9.5.3 Replacement of Nearside Indicator Board
The Nearside Indicator board is used in two variations of Node, namely Nearside Indicator and the
Nearside Combined. In most cases, the Nearside Indicator Board can be hot swapped as part of a
maintenance procedure.
The process of removal and replacement is similar in both cases.
1. Remove power and communications by disconnecting the ByPass connector. In the case
of a Combined Nearside there are two ByPass connections, one of which will be to the
Wait/PDU Board. In this case both connections will need to be un-made.
2. Remove any other additional connections (e.g. Spur or Digital IO)
