Installing the ONS 15454 M6 Shelf
You can upgrade to the NCS2006 ECU60-S from an older ECU (ECU/ECU-2/ECU-S) in the ONS 15454
M6 shelf. For more information, see
Alarm Connectors
The ECU modules, except for ECU-60V, have two SCSI alarm connectors that are used to connect ONS
15454 M6 to support external alarms. The alarm connectors provide dry alarm contacts and are similar to the
AIC-I card of the ONS 15454 shelf. The left alarm connector is used for TNC and TNCE relay contact,
including Alarm Cut Off (ACO) signal and Digital Input/Output (D-I/O) signals. The right alarm connector
is used for Digital Input/Output (D-I/O) signals. To export alarms from the ONS 15454 M6 shelf to a third
party device, use the output pins of either the right alarm connector or the left alarm connector.
When external controls are not provisioned, 14 external input alarms are available. Input alarm 11 and input
alarm 12 are available on the left side connector; input alarm 13 and input alarm 14 are available on the right
side connector.
When external controls are provisioned, only 10 external input alarms are available.
Note In a multishelf configuration, alarms on the subtended shelves cannot be extended through the node controller.
Note ECU60-S does not support alarm connections.

Passive Unit Inventory Interfaces
The passive unit inventory interfaces (USB ports) are used to retrieve inventory information from passive
devices such as fiber trays, FBG DCU, patch panels, passive multiplexer or demultiplexer, and so on. There
are 12 USB ports on the ECU modules. The inventory details are displayed in the Inventory tab in CTC.
The USB 3.0 port delivers power to the fiber shuffle unit or the MPO-fan-out unit when they are connected
to the ONS 15454 M6 2006 ECU-S.
Note
The 12 passive inventory ports on the ECU modules are labeled 1 to 12. However, CTC represents the passive
inventory ports as USBP_SIDE_PORT, where SIDE can be A or B, and PORT can be any value from 1 to
12. For example, Port 1 on the left side of the ECU module is represented as USBP_A_1 and Port 1 on the
right side of the ECU module is represented as USBP_B_ 1. The left side of the ECU module is Side A and
the right side of the ECU module is Side B.
