4.8.2 Updating the Non-Active Image
All of the update methods supported by the active image (image1 by default) are
also supported for the non-active image (image2).
4.8.3 Fabric 1G/10G Auto-negotiation
The Fabric networks support both 1Gigabyte and 10Gigabyte operation. No
configuration is required to put the switch into either a 1Gigabyte or 10Gigabyte
mode. The switch will dynamically connect at the appropriate speed.
4.9 Network Boot
The switch supports network booting. This feature can be used to test updates to
FASTPATH without installing them. Updates containing changes to uBoot, Linux, or
the IPMC must be installed to the flash before they can be used.

Tftpd is the standard TFTP server for Linux and Solaris.

http://www.solarwinds.net) offers a free TFTP server.
2. Place the update image on the TFTP server.
It will have a .tgz file extension.
3. Connect to the serial management port of the network to be updated, and
connect the MGMT port to the update network.
4. Reboot the switch using the reboot button, hotswap handle, or reload
command.
5. As the switch boots, press number 2 to enter the Utility Menu.
6. Press number 8 to change the boot method.
7. Press number 3 to select network as the boot method.
8. Enter the information for your TFTP server.
For host IP, you can enter dhcp if you would like to use DHCP to obtain a valid
IP address.
