Expansion TDM Submodule Installation

If you want to add a TDM submodule to an Audio module that you already

have, or you decide that you want to put the TDM submodule on an AES

Digital Audio module instead of an Analog Audio module, or vice versa,

use this installation procedure.

1. Inspect the TDM submodule.

2. Lift the ejector tabs on the front of the Audio module.

3. Pull the module gently to disengage it from the backplane.

4. Slide the module out of the frame.

5. Use anti-static precautions to protect the module.

6. Place the module on a padded surface, so that the back side of the

module is facing up. See Figure 54.

7. Remove the four nuts from the TDM submodule, set aside.

8. Seat the TDM on the Audio module by aligning the connectors on the

back of the TDM submodule with the connectors on the back of the

Audio module. See Figure 54, the four plastic pins on the TDM

submodule will match up with the four holes on

the Audio module.
