Installing CompactFlash Memory Cards in Cisco 3800 Series Routers This document describes how to remove and install CompactFlash memory cards in Cisco 3800 series integrated services routers. It contains the following sections: • Preventing Electrostatic Discharge Damage, page 73 • Removing CompactFlash Memory Cards, page 74 • Installing CompactFlash Memory Cards, page 75 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: • 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 (Mohm).

integrated services routers. It contains the following sections:

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:
•
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 (Mohm).
