Electrical Safety

• Handle line cards by the faceplates 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 ohms.

Electrical Safety

All system components are hot-swappable. They are designed to be removed and replaced while the

system is operating without presenting an electrical hazard or damage to the system.

Follow these basic guidelines when you are working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.
