Caution
Always tighten the captive installation screws on all system components when you are installing them. These screws prevent
accidental removal of the module, provide proper grounding for the system, and help to ensure that the line card connectors
are properly seated in the backplane. Captive screws should be torqued to 6-8 in-lbs to ensure proper grounding and mechanical
support. Never use cordless or corded drills to tighten screws; power screwdrivers and hand tools are acceptable.
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your
body before you touch any of your system components. As you continue to work on your system, periodically touch an unpainted
metal surface on the computer chassis.
The following guidelines can prevent ESD damage:
• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from
the chassis, connect the equipment end of the strap to the ESD plug at the bottom of the chassis below the power entry modules.
Ensure that the chassis or rack or both have a grounding cable installed.
• Handle line cards by the faceplate and carrier edges only; avoid touching the card components or any connector pins.
• When removing a card, place the removed module component-side-up on an antistatic surface or in a static-shielding bag. If the
module will be returned to the factory, immediately place it in a static-shielding bag.
• Avoid contact between the modules and clothing. The wrist-strap protects the card from ESD voltages on the body only; ESD
voltages on clothing can still cause damage.
• When transporting a sensitive component, first place it an antistatic container or packaging.
• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10
megohms.
