Cable And Connector Protection; Safety Messages - Nortel Networks 2330 Manual Del Usario

Cable and connector protection

The following practices prevent damage to cables and connectors:
•
Use caution when connecting cables. Take care to ensure you insert
each cable connector in the correct port for the purpose you intend.
For example, ensure you connect LAN cables and connectors to LAN
ports on the Secure Router 2330/4134.
•
Support cables to prevent stress on the connectors. If you have
a high-density cable configuration, use an appropriate cable
management system to relieve stress on the cables. Also ensure that
cables are threaded neatly, and that you employ cable ties as required.
•
Do not exceed the bend radius recommended for the type of cable
installed.
•
Fiber-optic cables and connectors require special care:

Safety Messages

Cover connectors with rubber safety plugs when they are not
connected.
Before you install or replace fiber-optic cables, clean the
connectors.
Do not exceed the bend radius that is recommended for fiber-optic
cable. The acceptable bend radius for fiber-optic cable is ten times
its diameter, or 2.5 to 5 cm (1 to 2 in.). If you use a radius of less
than the recommended bend radius, a loss of signal integrity can
result. Loss of signal integrity caused by incorrect bend radius is
difficult to diagnose.
DANGER
Risk of injury by electric shock
Before working on this equipment, be aware of good safety
practices and the hazards involved with electrical circuits. Use
only power cords that have a grounding path. Ensure that the
switch is properly grounded before powering on the unit.
WARNING
Risk of eye injury by laser
Fiber optic equipment can emit laser or infrared light that can
injure your eyes. Never look into an optical fiber or connector
port. Always assume that fiber optic cables are connected to a
light source.
