Maintaining the Cisco 2500 Series Access Server B-15

Recovering a Lost Enable Password

Note To recover a lost enable password if Break is disabled on the router, you must have

physical access to the access server.

Take the following steps to recover a lost enable password:

Step 1 Attach an ASCII terminal to the access server console port, which is located on

the rear panel.

Step 2 Conﬁgure the terminal to operate at 9600 baud, 8 data bits, no parity, 2 stop bits.

Step 3 Enter the command show version to display the existing conﬁguration register

value.

Step 4 If Break is disabled, power cycle the access server. (Turn the access server off,

wait ﬁve seconds, and then turn it on again.) If Break is enabled on the access

server, send a Break and then proceed to Step 6.

Step 5 Within 60 seconds of turning on the access server, press the Break key. This action

causes the terminal to display the bootstrap program prompt (>).

Step 6 To reset the conﬁguration register to boot from the boot ROMs and ignore

NVRAM, enter o/r at the bootstrap prompt as follows:

> o/r 0x042

Step 7 Initialize the access server by entering the command initialize as follows:

> i

The access server will power cycle; the conﬁguration register will be set to 0x142;

and the access server will boot the boot ROM system image and prompt you with

the system conﬁguration dialog as follows:

--- System Configuration Dialog ---

Step 8 Enter no in response to the system conﬁguration dialog prompts until the

following system message is displayed:

Press RETURN to get started!
