N o t e Downloading a new OS does not change the current switch configuration. The
switch configuration is contained in separate files that can also be transferred.
See “Transferring Switch Configurations” on page A-13.
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. See “Restoring a Flash Image” on page 18-25.
Using TFTP To Download an OS Image from a Server
This procedure assumes that:
■ An OS file for the switch has been stored on a TFTP server accessible to
the switch. (The OS file is typically available from the HP Procurve
website at
http://www.hp.com/go/hpprocurve.)
■ 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 OS 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 OS file stored in the TFTP server for the switch
(for example, G0101.swi).
N o t e 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 OS filenames on the server
.
