6-12 ExtremeWare EPICenter Software Installation and User Guide
Configuration Manager
The Configuration Manager will display an error if you attempt an incremental
download on a switch running a version of ExtremeWare prior to 6.0.
Creating an Incremental Configuration File
The purpose of a incremental configuration is to provide a set of known, standard
configuration settingsyou can downloadto adeviceto restore it or initializeit to a known
software state.
To create an incremental configuration, you can start with a configuration file you have
uploaded, or one of the standard configuration. You can edit it, if needed, to reflect the
basicconfigurationsettingsyouwanttouseas yourbaselineconfiguration,andto remove
settings you don’t want changed.
Incremental configuration files must be stored in the
<tftp_root>\baselines directory,
where
<tftp_root> is the location of your TFTP server. By default, <tftp_root> is
<EPICenter_install_dir>\user\tftp.
<EPICenter_install_dir> is the EPICenter installation directory, by default epc3_1.
Thus, if you installed the EPICenter server under Windows NT using the default
installation path, your incremental configurations must be in
epc3_1\user\tftp\baselines, unless you have reconfigured your TFTP root directory.
You can name an incremental configuration file any way you want.
If you have reconfigured your TFTP root directory (see “Configuring the TFTP
Server” on page 6-16), the baselines subdirectory will be found directly below (as a
child of) your TFTP server root directory.
Upgrading Device Software Images
TheExtremeWaresoftwareimagecontainstheexecutable codethatruns ontheswitch. An
image comes pre-installed from the factory on every switch. You can upgrade this image
by downloading a new version through the Configuration Manager. You can download
the image into either the primary or secondary image, and specify whether the switch
should be rebooted to use the new image.
The BootROM software initializes certainimportant switch variables during the switch
boot process.
