Cables And Connectors Protection; Electrostatic Discharge; Antistatic Material - Avaya Secure Router 4134 Hardware Installation

Cables and connectors 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:
- 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.

Electrostatic discharge

Electrostatic discharge (ESD) is the transfer of charge between objects at different electrical
potentials. ESD can change the electrical characteristics of a semiconductor device, and
degrade or destroy it. ESD can cause equipment to malfunction or fail.
To dissipate or neutralize electrostatic charges, use proper grounding and use conductive or
dissipative materials.
Use a grounded ESD wrist strap. When you use a wrist strap, any charge in your body can go
to ground rather than damage a hardware module.
When shipping the product, proper antistatic packaging shields the product from charge
caused by movement of the product within the shipping container.

Antistatic material

Antistatic material prevents electrical damage to equipment and therefore prevents the
interruption of normal operations in an electronic system.
