2.1 Restrict Physical Access with Barriers or Set Log-In Codes
NOTICE
Risk of unauthorized changes to UPS operational settings. Can cause equipment damage.
Because a UPS such as the Liebert
®
EXL
™
S1 is usually installed in areas that restrict physical access, the
Touchscreen Control Panel does not, by default, require a PIN to change UPS settings and operations.
If physical access cannot be restricted with barriers and identity cards, PIN codes may be set in the
Touchscreen Control Panel to prevent unwanted changes to the Liebert
®
EXL
™
S1.
The Touchscreen Control Panel has four possible access levels—Observer, Operator,
Administrator and Service—each with different levels of authority. The Service level, which
permits configuration changes, is the only level that, by default, requires a PIN.
The default access level for the Touchscreen Control Panel is Administrator. When a PIN is set for
the Administrator, the control panel opens at the Operator level.
To set or change a PIN, refer to 3.1 - Log In to the Touchscreen Control Panel.
