Upgrading Using XModem/YModem File Transfer Method
You can use the XModem/YModem file transfer method to load new system
software to the CPU component.
Upgrading using the XModem/YModem file transfer method includes two
major tasks:
•
First, you set up the cabling and connections between the PC workstation
and the Access Concentrator system CPU component, start up the VT100
terminal emulation software on the PC workstation, and ensure you have
communication between the two devices (see the following procedure,
“Steps to Set Up for the File Transfer Process”).
•
Second, you perform the file transfer process for the new software
upgrade files to the Access Concentrator system, and the upgrading
process on the CPU component (see the procedure ”Steps to Transfer the
Software Upgrade Files to the System” on page 7-10).
