Upgrading From The Boot Menu; Prerequisites - NEC QX-S5500G Series Installation Manual

Installation Guide
QX-S5500G Series Ethernet Switches
 NOTE:
The system automatically checks the compatibility of the Boot ROM image and the boot and system images
during the reboot. If you are prompted that the Boot ROM image in the upgrading image file is different than the
current Boot ROM image, upgrade both the basic and extended sections of the Boot ROM image for
compatibility. If you choose to not upgrade the Boot ROM image, the system will ask for an upgrade at the next
reboot performed by powering on the switch or rebooting from the CLI (promptly or as scheduled). If you fail to
make any choice in the required time, the system upgrades the entire Boot ROM image.

6.5 Upgrading from the Boot menu

You can upgrade the Boot ROM image and software images.
In this approach, you must access the Boot menu of each member switch to upgrade their
software one by one. If you are upgrading software images for an IRF fabric, using the CLI
is a better choice.
 TIP:
Upgrading through an Ethernet port is faster than through the console port.
