In-Depth Information
Figure 25-2 shows a flowchart that describes the password-recovery procedure for the following
platforms:
•
CGS, MGS, AGS, and AGS+ routers running Software Release 9.1(6) and earlier
•
Cisco 7000 series routers running Software Release 9.17(3) and earlier from ROM
The step-by-step procedure that follows and the password recovery flowchart shown in Figure 25-2 apply
only to the indicated platforms running the indicated software. There is another procedure for recovering
a password on these platforms if they are running more recent software. See the previous section,
“Password-Recovery Procedure: Platforms Running Recent Software Releases.”

To complete this procedure, you must have a terminal or a personal computer (running
terminal emulation software) connected to the console port of the router.
Note
The following is the password-recovery procedure for Cisco platforms running earlier software releases:
Power down the router.
Step 1
Change the hardware configuration register by moving the jumper from bit position 0 or 1 to bit position
15.
Note the original position of the jumper.
