Cabling the Cisco RFGW-10 UEQAM
Use a magnifying glass or inspection microscope to inspect the ferrule at an angle. Do not look directly
into the aperture. Repeat the process if any contamination is detected. The connectors used inside the
system have been cleaned by the manufacturer and connected to the adapters in the proper manner. The
operation of the system should be error free if the customer provides clean connectors on the application
side, follows the previous directions, and follows these guidelines:

Cabling the TCC Card
This section describes the procedure for cabling the TCC card.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are
improperly handled, can result in complete or intermittent failures. The AC-input power shelf and its AC
power modules contain a printed circuit card fixed in a metal carrier. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the cards from ESD, use an antistatic strap each time you handle the modules.
Following are guidelines for preventing ESD damage:

Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms.

Clean the connectors using either a CLETOP cassette cleaner (Type A for SC connectors and Type
B for MT-RJ connectors) or lens tissues before connecting to the adapters. Use pure alcohol to
remove contamination.
Do not clean the inside of the connector adapters.
Do not use force or quick movements when connecting the fiber optic connectors in the adapters.
Cover the connectors and adapters to keep the inside of the adapters or the surface of the connectors
from getting dirty when you are not using the connectors or while you are cleaning the chassis.
Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Before removing a card from the chassis, connect the equipment end of the strap to a bare metal,
unpainted surface on the chassis or rack-mount.
Handle components by the carrier edges only. Avoid touching the card components or the connector
pins.
When removing a module, place it on an antistatic surface or in a static-shielding bag. If the module
will be returned to the factory, immediately place it in a static-shielding bag.
Avoid contact between the modules and your clothing. The wrist-strap protects the card from ESD
voltages on the body only. The ESD voltages on your clothing can still cause damage.
