How the DL600E Unit Reports Alarms
For an alarm to be detected and reported, the alarm must be set to Enabled and
Block all Alarms set to No .
The local DL600E unit reports local alarm conditions to the device connected
to its Comm Port (such as a terminal, printer or modem).
If the remote Connection in Menu-8 is set to In-Band Communications , the
local DL600E unit also reports the remote alarm conditions.
Depending on the network management environment, the DL600E unit may
also send SNMP TRAP messages.
If the local DL600E unit is connected to a
modem
and an alarm occurs, the
DL600E unit causes the modem to
dial out
(if in
Menu-8 Alarm II
,
Connection
is set to
Modem
; valid telephone numbers are set in
Phone Number 1
or
Phone
Number 2
).
How Alarms Reports Are Displayed
Alarms are displayed
on a terminal
at the bottom of the screen when the
terminal is connected to the Comm Port and you are logged on, for example, a
carrier loss condition on the Data
P
ort displays at the bottom of the screen as
follows:
--Local ID :Oahu Data1 Carrier Loss Start: 07:17:37 Jan.08, 1994--
The alarm includes the unit
ID
, local or remote, type of alarm, start or end of
alarm condition and date and time. It remains on the screen until a new alarm
occurs or you select a new screen. When no alarm is present, a blank dotted
line appears:
