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.
