Caution
Because of the limited size of the flash memory, it is strongly recommended
that other applications available to the new and existing users be configured
to prevent writing to the local file system. For the same reason, it is also
recommended that extreme care be exercised when changing configuration
settings of the factory-installed applications.
Remote Administration and Firmware Upgrades
Rapport Administrative Software
Rapport is a full-featured remote administration tool set available from Wyse Technology.
It accesses the terminal through the Rapport Agent, PXE, and VNC server utilities
installed on the terminal. Rapport allows the terminal administration functions (including
firmware upgrades) to be performed without requiring an administrator to visit the
individual terminal sites.
For specific information on using Rapport, consult the Rapport help documentation.
For local custom fields that may be accessed by Rapport, refer to “Custom Fields” in
“Control Panel Extended Selections”.
Add-on Modules
If it is desired to install an add-on module, an administrator must use the built-in Rapport
packages for administering the terminal. Disable the write filter and enable the write filter
as needed to save the changes.
Firmware Upgrades
Intel's Preboot Execution Environment (PXE) is a protocol that defines interaction
between TCP/IP, DHCP and TFTP to enable a client to download a preboot environment
from a server.
PXE client is installed on the terminal and the PXE server component is part of the
Rapport Administrative Software suite.
Note
Citrix ICA auto update does not function for the ICA client installed on the
terminal; updates are implemented through the standard firmware upgrade
process.
