These products are also available as Flash Disk upgrades. To order an upgrade, add an equal sign (=) after the product number, for example, MEM-I/O-FLD110M=. Rack-Mount and Cable-Management Kit The rack-mount and cable-management kit for the Cisco 7206 consists of rack-mount and cable-management brackets that are designed for mounting your router in 19-inch, four-post or telco-type equipment racks and for relieving strain on port adapter interface cables that are installed on port adapters in the router. The kit is shipped with each Cisco 7206 and is also available as a single FRU. For detailed instructions about how to install the rack-mount and cable-management brackets on your Cisco 7206, refer to Chapter 3, "Installing the Cisco 7206," the "Rack-Mounting the Cisco 7206" section on page 3-2 and the "General Tabletop or Workbench Installation" section on page 3-9. Functional Overview This section provides a functional overview of the Cisco 7206. It describes the numbering and addressing scheme of the port adapters for the router, the environmental monitoring and reporting functions, and online insertion and removal (OIR). These descriptions will help you become familiar with the capabilities of the Cisco 7206 router. Port Adapter Slot and Logical Interface Numbering In the Cisco 7206, the port adapter slot number is the chassis slot in which a port adapter or service adapter is installed, whereas the logical interface number is the physical location of the interface port on a port adapter (service adapters do not have interface ports). Port adapter slots are numbered from 1 through 6; port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller-if present. (Refer to Figure 1-2 for the numbering scheme of the port adapter slots.) The number of logical interfaces depends on the type of port adapter. Note For information about port adapter slot numbering and logical interface numbering for a Cisco 7206 as router shelf in a Cisco AS5800 Universal Access Server, refer to the Cisco AS5800 Universal Access Server documentation listed in the Preface, "Related Documentation" section on page xiv. The Media Access Control (MAC) or hardware address is a standardized data link layer address that is required for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The Cisco 7206 uses a specific method to assign and control the MAC addresses of its port adapters. For a description of the MAC address, refer to the ""MAC Address" section on page 1-30" section later in this chapter. 1-28 Cisco 7206 Installation and Configuration Guide OL-5102-02
