Installation Guide
QX-S5500G Series Ethernet Switches
 NOTE:
The switch always attempts to boot with the main images first. If the attempt fails, for example, because the

main images are not available, the switch tries to boot with the backup images. An image with the none
attribute is only stored in flash memory for backup. To use it at reboot, you must change its attribute to main
or backup.
If an image with the same attribute as the image you are loading is already in the flash memory, the attribute

of the old image changes to none after the new image becomes valid.
6) Enter 0 in the Boot menu to reboot the switch with the new software images.
