Clearing alarms
Select Link or Local or Remote > Alarms > Clear Alarms
MHSB Command
If a MHSB switchover event occurs, the OK LED on the front panel changes to orange.
To clear the MHSB switchover alarm:
Select Clear Switched Alarm from the MHSB Command drop-down list and click on Apply.
Image Table Alarm
An image table alarm appears if a problem occurred during the boot process which may have left the
image table in an inconsistent state.
To clear the two types of image table alarms:
ƒ The alternate image table alarm: this indicates that a backup image table has been used. This will
match the actual image table unless immediately following a software upgrade.
ƒ The default image table alarm: this indicates that the image table has been rebuilt from defaults. In
some circumstances this will mean that an incorrect build of software is running on the terminal.
In either case, in addition to clearing the image table alarm, you should verify that the active images in
the image table are correct for their software release.
