of computers that have a common, designated IP address routing prefix.

when the IP address does not match any other routes in the routing table.
<4>
Host Name : A hostname is a label that is assigned to a device connected to a computer
network and that is used to identify the device in various forms of electronic communication such

TFTP Server IP : Trivial File Transfer Protocol (TFTP) is a file transfer protocol, with the
functionality of a very basic form of File Transfer Protocol (FTP). This setting is the IP address of
the TFTP server.

TFTP File Name : This is the filename (case sensitive) of the firmware image that is placed on
the TFTP server and that must be downloaded by the TFTP client in 100AS-1 when performing a
firmware update.
<7>
Do TFTP and Update Firmware : This command will start the upgrade process. First the image
file will be downloaded into local RAM. If the image is not found or transfer fails, the upgrade
process will abort. Once the image is successfully downloaded, it is check to be sure it is the
proper image for the right model. At this point, if all is successful, the Flash will be erased and then
reprogrammed with the new image. Any power failure during the erase and re-write will result in
a 'bricked' unit. There is no recovery except to return to factory where the flash chip must be
manually replaced.
DO NOT ALLOW ANY POWER INTERRUPTION DURING FLASHING .
