Smart module installation
To install the SM-SDR-2400 smart module, follow these steps:
1. Disconnect power from the LMS-2450-ME-100.
2. If you are replacing an existing smart module, remove all connections from any ports.
3. Unscrew the four captive screws on the existing module or blank plate.
4. Remove the module or blank plate.
5. Slide the new module into the empty bay, as shown below. The sides of the PCB rest inside the
guide rails in the bay.
6. Push the module in gently until it seats. When seated correctly, the module faceplate is flush with
the chassis faceplate.
7. Tighten the four captive screws on the module.
8. Power on the LMS-2450-ME-100.
9. After the chassis startup sequence, the PWR LED on the module turns green.
The module is installed and ready for use.
Tip: The module fits very tightly in the bay. If the module is difficult to insert,
simply straighten the module and try again.
