Switch Configuration SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide
➽ Note!
When upgrading the boot code, append the string
*boot
to the filename when
entering the filename. For example, to download the 2.3 bootcode to the switch,
type the following:
main image download filename: STS_230.bt*boot
Execute <name> Download/Upload
This command is displayed on the sub-screens that are opened from the
TFTP
Download/Upload
screen.
The command
Execute <name> Download/Upload
initiates the download or
upload for a single switch only. On a locally attached console, the screen displays
the block it last received from the server (block 0 if no reply has been received) until
the last packet arrives. The switch does not attempt to load any of the image into
flash memory until it receives the final packet. Therefore, if interrupted or
cancelled for any reason before the last packet, the previous system image remains
intact in flash memory.
Once the last packet has arrived, the switch immediately begins clearing flash
memory and loads it with the new image.
The switch will continue to use its previously loaded software until its next reset by
whatever means. The newly stored image is not functional until a reset is
performed.
When downloading configuration, all configurable parameters will be replaced
with this new configuration, the message log will be cleared and the switch must be
reset immediately after.
While uploading configuration files, the switch can continue normal operation.
Note that some TFTP servers requires that the file exist before it will allow
uploading. The switch will append the box number (.#) to the filename, that is,
stand-alone boxes will append “.1”.
➽ Note:
Be careful - if the process is interrupted during this time, the stored image
may be corrupted and the SmartStack STS16-20D/STS16-20R will not be able to
boot normally! If this happens, it is necessary to download the switch via its Out-
of-Band Management port since the system boot image does not contain software
capable of operating the network hardware of the switch or interpreting IP and
TFTP protocols. During this fairly short vulnerable period of time, the diagnostic
LED on the switch blinks to indicate the clearing (slow blink) and reloading (faster
blink) of flash memory. The screen also displays messages indicating these events.
