Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Safety Warnings Warning This warning symbol means danger. You are in a situation that could cause bodily injury.
Installation Prerequisites Advarsel Dette varselsymbolet betyr fare. Du befinner deg i en situasjon som kan føre til personskade. Før du utfører arbeid på utstyr, må du vare oppmerksom på de faremomentene som elektriske kretser innebærer, samt gjøre deg kjent med vanlig praksis når det gjelder å unngå ulykker.
Safety Guidelines Electrostatic Discharge Prevention Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards are improperly handled and results in complete or intermittent failures. The network processing engine, I/O controller, port adapters, and Cisco uBR7200 series cable modem cards consist of a printed circuit board that is fixed in a metal carrier.
Installation Prerequisites Caution Make sure to tighten the captive installation screws on the network processing engine, Cisco uBR7200 series cable modem cards, and the I/O controller (use a number 2 Phillips or a 3/16-inch, flat-blade screwdriver). These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the network processing engine, Cisco uBR7200 series cable modem cards, and the I/O controller are properly seated in the router midplane.
Removing and Replacing the Input/Output Controller Following are guidelines for preventing ESD damage: • Always use an ESD wrist strap or ankle strap when installing or replacing the network processing engine, I/O controller, port adapters, or Cisco uBR7200 series cable modem cards. Ensure that the ESD strap makes contact with your skin.
Removing and Replacing the Input/Output Controller • • • The router is connected to a network supporting a file server (remote host). The remote host supports the TFTP application. You have the name or address of the remote host. Complete the following steps to copy the router’s configuration file to a remote host: Step 1 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt for a pound sign [#]).
Powering Down the Router and Disconnecting Input Power While the router copies the configuration to the remote host, it displays a series of exclamation points (! ! !) or periods (. . .). The !!!! and [ok] indicate that the operation is successful. A display of . . . [timed out] or [failed] indicates a failure, which would probably be because of a network fault or the lack of a writable, readable file on the remote file server.
Removing and Replacing the Input/Output Controller Disconnecting AC-Input Power To disconnect AC-input power to a Cisco 7200 series router or Cisco uBR7200 series router, complete the following steps: Step 1 Unplug the input power cable from the power source.

(See Figure 22.) Stripping the DC-Input Leads H8624 0.55 in.
Reconnecting Input Power and Powering Up the Router Note Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat Step 3 through Step 5.
Removing and Replacing the Input/Output Controller Note For the Cisco 7200 series, 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 Community requires a minimum of 8A service. For the Cisco uBR7200 series routers, each DC-input power supply rating is 14A, 700 volt ampere (VA). This product relies on the building’s installation for short-circuit (overcurrent) protection.
Downloading the Saved Configuration from the TFTP Server and Configuring the I/O Controller’s Fast Ethernet Port Step 2 At the rear of the router, place the power switch on the power supply in the ON (|) position. Repeat this step if a second power supply is installed in the router. The green OK LED on the power supply turns on. Step 3 Listen for the fans; you should immediately hear them operating. Step 4 During the boot process, observe the system’s LEDs.
Removing and Replacing the Input/Output Controller Before configuring the new interface on the I/O controller, be prepared with the following information: • • Protocols and encapsulations you plan to use on the new interface Protocol specific information, such as Internet Protocol (IP) addresses if you will configure the interface for IP routing For complete descriptions of interface commands and the configuration options available for Cisco 7200 series and Cisco uBR7200 series-related interfaces, refer
Downloading the Saved Configuration from the TFTP Server and Configuring the I/O Controller’s Fast Ethernet Port While the router retrieves and boots from the configuration on the remote host, the console display indicates whether or not the operation was successful.
