DLX INSTALLATION AND TESTING

Summary: This procedure provides instructions for mounting DLX modules in the half-height slots located in the middle of the chassis. A typical DLX installation consists of a DLX installed in a chassis and a channel bank at the other end. There is no protection for this signal.

Caution: Modules can be damaged by electrostatic discharge (ESD). Before handling any modules, ESD protection must always be used. Ensure that all modules removed from the chassis 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: When using DLX modules in a group, NEVER install ODS2 modules in any of the unused slots in the group.

1.Remove the module from the protective packaging if required. Refer to your work order and determine which DLX slots are to be used. DLX chassis slots are shown in Figure 521-1. Chassis slots 1-1 through 7-4 correspond to DS1 signals 1 through 28 as shown in Table 521-1.

Reference: TAD-106Access Identifier

2.Align module with the slots and slide module into the chassis. Using the ejector, press the DLX module into the chassis until it is properly seated.

3.Press LMPTST switch on the APU. Are all indicators lighted?

•If Yes, continued to Step 4.

•If No, replace DLX module and go to Step 1.

4.Repeat entire procedure for each DLX module.

Stop! You have completed this procedure.
