Canoga Perkins 9161, User Manual

Page: 12 / 54

Cabling for the 9161 includes the serial cable to the Terminal port, the Ethernet cable for a UTP port,
and the fiber optic link to the Tx and Rx ports.
5. Plug the serial cable into the SLIP or Terminal port on the rear panel and your PC. For the
pinouts, see Chapter 5, Specifications.
•
The EIA 232 Terminal port provides serial access to the management software.
•
The SLIP port provides serial or modem access to the management software.
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.
6. 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.
7. 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.
8. Plug in the optical cables with Tx to Rx, Rx to Tx orientation.
Caution: To protect the Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.
9. 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.
This chapter describes the hardware features and functions of the 9161.
Power-Up, Hardware Functions, and LEDs
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 LNK, Rx and Tx LEDs for both ports light green or blink green when they transmit or receive
data.
The LEDs show the system and port conditions. The STA and CFG LEDs show the management
conditions; see Table
Error! Reference source not found. . Each interface module includes from
two to six LEDs; Table Error! Reference source not found. lists all possible LEDs. For details
about the LEDs, see your interface module and Tables Error! Reference source not found. and
