Using the Rescue Software Image

WARNING!
The rescue image completely re-initializes the system. All data residing on the switch is cleared, including
configuration files, policy files, and other system-related files. Use this feature only with the guidance of Extreme
Networks Technical Support.
ExtremeWare XOS 11.1 introduces the concept of a rescue software image. The rescue software image
recovers a switch that does not boot up by initializing the internal compact flash and installing the
ExtremeWare XOS software on both primary and secondary images of the compact flash.
To use the rescue software image, you must be running ExtremeWare XOS 11.1 or later. Earlier versions
of ExtremeWare XOS do not support the rescue software image.
Before you begin the recovery process, collect the following information:
IP address, netmask, and gateway for the switch
●
IP address of the TFTP server that contains the ExtremeWare XOS image
●
ExtremeWare XOS image filename (the image has a .xos filename extension)
●
NOTE
The rescue process initializes the primary and secondary images with the ExtremeWare XOS software image. No
additional software packages or configuration files are preserved or installed. To install additional modular software
packages, BootROM images, and configuration files, see
information.
To recover the switch, you must enter the Bootloader and issue a series of commands. To access the
Bootloader:
1 Attach a serial cable to the console port of the MSM.
2 Attach the other end of the serial cable to a properly configured terminal or terminal emulator.
3 Reboot the MSM and press the spacebar key on the keyboard of the terminal during the boot up
process.
