Description
For example, if ALMO1 is used
to output alarm signals, ALMO2
can be cascaded to ALMO1 on
another subrack.
The OptiX OSN 8800 universal

platform subrack provides four
alarm outputs. Defaults of the
first three are critical alarm,
major alarm, and minor alarm.
The other one are reserved.
Alarm outputs can be cascaded.
For information about interface
cables, see 33.2.1 Alarm Output
Interface Cable.
External alarm signal input function
is designed for requirements when
the alarm signals of the external
systems (such as the environment
monitory) need remote monitoring.
The OptiX OSN 8800 universal
platform subrack provides four
alarm inputs. The severity of the
four alarms can be configured to
cooperate with the external system
to implement remote monitoring of
external alarms.
For information about the interface
cable, see 33.2.2 Alarm Input
Interface Cable.
The LED displays the master/slave
relationships between subracks.
This subrack ID LED has the same
function as that on front panel of
the SCC board.
"0" indicates that the subrack

housing the EFI board is the
master subrack,
"EE" indicates that the subrack

ID is incorrect or the subrack ID
fails to be obtained.
Other values indicate slave

subracks.
For the values displayed on the
LED, see Figure 4-32.
