EDA 2530 Equipment Test and Alarm Checks
8.1
Equipment Test
This subsection describes the actions to be carried out to test the EDA 2530
equipment before it is connected to a network.
8.1.1
Optical Launch Power Test
This measurement should be taken at the optical distribution frame (ODF) if present,
but if not directly at the card optical transmitter output.
a.
Disconnect the Transmit optical fibre(s) of the unit being tested, then use an
optical power meter to measure the Transmit Launch Power from each port
of the unit under test.
b.
Check that the measurement is within limits, as specified in the TX Launch
Power Limits table below.

Unit Status Check
Check that the LCT screen display corresponds to the real status of the equipment.
i.e. that all the electronic units present in the equipment are properly displayed, and
that there are no inconsistencies between the actual status and the displayed one,
both for the alarms and the functional status of the units.
Right click on each unit and select
“Show Actual”
, then “Actual Card is ………..”
and “Slot Alarm Status:……” will be displayed.
