Figure 101. Wait/PDU PCB Removed
1. Fitting is the reversal of removal. In the case of a Combined Nearside with two ByPass
connections, ensure the left-hand ByPass connection is to Wait/PDU and the right-hand ByPass
connection is to Nearside (no crossover of ribbon cables).
Note:
For a single Node, the process to acknowledge an update does not require prior knowledge of
the Serial Number. However, it is good practice to note the New Serial Number and update any
backups of the Design Layout (paper or Electronic). If multiple nodes are being replaced, then
the Serial Number will need to be noted for configuration update.
1. At the controller, in the Fault Table, the User is expected to ‘Acknowledge’ the change in Node
and then press the L3 button to confirm. Note: The use of the ‘Release’ Button is not required.
10.5.3. 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.
•
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.
