Emerson ATCA-S201 Linux serial console shell window, Default blade login accounts and passwords

RTM-ATCA-SXXX Overview

3.1.3Linux 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.

3.2Default blade login accounts and passwords

The ATCA-S201 includes two built-in user accounts for maintenance and management activities. Emerson recommends that administrators change the default passwords listed below for security purposes.

Table 6 Built-in user accounts included on a new ATCA-S201

User account	Default	Description
	password
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.

3.2.1Password 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.
