C H A P T E R 1 Product Overview This chapter provides physical and functional overviews of the Cisco 7206 router. It contains physical descriptions of the router hardware and major components, and functional descriptions of hardware-related features. Descriptions and examples of software commands are included only when they are necessary for replacing, installing, configuring, or maintaining the router hardware.
Chapter 1 Product Overview Physical Description The Cisco 7206 provides the following features: • Online insertion and removal (OIR)—Allows you to add, replace, or remove port adapters without interrupting the system or entering any console commands. • Dual hot-swappable, load-sharing power supplies—Provide system power redundancy; if one power supply or power source fails, the other power supply maintains system power without interruption.
Chapter 1 Product Overview Physical Description The port adapters installed in the Cisco 7206 are of the same type as those installed on the second-generation Versatile Interface Processors (VIP2s) in the Cisco 7500 series routers, in Cisco 7000 series routers using the 7000 Series Route Switch Processor (RSP7000) and 7000 series Chassis Interface (RSP7000CI), and in the Cisco uBR7200 series routers. The port adapters installed in the Cisco 7206 support OIR.

You must power down the Cisco 7206 before removing the network processing engine from the router.
Chapter 1 Product Overview System Specifications The I/O controller, port adapters, power supplies, and network processing engine slide into their respective chassis slots and connect directly to the router midplane; there are no internal cables to connect. The midplane distributes DC power from the power supplies to the I/O controller, port adapters, fan tray, and network processing engine.

This LED remains off during normal operation of the router, unless there is an incoming carrier signal. SLOT 0 SLOT 1 Green Goes on to indicate which PC Card slot is in use by coming on when either slot is being accessed by the system.
Chapter 1 Product Overview Field-Replaceable Units The RJ-45 port is the default media type for the I/O controller that is equipped with an MII port and an RJ-45 port. Use the media-type command to change the I/O controller’s media type and the show interfaces command to verify the change. The following example configures the MII port as the media type for the I/O controller: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z.
Chapter 1 Product Overview Field-Replaceable Units Port Adapters and Service Adapters The Cisco 7206 is shipped from the factory with up to six installed port adapters and service adapters. Port adapters provide a variety of network media types (based on your order) for the router and service adapters provide hardware-based services (such as data compression and encryption) for the port adapter media types. The port adapters and service adapters connect directly to the router’s midplane.
Chapter 1 Product Overview Field-Replaceable Units H6432 Figure 1-15 Cisco 7206 AC-Input Power Supply Captive installation screw OK LED Power Power switch switch guard AC-input receptacle Handle The DC-input power supply has DC-input power leads that are hardwired to a DC-input terminal block. A cable tie is shipped with each DC-input power supply to secure the leads to the power supply faceplate and provide strain relief for the leads.
Chapter 1 Product Overview Field-Replaceable Units Note Each DC-input power supply operating at –48 VDC in North America requires a minimum of 13A service. Each DC-input power supply operating at –60 VDC in the European Union requires a minimum of 8A service. This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 20A minimum 60 VDC, is used on all current-carrying conductors.
Chapter 1 Product Overview Field-Replaceable Units Flash Disks and Flash Memory Cards The Cisco 7206 supports up to two installed Flash Disks or two Flash memory cards. Note To avoid potential problems when inserting spare Flash Disks or Flash memory cards in your Cisco 7206, we recommend that you reformat all of your Flash Disks or Flash memory cards on a Cisco 7206 that is running one of the recommended Cisco IOS software releases listed in Software Advisor.
Chapter 1 Product Overview Functional Overview Table 1-9 lists the factory-installed Flash Disk options and their product numbers Table 1-9 Flash Disk Memory Options Memory Size Product Number 40 MB MEM-I/O-FLD40M1 110 MB MEM-I/O-FLD110M1 1. 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=.
Chapter 1 Product Overview Functional Overview Port adapter slots maintain the same slot number regardless of whether other port adapters or service adapters are installed or removed. However, when you move a port adapter to a different slot, the port adapter slot number changes to reflect the new slot number.
Chapter 1 Product Overview Functional Overview MAC Address All LAN interfaces (ports) require unique MAC addresses, also known as hardware addresses. Typically, the MAC address of an interface is stored on a memory component that resides directly on the interface circuitry; however, the OIR feature requires a different method. For a description of OIR, refer to the “Online Insertion and Removal” section later in this chapter.
Chapter 1 Product Overview Functional Overview When you remove or insert a port adapter or service adapter in a Cisco 7206 router, the midplane pins send signals to notify the system, which then performs as follows: 1. Rapidly scans the midplane for configuration changes. 2. Initializes all newly inserted port adapters and service adapters, noting any removed port adapter interfaces and placing them in the administratively shutdown state. 3.

Chapter 1 Product Overview Functional Overview The low warning and high warning ranges in Table 1-11 are informational and if a low warning or high warning message appears, the warning message does not signify that an error or hazard is occurring. A high warning message sometimes appears in a lightly loaded chassis, especially if the router is running without port adapters or with dual power supplies.
Chapter 1 Product Overview Functional Overview The show environment last command retrieves and displays the NVRAM log, which shows the reason for the last system shutdown (if the shutdown was related to voltage or temperature) and the environmental status at that time. Air temperature is measured and displayed, and the DC voltage supplied by the power supply is also displayed.
Chapter 1 Product Overview Functional Overview Note Temperature ranges and values are subject to change. The show environment all command displays an extended report that includes temperature readings and voltage readings. The show environment all command also displays a report showing which power supply slots are occupied and which are empty. Following is sample output of the show environment all command: Router# show environment all Power Supplies: Power supply 1 is Zytek AC Power Supply. Unit is on.
