1. Internal cascading cables are bundled and attached with labels. When installing subracks during capacity expansion,
connect the internal cascading cables to corresponding ports on boards according to the figure below.
2. If four housekeeping alarm outputs are required, connect ALMO1 or ALMO2 in a subrack to the external centralized
alarm system; if eight housekeeping alarm outputs are required, connect ALMO1 or ALMO2 and ALMO3 or ALMO4
in a subrack to the external centralized alarm system.
