Overview
Xmodem Requirements
The Controller update software file must be located on a compact disk (CD), hard drive, or file
server accessible by the craft terminal or management computer through a file name or path name.
File transfers are accomplished using Xmodem protocol, which is supported by most terminal
emulation programs, such as Microsoft HyperTerminal. Using an RS-232 management session, the
operator sends a CLI “load xmodem” command to the Access Navigator. The operator then
instructs the terminal program to send the update file. Updating the standby Controller will take
about 45 minutes.
Event Log
During the software update process, the two Controller cards will momentarily be operating with
different software. The Access Navigator event log will contain an entry stating that one of the
Controllers is Incompatible. This message is normal and can be ignored if both Controllers are
updated with the same software.
