Using Flash Cards with the Network Station

3.4.1 Scenario Objectives
In this scenario, we want to accomplish the following objectives:
• Configure a Network Station to boot from another Network Station
containing a Flash card.
• Load the executable modules required for 5250, 3270 and VTxxx
emulators from the Flash card.
• Use ACTLogin and server separation to authenticate the user at the
central site.
• Load the user configuration, fonts and other volatile data from the central
site, allowing the data to be maintained centrally.

3.4.2 Scenario Advantages
This scenario has the following advantages:
• Users at the remote location experience fast boot up times using peer
boot.
• The executable modules are contained on the Flash card in the serving
Network Station, and are not loaded over the WAN.
• The WAN traffic is reduced.
• User configuration data and preferences remains on the central system,
simplifying the management of the data.
• User authentication is maintained and conducted on the central system.
