ODS2 MODULE FORCED SWITCH TEST THROUGH THE CRAFT INTERFACE

Summary: This procedure provides instructions for verifying that the force-to-protect feature of the ODS2 module is working. Both working (online) and protect (offline) ODS2 modules are tested.

Warning: Do not insert module edge connectors into the chassis connectors before connecting the optical fiber to the module. Exposure to invisible laser radiation may occur if the module edge connectors are allowed to connect with the chassis connectors before connecting the optical fiber to the module. Verify that all indicators are dark (off) and the module is not engaged with the chassis connectors before proceeding.

Warning: Verify that module is completely disconnected from the chassis connectors before removing the optical fiber from the module. Verify that the far end transmitter is off before proceeding. Exposure to invisible laser radiation from the optical fiber is possible if the far end transmitter is transmitting. Verify that all indicators are dark (off).

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.

1.Set up the chassis and a remote QFLC or QLX chassis, then perform end-to-end tests between chassis and the remote chassis.

Tests

2.Identify the offline ODS2 module of the working and protect pair to be tested. Its STATUS indicator is green and is the only illuminated indicator (its ONLINE indicator is extinguished).

3.Slide the offline ODS2 module part way out; this disconnects the offline module from the chassis and ensures that data passes through the online ODS2 module only.

4.Perform end-to-end test and verify error-free data.

Tests

5.Using the ODS2 module ejector, press the module into the chassis until it is properly seated.

6.Verify that the STATUS indicator on offline ODS2 module is green and its ONLINE indicator is extinguished.
