HP 3000 Enterprise Virtual Array - Manual (Page 78)

• Correct all errors, thereby silencing the alarm until a new error occurs.
• “Mute,” or temporarily disable, the alarm by pressing and holding the bottom push-button. The
alarm remains Off until another error occurs, or until you enable (“unmute”) the alarm. When a
new error occurs, the alarm sounds and the push-button LED is Off.
Using the mute feature ensures that you are aware of the more severe errors and provides you with the
capability of correcting them promptly.
• Disable the alarm to prevent any error condition from sounding the alarm.
NOTE:
Disabling the alarm does not prevent the EMU alphanumeric display from displaying Er. Nor does it
prevent Command View EVA from displaying the error condition report.
When the alarm is enabled (on), the bottom push-button LED is Off.
Enabling the audible alarm
To enable 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 oF (Audible Alarm
Off).
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 on (Audible Alarm On).
4. Press and release the bottom push-button to accept the change and to display Au. The bottom
push-button LED is now Off.
Muting or unmuting the audible alarm
When there is an error condition, determine one of the following:
• The error does not require immediate corrective action.
• You cannot implement a correction (such as, you require a replacement element).
To mute the audible alarm :
NOTE:
Er is displayed in the alphanumeric display when an error condition is present.
1. Press and hold the bottom push-button until the LED is On.
A muted alarm will remain Off until a new condition report exists.
