Downloading a System Image Using Xmodem or Ymodem
When you need a system image on the switch, but the switch does not have network access and you do
not have a software image on a Flash PC card, you can download an image from a local or remote
computer (such as a PC, UNIX workstation, or Macintosh) through the console port using the Xmodem
or Ymodem protocol.
The Xmodem and Ymodem protocols are used to transfer files and are included in applications such as
Windows 3.1 (TERMINAL.EXE), Windows 95 (HyperTerminal), Windows NT 3.5x
(TERMINAL.EXE), Windows NT 4.0 (HyperTerminal), and Linux UNIX freeware (minicom).
The Xmodem and Ymodem downloads are slow. Use them only when the switch does not have network
access. You can speed up the transfer by setting the console port speed to 38400 bps.
The Xmodem and Ymodem file transfers are performed from the ROM monitor with this command:
xmodem [-y] [-c] [-s data-rate]
where -y uses the Ymodem protocol, -c provides CRC-16 checksumming, and -s sets the console port
data rate.
The computer from which you transfer the supervisor engine software image must run terminal
emulation software that supports the Xmodem or Ymodem protocol.
This procedure shows a file transfer using the Xmodem protocol. To use the Ymodem protocol, include
the -y keyword with the xmodem command.
