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.
To prevent ESD damage, follow these guidelines:
•

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms (Mohm).

Removing a CompactFlash Memory Card

To remove a CompactFlash memory card from the chassis, perform the following steps. See
Do not remove a CompactFlash memory card from the chassis while it is being accessed. A blinking CF

LED indicates that the CompactFlash memory is being accessed. Removing the CompactFlash memory
card from the router while it is being accessed can damage your router.
Step 1 Press the ejector button next to the CompactFlash memory card. The ejector button moves outward so
that it projects from the panel.
Press the ejector button again. This ejects the CompactFlash memory card partway out of its slot.
Step 2

Installing a CompactFlash Memory Card
Always use an ESD wrist 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 your 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.
