    While the VIP2 supports online insertion and removal (OIR), individual port adapters do not. To replace Note port adapters in Cisco 7000 series and Cisco 7500 series routers, you must first remove the VIP2 from the chassis and then replace port adapters as required. Cisco 7200 series routers support OIR of port adapters.

    Manchester All PA-4R-DTR interfaces support both 4- and 16-Mbps, half-duplex and full-duplex operation, concentrator port and station port operation, and early token release. You can change the configuration using the following commands issued in configuration mode: To enable 16-Mbps operation, specify the slot/port address and use the ring-speed 16 command.

  • Page 11: Token Ring Port Operation

    Full-duplex station emulation—The port is connected to a switch or a concentrator port in • full-duplex mode. In a typical half-duplex Token Ring network, lobe cables connect each Token Ring station (PA-4R-DTR interface) to the MAU and patch cables connect adjacent MAUs to form one large ring. (See Figure 1-2.)
  • Page 12 Lobe cables Stations Stations In a typical full-duplex Token Ring network, lobe cables connect each Token Ring station (PA-4R-DTR interface) to the Token Ring switch and patch cables connect adjacent Token Ring switches to form one large ring. (See Figure 1-3.)

  • Page 13: Dedicated Token Ring

    You need an IEEE 802.5 MAU, MSAU, or a Token Ring switch to provide the interface between the PA-4R-DTR Token Ring interfaces and the external ring. You also need a Token Ring lobe cable between each PA-4R-DTR interface and the MAU, MSAU, or the Token Ring switch.

  • Page 14: Token Ring Distance Limitations

    Token Ring Speed Considerations Before you install the PA-4R-DTR, determine the ring speed of each ring that you plan to connect to the server. There is no factory default for the interface speed. You must set the speed of each interface (within the setup command facility or using the ring-speed command) before you bring up the interface and insert it into the ring using the no shutdown command.

    Port adapter handles not shown In the Cisco 7000, Cisco 7507, and Cisco 7513 chassis, the VIP motherboard is installed vertically. In Note the Cisco 7010 and Cisco 7505 chassis, the VIP motherboard is installed horizontally. Interface processor slots are numbered as shown in Figure 1-13.

  • Page 20: Cisco 7100 Series Routers Interface Addresses

    The interface addresses of the interfaces on the PA-4R-DTR in port adapter slot 1 are 1/0 through 1/3 (port adapter slot 1 and interfaces 0 through 3). If the PA-4R-DTR was in port adapter slot 4, these same interfaces would be numbered 4/0 through 4/3 (port adapter slot 4 and interfaces 0 through 7).

  • Page 21: Vip2 Interface Addresses

    If the VIP2 is inserted in interface processor slot 3, then the interface addresses of the PA-4R-DTR are 3/1/0 through 3/1/7 (interface processor slot 3, port adapter slot 1, and interfaces 0 through 7). If the port adapter was in port adapter slot 0 on the VIP2, these same interface addresses would be numbered 3/0/0 through 3/0/7.

    Checking Hardware and Software Compatibility Checking Hardware and Software Compatibility To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether modules within a system are compatible, but it does provide the minimum IOS requirements for individual hardware modules or components.

    You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: Turn the television or radio antenna until the interference stops.

    Each PA-4R-DTR interface must be configured for the same ring speed as the ring to which it is connected (4 or 16 Mbps). If the PA-4R-DTR interface is set for a different speed, it causes the ring to beacon, which brings down the ring.

    This completes the procedure for creating a basic configuration. Configuring Full-Duplex Operation Full-duplex operation is not the default configuration of a PA-4R-DTR interface and must be turned on using the full-duplex command. To turn off full-duplex operation and reset the interface, use the no full-duplex or half-duplex command.

  • Page 48: Using Loopback Commands

    With the loopback test, you can detect and isolate equipment malfunctions by testing the connection between the PA-4R-DTR interface and a remote device such as a modem or a CSU/DSU. The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device such as a MAU, MSAU, or Token Ring switch.
