Although the metal carrier helps to protect the printed circuit boards from ESD, wear a preventive antistatic strap whenever handling the network processing engine or network services engine, I/O controller, port adapters, or Cisco uBR7200 series cable interface line cards. Ensure that the strap makes good skin contact and connect the strap’s clip to an unpainted chassis surface to channel unwanted ESD voltages safely to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Caution Make sure to tighten the captive installation screws on the network processing engine or network services engine, Cisco uBR7200 series cable interface line cards, and the I/O controller (use a number 2 Phillips or a
Following are guidelines for preventing ESD damage:
•Always use an ESD wrist strap or ankle strap when installing or replacing the network processing engine or network services engine, I/O controller, port adapters, or Cisco uBR7200 series cable interface line cards. Ensure that the ESD strap makes contact with your skin.
•Handle the network processing engine or network services engine, I/O controller, port adapters, or Cisco uBR7200 series cable interface line cards by their metal carrier edges and handles only; avoid touching the printed circuit board components or any connector pins.
•When removing the network processing engine or network services engine, I/O controller, port adapters, or Cisco uBR7200 series cable interface line cards, place them on an antistatic surface with the printed circuit board components facing upward, or in a static shielding bag. If you are returning an I/O controller, network processing engine or network services engine, port adapter, or Cisco uBR7200 series cable interface line card to the factory, immediately place it in a static shielding bag.
Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 to 10 megohms (Mohms).
