Recovering from a Software Failure
Recovering from a Software Failure
Switch software can be corrupted during an upgrade, by downloading the wrong file to the switch, and
by deleting the image file. In all of these cases, the switch does not pass the power-on self-test (POST),
and there is no connectivity.
This procedure uses the Xmodem Protocol to recover from a corrupt or wrong image file. There are many
software packages that support the Xmodem Protocol, and this procedure is largely dependent on the
emulation software that you are using.
You can also connect a terminal or PC to the switch to the Advanced Managment Module (AMM)
through an Ethernet connection. For details about using the internal Ethernet management port, see the
“Using the Internal Ethernet Management Port” section on page 10-19 and the hardware installation
guide.
This recovery procedure requires that you have physical access to the switch.
Step 1 From your PC, download the software image tar file (image_filename.tar) from ibm.com or Cisco.com.
The Cisco IOS image is stored as a bin file in a directory in the tar file. For information about locating
the software image files on ibm.com or Cisco.com, see the release notes.
Step 2 Extract the bin file from the tar file.
• If you are using Windows, use a zip program that can read a tar file. Use the zip program to navigate
to and extract the bin file.
• If you are using UNIX, follow these steps:
1. Display the contents of the tar file by using the tar -tvf image_filename.tar UNIX command.
switch% tar -tvf image_filename.tar
2. Locate the bin file, and extract it by using the tar -xvf image_filename.tar image_filename.bin
UNIX command.
switch% tar -xvf image_filename.tar image_filename.bin
x cbs31x0-universal-mz.122-40.EX2/cbs31x0-universal-mz.122-40.EX2.bin, 3970586
bytes, 7756 tape blocks
3. Verify that the bin file was extracted by using the ls -l image_filename.bin UNIX command.
switch% ls -l image_filename.bin

Step 3 Connect your PC with terminal-emulation software supporting the Xmodem Protocol to the switch
console port.
Step 4 Set the line speed on the emulation software to 9600 baud.
Step 5 On a stacking-capable switch, power off the switch by using one of these methods:
• Power off the standalone switch or the entire switch stack by using the AMM GUI.
• Remove the switch or stack members from the enclosure.
On a nonstacking-capable switch, power off the switch by using the AMM GUI or remove the switch
from the enclosure.
