Using A Configuration File - Lantronix SCS Reference Manual

Getting Started

2.5.2 Using a Configuration File

A configuration file can be downloaded from a TCP/IP host (via TFTP). Ensure that TFTP downloading is
enabled on your host and place the configuration file in a download directory.
To download a configuration file to the SCS using TFTP, use the Source command.
Local>> SOURCE "labsun:start.com"
If the configuration file must be downloaded each time the SCS boots, specify the filename using the Set/
Define Server Startupfile command. A TCP/IP filename must be specified in host:filename format, where
host is an IP address.
If lower-case or non-alphabetical characters are used, the filename must be
Note:
enclosed in quotes.
For example, to download the file config.sys from TCP/IP host 192.0.1.110, use the following command:
Local>> DEFINE SERVER STARTUP "192.0.1.110:config.sys"
The SCS is not usable during download attempts.
Note:
If the SCS has a nameserver defined, a text name may be specified as a TCP/IP host name. The SCS will
attempt to resolve the name at boot time; if it cannot resolve the name, the download will fail. To designate
a nameserver, see Set/Define IP Nameserver on page 12-39.
During its boot sequence, the SCS will load its operational code first, then attempt to download the
configuration file. If the attempt to download the configuration file is unsuccessful, the SCS may re-attempt
the download. By default, the SCS will make a total of six attempts to download the file (one initial attempt
and five re-attempts). To change this setting, use the Set/Define Server Startupfile Retry command.
Local>> DEFINE SERVER STARTUPFILE "TROUT\SYS:\LOGIN\config.sys" RETRY 10
If Retry is set to zero, the SCS can no longer be used; it will wait indefinitely for the configuration file to
download.
