Safety Recommendations
Catalyst 8540 Chassis Installation Guide
3-6
Follow these guidelines to prevent ESD damage:
• Use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
• When removing any module, connect the equipment end of the ESD strap to the ESD
strap connection. (See Figure 3-2.)
• Handle carriers by the faceplates and carrier edges only; avoid touching the card or any
connector pins.
• When removing a module, place the removed module component side up on an
antistatic surface or in a static shielding bag. If the line module is to be returned to the
factory, immediately place it in a static shielding bag.
• Avoid contact between the line modules and clothing. The wrist strap only protects the
card from ESD voltages on the body; ESD voltages on clothing can still cause damage.
For safety, periodically check the resistance value of the antistatic strap. The measurement
should be between 1 and 10 megohms (Mohms).
