Installing the Avaya Ethernet Routing Switch
including, pulling cabling through conduits, walking across carpeted areas, and building static
charge in clothing. When you improperly handle electronic components, ESD damage occurs
and can result in complete or intermittent failures. While networking equipment is commonly
designed and tested to withstand common mode ESD events, voltage can sometimes
discharge to some connector pins, which can potentially damage the networking equipment.
Caution:
To protect the Avaya Ethernet Routing Switch against ESD damage, take the following
measures before you connect data cables to the device:
• Always use antistatic wrist straps. Make sure you adjust the strap to provide good skin
contact.
• Ensure that you properly ground work surfaces and equipment racks for protection
against electrostatic discharge. You must connect the common point 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 protects only
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.
Preventing electrostatic damage in new cable installations
With new cable installations, Avaya recommends that you use an ESD discharge cable to
reduce the potential for damage from static, that can build up in cables. The following figure
illustrates an ESD cable.
