TAU INSTALLATION AND TESTING

Summary: This procedure provides instructions for installing the Test Access Unit (TAU) in the chassis and verifying that it is functioning properly. The TAU requires no provisioning or periodic maintenance.

Caution: Modules can be damaged by electrostatic discharge (ESD). Before handling any modules, ESD protection must always be used. An ESD grounding post is located on the chassis for connecting the ESD wrist band. Ensure that all modules removed from the equipment or not installed, are properly stored in anti-static packing material. When working with modules, always place the module on an electrically-grounded, approved, anti-static mat.

Note: For information about installing and testing the TAU, which is used with MPU Software Version 5.3, refer to the Soneplex Test Access Unit Installation Instructions manual, listed under Related Publications at the beginning of this manual.

1.Remove the TAU from its protective packaging.

2.Insert the TAU into the full height chassis slot labeled TAU (as shown in Figure 574-1) until it reaches the backplane connector.

3.Using the ejectors, fully seat the TAU in the chassis. A moderate amount of force may be required to properly seat the module in the backplane connector.

4.Did the STATUS indicator light green?

•If Yes, you have completed this procedure.

•If No, replace the TAU and return to Step 1.

Stop! You have completed this procedure.
