Enabling/disabling alarms via the internal DIP switch
In addition to the terminal settings, the IDSU internal DIP switch allows you to enable or
disable alarm messages out the control port. Switch 7 enables or disables alarm messages.
Switch 8 specifies whether, if alarms are enabled, they are output via the DCE control port
or via the DTE control port.
To access the DIP switch, see instructions for removing the side panel on page 16 .
Enabling/disabling
alarm messages
If you enable alarm messages they are output via the specified control port. If you disable
them, alarms are recorded in the Alarm History report, but they are not output as mes-
sages. The setting of this switch has no effect on SNMP trap output.
This switch can be overridden by the EAM/DAM commands. See your user’s guide.
Specifying the alarm
output control port If you are using a terminal connected to the DCE port, you normally want alarms output to
that port. The only time you might want alarms sent to the DTE port is when you are using
a modem connected to DTE or when you are using alarm dial-out. Alarm dial-out requires
that alarms be sent to DTE. For example, you might want the alarm dial-out to go an exter-
nal alarm device connected via the DTE port instead of to a terminal connected to DCE.
If you are using daisy-chaining, alarms must go to the same control port as the one being
used by the control device, terminal or modem. Alarm dial-out is disabled during
daisy-chaining.
This switch can be overridden by the DCE/DTE commands. See your user’s guide.
