4 • Alarms Model LRA2900A RAS Administrators’ Reference Guide Introduction The access server has an extensive alarm reporting system which enables users to conﬁgure, monitor, and test major and minor alarms. The alarm system can be set to notify if equipment fails (for example, a power supply failure) or if a T1/E1/PRI port malfunctions.
Page 48: Alarm Response Outputs
Model LRA2900A RAS Administrators’ Reference Guide 4 • Alarms The access server has three methods to notify of an alarm condition: • Front panel LED—The front panel ALARM LED has three states that indicate the presence and severity of an alarm. The states are: Off—No alarm present Solid—Minor alarm Flashing—Major alarm.
Page 49: Minor Alarm Syslog Priority (Minsyslogpriority)
4 • Alarms Model LRA2900A RAS Administrators’ Reference Guide Minor Alarm Syslog Priority (minSyslogPriority) Displays the SYSLOG priority of the minor alarm SYSLOG message. If the minimum priority for SYSLOG daemon (set under the System Log link) is less than this value, the SYSLOG daemon will receive the minor alarm SYSLOG message.
Page 50: Clear Alarm
Model LRA2900A RAS Administrators’ Reference Guide 4 • Alarms Clear Alarm Clicking the Clear Alarm button resets the alarm to a non-alarm condition. Clear Alarm resets Alarm Time to 0.0 seconds, and resets the Alarm Count to 0. Modify Response—Conﬁguring the alarm response system The alarm response outputs only effect external notiﬁcation via SYSLOG/SNMP as the front panel ALARM LED and the web administration pages will always indicate an alarm condition.

Page 163: Dlmi Window
13 • Frame Relay Model LRA2900A RAS Administrators’ Reference Guide DLMI window Each Frame Relay instance with the access server is known as the Data Link Management Interface or DLMI. The access server software currently supports one Frame Relay Link, or DLMI, on each of the T1/E1 WAN ports.
Page 164: Data Link Protocol
Model LRA2900A RAS Administrators’ Reference Guide 13 • Frame Relay The Frame Relay link is now available. The ﬁnal stage will be to conﬁgure PVCs and IP routing so they can use these new links. The following sections describe the additional variables on the DLMI window. Note Be careful not to change these variables unless your provider instructs you to do so.
