Downloading Switch Software
General Software Download Rules
■ Switch software that you download via the menu interface always goes
to primary flash.
■ After a software download, you must reboot the switch to implement the
new software. Until a reboot occurs, the switch continues to run on the
software it was using before the download commenced.
Note Downloading new switch software does not change the current switch con-
figuration. The switch configuration is contained in separate files that can also
be transferred. Refer to “Transferring Switch Configurations” on page A-25.
In most cases, if a power failure or other cause interrupts a flash image
download, the switch reboots with the image previously stored in primary
flash. In the unlikely event that the primary image is corrupted (which may
occur if a download is interrupted by a power failure), the switch goes into
boot ROM mode. In this case, use the boot ROM console to download a new
image to primary flash. Refer to “Restoring a Flash Image” on page C-77.
Using TFTP To Download Software from a Server
This procedure assumes that:
■ A software version for the switch has been stored on a TFTP server
accessible to the switch. (The software file is typically available at
www.hp.com/#Support.)
■ The switch is properly connected to your network and has already been
configured with a compatible IP address and subnet mask.
■ The TFTP server is accessible to the switch via IP.
Before you use the procedure, do the following:
■ Obtain the IP address of the TFTP server in which the software file has
been stored.
■ If VLANs are configured on the switch, determine the name of the VLAN
in which the TFTP server is operating.
■ Determine the name of the software file stored in the TFTP server for the
switch (for example, E0820.swi).
Note If your TFTP server is a UNIX workstation, ensure that the case (upper or
lower) that you specify for the filename is the same case as the characters
in the software filenames on the server.
