Recovering from a Software Failure
Recovering from a Software Failure
Switch software can be corrupted during an upgrade, by downloading the w rong file to the swi tch, 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 co rrupt 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.
This recovery procedure requires that you have physical access to the switch.
Step1 From your PC, download the software image tar file (image_filename.tar) from dell.com and 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 dell.com and Cisco.com, see the release notes.
Step2 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.EX1/cbs31x0-universal-mz.122-40.EX1.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

Step3 Connect your PC with terminal-emulation software supporting the Xmod em Pr otoc ol to t he sw itch
console port.
Step4 Set the line speed on the emulation software to 9600 baud.
Step5 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 chassis management
controller (CMC) GUI.
•Remove the switch or stack members from the enclosure.
On a nonstacking-capable switch, power off the switch by using the CMC GUI or r em ove the swit ch
from the enclosure.
Step6 Press the Mode button, and at the same time, power on the switch by using one of these methods:
•If you powered off the switch by using the CMC GUI, use the GUI to power on the switch or the
stack.
•If you powered off the switch by removing the switch or stack members from the enclosure, re-insert
the standalone switch or the stack members in the enclosure .
