Managing System Files Loading Software onto the Switch
OmniSwitch 7700/7800/8800 Switch Management Guide April 2006 page 2-23
Using Zmodem
A Zmodem application has been included with your switch software so that new programs and archives
can be uploaded through the switch’s serial console port. You may want to use the switch’s console port to
load software using Zmodem when your system is having problems and the FTP transfer method does not
work or when the switch’s Ethernet Management port is either not functioning or not configured.
To use Zmodem, you must have a terminal emulator that supports the Zmodem protocol. There are many
Zmodem products available that operate differently. Consult the user manual that came with your termi-
nal emulation software for details.
Note. If a file you are transferring already exists in the switch’s flash memory, you must remove the file
before transferring the new file via Zmodem.
To transfer a file via Zmodem, complete the following steps.
1 Connect your terminal emulation device containing the Zmodem protocol to the switch’s console port.
2 Start the Zmodem process on your switch by executing the rz command.
-> rz
A screen similar to the following will appear.
Upload directory: /flash
rz ready to receive file, please start upload (or send 5 CTRL-X’s to abort).

3 Transfer the files using your terminal emulation software. The following will display.
ZMODEM file transfer successful,
Hit <RETURN> to exit...
When the transfer is complete, you can use the ls command to verify that the new files were loaded
successfully. To abort a Zmodem session enter Ctrl-X five times in succession.
Note. Files transferred via Zmodem are loaded into the flash directory. Before the new files can be used
by the switch, you must transfer them to the switch’s /flash/working directory and execute the install
command.
