T1/E1 DACS Administrators’ Reference Guide
4 • Alarms
The T1/E1 DACS Multiplexer has four methods to notify an alarm condition:
1.
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.
Note
The POWER LED will flash if a power supply failure alarm is
present.
2.
Administration web page indication—The Alarms window of the administration page uses red highlight-
ing to indicate which items are in an alarm state (see figure 10).
Figure 10. Sample alarm indication
3.
SYSLOG/SNMP—For external notification, the DACS can be configured to send a SYSLOG message or
an SNMP TRAP to an external management host. To configure the alarm response for either SNMP Traps
or SYSLOG messages, click on the
Alarm Response
link (go to “Alarm Parameters” on page 33).
4.
Alarm Relay—Located on the rear of the chassis, the Alarm Relay is a 3-position terminal block. The
Alarm Relay may be configured to indicate when a major alarm, a minor alarm or both major and minor
alarms occur. It may also be disabled. The 3-position terminal block numbers its pins from 1 to 3 from left
to right. When no alarms are indicated, pins 1 and 2 are normally closed and pins 2 and 3 are normally
open. Upon the occurrence of an alarm—the type is configured as major, minor, or both—pins 1 and 2 are
open and pins 2 and 3 are closed.
Besides enabling a user to view current alarm status, you may manually generate an alarm as a test and clear the
alarm time and count variables. The Alarms main window also contains links to the following:
•
Modify Response—for configuring how the Alarm Response Outputs for notifying administrators of an
alarm (see “Alarm Parameters” on page 33)
•
Modify Alarms—Clicking on this link takes you to a window where you can configure the importance or
severity of each individual alarm. The severity of the alarm type may generate a minor, major, minor self-
clearing, or major self-clearing alarm. Any alarm type may be disabled. (“Modify Alarms—Configuring
alarm severity levels” on page 35)
