Display screen and controls

When the unit is powered, the display screen displays a menu or a dialog.

Each menu or dialog includes onscreen navigation labels that appear at the bottom of the display screen, on either side next to the display navigation buttons. Press the button next to the label to perform the action specified by the label.

To go back to the previous dialog or menu screen, use the navigation button to the left of the screen. To confirm a dialog value or select a menu option, either:

  • Press the navigation button to the right of the screen.

  • Touch the Select button.

Touch wheel

Use the touch wheel to changes values or move the cursor on the display screen. To confirm a value, touch the Select button.

Menu screens

You can access menus from the display screen.

Menus are displayed as a list of selectable options. An onscreen arrow points to the currently selectable option. If the menu has more than four options, an arrow indicates the direction in which more options are available.

To select a menu option:

  1. Move the indicator arrow up or down with the touch wheel.

  2. When the indicator arrow points to the option you want to select, either:

    • Press the navigation button to the right of the screen (labeled onscreen as SELECT).

    • Touch the Select button.

At the top right of the display screen, a number sequence indicates the path to the current option. The last digit of the sequence shows the location of the menu you are currently viewing. The top level menu has no numbers, but when you select the System menu, the number 1 is shown.

The preceding digits in the sequence show the position of each option in turn that was selected in previous menu screens to reach the current menu. For example, the sequence 1-2 shows that the indicator is on the second option of the menu that was reached by selecting the first option on the top-level menu.

For a map of the menu screens, see the Installation Guide.

Dialogs

For some tasks, a dialog is displayed onscreen. When the dialog opens, the cursor is in the first field. To change and then enter values:

  1. Use the touch wheel to change the displayed value of the fields.

  2. Touch the Select button to enter the displayed value and move to the next field in the dialog.

Repeat the procedure to enter all necessary values in the dialog.

Information display

When you use a dialog to request information (for example, a log or details of a key), there is often too much information to display onscreen. In such cases, only the first part of the information is displayed.

To view the rest of the information:

  • Use the touch wheel to scroll the displayed information in the direction indicated by the onscreen arrows.

  • When an Options label is displayed, press the right-hand navigation button to see a menu of navigation options. You can normally choose to go to the top, to the bottom, or to a specified line in the display.

The numbers of the lines currently being displayed onscreen are shown at the left of the screen. They are followed in parentheses (( )) by the total number of lines available for display.

Using the front panel controls

You can use the front panel controls to configure the unit and to perform other tasks described in this guide. When the unit is working over the network with another computer (a client computer), you can program and control the unit as if it were part of the client computer.

If the unit is powered down while you are logged in, you are logged out automatically.

Start-up information

When you turn on power to the unit and it has completed its initialization, the lower part of the display screen shows basic start-up information about the unit.

There is a series of start-up information topics available. By default, the first displayed topic is the current System time. Use the touch wheel to view the other start-up information topics.

Administrative control of the unit

You can view and control the status of the unit by using the front panel controls and menu options.

Tasks Action

Understand and control the power status of the unit

Use the Power button to power up the unit.

If the Power button is not illuminated, the unit is not powered. The Power button flashes intermittently as the unit powers up. It also flashes when the unit is in standby mode. For more information about the Power button, see the Installation Guide.

Control access to the unit

You can control access to the menus on the unit and the Power button on the front panel by using System > System configuration > Login settings.

When UI Lockout with OCS has been enabled, you must log in with an authorized Operator Card before you can access the menus. You can still view information about the unit on the start-up screen. When you are logged in, you can log out and leave the unit locked.

When UI Lockout without OCS has been enabled, you cannot access the menus, but you can still view information about the nShield HSM on the start-up screen. The only way to disable this setting (apart from returning the HSM to factory state) is to push an updated configuration file to the nShield HSM. See About user privileges and ui_lockout for more information.

Power button lockout can be enabled and disabled independently when UI Lockout allows access to the menus.

Unlock the unit

When UI Lockout with OCS has been enabled and you have logged out, the display screen displays the label Login next to the right-hand navigation button. Press the right-hand navigation button, then insert an Operator Card that has been authorized for login, and follow the onscreen instructions.

Log out of the unit

Select Logout.

This option is not available if UI Lockout with OCS has not enabled.
