3.1.3 Linux serial console shell window
If the boot is not interrupted and has completed, the RS232 port accepts
administrator login for Linux shell access, and access to command line configuration
tools.
After successful login, the user may run any of the command line configuration tools
presented in section 3.4.5.

Description
admin admin The admin account was created for blade management activities.
This account should be used for all management and configuration
activities. Management logins may be performed via (1) Serial
console RS232, (2) ssh or (3) secure html on any Ethernet port.
root root The root account has master privileges with absolute power to
modify the blades Linux OS in any way desired.
It is unadvisable to use root as the normal user account because
simple typographical errors, accidental file deletions, or generating
unintentionally restrictive file permissions could render the blade
in-operable, requiring the factory reset procedure. For normal
activities, Emerson encourages using the admin user account and
judicious use of the su command only when root privileges are
really needed.
3.2.1 Password change procedure
The login password may be changed using the linux passwd command. For
example, if logged in as root, the password change procedure is shown:
#passwd
Changing password for root
Enter the new password (minimum of 5, maximum of 8 characters)
Please use a combination of upper and lower case letters and numbers.
Enter new password: xxxxxxx
Re-enter new password: xxxxxxx
Password changed.
