Removing and Installing Compact Flash Memory Cards
This section describes installing and replacing compact flash (CF) memory cards in Cisco CGR 2010
routers. It contains the following sections:
• Preventing Electrostatic Discharge Damage, page 5-2
• Removing a Compact Flash Memory Card, page 5-3
• Installing a Compact Flash Memory Card, page 5-5
Preventing Electrostatic Discharge Damage
Compact flash memory cards are sensitive to electrostatic discharge (ESD) damage, which can occur
when electronic cards or components are handled improperly, results in complete or intermittent failures.
To prevent ESD damage, follow these guidelines:
• 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 compact flash 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).
