Cyclades-TS
Installation & Service Manual
NOTE: Due to space limitations, the new zImage file may not be downloaded with a different name, then
renamed. The TS searches for a file named zImage when booting and there is no room in flash for two zImage
files.
To make sure the downloaded file is not corrupted or that the zImage saved in flash is OK, run:
md5sum -b /proc/flash/zImage
Now check with the information present in the text file saved in the Cyclades site (e.g. zImage.132.md5sum). If
the numbers match the downloaded file is not corrupted.
D) Issue the command reboot
reboot
E) After rebooting, the new Linux kernel will take over. This can be confirmed by typing cat /proc/version to
see the Linux kernel version.
Troubleshooting
If the contents of flash memory are lost after an upgrade, please follow the instructions below to restore your
system:
a. Turn the TS OFF, then back ON
b. Using the console, during self test, press <Esc> after the Ethernet test
c. When the Watch Dog Timer prompt appears, press <Enter>
d. Choose the option Network Boot when asked
e. Enter the IP address of the Ethernet interface
f. Enter the IP address of the host where the new zImage file is located
g. Enter the file name of the zImage file on the host
h. Select the TFTP option instead of BOOTP (the host must be running TFTPD and the new zImage file must
be located in the proper directory. e.g. /tftpboot for Linux).
i. Accept the default MAC address by pressing <Enter>
