Installing and Replacing CompactFlash Memory Cards on Cisco 1805 DOCSIS Cable Router
This chapter describes installing and replacing CompactFlash memory cards in Cisco 1805 DOCSIS cable router. You can perform these procedures when the router has been installed in its working location with all power and interface cables connected. This chapter contains the following sections:
•Preventing Electrostatic Discharge Damage, page

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 intermittent or complete 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 (Mohms).
