It is important to check Terminal Server settings before using the Ini-
Note:
tialize Reload command to ensure that you are reloading the correct
software file.

13.3.1 Reloading Sequence

If DHCP, BOOTP, or RARP is enabled on the Terminal Server, the Terminal Server will
request assistance from a DHCP, BOOTP, or RARP server before starting the download
attempts. the Terminal Server 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 Terminal Server can be rebooted with the code still in Flash ROM. The OK/ACT LED
will blink quickly while the Terminal Server is booting (and reloading code) and then
slowly when it returns to normal operation.
If you experience problems reloading Flash ROM, refer to Trouble-
Note:
shooting Flash ROM Updates on page 59.
13.3.1.1 TCP/IP
Before the Terminal Server downloads the new software, it will send DHCP, BOOTP, and/
or RARP queries (all are enabled by default). Next, the Terminal Server will attempt to
download the LES.SYS file using TFTP (Trivial File Transfer Protocol).
EZWebCon can also be used to reload software.
Note:
If a host provides DHCP, BOOTP, or RARP support, it can be used to set the Terminal
Server IP address (all methods) and loadhost information (BOOTP and RARP only).
Some BOOTP and TFTP implementations require a specific directory for the LES.SYS
file. See your host's documentation for instructions.
To manually configure the Terminal Server IP parameters for software reload, use the
following commands.
Local> SET PRIVILEGED
Password> SYSTEM (not echoed)
Local>> DEFINE SERVER IPADDRESS nnn.nnn.nnn.nnn
Local>> DEFINE SERVER SOFTWARE "/tftpboot/LES.SYS"
Local>> DEFINE SERVER LOADHOST nnn.nnn.nnn.nnn
Local>> LIST SERVER BOOT
Local>> INITIALIZE RELOAD
