The power supply circuitry for the equipment can constitute an energy hazard. Before you install or
replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can

Trouble-Clearing Procedures
This section list alarms alphabetically and includes some conditions commonly encountered when
troubleshooting alarms. The severity, description, and troubleshooting procedure accompany each alarm and
condition.
Note
When you check the status of alarms for cards, ensure that the alarm filter icon in the lower right corner of
the GUI is not indented. If it is, click it to turn it off. When you are done checking for alarms, you can click
the alarm filter icon again to turn filtering back on.
Note When checking alarms, ensure that alarm suppression is not enabled on the card or port.
Note When an entity is put in the OOS,MT administrative state, the system suppresses all standing alarms on that
entity. All alarms and events appear on the Conditions tab. You can change this behavior for the
LPBKFACILITY and LPBKTERMINAL alarms. To display these alarms on the Alarms tab, set the
NODE.general.ReportLoopbackConditionsOnPortsInOOS-MT to TRUE on the NE Defaults tab.
