Step 5

Reinstall the chassis on a rack or desktop.

 

Step 6

Reconnect network interface cables.

Formatting Procedures for Compact Flash Memory Cards

 

 

 

 

Cisco recommends that you format new Compact Flash memory cards to initialize them with either a

 

 

 

 

Class B Flash file system or a 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 Compact Flash memory card formatted with the standard DOS file system does not support booting

 

 

 

 

from the ROM monitor.

 

 

 

 

 

 

 

 

 

Determining the File System on a Compact Flash Memory Card

 

 

 

 

To determine the file system of a Compact Flash memory card in a Cisco 3631, enter the show flash:

 

 

 

 

command.

 

 

 

 

 

 

 

 

 

 

If the content of the Compact Flash memory card displays, the card was formatted with a Class B Flash

 

 

 

 

file system. If the geometry and format information of the card displays, the card was formatted with a

 

 

 

 

Class C Flash file system.

 

 

 

 

The following example shows output for an internal Compact Flash memory card formatted with a

 

 

 

 

Class C Flash file system:
