PREVENTING ELECTROSTATIC DISCHARGE DAMAGE
Electrostatic discharge (ESD) damage, which occurs when electronic cards or
components are improperly handled, can result in complete or intermittent system
failures. The line cards consist of printed circuit boards with Integrated Circuits
(IC) and should be handled at edges or faceplate only.
Warning: Always tighten the captive tabs and levers on all the devices. These tabs and levers
prevent accidental removal, provide proper grounding for the system, and help ensure
that the cards are properly fitted in the shelf.
Follow the guidelines given below for preventing ESD damage:
• Always use an ESD wrist strap or ankle strap and ensure that it makes good skin
contact and is properly grounded.
• Do not touch the printed circuit board, and avoid contact between the printed
circuit board and your clothing.
• Ensure the line cards are fully inserted in their respective chassis slots and the
thumb screws are tightened.
Warning: For safety, periodically check the resistance value of the antistatic strap. The
measurement should be in 1 and 10 mega ohms range.
