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 ant istatic 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.
