Each input within the housekeeping rack is reported as an integer. In general, the application engineer
will not normally require these inputs. They are provided to aid fault finding and diagnosis and may be
used for reporting and display purposes. If a slice is Fatal, then all reported housekeeping inputs are
set to zero.

Table 14 Rack 8: INFO descriptions
The active module chassis and slot numbers indicate the position of the currently active module.
These values will change to match the primary or secondary module position, depending on their active
status, i.e. active/standby changeover will “swap” the values for the active module chassis and slot
number channels with those in the standby module chassis and slot number channels. The chassis
and slot numbers are set to zero if the module is not present.
The Active and Standby module healthy channel is returned as an integer, however only the least
significant bit is used. A value of 0 indicates that a fault has been detected, a non-zero value indicates
that the module is healthy.
