HP 3000 Enterprise Virtual Array - Manual (Page 79)

Disabling the audible alarm
CAUTION:
Disabling the audible alarm increases the potential of damage to equipment from a reported but
unobserved fault. HP does not recommend disabling the audible alarm.
Disabling the audible alarm affects only one enclosure. This action does not affect condition report
displays on the EMU alphanumeric display or the Command View EVA GUI.
To disable the alarm:
1. Press and release the bottom push-button until the alphanumeric display is Au.
2. Press and hold the top push-button until the alphanumeric display is a Flashing on (Audible Alarm
On).
NOTE:
When the alarm display is flashing, pressing and holding the top push-button causes the
display to rapidly change between on and oF.
Pressing and releasing the top push-button causes the display to select the next state.
3. Press and release the top push-button to change the display to a Flashing oF (Audible Alarm Off).
4. Press and release the bottom push-button to accept the change and display Au. The bottom
push-button LED is now On.
NOTE:
A disabled audible alarm (the bottom push-button LED is On) cannot sound for any error
condition. All errors will be displayed on the Command View EVA GUI and the EMU
alphanumeric display. HP recommends that rather than disabling the audible alarm,
you use the mute function (see How to Mute or Unmute the Audible Alarm ). When you
use the disable function, you should enable the audible alarm as soon as possible (see
How to Enable the Audible Alarm ).
Using the enclosure number feature
This section provides a general description of the purpose, function, and operation of the EMU enclosure
number (En) feature.
En description
In a single rack configuration, the En is a decimal number in the range 00 through 14, which is
automatically assigned by the enclosure address bus.
NOTE:
Your storage system may use an enclosure address bus higher than 14 if your Enterprise supports an
optional expansion cabinet.
By default, the two-character alphanumeric display shows this number. Pressing the bottom push-button
changes the display to En, the En display mode.
When the display is En, pressing and releasing the top push-button displays the enclosure number.
