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.

Installing Ethernet Routing Switch 4900 Series
• 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.

Technical specifications
The following table provides the technical specifications for the switches in this series. Ensure that
the area where you install the switch and where it operates meets these requirements.
Warning:
To avoid bodily injury from hazardous electrical shock and current, never remove the top of the
device. No user-serviceable components are inside.

noise
• No excessive dust
• Adequate power source within six feet; one circuit
required for each power supply (see table, AC
power specifications)
• At least 2 inches (5.08 cm) on each side of the
switch unit for ventilation
• Cables should be dressed to prevent blocking air
flow.
