ECU-S
ECU-S is a new type of ECU introduced in Release 10.5.2 for ONS 15454 M6. The ECU-S module also
discovers and manages the inventory of the external shelf units. It also handles the multishelf management
connections and timing synchronizations. The ECU-S module available for the ONS 15454 M6 shelf is
15454-M6-ECU-S=. The ONS 15454 M6 ECU-S is backward-compatible with Release 10.1, 10.3, and 10.5.
However, there is a small difference in the port numbers detected. The details are listed in the section below.
Note The NCS 2006 ECU-S should not be used when the shelf is powered at –60V DC nominal input voltage.
The following figure shows the ONS 15454 M6 ECU-S connectors.

The ONS 15454 M6 ECU-S supports IEEE1588v2 PTP, time-of-day (ToD), and pulse-per-second (PPS)
inputs. To support high power USB devices, ONS 15454 M6 ECU-S provides a current of 500 mA to each
of the ports. The IMPROPRMVL alarm is raised in CTC when the ECU-S is removed from the NCS 2006
shelf.
