Action Description

Action Meaning
A No action.
B Start action for fault clearance, if necessary change ce.
C Collect system-reports and inform system-specialist.
D Check LAN (HUBS) and cable, if necessary fix link. If the LAN status indicates a problem with a server, and this server has just a reload, restart or a similar action, the alarm is correct, because there is no server available at the moment. This error will be switched off by the system autonoumously when the connection can be established again. This is normally 2 minutes later. The alarm occures also when there is no server connected. In this case these alarms will be set by all EPM boards. It might happen that without actions at the server certain boards will set the alarm and reset it within 1 minute (toggleing alarms). If only a few boards behave like this it is no problem for e.g. the billing chain and not critical. Look for the billing alarms. This toggleing should be for less than 10 minutes, if the CE stays longer in this state, it has to be restarted.
