CLI – Enter the following command to restart DHCP service.
Managing FirmwareYou can upload/download firmware to or from a TFTP server. By saving runtime
code to a file on a TFTP server, that file can later be downloaded to the switch to
restore operation. You can also set the switch to use new firmware without
overwriting the previous version.
Command Attributes
•TFTP Server IP Address – The IP address of a TFTP server.
•File Name –
The file name should not contain slashes (\ or /),
the leading letter of
the file name should not be a period (.), and the maximum length for file names on
the TFTP server is 127 characters or 31 characters for files on the switch.
(Valid characters: A-Z, a-z, 0-9, “.”, “-”, “_”)
Note: Up to two copies of the system software (i.e., the runtime firmware) can be stored
in the file directory on the switch. The currently designated startup version of this
file cannot be deleted.
Downloading System Software from a Server
When downloading runtime code, you can specify the destination file name to
replace the current image, or first download the file using a different name from the
current runtime code file, and then set the new file as the startup file.
Web – Click System, File, Firmware. Enter the IP address of the TFTP server, enter
the file name of the software to download, select a file on the switch to overwrite or
specify a new file name, then click Transfer from Server. To start the new firmware,
reboot the system via the System/Reset menu.
