Installing and Formatting Compact Flash Memory Cards in Cisco 2691 Routers

Installing and Formatting Compact Flash Memory Cards in
Cisco 2691 Routers
The operation system software, or image, is stored in Flash memory on a compact Flash memory card.
This section describes how to install compact Flash memory cards in Cisco 2691 routers, how to format
the cards into a Class B Flash file system (low end file system) or a Class C Flash file system (similar
to DOS), and how to perform file and directory operations in each file system. In Cisco 2691 routers,
the compact Flash memory card mounts on a connector on the system board. You can install a compact
Flash memory card with 32-, 64-, or 128-MB of memory.

Preventing Electrostatic Discharge Damage

Compact Flash memory cards can be damaged by electrostatic discharge (ESD). ESD damage, which
can occur when electronic cards or components are handled improperly, can cause complete or
intermittent failures.
Follow these guidelines to prevent ESD damage:
•
•

•
For safety, periodically check the resistance value of the antistatic strap. The measurement should be

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.
