ADCP-61-743 • Issue 3 • September 2004 2.2 Maintenance Installation (Existing System) Replacement of the RTAU module in existing IBBC shelves should follow normal maintenance procedures. Since a module has already been in service in the affected slot, the backplane pins will have been trained into alignment with subsequent replacement modules. If excessive resistance is encountered upon insertion, remove the module and inspect for misalignment or obstructions. This procedure assumes that
