Doc. No. 78-1065-03 Token Ring Interface Processor (TRIP) Installation and Configuration Product Numbers: CX-TRIP2 and CX-TRIP4 This document provides instructions for installing the Token Ring interface processor (TRIP) in your Cisco 7000 and Cisco 7500 series routers. The TRIP provides two or four IEEE 802.5 Token Ring network interfaces.
Product Description Product Description This section contains a detailed description of the Token Ring interface processor (TRIP). The TRIP, shown in Figure 1, provides two or four Token Ring ports for interconnection with IEEE 802.5 and IBM Token Ring media. The TRIP uses the IBM 16/4-Mbps chipset with an imbedded performance enhanced interface driver and 16.7 MHz bit slice processor for high speed processing. The speed on each port is set independently with a software command for either 4 or 16 Mbps.
Product Description When a Token Ring interface is configured by using software commands, three LEDs for each port indicate the following: • • • 16 Mbps—Lights if the interface is operating at 16 Mbps. 4 Mbps—Lights if the interface is operating at 4 Mbps. In Ring—When lit, indicates that the interface is currently active and inserted into the ring. When not lit, the interface is not active and is not inserted into a ring. Token Ring Connection Equipment You will need an 802.
Product Description Figure 3 Token Ring Type 3 Lobe Cable Connectors, DB-9 and RJ-11 Types MAU end H2055 TRIP end Token Ring Physical Connections The term Token Ring refers to both IBM’s Token Ring Network, which IBM developed in the 1970s, and to IEEE 802.5 networks. The IEEE 802.5 specification was modeled after, and still closely shadows, IBM’s network. The two types are compatible, although the specifications differ slightly. Token Ring and IEEE 802.
Product Description In the typical Token Ring network shown in Figure 4, lobe cables connect each Token Ring station (TRIP port) to the MSAU (or MAU), and patch cables connect adjacent MSAUs (or MAUs) to form one large ring.
Product Description What is the Cisco 7000 Series?

Product Description What is the Cisco 7500 Series? The Cisco 7500 series consists of three router models: the Cisco 7505, the Cisco 7507, and the Cisco 7513. All three models provide high reliability, availability, serviceability, and performance.
Product Description Figure 8 shows the rear of the seven-slot Cisco 7507 router. In the Cisco 7507, up to two slots (2 and 3) are reserved for the Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 and 1, and 4 through 6 are for interface processors.
Product Description Figure 9 shows the rear of the Cisco 7513, with two AC-input power supplies installed. Two slots (6 and 7) are reserved for the second generation Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 through 5, and 8 through 12 are for interface processors.
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 Telephone Wiring Safety Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling: • • Never install telephone wiring during a lightning storm. • Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. • Use caution when installing or modifying telephone lines.
Installation Prerequisites Online Insertion and Removal—An Overview Online insertion and removal (OIR) allows you to remove and replace interface processors while the system is operating; you do not need to notify the software or shut down the system power. This section describes the mechanical functions of the system components and stresses the importance of following the correct procedures to avoid unnecessary restarts or card failures. This section is for background information only.
Installation Prerequisites The function of the ejector levers (see Figure 10) is to align and seat the card connectors in the backplane. Failure to use the ejectors and insert the interface processor properly can disrupt the order in which the pins make contact with the backplane.

Installation List of Parts and Tools Verify that you have all of the parts and optional equipment you will need to install the TRIP. If you need additional equipment, contact a service representative for ordering information. • • One TRIP • • 9-pin male connector for each Token Ring connector on TRIP One Token Ring 802.
Installation Step 4 Store the interface processor filler for future use. To help prevent dust and contaminants from entering the chassis, do not leave the interface processor slot open. Immediately proceed to the section “Installing a TRIP” on page 18. Removing a TRIP The TRIP supports OIR; therefore, you need not shut down the interface or the system power when removing a TRIP. If you are replacing a failed TRIP, remove the existing board first, then replace the new TRIP in the same slot.
Installation Step 5 Place the removed TRIP on an antistatic mat or foam pad, or place it in an antistatic bag if you will return it to the factory. 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.
Checking the Installation Step 7 Attach network interface cables or other connection equipment to the interface ports. (See Figure 12). Figure 12 Token Ring Connections H1383a TRIP MAU Step 8 Check the status of the interfaces as follows: • If this installation was a replacement TRIP, use the show interfaces or show controller [type] command to verify that the system has acknowledged the new interfaces and brought them up.
Configuring the Interfaces 4 IN Mb Mbp RIN ps s G TRIP LEDs H2065 2 3 0 1 16 EN A BL ED Figure 13 Configuring the Interfaces You can modify the startup configuration for Cisco 7000 series and Cisco 7500 series routers through the software command interpreter called EXEC. To configure the interfaces for interface processors, you can use either one of the following EXEC commands: setup configure The setup command facility can be used after first time startup to make basic changes at any time.
Configuring the Interfaces To configure Token Ring interfaces using the setup EXEC command facility, follow the instructions in the section “Using the Setup Command” on page 21. To configure the Token Ring interfaces by using the configure EXEC command, follow the instructions in the section “Using the Configure EXEC Command” on page 22.
Configuring the Interfaces Step 3 Proceed through the remainder of the global parameter prompts, using the Return key to accept the defaults. After the global parameters are configured, the system prompts you for interface configuration information, one interface at a time.
Configuring the Interfaces Basic Configuration Guidelines Following are instructions for a basic configuration: enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending upon the requirements for your system configuration. (Configuration subcommands are described in the Router Products Configuration Guide, available on UniverCD or in print.
Checking the Configuration Checking the Configuration After configuring the new interface(s) using either the setup command or the configure command, use the EXEC show commands to display status information. Step 1 To display the current system configuration file, enter the show configuration command: Router# show configuration The configuration file for the router is displayed. Check the Token Ring configuration information in the display.
Upgrading Microcode Upgrading Microcode Depending on how it is configured, the Cisco 7000 series router allows the Switch Processor (SP) and interface processors to use updated microcode that is available either in Flash memory on the Route Processor (RP) or on the onboard ROM for each processor. The Cisco 75000 series routers allow the interface processors to use updated microcode that is available either in Flash memory on the Route Switch Processor (RSP) or on the onboard ROM for each processor.
Upgrading Microcode Step 5 Confirm that you want the file copied into Flash: Copy trip1-0 from 131.108.13.111 into flash memory? [confirm] yes Step 6 If you do not want the other microcode files in Flash memory erased, enter no OR If you want Flash erased, enter yes. Erase flash before writing? [confirm] no If you answered yes, the Flash memory is erased, and the TRIP microcode is copied to Flash memory. Output similar to the following is displayed: Zeroing bank...zzzzzzzzzzzzzzzz Verify zeroed...
Upgrading Microcode Step 13 Verify that the correct microcode version is available in Flash memory: Router# show controllers token You have now completed downloading microcode to the Flash memory, downloaded the microcode to the TRIP, added the microcode commands to the configuration file, and updated the NVRAM with the new configuration file.
