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.
Beginning with ExtremeWare XOS 11.3, the BlackDiamond 8800 family of switches support loading the
rescue image to the external compact flash memory card installed in the MSM. For more information
see
“Obtaining the Rescue Image from an External Compact Flash Memory Card—BlackDiamond 8800
Family of Switches Only” on page 624 .
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. This process takes a minimum of 7
minutes to complete. To install additional modular software packages, BootROM images (BlackDiamond 10K switch
only), and configuration files, see
Appendix A , “ Software Upgrade and Boot Options ” for more information.
Obtaining the Rescue Image from a TFTP Server
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. The
terminal settings are:
●
9600 baud
●
8 data bits
●
1 stop bit
●
no parity
●
XON/OFF flow control enabled
3 Reboot the MSM and press the spacebar key on the keyboard of the terminal during the boot up
process.
NOTE
You must press the spacebar key immediately after a power cycle of the MSM in order to get into the Bootloader
application.
As soon as you see the
BOOTLOADER ->
prompt (BlackDiamond 10K) or the
BootRom ->
prompt
(BlackDiamond 8800 family of switches), release the spacebar. From here, you can begin the recovery
process.
To obtain the rescue image and recover the switch:
1 Provide the network information (IP address, netmask, and gateway) for the switch using the
following command:
configip ipaddress <ip-address>[/<netmask>] gateway <gateway-address>
