Preventing Electrostatic Discharge Damage

Electrostatic discharge damage, which can occur when electronic boards or components are handled

improperly, can result in complete or intermittent failures.

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin

contact.

• When removing or installing a component, connect the equipment end of a ground strap to one

of the two ESD ground sockets located on the front sides of the upper card cage or to a bare metal

surface on the frame.

• If you plan to return a replaced component to the factory, immediately place it in a static shielding

bag to avoid ESD damage to the component.

• The wrist strap only protects the component from ESD voltages on the body; ESD voltages on

clothing can still cause damage.

Caution You should periodically check the resistance value of the antistatic strap. The

measurement should be between 1 and 10 megohms.

Tools and Parts Required

You need the following tools and parts to remove and replace the card cage assembly:

• ESD-preventive wrist strap

• 1/4-inch flat-blade screwdriver

• 3/16-inch flat-blade screwdriver

• 10-mm nutdriver

• Antistatic mat

• The replacement card cage assembly (Product Number: GSR12-CARDCAGE=)

You must remove all cards and power supplies from the old card cage assembly and install them in

the replacement card cage assembly. The replacement card cage ships with a new air filter installed.
