Preventing Electrostatic Discharge Damage - Cisco 6160 Hardware Installation Manual

Safety Requirements

2.1.3 Preventing Electrostatic Discharge Damage

Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur
when electronic cards or components are improperly handled, results in complete or intermittent
failures. Use an antistatic strap when you handle any card or component.
Follow these guidelines to prevent ESD damage:
•
•
•
•
•
•
•
•
Caution Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1
and 10 megohms.

Always use an ESD ankle or wrist strap and ensure that the wrist strap makes good skin contact.
Connect the equipment end of the strap to the ESD jack on the front left side of the chassis, as shown
in Figure 2-1.
When you install a component, use available ejector levers or captive installation screws to properly
seat the bus connectors in the backplane or midplane. These devices prevent accidental removal,
provide proper grounding for the system, and help ensure that bus connectors are properly seated.
When you remove a component, use available ejector levers or captive installation screws to release
the bus connectors from the backplane or midplane.
Handle the I/O card by the edges only; avoid touching the printed circuit boards or connectors.
Avoid touching the printed circuit boards or connectors on the NI-2 cards or line cards.
Place a removed component board-side-up on an antistatic surface or in a static-shielding
container. If you plan to return the component to the factory, immediately place it in a
static-shielding container.
Avoid contact between the printed circuit boards and clothing. The wrist strap protects components
from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
