What Is the 4R Port Adapter? Token Ring Speed Considerations Before you install the 4R port adapter, determine the ring speed (4 or 16 Mbps) of each ring to be connected 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 with the ring-speed command) before you bring the interface up and insert it into the ring with the no shutdown command.

VIP2 and the 4R Port Adapter Caution To prevent interface reconfiguration requirements, you should replace a port adapter with the same type of port adapter you removed, but this is not a requirement. When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and so that air flows through the chassis properly.
VIP2 and the 4R Port Adapter Pulling a Port Adapter Out of a Slot (Partial Port Adapter View) H3149 Figure 10 If you removed a port adapter, place it in an antistatic container for safe storage or shipment back to the factory. If you removed a blank port adapter, no special handling is required; however, store the blank port adapter for potential future use. Step 8 Remove the new port adapter from its antistatic container and position it at the opening of the slot. (See Figure 11.
VIP2 and the 4R Port Adapter Caution Step 10 Carefully slide the new port adapter into the port adapter slot (Figure 12) until the connector on the port adapter is completely seated in the connector on the motherboard.
VIP2 and the 4R Port Adapter Attaching 4R Port Adapter Interface Cables The Token Ring ports on the 4R port adapter run at either 4- or 16 Mbps. You need one Token Ring interface cable for each 4R port adapter interface you want to use. Token Ring interface cables are not available from Cisco Systems, but are commercially available through outside cable vendors. Port adapters have a handle attached (see ), but this handle is not shown in to allow a full view of detail on the 4R port adapter’s faceplate.
VIP2 and the 4R Port Adapter Configuring the 4R Interfaces The following procedures describe basic configuration information for the 4R port adapter. If you installed a new 4R port adapter or if you want to change the configuration of an existing interface, you must enter configuration mode using the configure command. If you replaced a 4R port adapter that was previously configured, the system will recognize the new 4R interfaces and bring them up in their existing configuration.
VIP2 and the 4R Port Adapter For example, the addresses for the 4R interface ports on the first port adapter on a VIP2 (see ) are 3/0/0 through 3/0/3 (chassis slot 3, port adapter slot 0, and interface ports 0 through 3). If the 4R port adapter were installed in port adapter slot 1, the interface addresses would be 3/1/0 through 3/1/3. Note If you remove the 4R-equipped VIP2 (shown in ) from chassis slot 3 and install it in slot 2, the addresses of those same ports become 2/0/0 through 2/0/3.
