Input/Output Controller Replacement Instructions 17
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.
• Handle the network processing engine, I/O controller, port adapters, or Cisco uBR7200 series
cable modem cards by their metal carrier edges and handles only; avoid touching the printed
circuit board components or any connector pins.
• When removing the network processing engine, I/O controller, port adapters, or Cisco uBR7200
series cable modem cards, place them on an antistatic surface with the printed circuit board
components facing upward, or in a static shielding bag. If you are returning an I/O controller,
network processing engine, port adapter, or Cisco uBR7200 series cable modem card to the
factory, immediately place it in a static shielding bag.
Caution Periodically check the resistance value of the antistatic strap. The measurement should be
within the range of 1 and 10 megohms.
Removing and Replacing the Input/Output Controller
The following sections explain how to remove and replace an I/O controller in the Cisco 7200 series
routers or Cisco uBR7200 series routers:
1 Copying the Configuration File to a TFTP Server, page 17
2 Powering Down the Router and Disconnecting Input Power, page 19
3 Removing the Input/Output Controller, page 24
4 Replacing an Input/Output Controller, page 25
5 Reconnecting Input Power and Powering Up the Router, page 27
6 Downloading the Saved Configuration from the TFTP Server and Configuring the I/O
Controller’s Fast Ethernet Port, page 33
Note The procedures for removing and replacing an I/O controller in all Cisco 7200 series routers
are the same. Therefore, the illustrations and procedures in the following sections apply to the
Cisco 7200 VXR routers and the Cisco 7200 routers (including the Cisco 7206 as arouter shelf in
the Cisco AS5800 Universal Access Server) unless indicated otherwise.
The procedures for removing and replacing an I/O controller in the Cisco uBR7200 series routers
are the same as for the platforms mentioned above; however, to show differences in the chassis and
I/O controller location, separate illustrations are provided for the Cisco uBR7200 series routers.
Copying the Configuration File to a TFTP Server
Before you replace the I/O controller, be sure to copy the router’s running configuration to a Trivial
File Transfer Protocol (TFTP) file server so that you can retrieve it later; otherwise, you will have to
reenter your configuration manually.
Before copying the router’s configuration file to a TFTP file server, check the following items:
• A console terminal is connected to the console port on the I/O controller, or a Telnet session is
established to the router.
