Preventing Electrostatic Discharge Damage
Preventing Electrostatic Discharge Damage
CompactFlash memory cards are sensitive to electrostatic discharge (ESD) damage. ESD damage, which can occur when electronic cards or components are handled improperly, results in complete or intermittent failures.
Follow these guidelines to prevent ESD damage:
•Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•Connect the equipment end of the strap to an unfinished chassis surface.
•Place a removed CompactFlash memory card on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.
•Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
•Do not remove the wrist strap until the installation is complete.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).
Tools and Equipment Needed
You need the following tools and equipment to remove and install CompactFlash memory cards:
•
•Antistatic bag or mat
•Number 2 Phillips screwdriver or flat blade screwdriver (only for internally mounted CompactFlash memory cards)
External CompactFlash Memory Card Installation and Removal
Complete the appropriate procedure below for installing or removing a CompactFlash memory card if your Cisco router has an external CompactFlash memory card.
