Step-by-Step Procedure
----------------------
Attach a terminal or PC with terminal emulation to the console port of the
router. Use the following terminal settings:
9600 baud rate
No parity
8 data bits
1 stop bit
No flow control
The required console cable specifications are described in the Cabling Guide
for RJ-45 Console and AUX Ports (Cisco's 1000 series, 2500 series, and
AS5100).
Type show version and record the setting of the configuration register.
Click here to see output of a show version command.
The configuration register setting is usually 0x2102 or 0x102.
Using the switch, turn off the router and then turn it on.
Press Break on the terminal keyboard within 60 seconds of the powerup to put
the router into ROMMON.
If the break sequence doesn't work, see Possible Key Combinations for Break
Sequence During Password Recovery for other key combinations.
Type confreg 0x2142 at the rommon 1> prompt to boot from Flash without
loading the configuration.
Type reset at the rommon 2> prompt.
The router reboots but ignores its saved configuration.
Type no after each setup question or press Ctrl-C to skip the initial setup
procedure.
Type enable at the Router> prompt.
You'll be in enable mode and see the Router# prompt.
Important Type config mem or copy start running to copy the nonvolatile RAM
(NVRAM) into memory. Do not type config term.
Type wr term or show running.
The show running and wr term commands show the configuration of the router.
In this configuration you see under all the interfaces the shutdown command,
which means all interfaces are currently shutdown. Also, you can see the
passwords either in encrypted or unencrypted format.
Type config term and make the changes.
The prompt is now hostname(config)#.
Type enable secret <password>.
Issue the no shutdown command on every interface that is used. If you issue
a show ip interface brief command, every interface that you want to use
should be "up up".
Type config-register 0x2102, or the value you recorded in step 2.
Press Ctrl-z to leave the configuration mode.
The prompt is now hostname#.
Type write mem or copy running startup to commit the changes.
