turning fcd-2 on
一、to turn fcd-2 on:
·set the rear power switch to on.
fcd-2 performs the self-test: observe the front panel indications.
during the self-test, fcd-2 displays the current software version in the format x.y:
after successfully completing the self-test, fcd-2 switches to the default display-alarm buffer.
if fcd-2 fails the self-test, you will see self test failed in the second row. in this case, fcd-2 must be repaired before it can be used again.
if the configuration data stored by fcd-2 is corrupted, the database cks err alarm message is generated. in this case, you will have to load the default configuration.
二、to load the default configuration:
1. display the alarm buffer header.
2. scroll until you see the database cks err message.
3. press enter to load the fcd-2 default settings
the default settings are listed in table 3-2, table 3-3, table 3-4 and table 3-5.
you can verify the fcd-2 configuration as explained in the following section. if the configuration does not require modification, fcd-2 is ready for operation immediately after self-test is completed. for information how to change the configuration, refer to section 3.6.
checking the current operating configuration
before performing the procedure below, review section 3.4 for the fcd-2 configuration parameters.
during the following procedure, do not press the enter push button, to prevent accidental change of parameters.
normal indications
lcd
the top row shows alarm buffer.
1 during the normal operation, the second row should show empty (no alarm messages).
2 if the alarm buffers contain alarms, you will see scroll alarms in the second row.
refer to chapter 5 for the alarm types explanation, and for the instructions on displaying and clearing the alarms.
leds
during the normal operation, all the red indicators are off.
1 the transmit activity of the local user data channel is indicated by the td and rts (or c) indicators.
2 the receive activity of the local user data channel is indicated by the rd and dcd (or i) indicators.
if any of the two sync loss and/or test indicator lights, data transfer is interrupted.
1 the test indicator lights when a test is activated. the test type can be displayed by entering the test options (see chapter 5) if the test is activated from the local fcd-2.
2 the loc sync loss indicator lights when local loss of synchronization occurs.
3 the rem sync loss indicator lights when remote loss of synchronization occurs.
monitoring the fcd-2 performance
fcd-2 continuously measures the diagnostic performance data. the diagnostics data is available under diagnostics.
for explanation of the measured bpv, oos and crc-4 events, refer to chapter 5.
