The liquid crystal display, or LCD panel, provides the ability to control the unit without attaching a serial or network cable. The LCD panel provides menus with options that provide the ability to configure certain features on the system. The following menus are available on the LCD panel.
Information menu
Use the Information menu to find information about using the LCD and its functionality.
System menu
Use the System menu to reboot, netboot, or halt the unit. This menu also has options for setting the properties of the management interface (MGMT) and the serial port.
Screens menu
Use the Screens menu to set up the informational screens you would like the LCD to cycle through. The information screens include system status, statistics, and system alerts.
Options menu
Use the Options menu to configure the properties of the LCD panel.
You can configure the LCD panel to meet your needs. The following section describes how to perform a number of tasks with the LCD panel:
Normally, the screens cycle on the LCD at a constant rate. However, you can push the Check button to toggle the LCD between Hold and Rotate modes. In Hold mode, a single screen is displayed. The Rotate mode changes the screen displayed on the LCD every 4 seconds.
Press the X button to put the LCD panel in Menu mode so you can access the menus. The buttons Left Arrow, Right Arrow, Up Arrow, and Down Arrow are only functional when the LCD is in Menu mode. For more information about using the LCD menus, see Navigating through the LCD menus.

Press the X button, then use the arrow keys to navigate to the System menu.
Hold the X button for 4 seconds to power down the unit. We recommend that you halt the system before you power down the unit in this manner. Halting the unit puts the chassis into a powered on, but quiet state where the LCD has power and its keypad is dimly lit, but everything else is off. Simply pressing the green Check button again powers the unit back on.
The system is designed to remember the state of the chassis soft power state even when the AC power is removed, and to restore that state when AC power is reapplied. If you power off the chassis using the Check button and then disconnect the power cord, the power state of the chassis returns to the soft powered off state when you reconnect the power cord.
Press the Check button to clear any alerts on the LCD screen. You must clear any alerts on the screen before you can use the LCD.
After you put the LCD in menu mode, use the Left Arrow, Right Arrow, Up Arrow, and Down Arrow buttons to select menu options. There are four menu options:
You can use the Information menu to access help pages about using the LCD panel functionality. You can also find more information on what different LED activity means, and the failover state of the unit in a redundant system. The following table, Table 3.1, shows the options available on the Information menu.

The System menu provides various options for rebooting, halting, or netbooting the hardware. This menu also provides options for configuring the network on the management interface. The following table, Table 3.2, lists the options available in the System menu.

You can use the Screens menu options to view various statistics and information about the system. The following table, Table 3.3, lists all the general information screens. You can use the Check button to place a check mark next to the name of the screens you would like to appear when the screens cycle.

TMMStatScreen (Statistics)
You can use the Options menu to adjust the display properties of the LCD panel. The following table, Table 3.4, lists the options available on the Options menu.
Use the Check button to turn on (checked) or off (unchecked) the heartbeat displayed on the LCD screen. This heartbeat displays if the SCCP is running on the system. This heartbeat does not affect the failover mechanism of the system.
