LCD Display
This section describes the addition of LCD to Ivanti Policy Secure devices.
Overview of adding LCD for Ivanti Policy Secure
The addition of a LCD screen allows field technicians to quickly gauge the health of the system without logging into the device. The buttons on the LCD panel allow navigation through the display menus. The directional buttons are used to access the menu modes and find device information. The LCD can display two line of text. The below figure shows the LCD screen with navigation buttons.
LCD display is available for the PSA-7000 platform model only.
Modes Supported by the LCD
The LCD supports two modes namely the display mode (default) and the menu mode. Pressing any button in the display mode will change the mode to menu mode. If a user presses the cancel button, the LCD immediately changes back to display mode and shows the appropriate state. The LCD remains in display mode. If the LCD is in menu mode and the user does not press any button for more than two minutes, then the LCD changes back to display mode. The below figure shows the two modes supported by the LCD
Display Mode
The display mode describes the current state of the system, such as normal state or error conditions (e.g., fan speed and overheat). It represents the default status. The LCD goes into display mode after boot-up is complete. In display mode, the LCD is either set to NORMAL or shows a label that describes an error condition. If all systems are functioning normally, then the LCD shows NORMAL. The second line in the NORMAL state is used to show whether the appliance is configured as part of a cluster. The valid states in the display mode are Clustering OFF and Clustering ON.
Detecting Error Conditions in Display Mode
If more than one error condition is detected, all error conditions will be displayed in sequence with a 2 second pause before switching to the next one. All error conditions need to be cleared before the status returns back to the NORMAL state. Error conditions include:
- Overheat
- Fan Failure
- RAID Errors
If there are any error conditions, they are automatically shown on the LCD screen when it is in the display mode. The types of errors displayed are: Fan Failures, CPU overheating and RAID errors. If there are multiple errors they would be displayed in the order with a two second pause between successive displays.
The error message is automatically cleared when the underlying error condition is resolved. For example: the CPU overheat message disappears when CPU temperature is lowered. The user can enter the Menu mode at any point, even if an error message is being displayed.
Menu Mode
The menu mode is activated when the user presses any button. A single press of the button changes to menu mode and loads the last selected menu selection.
To view information in the menu mode:
- Press any button. This puts the LCD into menu mode.
- Press the right and left arrows keys to obtain the available system configuration data.
- View information starting with the Internal IP and moving in a clockwise direction.
- The menu screens loop back in a cycle.
- Press Cancel at any point to exit to display mode.
Any button, even cancel will put the user in the menu mode.
