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 world-readable on the host.
‹ 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).
