The CAB front panel LEDs can be remapped to indicate alarm status to assist in
fault finding, particularly before connection of the Horizon
macro site to the
network. Operation of a dip switch (SW 4–5) and resetting the CAB causes the
front panel LEDs to illuminate when the alarm is clear.
The CAB front panel LEDs are remapped as shown in Table 4-3
