Reloading Software
The ETS stores software in Flash ROM to control the initialization process, operation, and command processing. The contents of Flash ROM can be updated by downloading a new version of the operational software via NetWare, TCP/IP, or MOP. Regardless of which protocol is used to update Flash ROM, the following points are important:
The Flash ROM software file name, ETS*.SYS, should not be changed.
The download file should be
There is a sixteen character length limit for the path name.
There is a twelve character limit for the filename.
Define commands must be used because Set configurations are cleared when the ETS boots. Use the List Server Boot command to check settings before rebooting.
Note: It is important to check ETS settings before using the Initialize Reload command to ensure that you are reloading the correct software file.
Reloading Sequence
If DHCP, BOOTP, or RARP is enabled on the ETS, the ETS will request assistance from a DHCP, BOOTP, or RARP server before starting the download attempts. The ETS will then try TFTP, NetWare, and MOP booting (in that order) provided that it has enough information to try each download method.
Downloading and rewriting the Flash ROM will take approximately two minutes from the time the Initialize command is issued. If the download file cannot be found or accessed, the ETS can be rebooted with the code still in Flash ROM. The OK/ACT LED will blink quickly while the ETS is booting (and reloading code) and then slowly when it returns to normal operation.
Note: If you experience problems reloading Flash ROM, refer to
Troubleshooting Flash ROM Updates on page 59.
TCP/IP
Before the ETS downloads the new software, it will send DHCP, BOOTP, and/or RARP queries (all are enabled by default). Next, the ETS will attempt to download the ETS*.SYS file using TFTP (Trivial File Transfer Protocol).
Note: EZWebCon can also be used to reload software.
If a host provides DHCP, BOOTP, or RARP support, it can be used to set the ETS IP address (all methods) and loadhost information (BOOTP and RARP only).
