11. as viewed when installed in a backplane The ENIU is referenced for configuration and application logic by the leftmost slot occupied by the entire module not by the slot the physical connector is located in For example if the ENIU has its physical connector inserted in slot 3 the module occupies slots 2 and 3 and the ENIU is referenced as being located in slot 2 The ENIU may be located in slot 0 with its connector in slot 1 The ENIU cannot be located in slot 11 of a 12 slot backplane or in slot 15 of a 16 slot backplane because its connector cannot be installed in the slot reserved for an expansion module 3 When migrating a Series 90 30 ENIU system to a PACSystems RX3i ENIU maintaining the slot 1 location of the ENIU means that only a singlewide power supply may be used in slot 0 Either DC power supply can be used IC695PSD040 or IC695PSD140 Therefore if the application must maintain a slot 1 ENIU and uses an AC power supply the RX3i system must have the RX3i AC power supply located in a slot to the right of the RX3i ENIU in slot 1 Locating the ENIU in a Slot Other than 1 Before deciding to place the ENIU in a slot other than slot 1 it is important to consider the possible application migration issues that could arise as explained below Application Program For Service Request 15 Read Last Logged Fault Table Entry and Service Request 20 Read Fault Tables the location of ENIU faults is not the stan
