.
Product Description The slide-type locks are standard on the EIP ports; however, conversion kits are included with each EIP to replace the slide-type locks on ports you will connect to interface equipment that uses the screw-type locks. Cables with knurled thumbscrews (screws you can tighten with your fingers) on the cable connector need a port with jackscrews into which you insert and tighten the thumbscrews. (See Figure 5.

Installation Prerequisites Installation Prerequisites This section provides a list of parts and tools you will need to perform the installation, and safety and ESD-prevention guidelines to help you to avoid injury and damage to the equipment. It also provides a detailed description of the online insertion and removal (OIR) function to help you perform online installation successfully and avoid error message and system restarts.
Installation Prerequisites Ethernet Transceivers You need an Ethernet transceiver or media attachment unit (MAU) to connect the EIP port to the Ethernet network. Several types of single-port and multiport transceivers are available. The type you use depends on the type of cabling your Ethernet network uses: thick wire (10Base5), thin wire (10Base2), or unshielded twisted pair (10BaseT at 10 Mbps). Some examples are shown in Figure 11. You can connect either Ethernet Version 1 or Version 2/IEEE 802.
Installation Prerequisites Safety Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring. Electrical Equipment Follow these basic guidelines when working with any electrical equipment: • Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working. • • • • Disconnect all power and external cables before moving a chassis.
Installation Prerequisites • Handle carriers by the handles and carrier edges only; avoid touching the board or connectors; place a removed EIP board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag. • Avoid contact between the EIP and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Installation Prerequisites The system brings online only interfaces that match the current configuration and were previously configured as up; all other interfaces require that you configure them with the configure command. On interface processors with multiple interfaces, only the interfaces that have already been configured are brought online. The new interface remains in the administratively shutdown state until you configure it and bring it online.

Installation List of Parts and Tools You need the following tools and parts to install or upgrade an EIP. If you need additional equipment, contact a customer service representative for ordering information.
Installation Removing an EIP The EIP supports OIR; therefore, you need not shut down the interface or the system power when removing an EIP. If you are replacing a failed EIP, remove the existing board first, then replace the new EIP in the same slot. Figure 13 shows proper handling of an interface processor during installation. Figure 13 shows proper handling of an interface processor for installation in the Cisco 7010 and Cisco 7505 models.
Installation Step 6 If the interface processor slot is to remain empty, install an interface processor filler (MAS7K-BLANK) to keep dust out of the chassis and to maintain proper air flow through the interface processor compartment. To help prevent dust and contaminants from entering the chassis, do not leave the interface processor slot open. Immediately proceed to “Installing an EIP.” Installing an EIP The EIP slides into the open interface processor slot and directly to the backplane.
Installation Step 7 If you are using cables with slide-type locks, proceed to the next step. If you are using cables with screw-type locks, follow the instructions in the section “Replacing Connector Locks” on page 34, before proceeding. When the slide locks are replaced, proceed to the following step.
Installation When a new EIP is inserted or when an EIP is moved to a new slot, the system recognizes the new Ethernet interfaces but leaves them in a down state until you configure them and change their state to up with the configure command.
Configuring the Interfaces Step 7 When the interfaces are up, check the activity of each interface by observing the Ethernet interface status LEDs, which are described in the section “EIP LEDs” on page 4. If an error message is displayed on the console terminal, refer to the System Error Messages publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance. This completes the EIP installation.
Configuring the Interfaces Using the EXEC Command Interpreter Before you use the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The system will prompt you for a password if one has been set. The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, enter the privileged level as follows: Step 1 At the user-level EXEC prompt, enter the enable command.
Configuring the Interfaces Interface ports maintain the same address regardless of whether other interface processors are installed or removed. However, when you move an interface processor to a different slot, the first number in the address changes to reflect the new slot number. For example, on a six-port EIP in slot 1, the address of the first port (on the left) is 1/0 and that of the right-most port is 1/5.
Configuring the Interfaces Following is an example of how the show interfaces command, used without variables, displays status information (including the physical slot and port address) for each interface in the router. In the following example, most of the status information for each interface is omitted. Router# show int Serial0/0 is up, line protocol is up Hardware is cxBus Serial Internet address is 131.108.123.4, subnet mask is 255.255.255.
Configuring the Interfaces The following steps describe a basic configuration. Press the Return key after each configuration step unless otherwise noted. Step 1 At the privileged-level prompt, enter the configuration mode and specify that the console terminal will be the source of the configuration subcommands as follows: Router# configure terminal Enter configuration commands, one per line. Router(config)# End with CNTL/Z.
Configuring the Interfaces Checking the Configuration After configuring the new interface, use the show commands to display the status of the new interface or all interfaces. Command Descriptions and Examples Following are descriptions and examples of the show commands. Descriptions are limited to fields that are relevant for verifying the configuration.
Configuring the Interfaces • The show controllers cxbus command displays the internal status of each interface processor, including the interface processor slot location, the card hardware version, and the currently-running microcode version. It also lists each interface (port) on each interface processor including the logical interface number, interface type, physical (slot/port) address, and hardware (station address) of each interface.
Upgrading Microcode Using Show Commands to Verify the EIP Status The following summary describes how to use the show commands to verify that the new interfaces are configured correctly: Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new Ethernet interfaces. Step 2 Display all the current interface processors and their interfaces with the show controllers cxbus command. Verify that the new EIP appears in the correct slot.
Upgrading Microcode Caution Before you copy a file to Flash, be sure there is ample space available in Flash memory. Compare the size of the file you wish to copy to the amount of available Flash memory shown. If the space available is less than the space required by the file you wish to copy, the copy process will continue, but the entire file will not be copied into Flash. Follow these steps to copy a microcode version from the TFTP server to Flash memory.
Upgrading Microcode Step 7 If you do not want Flash erased, enter no at the next prompt. If you accept the default to erase by pressing Return without first typing no, the new image will write over the entire contents of Flash memory and you will lose all other microcode and system software images stored in Flash. Erase flash before writing? [confirm] no While the file is copied to Flash, output similar to the following is displayed: Loading from 131.108.12.
Replacing Connector Locks Step 14 To verify that the EIP is using the correct microcode, issue the show configuration or show controller cxbus command. The show controller cxbus display indicates the currently loaded and running microcode version for each interface processor. Router# show configuration This completes the procedure for downloading microcode to Flash memory.
Replacing Connector Locks Step 3 At the router privileged-mode prompt, enter the following command: Router# configure terminal Enter configuration commands, one per line. Router(config)# End with CNTL/Z. Step 4 Specify an Ethernet interface and enter the shutdown command to shut down the interface: Router(config)# interface ethernet slot/port Router(config-int)# shutdown Repeat step 4 for each Ethernet interface.
Replacing Connector Locks Step 4 Repeat steps 2 and 3 for the second jackscrew and lock washer, placing the second jackscrew in the other threaded hole on the connector. Step 5 Observe both jackscrews edge-on and turn them another half turn to ensure they are threaded properly. Step 6 Use the 3/16-inch nut driver to tighten the jackscrews in the connector.
