Electrostatic Discharge Prevention - Avaya 5900 Series Installing Manual

The USB Type A port enables switch administrators to perform tasks that were previously completed
through TFTP with a commonly available USB Mass Storage Device (also known as a flash drive or
thumb drive). These tasks include:
• software download
• syslog backup
• ASCII configuration file generation and download
File and system operations are limited by the size of the USB device in use. Only USB drives that
comply with the Mass Storage sub-section of the USB 1.1, USB 2.0, and USB 2.1 specification are
supported. Support is not extended to third-party devices that do not comply with these standards.
Consult the documentation provided with the USB drive to ensure compliance with these standards.
Important:
The micro-USB port on the front panel of the Ethernet Routing Switch 5900 Series models is not
enabled.

Electrostatic discharge prevention

This module provides information and procedures for the prevention of electrostatic discharge
during the installation process.
Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment
and impair electrical circuitry. These electrostatic voltages can result from friction, including, but not
exclusive to, pulling cabling through conduits, walking across carpeted areas, and building up of
static charge in clothing. ESD damage occurs when electronic components are improperly handled
and can result in complete or intermittent failures. While networking equipment is commonly
designed and tested to withstand common mode ESD events, voltage sometimes can be
discharged to some connector pins but not others, or to some pins before others, which has the
potential to damage the networking equipment.
To protect the Avaya Ethernet Routing Switch against ESD damage, take the following preventive
measures before connecting any data cables to the device:
• Always use antistatic wrist straps. Make sure the strap is adjusted to provide good skin contact.
• Ensure that work surfaces and equipment racks are properly grounded for protection against
electrostatic discharge. The common point must be connected to the building ground wire. In a
properly wired building, the nearest reliable ground is typically at the electrical outlet.
• Avoid contact between equipment and clothing. The wrist or ankle strap only protects the
equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.
• Avoid touching any connector pins.
• Do not remove the wrist or ankle strap until the installation is complete.
With new cable installations, Avaya recommends that the use of an ESD discharge cable to reduce
the potential for damage from static that can build up in cables. See the following figure.
