13. Use canned air to blow out any dust from the female fiber coupler.
Caution:
To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
14. Plug in the optical cables with Tx to Rx, and Rx to Tx orientation. For redundancy, use primary
to primary and secondary to secondary orientation.
15. Label each cable and connector with the signal name and direction.
16. For cable connections to other modules in the chassis, see the appropriate user manual for details.
Canoga Perkins recommends that you determine and record link attenuation and transmission power
before starting normal link traffic. The attenuation factor and transmission power identify potential
problems with links near the lower limit of receiver limitations.
For details on link attenuation and transmission power, see Chapter 5.
Power Up and Front Panel Functions
During the initial power-up sequence, all LEDs light amber. When start-up is complete, the setup and
installation are correct, and data is transmitting normally across the link, the STA LED lights green
and the CFG, TST, LOS, and CLS LEDs are off. During normal operation, the LED colors change
according to system and port conditions. The STA, CFG, and TST LEDs show the module condition.
The LOS and CLS LEDs show the electrical and optical signal conditions. Table 3 shows the LED
states for various conditions.
