Netgear XCM8810 - 8800 SERIES 10-SLOT CHASSIS SWITCH ユーザーズマニュアル

The switch deletes the old configuration files on the backup node only upon a successful file 
synchronization. If an error occurs, the switch does not delete the old configuration files on 
the backup node. For example, if you install a backup node that contains different 
configuration files from the primary node, the old configuration files are deleted after a 
successful bootup of the backup node. 

To see a complete listing of the configuration files on your system, use the 

ls

 command.

Accessing the Bootloader

The Bootloader of the switch initializes certain important switch variables during the boot 
process. In the event the switch does not boot properly, some boot option functions can be 
accessed through the Bootloader. 

Interaction with the Bootloader is required only under special circumstances and should be 
done only under the direction of NETGEAR Customer Support. The necessity of using these 
functions implies a nonstandard problem which requires the assistance of NETGEAR 
Customer Support.

To access the Bootloader menu:

Attach a serial cable to the console port of the switch.

Attach the other end of the serial cable to a properly configured terminal or terminal 
emulator, power cycle the switch, and press the spacebar key on the keyboard of the 
terminal during the bootup process. 

As soon as you see the 

BootRom ->

 prompt, release the spacebar. You can issue a series 

of commands to: 

View the installed images.

Select the image to boot from.

Select the configuration to use.

Load a recovery image over the management port.

To see a list of available commands or additional information about a specific command,

The following describes some ways that you can use the Bootloader:

Viewing images—To display a list of installed images, use the 

show image

 command. 

Selecting an image—To change the image that the switch boots from in flash memory, 

use the 

boot {image number}

 command. If you specify 

image number

, the specified image 

is booted. If you do not specify an image number, the default image is booted. 

Selecting a configuration—To select a different configuration from the one currently 

running, use the 

config {alt | default | <filename> | none}

 command. This 

command is useful if you experience a problem with the current configuration and there is 
an alternate configuration available.
