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:

•ESD-preventive wrist strap

•Antistatic bag or mat

•Number 2 Phillips screwdriver or flat blade screwdriver (only for internally mounted CompactFlash memory cards)

Formatting Procedures for CompactFlash Memory Cards

The following sections describe formatting procedures for internal and external CompactFlash memory cards.

Formatting Procedures

Cisco recommends that you erase (Class B) or format (Class C) new CompactFlash memory cards to initialize them with either a Class B or Class C Flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the Flash.

The Class B Flash file system is also known as the low end file system (LEFS).

The Class C Flash file system is similar to the standard DOS file system.

Note A CompactFlash memory card formatted with the standard DOS file system does not support booting from the ROM monitor.

Determining the File System on a CompactFlash Memory Card

To determine the file system of an external CompactFlash memory card, enter the show slot0: all command. To determine the file system of an internal CompactFlash memory card, enter the show flash: all command.

•If geometry and format information is not displayed, the card is formatted with a Class B Flash file system.

•If geometry and format information is displayed, the card is formatted with a Class C Flash file system.

The following examples show outputs for Class B and Class C Flash file systems:
