How to remove secondary-config? (7705 SAR-A)

[config_tea]

Hello,

I'm trying to load this password-protected unit with the default user/password of admin/admin.

I can specify the primary-config url as "none" after I interrupt the boot process, but there seems to be no option to remove the secondary-config, meaning the unit will still boot up with an old unknown password.

Is there an equivalent of a boot loader or rommon/shell that I can boot into instead?

Also: these units are riveted shut! I cannot access the compact flash.

Thanks for any suggestions!

SOLUTION:

Use TFTP server - IP address (for example) 192.168.0.10

Create blank text file called "config.cfg" in the TFTP root folder

Connect MGMT port to TFTP server (MGMT port IP will be assigned shortly)

INTERRUPT THE BOOT PROCESS:

Hit a key within 3 seconds to change boot parameters…
Type "sros" and hit ENTER within 29 seconds to begin changing parameters: sros


You must supply some required Boot Options. At any prompt, you can type:
"restart" - restart the query mode.
"reboot" - reboot.
"exit" - boot with existing values.

Press ENTER to begin, or 'flash' to enter firmware update… <ENTER>

Software Location
-----------------
You must enter the URL of the TiMOS software.
The location can be on a Compact Flash device,
or on the network.

Here are some examples
cf3:/timos1.0R1
ftp://user:passwd@192.168.1.150/./timos1.0R1
ftp://user:passwd@[3FFE::1]/./timos1.0R1
tftp://192.168.1.150/./timos1.0R1
tftp://[3FFE::1]/./timos1.0R1

The existing Image URL is 'cf3:\TiMOS-B-8.0.R10'
