9 Pull the upper locking device away from the faceplate on the card and
press the lower locking device downward and insert the card firmly into
the backplane connector. Press the upper locking device firmly against
the faceplate and press the lower locking device upwards to latch the card
inside the module.
10 Set the ENB/DIS switch on the Fibre Superloop Network card to ENB.
The Fibre Superloop Network card automatically starts the self-test.
11 Observe the red LED on the front panel during self-test. If it flashes three
times and stays on, it has passed the test; go on to step 13. If it does not
flash three times and then stays on, it has failed the test. Pull the card
partially out of the module and reinsert it firmly into the module. If the
problem persists, troubleshoot or replace the Fibre Superloop Network
card.
12 Connect the SDI/System Monitor cable and the fibre-optic patchcords to
the faceplate connectors of the replacement Fibre Superloop Network
card.
13 Enable the Fibre Superloop Network card by logging in to the system
terminal, loading the Network and Peripheral Equipment Diagnostic
Program LD 32, and executing ENLL loop, where loop is the actual
loop number of the Fibre Superloop Network card.
14 Tag the defective card(s) with a description of the problem and prepare
them for shipment to your equipment supplier's repair depot.
