Faceplate
The faceplate provides two HDB44 connectors (J1, J2), one 4-pin Molex connector (J3), and two LEDs:

J1, J2 Connectors
The 32 digital I/O signals are routed to both J1 and J2 connectors. This allows, for example, splitting the input and output signals into two different cables.
If the harnessing uses only one connector, it is recommended to use J2 (bottom one).
The connectors' pin assignment is detailed in the /wiki/spaces/OICSI/pages/28574364

LED Definition
| LED Name | LED Behavior | Definition |
|---|---|---|
Power | Off | No power present on module (either from SLSC Interface or external power) |
| Solid Green | Power OK State | |
| Blinking Red | Module Fault State | |
Ready | Off | The module is not powered or in Rdy/Rst# is driven low by the chassis. |
| Solid Green | Module in the default configuration, recognized by the chassis and ready to configure. (The Rdy/Rst# signal has been pulled high by the chassis.) | |
| Blinking Amber | The module is active (in a non-default configuration and/or communicating with the chassis). |
