Module Protection; Cables And Connectors Protection - Avaya Secure Router 4134 Installation Manual

Avaya Secure Router 4134 regulatory information and safety precautions

Module protection

The following practices prevent equipment damage when you work on the Avaya Secure
Router 4134:
• Always wear a grounded antistatic wrist strap when you handle modules.
• Always set modules on appropriate antistatic material.
• Handle modules by the faceplate and handles. Do not touch pins or electrical
connections.
• Do not leave interface module or power supply module slots empty. You must fill all slots
with modules or slot covers to maintain safety compliance, proper cooling, and
electromagnetic interference (EMI) containment in the shelf.
• Ensure that your environment meets the requirements for temperature, humidity, and
cleanliness. See
• Do not overtighten thumb screws or lug nuts. Tighten screws and nuts until they are snug,
plus a quarter turn. If you use a power tool to tighten screws, use a low torque setting of
2 to 3 in–lb (0.226 to 0.339 N-m).

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 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.
