HP AlphaServer TS15 Owner's Manual page 159

When you enter the login command, you are prompted for the current system password. If a
password has not been set, a message is displayed indicating that there is no password in
NVRAM. If a password has been set, this prompt is displayed:
Please enter the password:
If the password entered matches the password in NVRAM, when the prompt is redisplayed
the console is no longer in secure mode and all console commands can be performed during
the current console session.
NOTE: If you enter the login command when a halt assertion exists, the command fails,
even if you enter the correct password.
If You Forget the Password
You can clear the password by using the local console terminal (not VGA monitor) and the
RMC.
From the Local Console Terminal
If you forget the current password, use the login command in conjunction with the RMC
halt in/out commands to clear the password, as follows:
1. Enter the login command:
>>> login
2. When prompted for the password, enter the RMC and issue the halt in command, press
the Return (Enter) key.
3. At the SRM prompt (>>>), enter the clear password command, then enter the RMC
and issue the halt out command.
The password is now cleared and the console cannot be put into secure mode unless you set
a new password.
