10.3.1 Reading Fault Status
This section describes how to read the fault status, using the OMT. If any fault
indicator on the RBS is on, then the fault status must be read.
Connect the OMT
1. Remove the lid from the OMT port on the IXU.
2. Connect the OMT cable from the PC serial port 1 to the OMT port on the
right-hand side of the IXU. If an extended OMT cable is connected to the
OMT port, then connect the OMT cable to the end of the extended OMT
cable.
