2.2.2 Install the L351 in a UCS Model 1002 or Standalone Enclosure

Insert the L351 into an unused slot. Slide the L351 into the rails and push it firmly into the
backplane, then tighten the captive screw. If you encounter resistance, pull it out and check that no
connector pins are bent. If you encounter more difficulty, contact Canoga Perkins at (818) 718-6300
for technical assistance.

Note: The L351 is hot-swappable and can be inserted or removed without disrupting data transfer

in other modules in the chassis.

2.3

Install the Cables

The L351 uses both electrical and fiber optic cables. Electrical UTP cables connect to the User Port.
Fiber optic cables connect to the Extension port. Dirty optical connectors are a common source of
link loss or attenuation problems, especially for single mode fiber (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.

Follow these steps to install the cables:

1. 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.

2. 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.

3. Plug in the optical cables:

• If you have a single fiber connector (BIDI), plug the cable into a pair of L351s, one at 1310

nm wavelength and the other at 1550 nm wavelength.

• If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation.

Caution:

To protect the Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.

4. Plug the UTP Ethernet cable with RJ-45 connector into the User port on the front of the L351.

5. Label each cable and connector with a signal name and direction.

2.4

Measure Fiber Link Attenuation and Transmit Power

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, reference Chapter 5.
