Removing and Replacing the Input/Output Controller
Removing the Input/Output Controller
To remove an I/O controller from a Cisco 7200 series router or Cisco uBR7200 series router,
complete the following steps:
Note Before removing the I/O controller, save the router’s configuration to a TFTP file server. (See
the “Copying the Configuration File to a TFTP Server” section on page 17.)
Step 1 Power down the router and disconnect the input power cable. (See the “Powering Down
the Router and Disconnecting Input Power” section on page 19.)
Step 2 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 3 Disconnect the cables from the I/O controller’s console, auxiliary, and Fast Ethernet (if
present) ports. (For a Cisco 7200 series router, see Figure 14. For a Cisco uBR7200 series
router, see Figure 15.)
