Liebert STS2 Touch Screen Display

13.2.1 Security
Because the Liebert STS2 Color Graphical Display provides access to various configuration and
monitoring choices, a password or key lockout switch may be used to protect access to certain
changes, including:
• Change configuration settings.
•Clear logs.
• Make a source transfer.
• Reset an alarm.
Without entering the password or enabling changes with the key lockout switch, you still can:
• View the display, including the mimic, status and event help.
•View logs.
• View the startup and bypass procedures.
• Use the SILENCE button to turn off the audible alarm.
Using the Optional Key Lockout Switch
An optional key lockout switch for the Liebert STS2 enables or disables the ability to make changes
on the Liebert STS2. The key lockout switch is mounted on the front door. See Figures 8 through 10
for location of the key lockout switch.
• To disable the changes, turn the key to the top of the switch, toward the closed padlock.
• To enable changes turn the key to the horizontal position, toward the open padlock.

Using the Password
If the unit is not equipped with a keylock, a password is required when you attempt to:
• Save changes in the CONFIG menu choices.
• Transfer sources.
• Reset active alarms.
•Clear logs.
When a password is requested, a keyboard is displayed on the touch screen. After you enter the
password, select OK.
The password is case-sensitive. Password access times out after ten (10) minutes, and must be
re-entered to save changes. The time-out period cannot be changed.
To set or reset the password:
1. Select SYSTEM SETTINGS from the CONFIG menu.
2. Select SYSTEM ID form the SYSTEM SETTINGS menu.
3. Click PASSWORD.
A keyboard is displayed.
4. Enter a password.
The password must be four (4) alpha-numeric characters and is case sensitive.
5. Click OK.
