AT-9108, AT-8518, AT-8525, and AT-8550 User’s Guide
14-7
To perform a serial download, you can optionally change the baud
rate to 38.4K using the
b
command, and then pressing the
s
key to
prepare the switch for an image to be sent from your terminal using
the XMODEM protocol. After this has completed, select the
g
command, to boot the image that is currently in RAM. The switch
restores the console port to 9600 bps, and begins the boot process.
Doing a serial download does not store an image into flash, it only
allows the switch to boot an operational image so that a normal TFTP
upgrade from CLI can then be performed.
Boot Option Commands
Table 14-1 lists the commands associated with switch boot options.
Table 14-1
Boot Option Commands
Command Description
show configuration Displays the current configuration to the terminal.
You can then capture the output and store it as a
file.
download bootrom <ipaddress>
<filename>
Downloads a Boot ROM image from a TFTP server.
The downloaded image replaces the BOOT ROM in
the onboard FLASH memory.
NOTE:
If this command does not complete
successfully it could prevent the switch from
booting.
download config <ipaddress>
<filename>
Downloads a previously saved ASCII configuration
file from a specific IP host.
download image [xmodem |
[<ipaddress> | <hostname>] <filename>]
{primary | secondary}
Downloads a new image by way of XMODEM using
the serial port, or from a TFTP server over the
network. If no parameters are specified, the image
is saved to the current image. XMODEM is not
supported over a Telnet session.
reboot {<date> <time> | cancel} Reboots the switch at the date and time specified.
If you do not specify a reboot time, the reboot
happens immediately following the command, and
any previously scheduled reboots are cancelled. To
cancel a previously scheduled reboot, use the
cancel
option.
