Black Box 5000 manual 166

Multiserver 5000

LCD BLINKING BACKLIGHT

When working in the menus, should the backlight begin blinking, it means that there is an alarm message. You can exit to the top level (Banner Message Display) and read the message or just clear the blinking backlight.

This is how to clear the blinking backlight: From the Banner Message Display, press the right arrow, then press the down arrow three times. The display will read Clear Latched Alarm. Press the EXEcute key and the blinking will stop. To return to the top menu, press the up arrow until the Banner Message Display appears.

Another way to clear the display is through the Commands Facility Main Menu by selecting option 9, Clear Alarm Displays.

KEYPAD RESET

The Multiserver can be manually reset from the keypad by pressing the two outside keys at the same time and holding them for two seconds. This is a hardware reset (warm start), and the current configuration will remain unchanged, except for the time and date. The time and date are lost during this reset. (A warm reset accessed through the LCD/Keypad Administration Menu does not erase the date and time.) This reset does not require a password.

Within the Administration Menu of the LCD, there are four reset options: warm start (current configuration), cold start (default configuration), link reset, and channel reset. These four reset options can be protected with a keyboard password (see Section 11.5, Network Security).

LCD/KEYPAD PASSWORD PROTECTION

The LCD/keypad password protects all the administrative, diagnostic, and configuration functions, allowing access only to review the alarm and status messages in the system message log.

The password may be a series of up to eight up, down, left, and right arrows, followed by the EXEcute key. This sequence is entered in the Command Facility as U, D, L, R characters followed by a <cr>. For example, after configuring UUDL<cr> as the password, you would enter 2 up

arrows, a down arrow, a left arrow and EXEcute at the LCD/Keypad password prompt. Do not use commas when configuring. If no password is required, enter a space during the password configuration.

The default configuration is for no password. If you wish to configure a password, see Section 11.5, Network Security, for more information.

The following LCD/keypad functions are not password-protected:

•Review system messages log function

•Banner message display

•Hardware reset.

TIMEOUTS

•Backlight Timeout. The LCD backlight will remain lit for five minutes. After that time, if there is no keypad activity, the light will go out. To relight the display, press any key of the keypad.

•Menu Timeout. There is a five-minute timeout feature on the menus. If there is no activity on the keypad within a five-minute period, the system will time out and return to the Banner Message Display.

NOTE: There is one exception. When the LCD is in a monitoring mode (during a diagnostic test), the menu will not time out.

•Event and Alarm Messages Display Timeout. Current event and alarm messages will be displayed at the Banner Message Display as long as there is activity at the keypad. If there is no keypad activity for two minutes, the message will time out and no longer be displayed at the LCD. The messages in the system log queue will not time out; the queue will always display the most current ten messages.
