Using ZMODEM

Using ZMODEM
Normally you use
FTP
to transfer files to and from the switch. It is faster than using the serial
port. A
ZMODEM
transfer can take several minutes. There are generally two situations which
would require you to use the serial port to load software:
• You do not have access to an
FTP
client or server program. If the switch is up and
running, you can use the File commands to load software.
• You have deleted the image software files in the switch. If you are in this situation, the
only way to load software is using
ZMODEM
with the boot line prompt.
To use
ZMODEM
, you must have a terminal emulator that supports the
ZMODEM
protocol.
There are many packages on the market and they operate differently; therefore instructions
on how to use them are beyond the scope of this document. Consult the user manual which
came with your terminal emulation software.
Before doing a serial port transfer, you should set the baud rate to the highest possible
(however, it is not recommended that you run it at 38.4 Kbps). Running at
19200
is twice as
fast as
9600
. To set the baud rate, use the
ser
command. For more information on the
ser
command, see Chapter 6, “Configuring Management Processor Modules.”
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
.
Using ZMODEM with the load Command
If your switch is up and running, log on to the switch. Type
ls
to list the files in flash
memory. If the file you are going to transfer exists, you must delete it first with the
rm
command.
From the File menu, type
?
to list the file commands. The command you use to start the
ZMODEM
process is
load
. The
load
command does not support speeds greater than 19,200
bauds.

**B0100000023be50
Activate the
ZMODEM
transfer according to the instructions that came with your terminal
emulation software. When the transfer is completed use
ls
again to list the file or files you
have loaded.
