Shutdown of Line Card Communication with CPM2
A Line Card may be temporarily removed from CPM2 polling for
testing and maintenance purposes; refer to “CPM2 Utility Modes”
for information on shutting down a line card. While in the shutdown
mode, the Line Card will retain up to 255 alarm messages in its
event buffer. When the Line Card is shut down, the “Trouble” light
will come ON and this message will be displayed:
DRL-MX – Line #0D
DRL-MX – Line #0D
DRL-MX – Line #0D

CPM2 Error; Display Alarm Messages
If the DRL-MX cannot detect CPM2 polling and there are no
alarm events in the event buffer, this message will be displayed:
DRL-MX – Line #0D
DRL-MX – Line #0D
DRL-MX – Line #0D
DRL-MX – Line #0D
DRL-MX – Line #0D

If alarm messages cannot be sent to the CPM2 because of the
error, the DRL-MX will display the oldest message which has
not been manually acknowledged. The “Alarm” light will FLASH
and the sounder will beep if the “Mute Buzzer” Option is
programmed as [00] or [01].
When a CPM2 Error is present, each alarm must be manually
acknowledged. Press the [ACK/FUNCTION] button to acknowledge
the alarm and silence the Line Card sounder. If several alarms
have been received but cannot be sent to the CPM2, they will
have to be individually acknowledged; when all alarms are
acknowledged, the Line Card sounder will be silenced.
Up to 128 alarm messages for the printer and computer will be
retained in the CPM2 event buffer. When the event buffer is full,
the oldest messages will be deleted as new events are recorded.
When the CPM2 Error condition is corrected, the alarm messages
in the event buffer will be transmitted to the CPM2.
