CANOGA PERKINS 9160 10 Gigabit Ethernet Network Interface Device - Manual (Page 12)

Dirty optical connectors are a common cause of link loss or attenuation problems, especially for SMF.
Clean the connectors before plugging in a cable and whenever there is a significant or unexplained
light loss. To prevent contamination, always install protective dust covers on unused fiber optic
connectors.
7. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free, isopropyl
alcohol pad from a fiber cleaning kit.
8. Use canned air to blow any dust out of the female fiber coupler.
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
9. Plug in the optical cables with Tx to Rx, Rx to Tx orientation.
Caution: To protect a UTP Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.
10. If your 9160 includes a UTP port, plug in the UTP Ethernet cable with RJ-45 connector.
11. Label each cable and connector with the signal name and direction.
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 4.
Power-Up, Hardware Functions, and LEDs
During the initial power-up sequence, all LEDs light amber. When start-up is complete and data is
transmitting normally across the link, the MGR, FAN, and power LEDs light green and the Rx and
Tx LEDs for all ports light or blink green when they transmit or receive data.
The LEDs on the front panel show the system and port conditions. The MGR LED shows the
management conditions; see Table 1. Each interface module includes from two to six LEDs; Table 2
lists all possible LEDs. For details about the LEDs, see your interface module and Tables 1 and 2.
