Prevent Electrostatic Discharge Damage
Providing ground to the system prevents Electrostatic Discharge (ESD) to the chassis and cards. ESD damage
occurs as a result of improperly handled electronic components. Although the chassis is metal and provides
shielding to protect the boards from ESD, it is important than an antistatic ESD wrist strap be worn when han-
dling the interface cards, power supplies, or any other Tenor CMS equipment. In addition, the CMS chassis
offers a supplementary Earth Ground post to provide earth ground to the chassis, in case the power cord safety
earth ground is not available or as a secondary supplemental earth ground path.
ESD Antistatic Wrist Strap
The ESD antistatic wrist strap is worn on your wrist when handling any of the components. Use the following
precautions when using the ESD strap:
•
When handling peripheral boards, touch only the edges. Do not touch any other components on the
board, including the connector pins.
•
Place the peripheral board in a static shielding bag or on an antistatic surface.
•
Avoid any component touching your clothing. The Ground Strap protects components from ESD on the
body; ESD damage from clothing is still possible.
Use the Ground Strap as follows:
1. Place the wrist strap end of the ESD strap around your wrist. Ensure strap fits snugly around your wrist
and the metal contact is against your skin.
2. Plug in the other end to either of the Ground Strap ports located on the chassis (front and rear).
Provide Grounding
The chassis provides an Earth Ground post to provide an additional connection to an approved safety earth
ground. Connect earth ground to the post on the rear of the chassis called Supplemental Earth Ground.
